Sugar plays an appealing role in the daily diet of many people. We are sensitive to sweetness, but excessive sugar intake can have far-reaching health consequences over time. A growing body of scientific studies shows that long-term high sugar consumption is linked to an increased risk of obesity, metabolic disorders, type 2 diabetes, cardiovascular diseases, certain types of cancer, and even depressive symptoms and cognitive decline.
Yet, the daily sugar intake of many people is significantly higher than recommended. In Western countries, adults consume an average of 22 to 30 teaspoons of added sugars per day. This stands in stark contrast to the guidelines of health organizations, which advocate a maximum of 6 teaspoons (25 grams) for women and 9 teaspoons (36 grams) for men. The World Health Organization (WHO) even recommends getting less than 10% of daily calories from free sugars, and for additional health benefits, less than 5% (about 25 grams).
In this overview, we delve deeper into what happens in the body with a high sugar intake, the short- and long-term impact of refined sugars, and how sugar contributes to the development of chronic conditions such as type 2 diabetes. We discuss how a holistic nutritional approach can help break free from the vicious cycle of sugar dependency. We also explore what a sugar-free lifestyle entails — including the benefits and pitfalls — and which scientifically researched alternatives exist, such as stevia and xylitol, including points of attention when using them.
What happens in your body with a high-sugar diet? (Insulin response and the sugar cycle)
When you eat or drink something sweet — for example, soda or pastry — your blood sugar level rises rapidly. Especially with refined sugars, which contain hardly any fiber, glucose is immediately absorbed into the blood. This spike (hyperglycemia) causes the pancreas to release insulin, the hormone that helps glucose enter the cells for energy or storage.
During a sharp sugar spike, the body can sometimes produce so much insulin that the blood sugar level drops too low. This sharp drop, also known as a sugar crash or reactive hypoglycemia, causes hunger and a craving for new, quick energy. This creates a vicious cycle of high-sugar foods, rapid spikes, energy crashes, and a recurring craving for sugar.
Refined sugars like table sugar, high-fructose corn syrup, or white bread provide quick energy but hardly any satiety. They contain barely any dietary fiber or micronutrients. Natural sources of sugar — such as fruit or dairy — on the other hand, also offer fiber or protein, which slows down absorption. That difference matters for how your body processes sugar and how long you stay full.
The result is a moderate rise in blood sugar and a less severe insulin spike. As Harvard scientists state: “Foods containing natural sugars (like fruit and vegetables) naturally contain fiber, causing your body to absorb the sugars more slowly. Added sugar, on the other hand, lacks fiber and is absorbed much more quickly. This can cause blood sugar to spike, followed by an insulin spike, which promotes hunger.” Source.
Besides these physical reactions, the mind also plays a role. Sweet flavors activate the reward system in the brain through the release of dopamine. This provides a brief feeling of pleasure, similar to what we see with addictive substances. Although sugar addiction is not a recognized diagnosis, many people recognize how hard it is to stop after just one cookie.
Sugar dependency often manifests in an increasing desire for sweets, larger portions, and a feeling of losing control. Former smokers or ex-drinkers sometimes use sugar as a replacement ‘comfort’, which reinforces the addictive tendency. Although the body needs glucose as an energy source, added sugars are unnecessary and can actually be harmful when overconsumed. Therefore, the distinction between natural and added sugars is essential for anyone who wants to approach nutrition more mindfully.
Sugar is not just a food. It is a biologically active, addictive substance that deeply affects your metabolism. ~ Dr. Mark Hyman
Over time, chronically high sugar intake can disrupt the body’s natural balance. The cells then respond less and less well to insulin — a condition known as insulin resistance. The pancreas has to produce extra insulin to regulate blood sugar. Initially, you often notice little of this, except perhaps energy crashes or increased appetite — but in the long term, this process can lead to pre-diabetes or ultimately type 2 diabetes.
It is therefore not surprising that type 2 diabetes is closely linked to excessive sugar consumption. Studies show that frequent intake of sugary drinks can disrupt the insulin response and is associated with higher fasting glucose and insulin levels. It also appears that the more sugar someone consumes, the greater the risk of type 2 diabetes. Conversely, reducing added sugars in the diet is associated with a lower number of new diabetes cases.
Refined sugars and their impact on health
Refined sugars are added sugars that are introduced to foods during the manufacturing process — such as table sugar, corn syrup, or sugar in soda, cookies, and ready-made sauces. They provide quick energy but, when overconsumed, contribute to various health problems. One of the most immediate effects is weight gain. High-sugar products are often high in calories without being satiating. That makes it easier to unknowingly overeat.
Studies show that adults who consume less sugar generally have a lower body weight. Conversely, high sugar intake is clearly linked to weight gain. This pattern is also visible in children: those who drink many sweetened beverages are more likely to be overweight than children who avoid these drinks.
