But Don’t We Need Protein? While we do need protein, perhaps we don’t need so much as we might think. The Center for Disease Control and Physician’s Committee for Responsible Medicine both agree we are getting plenty of protein and that protein deficiency
is not a problem in our society,
especially in comparison to the cancer problem we have.
The Physician’s Committee for Responsible Medicine (PCRM) even says that
we actually get too much protein, around double of what we really need. They advise using the Recommended Dietary Allowance (RDA) protein formula, which is : 0.8 grams per kilogram of body weight for the average adult.
To find out your average individual need, multiply your body weight in pounds by your recommended protein intake in grams.
