Protein consists of chemical units called amino acids, of which there are many, but only 20 that synthesize protein in animal nutrition3 Day Refresh and Shakeology: Break Bad Habits. See Success..

These 10 must be obtained from food every day because the body cannot story excess amino acids in a rapidly available form, but it can break apart muscle protein to obtain any shortages. (Bodybuilders and athletes please note.) These 9 are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine and arginine. However, cysteine, taurine, tyrosine, and arginine are essential amino-acids in children because they are not able to synthesize these amino acids at an early age. In addition, arginine is essential for children but not adults.

Sources and Quality of Protein

Although just about all foods have some protein, the major sources are animal foods like meat, eggs and dairy, and plant foods such as nuts and beans and grains. Not only is it important for protein foods (or meals) to contain all the essential amino acids, but they need to be in ideal proportions to achieve an adequate growth and repair function in the human body. When the ideal protein specifications are met they are generally called “complete proteins.” Animal foods are complete proteins, but some vegetable sources are not.

The Protein Digestibility Corrected Amino Acid Score (PDCAAS) is a formal, preferred measure of protein quality developed and accepted by the US Food and Drug Administration and the World Health Organization. Here are some examples, 1.00 being the highest quality:

  • 1.00 – casein, milk
  • 1.00 – egg white
  • 1.00 – soy protein isolate, beans
  • 1.00 – whey protein isolate, milk
  • 0.92 – beef
  • 0.91 – soybeans
  • 0.78 – chickpeas
  • 0.76 – fruits

Types of Protein Powder Supplements

Depending on how you classify various products, protein powder supplements fall into four basic categories. However, there are many products and formulations, and some will suit more than one category. Most are reconstituted to make shakes, and some are provided as ready-to-drink shakes.
