These nutrient classes can be classified as obese - the nutrients (in relatively large quantities required), or nutrition (small amount) needed. The macro nutrients carbohydrates, fats, fiber, protein and water are. The vitamin and mineral nutrition are.

The macro nutrients except that the fiber and water is measured in Joules or calories, energy, provided (often "calories" and called the village with a capital C, to distinguish them from written calories). Supply of carbohydrates and protein per gram of 17 J energy (4 kcal), fat, while 37 KJ per gram (9 kcal) supplied. vitamins, minerals, fiber, water and energy, but for other reasons are required.

Carbohydrates and fat molecules of carbon, hydrogen and oxygen atoms are. Carbohydrates (glucose, fructose, galactose) simple monosaccharides complex polysaccharides (starch) from the range. Fat triglycerides of different fatty acid glycerol monomers are bound to. Some fatty acids, but not in the diet are necessary: they can not be synthesized in the body is. Proteins, carbohydrates and fat molecules in addition to the elements are nitrogen atoms. The nitrogen - protein amino acid monomers are included, and a number of essential amino acids are. He says, and many other roles in addition to energy metabolism work when they are used as fuel, the nitrogen to reduce the burden on the locations of the kidney.

Antioxidants and other phytochemicals include nutrition.

Some or all of the food categories are a mix of nutrients. Some nutrients regularly, others are required only occasionally. Imbalance of nutrients of poor health, or a deficit caused by too much can be done.
