Sugar provides calories and no other nutrients. Sugar or caloric sweeteners can lead to tooth decay.
Large amounts of sugar-containing foods, along with other carbohydrates and fats, can cause obesity in children and adults. Obese people are at much higher risk for type 2 diabetes, metabolic syndrome, and high blood pressure.
Sugar alcohols such as sorbitol, mannitol, and xylitol may have a laxative effect when eaten in large amounts.
