As you get older, good nutrition plays an increasingly important role in how well you age. As you age, you might need less energy. But you still need just as many of the nutrients in food.  Nutrients include proteins, carbohydrates, fats, vitamins, minerals and water. Studies show that a good diet in your later years reduces your risk of osteoporosis, high blood pressure, heart diseases and certain cancers. Eating a low-salt, low-fat diet with plenty of fruits, vegetables, and fibre can help reduce your age-related risks of heart disease, diabetes, stroke, osteoporosis, and other chronic diseases.  Balance your food intake with physical activity: the more active you are, the more food you need. Food provides the energy and nutrients you need to be healthy.