Liquid sugar sources like soda or juice are particularly risky here. They provide calories but hardly give a satiety signal. The body registers liquid sugar less effectively than solid food, meaning you unknowingly consume more calories. That is why sugary drinks are strongly linked to the development of obesity and type 2 diabetes. The dietary advice is therefore clear: limit the use of sweet drinks as much as possible.
Sugar is not just a food. It is a biologically active, addictive substance that deeply affects your metabolism. ~ Dr. Mark Hyman
But the effect of sugar doesn’t stop at weight and diabetes. A high sugar intake also contributes to low-grade chronic inflammation — a silent inflammatory response in the body linked to cardiovascular diseases and possibly certain forms of dementia. In the elderly, a connection was even found between high sugar intake and an increased risk of frailty.
Dental health also suffers from frequent sugar consumption. Especially when sugars are consumed throughout the day — for example, by regularly snacking or drinking sweetened beverages — the teeth don’t get enough time to recover. Sugar feeds bacteria that produce acids and attack tooth enamel, which greatly increases the risk of cavities. According to nutrition experts, it is wise to limit the number of sugar intake moments to a maximum of seven per day (including main meals) to protect the teeth.
Finally, there are also metabolic changes associated with excessive sugar intake. In the Framingham Heart Study, regular consumption of soda was shown to lead to more fat storage in the liver. This so-called non-alcoholic fatty liver disease (NAFLD) occurs when excess fructose — especially from high-fructose corn syrup — is converted into fat by the liver. At the same time, researchers saw an increase in dyslipidemia, with higher triglycerides and lowered HDL cholesterol in people who consumed a lot of sugary drinks.
These changes — such as fatty liver and dyslipidemia — are known risk factors for cardiovascular diseases. The link between sugar and heart problems is becoming increasingly well-supported. Although sugar indirectly contributes via obesity and diabetes, there are also indications of direct effects: persistently high blood sugar levels can damage blood vessel walls and raise blood pressure.
A large-scale umbrella review of dozens of studies reported clear harmful associations between sugar consumption and as many as 45 different health outcomes — including endocrine disorders, cardiovascular diseases, certain types of cancer, and neurological and dental conditions.
For instance, it was found that each additional 250 ml of sugary drink per day was associated with a 17% higher risk of coronary heart disease and a 4% higher mortality risk (all causes). It also showed that 25 grams of extra fructose per day was associated with a 22% greater chance of pancreatic cancer. Although not every link has been proven to be causal, evidence is growing that excessive sugar consumption can cause a lot of damage over time.
The conclusion of this review was clear: a diet rich in added sugars carries more health risks than benefits. Experts therefore advise limiting free sugars (including honey, syrup, and fruit juices) as much as possible. Ideally, intake remains under 25 grams per day, and drinking sweetened beverages is limited to one glass a week. In other words: use sugar occasionally — not structurally.
Sugar and chronic diseases: from diabetes to heart problems
Type 2 diabetes is one of the most pronounced consequences of long-term sugar intake. This condition arises from insulin resistance and persistently high blood glucose levels — often after years of overburdening the insulin system. A diet high in fast carbohydrates and sugars constantly pushes the pancreas to produce extra insulin, until that capacity is exhausted.
In addition, an excess of sugar contributes to a caloric surplus and weight gain, which in itself is a risk factor for diabetes. Epidemiological studies confirm that people who drink a lot of soda or sweet juices have a significantly higher chance of developing type 2 diabetes. In populations where sugar consumption decreased, the incidence of new cases also dropped.
Although other factors also play a role — such as a lack of exercise or nutritional deficiencies — sugar is a clear driver of metabolic dysregulation. It is often not the only problem, but it is one of the first links in the chain.
When it comes to cardiovascular diseases, sugar is also a factor that is increasingly being scrutinized. While for years the focus was on saturated fat and cholesterol, recent insights show that sugars also play a role in the development of high blood pressure, imbalances in blood lipids (such as elevated triglycerides), and weight gain — all risk factors for atherosclerosis and heart problems.
A well-known study from JAMA Internal Medicine with more than 45,000 participants showed that people who consumed more than 20% of their daily calories from added sugars had a significantly higher risk of dying from cardiovascular diseases than people who stayed under 10%. This risk persisted even after adjusting for other lifestyle factors.
Sugary drinks, in particular, prove problematic in this context. Several meta-analyses show a link between frequent soda consumption and a higher risk of heart attacks and strokes. The previously mentioned umbrella review calculated that every extra serving of soda per day increases the risk of coronary heart disease by 17%. On a population level, such differences can yield enormous health benefits through behavioral change.
Besides diabetes and cardiovascular diseases, sugar is also linked to other chronic conditions. Non-alcoholic fatty liver disease (NAFLD) is now common among young people with high sugar intake. This liver condition can progress to liver inflammation and fibrosis. In addition, chronic kidney diseases are linked to sugar — presumably through a combination of obesity, high blood pressure, and sugar-related damage to the kidneys.
