Sugar substitutes are ingredients used to provide sweetness without the calories of regular sugar. They can be natural, like stevia and honey, or artificial, such as aspartame and sucralose. These substitutes are often much sweeter than sugar, so only small amounts are needed to achieve the desired taste. They are popular among people looking to reduce calorie intake or manage conditions like diabetes. Many sugar substitutes are marketed as healthier alternatives, but their effects on health can vary. Some may cause digestive issues or have other side effects, while others are considered safe for regular consumption. It's important to read labels and understand the ingredients in products containing sugar substitutes to make informed choices.
