Free sugar, also known as added sugar, is a type of sugar that is not naturally occurring in foods. Consuming too much free sugar can have negative health effects, such as weight gain and an increased risk for chronic diseases like diabetes and heart disease. To reduce the amount of free sugar in your diet, it's important to read food labels and choose products that are labeled "no added sugars" or "unsweetened." Other synonyms for free sugar include refined sugar, processed sugar, and artificial sweeteners. By reducing your intake of free sugar, you can improve your overall health and wellbeing.
