Talk:Protein combining

From Wikipedia, the free encyclopedia

Hey, I'm not an expert in nutrition, but I think this article may be a little biased. The idea of having to eat 2200 calories worth of brown rice - an entire day's worth of nutrition - seems a little off to me. What about the vitamins and minerals from other vegetables? And I think it's uphelpful to imply to vegetarians that they shouldn't worry about whether or not they're getting enough protein, or about which sources they are coming from. While it's true that animal protein is not specifically required in order to meet human dietary needs, science has clearly demonstrated the importance of the essential amino acids in the diet and the importance of a variety of different protein sources in the diet. And there are better examples to use - legumes and soy proteins springing immediately to mind, as they contain higher protein levels and a more complete set of amino acids.

I would agree that the estimates of 2200 kcal (ie 10 cups) are not a good comparison for amino acid intake. If a 73kg person’s only source of protein was rice they would need to eat 6 cups a day to receive the estimated full requirement of Methionine & Cystine according to this page. This is not realistic hence the concept of protein combining. ie 2 cups of rice and 1 cup of lentils would cover all essential aa and other foods for other nutrients. The concept that people need to specifically ensure they combine different plant proteins at the one meal is no longer considered necessary as aa that are lacking in one meal are usually consumed in another if a variety of pant foods high in protein consumed.Skeuu 00:49, 19 March 2007 (UTC)jeremy.