Finally, various studies establish a link between a high-sugar diet and cancer. Often this concerns indirect effects via obesity, but there are also indications that sugar can play a role in tumor growth through elevated insulin levels. For example, pancreatic cancer has been observed more frequently in people with high fructose consumption according to observational research. Breast cancer and colon cancer are also mentioned, although the evidence there is less conclusive.
In the realm of brain health and mental well-being, the discoveries are equally alarming. High blood sugar can eventually damage blood vessels in the brain and is associated with cognitive decline. There is epidemiological evidence that people with a chronically high sugar intake score lower on cognitive tests later in life and potentially have an increased risk of dementia. Additionally, there seems to be a link between a high-sugar diet and depressive symptoms or anxiety disorders.
Possible explanations include blood sugar fluctuations (which cause mood swings), but also the fact that high-sugar foods can mask deficiencies in other nutrients that are actually important for brain function (such as B-vitamins, magnesium, zinc). Although not everything has been investigated to the bottom yet, these indications call for caution: too much sugar is not just a matter of tooth decay or gaining weight, it affects multiple organ systems and even our psychological health.
Conclusion of all this:
excessive sugar consumption saddles the body with constant fluctuations and stress (hormonal and inflammatory stress) that pave the way for chronic diseases. The good news is that reducing sugar intake can lead to improvements quite quickly. In some cases, effects are noticeable within a few weeks, such as more stable blood sugar, resulting in more consistent energy and fewer mood swings. Triglycerides in the blood also often drop when people stop snacking or drinking soda daily, and liver values improve when the fructose load goes down. For the long term, the benefits are even greater: a life with moderate sugar intake means a lower risk of the conditions mentioned above and a higher quality of life in old age.
Holistic strategies to break the sugar cycle
Given the potential harm of too much sugar, many people decide to reduce their sugar intake or even temporarily stop added sugars altogether (for example, through a “sugar detox” or a 30-day no-sugar challenge). But that is easier said than done – after all, sugar is addictively delicious and ubiquitous in our diet. A holistic approach can help break the sugar cycle. Holistic means looking at the whole picture: not just what you eat, but also how and why. It involves sustainable adjustments to your diet and lifestyle that support your body in weaning off those sugar crashes and spikes. Below are some strategies and tips, based on insights from nutrition experts and scientific studies:
-
Don’t cut out everything at once: If you notice you are “sugar-addicted”, eliminating all sugar cold turkey is often counterproductive. Suddenly trying to eat 100% sugar-free can trigger strong cravings and often leads to eventually giving in and perhaps even bingeing on sweets. Instead, gradually taper off. Allow yourself a small sweet treat occasionally, but try to reduce the frequency and portion sizes step by step. This makes cutting back mentally easier and prevents your body from going into protest mode. For severe sugar habits, you might first eliminate all soda and switch to water or tea, while still leaving a cookie with your coffee, and tackle that later. Realize: sustaining it is easier if you don’t deny yourself everything at once.
-
Eat whole, satiating foods: Replace sugary snacks with foods that keep you full for a long time. A pattern of three wholesome meals a day, rich in fiber, protein, and healthy fats, helps keep your blood sugar stable so you are less likely to crave sweets. Opt for whole grains, legumes, vegetables, fruit, nuts, and seeds, and sufficient protein-rich products (such as yogurt, quark, eggs, chicken, legumes, or tofu). This combination ensures slower digestion. “Steer yourself away from sugar and eat foods that digest more slowly. That keeps your blood sugar more even, so you don’t keep having spikes and crashes,” advises Dr. Michelle Hauser of Harvard Medical School. An example: start your morning with a bowl of oatmeal with fruit and nuts or an omelet with vegetables, instead of a sugary cereal or a sweetened croissant. Such a breakfast provides long-lasting energy and prevents you from crashing mid-morning and reaching for sweets. Drinking enough water and eating three main meals (so you’re not constantly hungry) are also part of this foundation.
-
Remove the temptation from your home: It sounds simple, but a highly effective measure is to no longer keep a stash of candy, cookies, and soda in the house. What isn’t available, you can’t thoughtlessly eat. Replace those stashes with healthier alternatives. Fruit is your best friend here – make sure there is always something deliciously sweet in the fruit bowl (bananas, apples, grapes, berries, etc.) for moments when you crave something sweet. A bowl of fresh strawberries or a few dates can wonderfully satisfy the need for a snack, with the added benefit of fiber and vitamins. If you still need a treat, try a small handful of unsalted nuts or a piece of dark chocolate (at least 70% cocoa) – these have a more intense flavor so you need less, and they provide antioxidants and magnesium at the same time.
