Eating enough to make you full for your daily food intake is not enough for optimum or even good health.
You must look carefully at what you are eating and make sure you get the recommended amounts of proteins, fats, carbs, vitamins and minerals in your diet. Doing so, along with at least a moderate amount of exercise 3-4 times a week will ensure good health.
Getting the recommended daily food intake for many different types of foods can usually be done by a balanced diet. However, there are occasions where you must supplement your daily food intake with a pill such as a multi-vitamin, mineral supplements or the like. This is perfectly fine, as long as you get the minimum recommended amount of each.
Most people follow the food pyramid to get what they need each day. The food pyramid is a list of the four basic food groups and the amount of servings you should consume each day from each group.
The biggest group is the bread, cereal, grain and pasta group. You should intake 6-11 servings from this group everyday. The next biggest is vegetables, from which you should consume 3-5 servings each day. After vegetables come fruits with 2-4 servings per day being recommended.
The milk, yogurt and cheese group (also known as dairy group) is after fruits and should have 2-3 servings ingested each day. Next is the protein group which consists of meat, poultry, eggs, beans and other legumes. You should try to get 2-3 servings each day for this. The very top of the pyramid is for things such as oils and fats, which have no recommended amount but should be used sparingly.
