Complete Protein and Protein Combining...
"The theory was initially promoted in Frances Moore Lappé's 1971 bestseller Diet for a Small Planet. The American National Research Council and the American Dietetic Association (ADA) soon picked it up, cautioning vegetarians to be sure to combine their proteins. Later, the ADA reversed itself in its 1988 position paper on vegetarianism. Suzanne Havala, the primary author of the paper, recalls the research process:
There was no basis for [protein combining] that I could see.... I began calling around and talking to people and asking them what the justification was for saying that you had to complement proteins, and there was none. And what I got instead was some interesting insight from people who were knowledgeable and actually felt that there was probably no need to complement proteins. So we went ahead and made that change in the paper. [Note: The paper was approved by peer review and by a delegation vote before becoming official.] And it was a couple of years after that that Vernon Young and Peter Pellet published their paper that became the definitive contemporary guide to protein metabolism in humans. And it also confirmed that complementing proteins at meals was totally unnecessary. Other nutrition experts and medical professionals who now agree that this theory is outdated include Dennis Gordon and Jeff Novick (registered dietitians), and John A. McDougall, Andrew Weil, and Charles Attwood (medical doctors)."
There is more and more evidence to suggest that the idea of protein combining is an obsolete concept. I have never worried about protein combining, the concept never made sense to me. It makes as much sense as saying that you need to have all your nutrients all in one meal, it just doesn't work that way. The human body is amazing, capable of adapting and doing incredible things. Eating a well balanced diet, with good sources of vitamins, minerals, fats, carbs and proteins is key. It's best to get natural sources for all of these things, of course for bodybuilding you should take protein shakes for adding muscle mass.
The thing to remember is that your body breaks down the proteins back to its basic elements, animo acids. Its the amino acids that form the proteins that the body uses.
There are a total of 20 amino acids found in our body:
•Alanine
•Asparagine
•Aspartic acid
•Arginine
•Cysteine
•Glutamine
•Glycine
•Glutamic acid
•Histidine
•Isoleucine
•Lysine
•Leucine
•Phenylalanine
•Methionine
•Serine
•Proline
•Tryptophan
•Threonine
•Tyrosine
•Valine
Amino acids are classified into two general types: essential and non-essential amino acids. Essential amino acids are those that can not be synthesized by the body on its own and thus need to be acquired through your diet. Non-essential amino acids are those that your body can produce, specifically by the liver, without any outside help.
Essential Amino Acid List
•isolucine
•Lucine
•Lysine
•Methionine
•Phenylalanine
•Thrionine
•Tryptophan
•Valine
•Histidine
•Tyrosine
Plant based sources of Essential Amino Acids
•isolucine: seeds and soya beans, egg, meat, fish, lentils, almonds and cashewnuts
•Lucine: lentils
•Lysine: potatoes, yeast, beans, soy products
•Methionine: lentils, beans, onion, garlic
•Phenylalanine: sesame seeds, tahini, nuts and beans, almonds, soya products
•Thrionine: brown rice, soy, peanuts
•Tryptophan: soy products, brown rice
•Valine: mushrooms, grains, peanuts, soya food
•Histidine : wheat, brown rice, rye
•Tyrosine: pumpkin seeds, oats, wheat, avocados, bananas, broccoli
Non-Essential Amino Acids
Your body can produce the other half of the twenty amino acids out of other chemicals that are present in your body.
Now there is ongoing debate on what is officially considered an "essential" amino acid. Regardless of what that outcome is the best practice is to eat a well balanced diet. A variety of fruits, vegetables and whole grains contain everything the body needs.
Some people would say this too difficult to do, having to worry about how they were going to get all their nutrients. I have never seen a animal based diet where you just had to eat one thing and that fullfilled your nutritional needs. While it's true that animal proteins contain all the amino acids, you cannot have a healthy diet without the plant based components. Soy, spirulina, hemp seed, amaranth, buckwheat, and quinoa are complete proteins
Some would say that it's not possible to get enough protein from plants, but if you think about it where do all those animals that people claim we need to eat for protein get theirs from?
Again, diet is like exercise, there's no quick and easy way. Everything worth doing and having requires hard work, compassion and research.