-
Sweeten it yourself, if necessary: If you are used to sweet flavors, you can find a middle ground by sweetening your food and drinks yourself instead of buying pre-sweetened products. For example, choose plain yogurt instead of fruit yogurt with sugar, and add some fresh fruit or a teaspoon of honey yourself. Or drink tea/coffee without sugar, and if you need to get used to it, add a little bit of sugar or a drop of stevia if necessary – in any case, less than manufacturers usually do. Experience shows: no matter how much sweetener you add yourself, it will almost always be less than the amount of sugar manufacturers put in comparable products. This way, you stay in control and can gradually reduce the sugar dosage.

This way, you stay in control and can gradually reduce the sugar dosage.
-
Watch out for hidden sugars: Sugar hides in many products where you wouldn’t immediately expect it. Read labels carefully and learn to recognize the many aliases of sugar. Manufacturers use terms like high-fructose corn syrup, sucrose, dextrose, maltose, fruit concentrate, honey, agave syrup, etc. – ultimately, they are all sugars. Be extra alert with products carrying claims like “0% fat” or “light”; often, extra sugar is added to compensate and preserve the flavor. Don’t be fooled by “natural” sugars like honey or maple syrup – chemically speaking, they are no healthier than granulated sugar; they still contribute to your total sugar clock. Opt as much as possible for unprocessed foods or whole foods, then you’re generally on the safe side.
-
Don’t skip breakfast: Regularly eating breakfast can help prevent sugar cravings later in the day. Waking up with low blood sugar and then not eating can lead to ravenous cravings for quick energy (sugars) by lunchtime or even earlier. A balanced breakfast – for example, whole grains or bread, a portion of protein (egg, low-fat quark), and fruit – provides a feeling of satiety and keeps your blood sugar more stable until the next meal. Research shows that people who eat a good breakfast have less tendency to snack throughout the day, especially less craving for sweets. If you are in a rush or not very hungry in the morning, have something small but nutritious (a boiled egg, a smoothie with oatmeal and fruit, or a handful of nuts and yogurt).
-
Keep sleep and stress under control: Don’t forget that lifestyle is broader than just nutrition. Adequate sleep and good stress management are surprisingly important in the battle against sugar cravings. Too little sleep disrupts hormonal balance: the hunger hormone ghrelin rises and the satiety hormone leptin falls, making you hungrier the next day – often specifically for high-sugar, energy-dense foods. Sleep deprivation also increases activity in brain regions sensitive to reward, which makes the temptation of sweets greater. So aim for 7 to 8 hours of good sleep. Additionally, stress can lead to emotional eating and snacking. Chronic stress elevates the hormone cortisol, which prompts your body to want quick energy (sugars). Try to reduce stress with relaxation techniques (walking, yoga, breathing exercises) or hobbies, so you are less inclined to seek comfort in sweets.
-
Be patient and kind to yourself: Breaking a sugar addiction is a process of trial and error. It is normal to mess up occasionally and eat something sweet when you didn’t plan to. Don’t give up entirely right away, but learn from it and just get back on the healthy track at your next meal. Over time, you will notice your taste buds adapting – after a few weeks of eating little sugar, things like soda or cake will naturally taste MUCH sweeter than before. “When you get used to eating less sweet things, you also start craving them less,” says Dr. Hauser. You will then enjoy the natural sweetness of, say, a carrot or bell pepper more, which might have seemed bland before. This tipping point is pure gold: your need for sugar decreases and you no longer feel held hostage by that sweet tooth. Moreover, when you do have a real sweet treat on a rare occasion (a dessert at a birthday, a piece of cake at a party), you can enjoy it guilt-free because it has become a conscious exception and not a daily habit.

Living sugar-free: what it means, plus benefits and challenges
A term you hear a lot in health communities is “sugar-free living.” But what exactly does that mean? Eating completely 100% sugar-free is, in fact, impossible – and also undesirable. Healthy foods naturally contain sugars. Fruit is packed with fructose, milk contains lactose, and even vegetables and whole grains contain a bit of natural sugar. However, these products also provide essential nutrients (fiber, vitamins, minerals) and fit perfectly into a healthy diet. Moreover, our body makes no distinction between natural or added sugars once they circulate as glucose in the bloodstream.
When we talk about a sugar-free diet, we usually mean that someone eats no products with added sugar. You then avoid, for example, soda, candy, cookies, pastries, sweetened dairy drinks, sweet snacks, and sauces containing sugar. You do still eat fruit, vegetables, milk, etc., unless you follow an extremely strict regimen. Some diets that call themselves “sugar-free” go further and also restrict other carbohydrates (starchy foods), sometimes leaning towards a low-carb pattern. However, completely sugar-free in the literal sense would mean not even having fruit or milk anymore – and that is not healthy, because you would miss out on valuable nutrients.
