what is protein?

Answer 1

Protein is one of the nutrients along with carbohydrate, fat, vitamins, minerals, and water. Some foods contain complete proteins and some incomplete protiens

Protein is an essential nutrient. There is no life withoutprotein.
Protein is contained in every part of your body, the skin, muscles, hair, blood, body organs, eyes, even fingernails and bone. Next to water, protein is the most plentiful substance in your body.

The amount of protein needed varies for different age groups, size and growth stage.

Even though an adult has achieved maximum growth, protein is required for maintaining body tissues.

Our body is able to produce 14 of the 20 amino acids. We have to get the remaining amino acids from the foods we eat.

Complete proteins contain all nine essential amino acids. Complete proteins are found in animal foods such as meat, fish, poultry, eggs, milk, and milk products such as yogurt and cheese. Soybeans are the only plant protein considered to be a complete protein.

Incomplete proteins lack one or more of the essential amino acids. Sources of incomplete protein include beans, peas, nuts, seeds, and grain. A small amount of incomplete protein is also found in vegetables.

Plant proteins can be combined to provide all of the essential amino acids and form a complete protein. Examples of combined, complete plant proteins are rice and beans, milk and wheat cereal, and corn and beans.

Try Wikipedia, though it is a bit tecnical.

Answer 2

Protein is one of the nutrients along with carbohydrate, fat, vitamins, minerals, and
water. The source of all of these nutrients is good. Some foods contain much higher amounts
of specific nutrients than others and sometimes we refer to certain foods as “protein foods.” It
is important to realize that all goods contain more than one nutrient and most foods contain
substantial amounts of several nutrients. For example, meat, which is a good source of
protein, carbohydrate, fat, riboflavin and calcium.
