Animal products Protein-rich foods Plant foods Health foods Plant foods What type of nutrient is starch? Nutr. Although there is much evidence that excess fructose consumption has negative effects on health, it is difficult for researchers to separate the effects of fructose in the diet from those of other sugars. In foods, glucose is most commonly bound to another simple sugar to form either polysaccharide starches or disaccharides, such as sucrose and lactose (1). Another study found that while all added sugars can increase your risk of type 2 diabetes and obesity, high fructose corn syrup may be the most harmful (24). We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. (The prefix mono- means one.)