In the Netherlands, there is no specific guideline saying “maximum this many grams of sugar,” but the Health Council does advise that for a healthy diet, about 40% of energy should come from carbohydrates. Carbohydrates include all sugars, starches, and dietary fiber. Diets that are very strict on sugars (and carbohydrates in general), such as some “sugar-free” or keto-like diets, often drop below that 40% energy from carbohydrates.
With that, you run the risk of deficiencies in certain nutrients, because you eat less fruit, whole grains, and legumes (with their vitamins, minerals, and fiber), for instance. In other words: living sugar-free should actually mean free of added sugars, not free of all types of sugar-containing foods. The most sustainable and healthy form is therefore to mainly eat according to an unprocessed, whole-food diet (which automatically means you consume very little added sugar), supplemented with an occasional small treat that does contain sugar, if you enjoy it.
Conclusion of all this:
excessive sugar consumption saddles the body with constant fluctuations and stress (hormonal and inflammatory stress) that pave the way for chronic diseases. The good news is that reducing sugar intake can lead to improvements quite quickly. In some cases, effects are noticeable within a few weeks, such as more stable blood sugar, resulting in more consistent energy and fewer mood swings.

Benefits of a (largely) sugar-free life:
These are noticeable for many people. First, more stable energy levels throughout the day – no more extreme sugar highs followed by sugar crashes. Your blood sugar remains within a narrower range, and you feel that in your concentration and mood; many people report fewer afternoon slumps and more consistent productivity. Second, it helps tremendously with weight management. Without all those “empty” sugar calories, you consume fewer calories overall, and the calories you do eat come from food that is more filling. Studies confirm that lowering sugar intake leads to weight loss in overweight people, even independent of other changes.
Belly fat also often decreases (this dangerous visceral fat is fed by sugar and fructose surpluses). Third, you reduce your risk of the aforementioned chronic conditions. Less sugar now means less chance of metabolic syndrome, type 2 diabetes, heart problems, and perhaps certain cancers in the long run. The immune system may function better with a more wholesome diet (although the direct effect of sugar on immunity mainly comes into play when you consume a large amount at once, temporarily slowing down immune cells). In addition, many people experience improvements in their skin (some notice less acne or a fresher complexion, as high sugar is linked to inflammatory processes that can also affect the skin).
A sugar-free diet, rich in vegetables and water, can contribute to better skin hydration and reduced sebum production. Furthermore, there is anecdotal evidence that sleep and mood improve – likely because blood sugar fluctuations at night can cause restlessness, and simply because you feel fitter when your diet is in order. Interestingly, some even cite benefits such as less joint pain and fewer headaches/migraines. While this doesn’t apply to everyone, for people with chronic inflammation (like arthritis), a reduction in sugar can contribute to less inflammatory activity and therefore less pain. All in all, the rule applies: by cutting added sugars, you make room for healthier foods, which benefits your entire body.
Challenges of sugar-free living:
What should you consider when making the switch? First of all, the withdrawal period. Especially in the first few days to weeks, you may experience strong cravings, and some experience genuine withdrawal symptoms like headaches, irritability, fatigue, or moodiness. Your body is used to quick sugar hits and now protests their absence. This is temporary – usually, after a week or two, these symptoms improve significantly if you persevere. Another challenge is the availability of sugar everywhere.
Grocery shopping requires more detective work (reading labels), and you will notice that you are better off avoiding certain aisles in the supermarket (soda/cookie/candy aisles). Socially, it can also be difficult: birthdays with cake, dinners where dessert is offered, or simply comments from friends and family (“One piece won’t hurt, right?”). It requires some assertiveness and planning to stick to your resolution without becoming anti-social. In social situations, you could perhaps suggest alternatives (bring your own sugar-free snacks, or opt for savory bites instead of sweet ones).
In addition, eating sugar-free requires cooking and preparation skills. Ready-made sauces, marinades, dressings, and meal kits are often full of sugar. You will make more things yourself: from pasta sauce to salad dressing. This takes some time and practice, but has the bonus that you are much more conscious about your nutrition. Some people miss the convenience or the reward of sweet snacks – a sugar-free diet can be perceived as boring at first. Here, it helps to look for creative recipes: for example, bake with bananas or dates as sweeteners, or treat yourself to luxury teas or herbs that naturally taste sweet (such as fennel tea or licorice tea) to curb your sweet cravings. Staying firm in company is also a challenge: sometimes you feel like the odd one out when you say no to cake. This requires a mental plan – for example, allowing yourself to have something small very occasionally on a special occasion so that it is sustainable, or eating beforehand so you are less hungry at the party.
Another point is that completely sugar-free often goes hand in hand with very low carbohydrates (especially if people also drop bread, pasta, etc.). This can lead to what is known as the “carb flu”: your body has to switch to fat burning, and in the meantime, you may feel weak or dizzy. It is not strictly necessary to ban complex carbohydrates when you go sugar-free – you can perfectly well continue to eat whole wheat bread, brown rice, potatoes, and the like. In fact, as mentioned, too few carbohydrates can be undesirable for your nutrient balance. So make sure that “sugar-free” does not degenerate into an extremely low-carb diet unless necessary for medical reasons. Eat plenty of vegetables, fruit, and whole grains, because they provide energy and keep your intestines healthy.
