As a nutrition expert, I am often asked about the differences between stevia extract and aspartame. While both are considered sweeteners, they have distinct characteristics that set them apart. Stevia is a natural, non-caloric sweetener, while aspartame is a nutritious sweetener that adds some calories but much less than sugar. Saccharin and sucralose are also commonly used as non-nutritive sweeteners with few or no calories. One of the main differences between stevia extract and aspartame is their taste.
Some people find stevia to be too sweet and persistent, while others don't notice any aftertaste. On the other hand, aspartame has a slightly bitter aftertaste that some people may find unpleasant. Sucralose, on the other hand, is often described as tasting more like sugar and lacks the bitter aftertaste. However, it may have a slightly chemical flavor for some individuals. But what makes stevia extract stand out is that it is derived from a leaf extract rather than tree sap, making it calorie-free.
It also has a low glycemic index and is rich in antioxidants, making it a popular choice for those looking to reduce their sugar intake. Stevia extract is often considered the best option for sweetening foods and drinks without adding calories or contributing to the intake of added sugars. It is safe for both children and adults to consume within the recommended daily dose, according to the FDA and JECFA. One of the main concerns about using low-calorie sweeteners like stevia extract is overuse and potential side effects. However, extensive research has shown that stevia extract does not increase the risk of dental caries or affect blood glucose levels. In fact, it is often recommended as an alternative to sugar for people with diabetes, as it does not raise blood glucose levels or affect blood glucose control. With a growing focus on reducing the consumption of added sugars, the use of low-calorie sweeteners has increased in recent years.
However, current intake levels are considered to be within acceptable limits. A model study even estimated the intake of stevia extract in children with type 1 diabetes and found that there is little chance of exceeding the acceptable daily intake. While some may question the impact of stevia extract on the gut microbiome, research has shown that it has a limited effect on the composition of intestinal bacteria. In fact, no randomized clinical trials have been conducted in humans to date, and there is no evidence that stevia extract significantly impacts the gut microbiome. As a nutrition expert, I believe that making small changes, such as replacing high-calorie, sugar-containing products with low-calorie sweetened options, can have a positive impact on overall health. However, it is important to also focus on other lifestyle factors such as healthy eating, regular exercise, and maintaining social support networks. Stevia extract has been used for food and medicinal purposes for centuries, and its leaves and raw extracts have been sold as dietary supplements.
However, whole stevia leaves and raw stevia leaf extracts are not approved as food additives due to a lack of toxicological information. While stevia extract is generally considered to have minimal effects on blood sugar levels, some more recent studies have questioned this idea. It has the potential to change the composition of intestinal bacteria and should be consumed in moderation. In conclusion, stevia extract and aspartame may both be considered sweeteners, but they have distinct characteristics that set them apart. Stevia extract is a natural, non-caloric option that is safe for both children and adults, while aspartame is a nutritious sweetener that adds some calories. Both can be used in moderation as part of a healthy lifestyle.
