While sugar substitutes may cause a decrease in blood sugar levels immediately after use compared to regular sugar, excessive consumption or long-term use can lead to insulin resistance and increase the risk of type 2 diabetes. Sugar substitutes can disrupt the balance of the gut microbiome.
Artificial and natural sweeteners are used instead of regular sugar for various reasons. Sugar substitutes can be beneficial for managing blood sugar levels and diabetes, but certain precautions should be taken when using them.
According to the 'Very Well Health' website, when used in moderation, sugar substitutes may be better for blood sugar levels than regular sugar (sucrose). Sugar substitutes contain fewer carbohydrates compared to regular sugar. For example, sucralose (Splenda) and some other artificial sweeteners contain less than one gram of carbohydrates per teaspoon. For comparison, a teaspoon of regular sugar contains four grams of simple carbohydrates.
In general, sugar substitutes are not digested in the same way as regular sugar. The simple carbohydrates in regular sugar are broken down into glucose, which is then absorbed into the bloodstream, raising blood sugar levels. Many sugar substitutes, including saccharin, aspartame, acesulfame potassium, and stevia, do not convert to glucose and therefore do not significantly affect blood sugar levels.
Compared to regular sugar, most sugar substitutes have a lower glycemic index. The glycemic index (GI) measures how quickly blood sugar levels rise after eating a particular food. Regular sugar is considered a high-GI food, with a score over 70.
Sugar substitutes are more than 100 times sweeter than regular sugar. Due to their intense sweetness, smaller amounts can be used compared to regular sugar. Using smaller amounts can help reduce total carbohydrate and calorie intake, which may benefit blood sugar levels. Sugar substitutes can also aid in weight loss efforts.
Many sugar substitutes contain fewer calories than regular sugar, so using them can help reduce overall calorie intake. Losing weight or maintaining a healthy weight improves insulin sensitivity, a key factor in regulating blood sugar levels.
Given the conflicting research results on the benefits of sugar substitutes, more studies are needed on their effect on blood sugar levels. While many studies show potential benefits, others have found that sugar substitutes only slightly improve or do not improve blood sugar levels at all compared to sugar. However, some sugar substitutes may be better than others.
You might wonder how to choose the best sweetener to control your blood sugar levels. It is advisable to consult a healthcare professional to help you manage high blood sugar or diabetes. As with regular sugar, sugar substitutes should be used in moderation due to potential side effects and other drawbacks. Excessive use of sugar substitutes can lead to diabetes. An imbalance in the gut microbiome can negatively affect insulin and blood sugar levels.
Recent research suggests a potential link between artificial sweeteners and heart disease. According to one observational study, high consumption of artificial sweeteners may increase the risk of heart disease.
Sugar substitutes can cause side effects, including gastrointestinal symptoms (stomach issues), changes in taste, allergic reactions, changes in insulin sensitivity, and effects on the cardiovascular system. Sugar alcohols have been linked to stomach upset, bloating, nausea, and diarrhea. Artificial sweeteners, in particular, have been linked to changes in the balance of bacteria in the gut microbiome.