Finally, there is the challenge of long-term persistence. A strict sugar-free regimen can remain socially and emotionally difficult, so find a balance that works for you. Many experts recommend an 80/20 approach: eating sugar-free (or very low-sugar) 80% of the time, and allowing yourself a small treat 20% of the time. For example, a dessert on the weekend or something sweet one day a week. This can help mentally by feeling that you don’t have to miss out on anything “forever.” Many discover over time, by the way, that their cravings have greatly diminished and that even if they allow themselves something, they often notice that it actually tastes too sweet or isn’t really necessary anymore. Your taste evolves, and natural sweetness (from fruit, nuts, milk) often becomes sufficient.

Alternatives to sugar: stevia and xylitol examined
No longer adding sugar doesn’t mean you can never taste anything sweet again. There are several alternative sweeteners on the market that deliver the sweet taste without the disadvantages of regular sugar. We focus here on two popular choices often seen as “more natural” alternatives: stevia and xylitol. Both have been scientifically studied for safety and efficacy, but also have their points of attention.
Stevia (steviol glycosides):
Stevia comes from the plant Stevia rebaudiana, whose leaves naturally taste very sweet. The active compounds – steviol glycosides such as stevioside and rebaudioside A – are extracted and used as a sweetener. Stevia extract is 200-300 times as sweet as sugar but provides no calories and does not affect blood sugar levels, making it highly attractive to people with diabetes or those looking to lose weight. Because it contains no real sugar, no insulin is needed to process stevia. Research even suggests that stevia may have additional health benefits: some studies find that stevia has certain hypoglycemic properties, for instance, that it slightly stimulates insulin secretion and thus lowers blood sugar after a meal. This has mainly been seen in type 2 diabetics, although the effect is mild. Regardless, stevia does not cause sugar spikes, and that is its primary advantage.
Regarding safety, stevia has been approved by international and European authorities. The European Food Safety Authority (EFSA) has established an acceptable daily intake (ADI) of 4 mg per kilogram of body weight per day (expressed as steviol glycosides, in steviol equivalents). This means that a 70 kg person can safely consume about 280 mg of steviol glycosides per day – which equates to many teaspoons of sweetening power, given that stevia is so strong you only need tiny amounts. Within this limit, its use has been assessed as safe long-term: studies show that stevia is not carcinogenic or genotoxic and has no adverse effects on reproduction or development.
In practice, you won’t easily exceed the ADI unless you consume extremely large amounts of stevia products. To illustrate: the WHO calculated that an adult weighing ~89 kg can safely consume about 0.35 grams of pure stevia per day – which is more than enough to sweeten all your coffee, tea, and perhaps a baked good, because you often only need a few milligrams per cup (stevia often comes in powder form mixed with a filler, meaning a teaspoon of such a mix only contains a few mg of steviol glycoside).
Caveats regarding stevia:
Some people taste a slightly bitter or licorice-like aftertaste with stevia, especially in higher concentrations or when baking (heat can slightly alter the taste). This is subjective, and manufacturers are working on improved extracts (e.g., Reb M) that have less aftertaste. Another point is that pure stevia leaves or crude extracts were not permitted as food additives in some countries (like the US) (only the highly purified glycosides were allowed to be marketed as a supplement at the time). This was due to early animal studies that saw potential reproductive effects in rats at very high doses. However, these results are not directly relevant to human consumption in normal amounts, and later evaluations indicated that stevia poses no danger at the stated ADI.
Today, stevia is widely accepted in the EU and many other regions as a safe sweetener in all kinds of products. It may be that people with certain allergies or sensitivities have rare reactions (stevia is part of the composite family like ragweed, but allergy to it is very rare). Broadly speaking: stevia is an excellent alternative to sweeten something without calories and without affecting blood sugar. It is therefore widely used in diet sodas, sugar-free desserts, yogurts, and bars. Note: in products, stevia is often combined with other sweeteners (such as erythritol or maltodextrin) to add volume or balance the taste, so check the label if you specifically only wanted stevia. These combinations are also safe in themselves, but erythritol, for example, is a sugar alcohol that has been in the news (see more under xylitol/sweeteners).
Xylitol:
Xylitol belongs to the group of polyols (sugar alcohols). It occurs naturally in small amounts in certain fruits and vegetables and is industrially usually extracted from corn or wood (such as birch bark). In terms of sweetening power, xylitol is almost one-to-one with sugar (it tastes and looks like sugar, a grainy white powder), but it contains about 40% fewer calories (about 2.4 kcal/gram vs 4 kcal/gram for sugar). More importantly: xylitol has a low glycemic index (~7 compared to ~65 for sugar), which means it barely raises blood sugar. Your body cannot fully digest xylitol; a portion of it is excreted undigested or processed later through fermentation.
