If you are not diabetic and want to switch to a healthy sweetener, it is recommended that you first switch to natural alternatives to sugar such as brown sugar, honey and coconut sugar and then to sugar-free products, to ease the transition. If your goal is to lose weight, you can switch to sugar-free products. Sugar substitutes don't affect your blood sugar level. In fact, most artificial sweeteners are considered free foods.
Free foods contain fewer than 20 calories and 5 grams or less of carbohydrates, and are not counted as calories or carbohydrates in a case of diabetes. However, remember that other food ingredients that contain artificial sweeteners can still affect your blood sugar level. The FDA states that these sweeteners “are generally considered safe, meaning that they are safe to use for their intended purposes.”.
