I'm pretty sure I know the answer to this, but thought I would check to be sure.<br><br>
A person I know is trying to eat a heap more veg food and a lot less meat. Someone has told them that they need to food combine to get complete proteins.<br><br>
I thought as long as you get enough of all the different proteins over a few days your body sorts it out.<br><br>
Am I right or wrong?<br><br>
Also sorry if this is in the wrong spot, but it is about food.

I think it used to be the case, that you had to combine foods with amono acids and foods with protein at the same meal. From what I've been reading/hearing lately, this is no longer the case, as long as the foods are combined throughout the day. I do not know if it is ok to do it over 'the course of a few days', however.

The foods we eat contain proteins which are broken down by our bodies into amino acids and then assembled into the actual proteins we need. It used to be the case that people thought they had to combine proteins in the same meal. However, our bodies are a lot smarter than that. We're fine as long as we eat proteins containing sufficient amounts of all the essential amino acids over the course of a day. (See e.g. <a href="http://www.veganhealth.org/articles/protein" target="_blank">http://www.veganhealth.org/articles/protein</a> )

The protein combining idea is a myth, the author that wrote the book that published this theory made a rebuttal years ago explaining that the previous publication was wrong. kinda sucks that so many people still believe this when it was so long ago and only standard for a short time, nutrition education is embarrassing .

The myth was that we had to combine proteins <i>in the same meal</i>. We should still eat foods with sufficient amounts of the essential amino acids, just not in the same meal necessarily.

yup, doesn't even have to be in the same day.

This I'm less sure about. According to the ADA:<br>
"<i>Research indicates that an assortment of plant foods eaten over the course of a day can provide all essential amino acids and ensure adequate nitrogen retention and use in healthy adults, thus complementary proteins do not need to be consumed at the same meal.</i>" (From quote on this page: <a href="http://www.veganhealth.org/articles/protein" target="_blank">http://www.veganhealth.org/articles/protein</a> )<br>
So at least we know "over the course of a day" is sufficient. Whether it can be longer I don't know.

Seeing as the person that created the theory about combining proteins (Frances Lappe) based it upon mimicking aminos in meat, which she later realized was wrong:<br><br>
""In 1971 I stressed protein complementarity because I assumed that the only way to get enough protein ... was to create a protein as usable by the body as animal protein. In combating the myth that meat is the only way to get high-quality protein, I reinforced another myth. I gave the impression that in order to get enough protein without meat, considerable care was needed in choosing foods. Actually, it is much easier than I thought."<br><br>
There isn't a scientific reason why we need to combine them at all, not even in the same day. Unfortunately bc this myth is still so prevalent the 'combine in a day' line is still out there as aftermath of the unfounded theory.

I believe there definitely is scientific reason and evidence to show that we do need to eat different foods (thereby "combining") to get all the different essential amino acids in reasonable amounts in order to maintain optimal health. This is not especially difficult though, and most people do this without much thought or even unknowingly when they eat a diet that consists of both legume-based foods (beans, lentils, chickpeas, peanuts, etc) in which the limiting amino acid is methionine AND grains/rice/pasta/bread in which the limiting amino acid is lysine.

its not really "combining" if you eat them at different times and on different days.

Yeah, it's pretty much just eating.

I disagree. People who don't know anything about nutrition or cooking, and maybe are picky eaters as well, are at risk of suboptimal health by not incorporating simple, yet important principles w.r.t. their food choices. (Edit: My point is that we do actually make some choices (either consciously or by habit) with the aim of allowing different amino acids to combine.)

i doubt it, people that don't know much about cooking or nutrition eat what they feel like eating regardless of amino acids. i don't even think about it and achieve to get all my bases covered just by eating a varied diet.<br><br>
basically you can know nothing about aminos and still manage to get them by eating a small variety of foods ( you really dont even need to eat a big variety, just a few foods are enough from what studies have shown).<br><br>
the whole incomplete/complete protein thing bothers me mostly bc the author admitted to creating the theory under the belief that meat was the ideal protein and to show that a plant based diet can give the same nutrition as meat can.

Misty, I'd follow the link that IS provided. Luvourmother's characterization of protein combining being a "myth" is over-reactive; the combining is a matter of chemistry within your body and nutritionists have generally agreed in the last many years that it can take place as long as the essential components are ingested within a few days of each other.<br><br>
Of course, this forum isn't the best final authority on nutritional advice, so check your facts to your satisfaction.

Another note: if you are concerned that a vegan advocacy site might slant their presentation on nutrition (a fair consideration when you don't know them), I suggest you look into the work of Marion Nestle. She's one of the most noted nutritionists in the world and as I recall she wrote on this very issue in her "Food Politics" book and has been fairly outspoken on the subject elsewhere. She is not vegetarian herself (last I checked) but advocates combining vegetable proteins over several days.

Thanks, paperhanger. Just wanted to add that usually the only important food choice we need to consciously make w.r.t. protein is to include legumes (bean, lentils, chickpeas, peanuts, etc) since the we tend to get enough of the amino acids found in other foods anyway.<br><br>
Some people think that they don't like legumes (maybe because they've never tried that many types). Others instinctively choose to eat them, maybe because they believe in the virtues of a varied diet or because they cook from recipes that have them.

Yeah, it's fascinating how many traditional food combinations have a bean and grain combination built in. Corn and beans in latin cuisines immediately springs to mind, but other cuisines have developed dishes along similar lines. Now if I could only figure out why anyone thought nixmatilization was a good idea. Folks in Mexico/Latin America wouldn't have survived for long without it, but it doesn't seem intuitive at all. (Nixmatilization = treating corn with something alkaline, creating masa, which is much more nutritious )

Many Modern Maya claim that the only reason they put lime in the soaking water for dried corn is because it softens the outer hull and makes it more easily grindable. Knowledge of nixtamalization as isn't even considered. My theory is that sometime(s) in prehistory it was discovered that corn soaked in a limestone vessel yielded more grindable corn than when soaking in a ceramic or wood vessel. Limestone was added ritually/habitually as a result, and the benefits were observed though never explained.
