Nutrition Information

On this web page and the next few pages I am going to provide some useful nutrition information and nutrition facts for healthy living style, as well as a revolutionary concept in weightloss - Matol Protein Diet Plan.

We need to constantly take in nutrients to build up our body structures, provide energy for our biological and physical activities, as well as to serve as essential elements for biological activities.

The nutrients that we need to maintain our health belong to the following groups: Proteins, Carbohydrate, Fats, Vitamins, Minerals, and Water.

I think we should also include Oxygen as a nutrient, since (1) we all know how important oxygen to us; and (2) we have ways to oxygenates the blood.

Nutrients and Functions

Proteins Facts

Protein is a large molecule composed of one or more polypeptides chains, each of which is in turn composed of amino acids. There are an estimated 100,000 different proteins in the human body, and each of them is made up of a different combination of only 20 amino acids.

The sequences and total number of the amino acids, as well as the number of each particular amino acid on the polypeptides chains are encoded in DNA. When mutations occur on DNA molecules, defective proteins or proteins with new functions might be produced, leading to diseases/dysfunction or even new varieties of the species.

Main Food Sources of Proteins: meats, eggs, cheese, milk, beans, grains, and some other plants seeds, like peanut, walnut, chestnut, etc.

Amino Acids:

Amino acids are the basic unit of proteins. Human proteins consist of up to 20 amino acids, 8 of which are essential amino acids because our human body can not synthesize them and they must be taken in from food. The rest amino acids are non-essential amino acids, since they can be synthesized by our body.

Essential Amino Acids: isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine. Essential only in children: arginine and histidine

Non-Essential Amino Acids: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, histidine, proline, serine and tyrosine.

Polypeptides:

Two or more amino acids are combined together to form a peptide chain. A peptide with fewer than about ten amino acids is called oligopeptide and a peptide with more than ten amino acids is called polypeptide.
