The main purpose of this legislation is to improve the accuracy of nutrition labeling on food products. It aims to ensure that consumers receive reliable information about the nutrient content of the foods they purchase. By setting a specific standard for how much the actual nutrient values can deviate from what is stated on the label, the law seeks to protect consumers from misleading information. The key provision of this law states that if the actual nutrient content of a food item exceeds the value declared on its label by more than 5 percent, that food will be considered misbranded.
