If your dog doesn't consume
enough quality protein in his diet, he will synthesize 12 non-essential of the 22 amino acids by breaking down his own healthy muscle and organ tissues.
The only people who are really at risk for not
eating enough quality protein are those who are forced (or force themselves) to eat an extremely suboptimal diet with very few protein sources for long periods of time.
Get
enough quality protein in the daily diet - not only does it have a higher thermic effect than carbs and fat (so you burn more calories digesting it), but it also creates satiety so your hunger is satisfied longer.
For instance, if you're a starving African child who gets 80 or 90 percent of your calories from wheat or corn, you're probably not
getting enough quality protein.
It also must have
enough quality protein, in the form of amino acids... circulating throughout your bloodstream.
However, you also have to remember that eating
enough quality protein is vital for muscle repair, recovery, and immunity.
