Many sweeteners are promoted as healthy, natural, or low-calorie alternatives to sugar, but not all are completely safe. While they can provide sweetness without adding extra calories, some may affect metabolism, digestion, or even heart health if consumed in large amounts. Relying on these substitutes without moderation can lead to unwanted side effects, including blood sugar fluctuations or gastrointestinal discomfort. Being aware of the potential risks of various sweeteners helps you make informed choices for your diet. Opting for natural sources of sweetness, such as fruits, and using alternatives sparingly can support better overall health and wellbeing.
Health risks of popular sweeteners and sugar alternatives
A recent review published in Cardiovascular Research examines the potential cardiovascular risks associated with sugar alcohols, particularly erythritol and xylitol. While these sugar substitutes are commonly used in food products and pharmaceuticals, the review highlights concerns about their impact on cardiovascular health.
1. Raw cane sugar
Raw cane sugar is often promoted as a natural alternative to refined sugar. While it contains trace minerals, it is still primarily sucrose and impacts the body much like regular sugar. Excessive intake can contribute to weight gain, insulin resistance, type 2 diabetes, and heart problems. Even small amounts can spike blood sugar levels, and relying on it as a “healthy” sweetener may create a false sense of security. Moderation remains key, and whole foods like fruits are a better source of natural sweetness with added nutrients.
2. Saccharin
Saccharin is one of the earliest artificial sweeteners, found in diet beverages and sugar-free products. Although it contains no calories, it may alter gut bacteria, potentially affecting digestion and inflammation. Some individuals may experience bloating or mild digestive discomfort when consuming it frequently. Those with sensitive stomachs should limit intake, and long-term reliance on saccharin may not be ideal for overall metabolic health.
3. Aspartame
Aspartame is a widely used calorie-free sweetener in sugar-free drinks, yogurts, and snacks. While generally safe in moderation, it can affect appetite regulation in some individuals, sometimes leading to cravings for sugary foods. Rarely, people with phenylketonuria (PKU) must avoid it completely, as they cannot metabolise phenylalanine, a by-product of aspartame. Observational studies suggest overconsumption might subtly influence metabolic health, so moderation is recommended.
4. Erythritol
Erythritol is a sugar alcohol that tastes sweet with almost zero calories. While it is generally well tolerated, recent studies suggest high levels in the bloodstream could be linked to increased clotting risk, potentially affecting heart health. Consuming large amounts may also cause gastrointestinal discomfort, including bloating, gas, and diarrhoea. People with cardiovascular issues should be particularly mindful of their intake and combine erythritol with natural sweetening alternatives when possible.
5. Xylitol
Xylitol is another sugar alcohol often found in chewing gums, mints, and low-sugar baked goods. It has fewer calories than sugar and can even support dental health. However, excessive consumption can lead to gastrointestinal upset, including nausea, bloating, and diarrhoea. Pets, especially dogs, are extremely sensitive to xylitol and must be kept away from it entirely. For humans, small amounts are safe, but moderation is essential to avoid digestive issues.
6. Sucralose
Sucralose is a heat-stable sweetener commonly used in baked goods and beverages. While safe in moderate amounts, cooking or baking at high temperatures may produce chlorinated compounds, which could potentially have harmful effects over long-term exposure. Additionally, frequent sucralose consumption may negatively affect gut microbiota, impacting digestion and immunity. Rotating sweeteners and limiting processed foods can reduce potential risks.
7. “Natural” sugars (Agave, coconut sugar, honey)
Many people turn to agave, coconut sugar, or honey believing they are healthier than regular sugar. These options often contain additional vitamins or minerals, but they are still high in fructose or sucrose, which can spike blood sugar levels. Overconsumption may lead to weight gain, insulin resistance, and increased risk of metabolic disorders. While they can be used occasionally, relying on them as daily sweeteners is not recommended, and moderation is crucial.
8. Monk fruit blends (Often mixed with erythritol)
Monk fruit is naturally calorie-free and considered safe. However, most commercial blends combine it with erythritol to bulk the product. While monk fruit itself is generally safe, the erythritol component carries potential cardiovascular and digestive concerns if consumed in excess. People using these blends should monitor portion sizes and prioritise natural fruit-based sweetness when possible.
