Nutrition, nutrients, vitamins, minerals, amino acids, carbohydrates



Minerals are nutrients. They are necessary for the normal functioning of the body's cells. The body needs large quantities of sodium, potassium, calcium, magnesium, chloride, and phosphate. These minerals are called macrominerals.

The body needs small quantities of copper, fluoride, iodine, iron, selenium, and zinc. These minerals are called trace minerals, or microminerals.



Microminerals, or trace minerals, are nutrients. A micromineral (trace mineral) is required by the body in relatively small amounts (less than 100 mg day). Microminerals include chromium (Cr), copper (Cu), manganese (Mn), selenium (Se), sulphur (S), zinc (Zn).



Increasing Emphasis On Trace Minerals




Macro-minerals are nutrients. Minerals help the body perform numerous functions, such as building strong bones, transmitting nerve impulses, making hormones and maintaining a regular heartbeat.

Macro-minerals are the major minerals in animal nutrition (as distinct from trace minerals[micro-minerals]). Minerals are essential for body functioning and structure. They help to build body tissues (e.g. bone) or to regulate metabolic activities.

Dr. Linus Pauling, the only person in history who was awarded two unshared Nobel Prizes wrote this of minerals:

Fats (Lipids)


Fats or, more technically, lipids, are nutrients. Fats, together with carbohydrates and proteins, are one of the three staples of the diet. As the seventeenth-century nursery rhyme relates, ‘Jack Sprat he ate no fat/His wife she ate no lean’. This does not mean, however, that Jack Sprat could not get fat, because excess carbohydrates and proteins can be broken down in the body and the fragments synthesized into fat. But had he eaten no fat whatsoever he would have been deprived of certain essential fatty acids, and of the fat-soluble vitamins.



Carbohydrates are nutrients, along with proteins and other types of chemical compounds, but they are much more than that. In addition to sugars, of which there are many more varieties than ordinary sucrose, or table sugar, carbohydrates appear in the form of starches and cellulose. As such, they are the structural materials of which plants are made. Carbohydrates are produced by one of the most complex, vital, and amazing processes in the physical world: photosynthesis. Because they are an integral part of plant life, it is no wonder that carbohydrates are in most fruits and vegetables.
