Proteins and Amino Acids
What are Amino Acids?
Whether found in humans or in single-celled bacteria, proteins are composed of units of about 22 different amino acids, which, in turn, are composed of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur. To synthesize its life-essential proteins, each species needs given proportions of the 22 known amino acids.
Eight essential amino acids are needed to build tissue and maintain health in humans: leucine, isoleucine, lysine, methionine, phenylalanine, theonine, tryptophan, and valine. All of these are available in proteins produced in the seeds of plants, but because plant sources are often weak in lysine and tryptophan, nutrition experts advise supplementing the diet with animal protein from meat, eggs, and milk, which contain all the essential acids.
NutraAmino's delicious, fat-free, low-carb Ultra Pro Ultimate Protein Formula and
Ultra 1600 Weight Gain Formula are both great sources for
18 out of the 22 known amino acids.
There are two different types of protein. Complete Protein provides the proper balance of the eight essential amino acids (found in meat, eggs, seafood, milk, cheese, etc.)
Incomplete Protein lacks certain essential amino acids and is not used efficiently when taken by itself (this protein is typically found in seeds, nuts, grains and beans). Even though they are both made from the same 22 amino acids, the two types of protein differ in their function and work on different parts of the body.
People who are on a vegetarian diet or significantly reduce their intake of red meat, poultry or fish significantly reduce their intake of complete protein, which is essential for cell production, muscle and tissue building. If you are not sure whether or not you are getting enough protein through the foods you eat, then supplement your daily intake by having at least one healthy, nutritious, delicious! low-carb,
FAT FREE Ultra Pro Ultimate Protein Formula shake.
How much Protein do I need?
Everyone's protein needs differ depending on such factors as health, size and age. The larger and younger you are, the more protein you need. To estimate your daily protein requirement, use the following scale:
|
AGE: |
1-3 |
4-6 |
7-10 |
11-14 |
15-18 |
19
and over |
|
Pound Key: |
0.82 |
0.68 |
0.55 |
0.45 |
0.40 |
0.36 |
(Find the pound key under your age group. Multiply your pound key by your weight. The result will be your daily protein requirement in grams.)
Example: Male, 180 lbs., 33 years old.
Pound key: 0.36
Formula = 0.36 x 180 lbs. = 64.8 grams of protein per day
The average daily requirement is about 45 grams per day. That's more or less 15 grams of protein per meal, preferably taken during the day. (Why not try
NutraAmino's Ultra Pro Ultimate Protein Formula for lunch, or as part of a healthy nutritious breakfast?) Ultra Pro packs in an amazing 25 grams of protein in a single 8-oz. Serving, which is more than half of the average person's daily protein requirement!
