Protein - Are Vegetarians Getting Enough? Are Meat Eaters Getting Too Much? Best Sources of Vegetarian and Non-Vegetarian Protein

Beans are an excellent vegetarian source of protein.

But Where do you Get Your Protein?

This is probably the most frequent and annoying question posted to vegetarians. It is a myth that a vegan and vegetarian diet is deficient in high quality protein. Vegetarians can easily get their daily requirements by eating a variety of foods high in plant proteins (see "Examples of Protein Content in Common Foods" listed below). Lacto-ovo vegetarians get additional protein from eating dairy and eggs.

How Much Protein do we Need?

The Recommended Daily Allowance (RDA) is 0.8 grams per kilogram, or 0.36 grams per pound, of adult body weight. According to this, a 130 pound female would need about 47 grams of protein per day. A 180 pound man would need about 65 grams. Since unprocessed plant proteins are slightly less digestible, the recommended protein intake for vegans whose diet is mostly from whole foods like grains, beans and vegetables, is 0.9 grams per kilogram, or 0.4 grams per pound. This uplift is not necessary if their diet includes tofu or meat substitutes which are highly digestible. Protein requirements increase during periods of growth and for pregnant and lactating women.

Can we get Too Much Protein?

The short answer to this question is yes. Eating too much protein causes a build up of ketones. This causes the kidneys to work extra hard to remove these toxic ketones putting undue strain on the kidneys. This also causes excess loss of water and calcium. Studies show that excess plant protein results in less kidney damage that excess protein from meat or milk.

As you can see from the list below, it is easy to consume excess protein if you are a meat eater. A few eggs in the morning, a cheese burger for lunch and a 6 ounce chicken breast for dinner would add up to over 100 grams of protein without even counting the protein obtained from the other grains or veggies eaten along with it. This is more than double the requirements for a 130 pound female. I shutter to think what the popular high protein Atkins diet has done to people's long term health. For a remarkable book that discloses the implications of a diet high in protein and fat, read "The China Study" by T. Colin Campbell and Thomas M. Campbell II. I believe it's one of the most important books ever written about nutrition and health.

A vegetarian or vegan who eats grains, tofu, nuts and beans can easily meet their daily requirements for protein. I do feel, however, that raw food vegans will have to make sure they are sprouting beans and grains and eating enough nuts and seeds to get sufficient protein.

Personally, I feel the healthiest diet consists of lots of raw fruits and vegetables, some cooked grains and beans, some goat yogurt and an occasional egg or fish dish.
