Nutrition facts labels tell you about the nutrition of a particular product. This information includes serving size, number of servings in the package, calories per serving and the amount of various nutrients contained in the product. Once you understand the labels, they can help you follow a healthy diet and make it easier to choose the most nutritious foods.
A study published in "Food Policy" in June 2010 found that nutrition labels do affect people's food choices. When you are deciding between two different foods, you can look at the nutrition labels to determine which food is more nutritious. You can compare the labels to determine which foods are lowest in calories, fat, saturated fat, trans fat, cholesterol, sodium and sugar. These are the ingredients you should limit for good health. Checking the ingredients list will help you avoid foods that contain additives or other ingredients that you want to avoid. The foods with the fewest ingredients and those that only contain ingredients that you would have in your own kitchen are healthier than those with lots of ingredients you don't recognize.
