Answer with Explanation:
Reading and understanding nutritional labels give a person an in-depth information on what food he is buying, whether it's suitable for his diet or not, and its nutritional content. For example, if he is on a diet, the nutritional label will tell him how much calories a serving of a particular food is. It will also let him know whether the food is high in fats, sodium, protein and the like and this means he can be mindful in choosing his food. If he is a Muslim, it will let him know which of the foods are "halal certified."