This makes xylitol attractive for people with diabetes or those following a keto/low-carb diet – you can figuratively bake cookies with it that are sweet but don’t drive up your blood glucose. Moreover, xylitol has a special bonus: it is tooth-friendly. Unlike sugar, oral bacteria cannot easily ferment xylitol, so it does not cause acid production that leads to cavities. In fact, xylitol has an inhibitory effect on the growth of Streptococcus mutans (a cavity-causing bacterium) and stimulates saliva flow. Studies show that regularly chewing xylitol-containing gum can significantly reduce the number of cavities. For this reason, xylitol is often added to sugar-free chewing gum, mouthwashes, and toothpastes – it sweetens the taste and protects the teeth.

Caveats regarding xylitol:
Although xylitol has many benefits, there are also health considerations. First, the gastrointestinal effects. Because xylitol is incompletely absorbed, it can draw water into the large intestine and lead to osmotic diarrhea and gas formation if you consume too much of it. Many people know the phenomenon of eating sugar-free candies and feeling abdominal pain or a laxative effect afterward – that is due to polyols like xylitol, sorbitol, or maltitol in them. Individual tolerance varies, but as a rough guideline, it is known that doses starting around 20-30 grams of xylitol at once can cause flatulence and loose stools in some people, and at 35-50 grams, this happens to most.
In a clinical trial, for example, a drink with 35 g of xylitol caused noticeable intestinal discomfort in almost all participants compared to a sugar drink. Fortunately, such amounts are quite large – a teaspoon of xylitol weighs ~4 grams, so as a sweetener in coffee (around 4g per cup), it stays well below that threshold. The problem mainly arises if people mindlessly eat a lot of sugar-free candies or chocolate; then it adds up quickly. The advice is to use xylitol (and other polyols) in moderation and to spread your intake throughout the day rather than consuming a lot at once. Often, your gut adapts slightly after some time, increasing tolerance. But sensitivity varies: some people already experience issues at 10 grams, while others can tolerate 30 grams without problems.
New findings on excessive Xylitol use
Too much xylitol in your diet can cause problems, recent research says (2024)
Too much xylitol in your diet can cause problems, recent research says (2024)
A second important point of attention recently made the news: potential negative effects of high xylitol consumption on heart health. Researchers from the Cleveland Clinic (led by Dr. Stanley Hazen) investigated in 2023 what happens to people who consume xylitol in amounts similar to those in some “sugar-free” foods. They observed that in healthy volunteers who received a drink with 30 grams of xylitol, their blood platelets were subsequently significantly more prone to clotting. In other words: xylitol in the blood made the platelets more “alert” to initiate clot formation, which could potentially contribute to an increased risk of heart attacks or strokes in the long term.
Related research also showed that people with naturally higher xylitol levels in their blood (some people endogenously produce slightly more polyols) showed a correlation with more cardiovascular events. This research is still in its infancy and does not prove that xylitol directly causes heart problems, but it does raise questions about the until-recently impeccable reputation of polyols as completely inert. Dr. Hazen indicates that more research is needed and calls for vigilance: we do not want people to massively replace sugars with something that might cause other harm. His preliminary advice is moderation: whether with real sugar or sugar substitutes, don’t overdo it.
Interestingly enough, he even states: “I would say that regular sugar or honey are actually better alternatives, even for people with diabetes, provided they are in small amounts”. The idea behind this is that people are so conscious of sugar/honey that they truly take a minimal amount of it, whereas with “sugar-free” candy, people tend to consume more under the guise that it is not real sugar anyway. In any case, the best option still seems to be satisfying the sweet craving with fruit – it also contains sugars, but in a package with fiber and nutrients, and it causes no abrupt spike. Fruit also satiates better and is difficult to eat in massive excess.
A third caveat, separate from human health but nevertheless important: xylitol is extremely toxic to dogs. If you have pets, be aware of this. In dogs, even a small dose of xylitol causes a dangerous insulin release that can lead to fatal hypoglycemia, and higher doses can cause acute liver failure. So keep products containing xylitol out of reach of four-legged friends and never share sugar-free chewing gum or baked goods containing xylitol with your dog. For humans, xylitol is safe, but for Fido, absolutely not!
Stevia or xylitol – which is better?
Stevia and xylitol are difficult to compare directly because they are very different in use. Stevia is calorie-free and has no effect on blood sugar, but its taste can take some getting used to and it is less suitable for replacing sugar 1-to-1 in baking recipes (because it lacks volume and has a slightly different flavor). Xylitol, on the other hand, has almost the same taste characteristics as sugar and is easy to use in recipes, but it does provide some calories (albeit fewer) and can cause stomach issues in excess. For a diabetes patient or someone on a low-carb diet, both are a blessing: no blood sugar fluctuations and still being able to enjoy sweetness. In fact, you can also combine them: some recipes use a little bit of stevia for intensity and some xylitol or erythritol for bulk; this way, you get a more sugar-like profile with few calories.
