Guideline Daily Amounts (GDAs) have been approved by health professionals to help adults see how a food or meal fits into a healthy diet. When shopping you can compare the food's nutrient content to the following average values outlined below (and often found on food labels). For example, if you eat a meal containing 50g fat it is high in fat, and you would need to take care with the fat content of other foods you eat that day, to balance your fat intake out.
