Animal products and legumes are good protein sources. Like carbohydrates and proteins, fats supply energy to fuel the processes that keep your body alive. In contrast, however, they pack 9 calories per gram. They generally fall in one of four categories, based on their chemical structure: Trans fats are man-made and considered the unhealthiest because they raise bad LDL cholesterol and lower good HDL cholesterol.

Saturated fats usually come from animal fats and tend to raise bad cholesterol, while fish oil and vegetable fats are typically unsaturated and help lower bad cholesterol. Vitamins are complex organic substances that team up with proteins called enzymes, to help chemical reactions take place in the body. From reactions required for food absorption to bone building and reproduction, they are involved.

The Linus Pauling Institute describes 13 vitamins that the body requires for health and proper development. They vary in their specific roles and are either water-soluble, such as vitamin C and the B-complex vitamins, or fat-soluble, such as vitamins A, D, E or K.

Fruits and vegetables are among the richest sources of most vitamins. Minerals give structure to your bones, teeth and nails. Like vitamins, they assist enzymes in many body processes. Unlike vitamins, however, they are inorganic substances that come from the soil, rocks and water and are absorbed by plants. Major minerals often have recommended daily values above milligrams, according to the American Dietetic Association.

Examples include calcium, phosphorus and magnesium. In contrast, the body needs smaller amounts of trace minerals, usually less than 20 milligrams. They are packed as amino acids and used to perform a variety of bodily functions such as repairing cells, muscles, hair and tissues, as well as making hormones. The main sources of protein nutrients include: Carbohydrates are nutrients that provide the body with energy. Carbs are grouped into two main groups: The main sources of carbohydrates nutrients include grains such wheat, corn and oats as well as fruits, vegetables and roots.

Fats provide important insulation to body organs and help in the absorption of vitamins and minerals. Fats are divided into two primary groups: The main sources of fats are animals and plants. Vitamins are essential in maintaining the chemical balance in the body.
