Nutrition Law and Legal Definition

Nutrition refers to the science or study that deals with food and nourishment, especially in humans.

Guidelines, developed jointly by USDA and HHS, are the best, most up-to-date advice from nutrition scientists and are the basis of federal nutrition policy. The Food Guide Pyramid emphasizes foods from the five major food groups shown in the three lower sections of the Pyramid. Each of these food groups provides some, but not all, of the nutrients you need. Foods in one group can't replace those in another. No one food group is more important than another - for good health, you need them all.

The tip of the Pyramid shows fats, oils, and sweets. These are foods such as salad dressings and oils, cream, butter, margarine, sugars, soft drinks, candies, and sweet desserts. These foods provide calories and little else nutritionally. Most people should use them sparingly. On the second level of the Food Guide Pyramid are two groups of foods that come mostly from animals: milk, yogurt, cheese; and meat, poultry, fish, dry beans, eggs, and nuts. These foods are for protein, calcium, iron, and zinc. The third level includes foods that come from plants - vegetables and fruits. Most people need to eat more of these foods for the vitamins, minerals, and fiber they supply. At the base of the Food Guide Pyramid are breads, cereals, rice, and pasta - all foods from grains.
