The recommended guidelines for sugar intake suggest that added sugars should constitute less than 10% of total daily calories. For adults, this equates to about 200 to 300 calories or 50 to 75 grams of sugar daily. The American Heart Association recommends even lower limits, with about 6 teaspoons for women and 9 teaspoons for men. Excessive sugar intake is linked to various health issues, including obesity, type 2 diabetes, and heart disease. Therefore, it's vital to focus on whole foods and limit processed foods to maintain a healthy diet.
