Vegetarian - Important
Non-Meat Sources Of Protein
Although most
vegetarians consume a considerable amount of protein, they
often do not absorb as much as they would on a nonvegetarian
diet. This is because plant proteins are considerably less
digestible than animal proteins, which contain amino acid
chains that are closer or identical to human amino acid
chains.
Consuming animal
proteins might yield close to a 1:1 absorption ratio, while
consuming plant proteins, such as wheat, might only yield 50%
of the amino acids needed to build a "complete protein"
or a protein that can readily be assimilated into the human
body.
In order
for vegetarians to absorb a healthy amount of protein, they must consume
a variety of plant proteins to form complete amino chains. By
eating vegetables, legumes, seeds, nuts, fruits,
and whole grains, vegetarians can increase the amount of
complete proteins they create by combining a number of
varieties of amino acid chains.
Vegetarians must also
consume more foods that contain proteins because plant
proteins are generally harder to digest. While a
nutritional label may suggest that pasta has 5 grams of
protein per serving; you may only be able to digest 2-3
grams of that protein, which means you must complement the
pasta with other sources of protein.
In
addition to natural sources of protein, vegetarians
should also
seek foods that are "protein-fortified"-- or artificially-infused
with protein.
For
example, many supermarkets offer a variety "protein-fortified" pasta and
bread. I have seen pasta that contains as much as 12
grams of protein per serving.
Soy milk
is also a good source of protein for vegetarians.
Studies on
isolated soy protein show that it can be absorbed nearly
as well as animal proteins, yielding close to a 1:1 protein
absorption ratio.
For
non-vegan vegetarians, yogurt, milk, and eggs (which contain complete
proteins) are all excellent sources of
protein.
As a
vegetarian you have a number of options to boost your protein intake -
and you should consider taking advantage of all of
them. You should diversify your food selections, drink
more soy products, and eat "protein-fortified" breads
and pasta.