Regarding safety, stevia has the longest track record of being completely safe within reasonable intakes. Xylitol has also been considered safe for years (it is even endogenous – our metabolism produces a few grams of xylitol daily). However, the new findings regarding heart health and clotting are something to keep in mind. It does not mean you have to be afraid of a sugar-free candy now, but it does mean that “natural” is not always without nuance. As with everything, moderation is the keyword. Use these sweeteners as a tool to eat less regular sugar, but remain moderate with them as well. If you find yourself suddenly eating a lot more cookies “because they are made with xylitol and therefore okay,” it defeats the purpose. Calories can still add up (after all, xylitol has 2.4 kcal/gram), and the aforementioned potential risks come into play at high intakes.

Calories can still add up (after all, xylitol has 2.4 kcal/gram), and the aforementioned potential risks come into play at high intakes.
Finally, there are many other sweeteners (both natural and artificial) – from erythritol (another polyol) to aspartame, sucralose, saccharin, and new extracts like monk fruit (lo han guo). Each has its own profile. Aspartame and sucralose also contain no calories and no sugar, but are completely artificial; these are intensely sweet and have been used for decades. They have been extensively tested and generally deemed safe, although there are always debates about whether they, for example, influence the gut flora or maintain the habituation to sweet tastes.
For this blog, we limit ourselves to stevia and xylitol as examples, but if interested, it is worth delving into the pros and cons of other sweeteners. Some people, for example, prefer erythritol over xylitol because erythritol is less likely to cause intestinal complaints (it is already largely absorbed in the small intestine and excreted unchanged via urine) – however, erythritol was recently linked to a potential increased clotting tendency in a study, similar to the xylitol finding. This underscores that even zero-calorie options do not necessarily mean unlimited consumption.
In short: stevia and xylitol can be part of a sugar-free lifestyle as convenient substitutes. For example, use stevia to sweeten tea, yogurt, or homemade lemonade, and xylitol for occasional sugar-free baking or to have a few sugar-free mints. Both help you experience the sweet taste without the blood sugar spikes and crashes. But continue to listen to your body and use common sense. Ultimately, the goal is to train your taste buds so that you have less need for intense sweetness. Many people find that after living sugar-free for a while, their need for sweeteners also diminishes – a cup of herbal tea or a bowl of berries will then taste deliciously sweet on its own.
Conclusion
Excessive sugar consumption disrupts the natural balance in our body. It causes rapid insulin spikes and subsequent blood sugar drops, which lead to energy crashes and new cravings – a vicious cycle of sugar dependency. In the long term, it undermines our health: it contributes to obesity, insulin resistance, and an increased risk of chronic diseases such as type 2 diabetes, cardiovascular diseases, fatty liver disease, and possibly even mood disorders and cognitive decline. Refined sugars provide calories without nutrients and disrupt both metabolism and, in excess, the immune system and oral health.
Yet, there is a clear turning point: once we limit our sugar intake, the body can recover and normalize. Expert advice is clear – strive to drastically reduce your free sugars, ideally to at most about 5% of your daily calories (around 25 grams). In practice, this means: skip sugary sodas, opt for water, tea, or coffee without sugar; keep candy and pastries to a minimum or for special occasions; and be sparing with all those hidden sugars in sauces and meal kits. Replace empty sugars with wholesome foods that truly nourish you.
With a holistic approach – from food choices to sleep and stress management – it is possible to loosen sugar’s grip and reset your palate. Ensure regularity in meals, sufficient fiber and protein, and treat yourself to natural sweetness from fruit and spices. After the difficult initial phase, you will be rewarded with a clearer sense of energy, potential weight loss, and the knowledge that you are protecting your body in the long run.
And for those who still want something sweet occasionally: there are alternatives. Stevia offers sweetness without calories or blood sugar impact, and xylitol sweetens with fewer calories and tooth-friendly properties – use them wisely and in moderation as a tool on the path to a healthier diet. However, don’t forget the core principle: even though these sweeteners can replace sugar, the real victory lies in reducing your overall need for sweetness and enjoying the natural flavors in food. Ultimately, a lifestyle with little added sugar is a lifestyle of balance: where food serves as fuel and building material again, and not as a daily quick fix for energy drains.
By being mindful of sugar, you lay a foundation for better health. Small changes – like one less sugar cube in your coffee, or choosing water instead of cola – add up to massive gains. Science supports the importance of this change: a high sugar consumption is “in general more harmful than beneficial“, while cutting back brings tangible improvements. So give your body a break from sugar fluctuations and discover how sweet life can naturally be with the right nutrition and habits. Your future self will thank you for it!
