Getting a Complete protein?
Hello -
Can anyone offer advice in terms of getting a complete protein with raw food? I snack on nuts, but is there anything else raw that can be combined with these to get a complete protein? Beans and peas are not so great raw. I'm looking for a raw supplement to nuts that can give me a complete protein. Also, how much of it do you really need to eat to get the 55 grams a day of protein your body needs? Thanks. RB |

Each nut and seed has an unique amino acid profile. Pistachios are nearly "optimal," whereas many other nuts and seeds are low in lysine. Macadamias, for example, are very very low in lysine. > Beans and peas are not > so great raw. Mung bean sprouts are probably the easiest legumes to eat raw.

That's probably a better combination of aminos than the typical omnivorous diet. This combination also provides 255% of the daily value for vitamin A, 841% for vitamin C, 60% for vitamin D, 83% for vitamin E, 113% for thiamin, 172% for riboflavin 108% for niacin 163% for b6, 499% for folate 98% for pantothenic acid 3081% for vitamin K, 162% for calcium 114% for iron 188% for magnesium, 144% for phosphorus 144% for potassium, 65% for zinc, 296% for copper, 405% for manganese, and 1223% for selenium, with an omega6mega3 fatty acid ratio of about 3:1 and 1125 kcal. You could also get about the same amount of protein with an amino score of 96 and a 1370 kcal with 2 cups of raw pistachios. But, I am not sure if raw pistachios are truly raw. |

I see "raw" pistachios in the stores, and they do tend to swell up well if soaked. I'm not sure if they are still able to sprout though, they get eaten before that. Lysine is less of an issue in raw diets because it is made less available by cooking. Here is my message on this topic. John One of the prevailing myths of meat eating is again enjoying the rounds amongst the alternative diet community. This is the "quality protein" idea, whereby it is claimed that only animal proteins are "complete". These myths seem to pass around in cycles because various outlets for dietary information do not enforce any scientific credibility for the claims they make. Specifically, such articles or claims do not provide any references or credible background. In this article I provide references and numbers so that anyone can check the validity of my claims for themselves. The basis of the complete or ideal amino acid balance was originally an animal experiment based on rats in which various proteins were fed to weaning rats in order to observe which one produced the most rapid growth, and was therefore considered "ideal". At the time egg was considered the reference protein, because it produced the fastest growth. Obviously such experiments say nothing about optimal human diet, or even what the ideal source of protein is for humans. So what are the facts? In 1997 I researched an article called "Protein - Bionomic Nutrition", and read up on the latest protein research. The findings of the research are as valid now as they were then. They involved experiments using labelled amino acids. Protein is made from a variety of amino acids, and it is the ratios of these that determine if a protein can support human growth, and maintenance of lean body mass. When certain kinds of a few foods are eaten as "staples", amino acid malnutrition can occur, because the protein is not "complete". Only a few typical foods do not provide a quality source of protein and are problematic if eaten as significant staples. How were the standards set up? Labelled amino acids can be closely monitored by researchers to determine how they are used by the body. Before this technique evolved we also have population studies, and nitrogen balance studies that examined how well children grow and develop on different diets, and how the protein source affects growth and mantennance. In total, the available evidence is conclusive beyond any reasonable doubt and is published by such bodies as the World Health Organisation. Although the methods vary, and the new techniques suggest that some amino acid requirements may be higher than traditionally thought, in effect things have not changed much over decades and the whole topic is fairly un-contraversial amongst the scientists in the field. Anyone who talks of a need to eat animal products to obtain a "complete protein" or a "quality protein" is simply talking bunk, and you will not hear such claims from anyone with even a basic modern academic background in nutrition. The table below identifies both the old, but still valid requirements published by the FAO/WHO and UNU in 1985, and some possible new suggestions by later researchers. As you can see beans, rice and even potatoes all provide acceptable protein, in fact they are abundant sources of essential amino acids. I have also averaged the essential amino acid contents of various other food groups, and ALL provide a source of "quality" protein on average. Unless one eats a diet made up predominantly of a few certain kinds of food, one will almost certainly allways get proteins of "good quality". The numbers prove this.

(1989). Geoffrey Cannon, author of Food and Health: The Experts Agree, from the Consumers' Association, also says that fruits yield "quality" protein. Fruits also provide a quality source of protein, although they may not contain enough protein in total to meet daily requirements even when large amounts are consumed. Addings some seeds to the diet easily corrects for this. Fruits providing a balanced protein source include avocado, banana, figs, orange, persimmon, pineapple, watermelon, and others. Why does the protein myth refuse to go away? My conclusion - people want some pseudo scientific reason to justify their meat eating.

My conclusion - people want > some pseudo scientific reason to justify their meat eating. I do not think this is the true motivation, although it may have been a motivator for Vernon Young, who died of renal cancer at 66 after two previous triple bypass surgeries. The tracer studies with 13C-labeled amino acids have been used to refine minimum physiological needs for selected indispensable amino acids in healthy adults, and the US DRIs quickly adapted something similar, although there remains some controversy. The new suggested requirements for adults from the MIT study are more difficult to meet on some odd or careless sects of veganism, such as strict fruitarianism or junk food veganism. From http://www.nutrition.org/cgi/content/full/130/7/1841S table 7. suggested adult requirements mg/kg/day lysine 19 aromatic 20 (phenylalanine, tyrosine) sulfur 16 (cystine, methionine) valine 14 leucine 26 isoleucine 18 threonine 16 tryptophan 4 I crunched some numbers for a strict fruitarian diet (1 cup each of apples, bananas, blackberries, grapefruit, jackfruit, grapes, mango, canteloupe, nectarines, oranges, peaches, pineapple, plums, raspberries, strawberries, and watermelon) and found there were deficiencies in lysine, aromatics, cystine, methionine, valine, leucine, isoleucine, threonine, and tryptophan. But, these deficiencies were eliminated by modest substitution of some of the sweet fruit wth leaves, sprouted legumes, and seeds. |

Thank you, both, for your informative replies.
Wanted to ask, are peanuts fair game for "legume" protein? Everyone talks of combining "legumes" with "nuts/seeds" ... what about combining pistachios/almonds with peanuts for a complete protein? |

No, raw peanuts contain trypsin inhibitors (all legumes have these, and they can be partially deactivated by sprouting) and traces of aflavotoxin and you should not eat them more than sparingly, if at all. > Everyone > talks of combining "legumes" with "nuts/seeds" ... The "talk" is that it isn't necessary for sensible diets. >what about > combining pistachios/almonds with peanuts for a complete protein? You don't need to combine to get a "complete" protein. All foods contain the required aminos, but the individual EAAs might be more or less abundant than a so-called "optimal" level in any particular food. This includes ground beef, which is woefully inadequate in tryptophan. There is a pool of aminos in your body, and it doesn't matter much from meal to meal or over a few days or more if you are short on one or another. The problem might happen if you came up short consistently for a long period of time. This is highly unusual in Westerners unless they are doing something really strange with their diets, like strict fruitarians or even worse, mono-eating strict fruitarians. People do strange things.

Where is the data for supporting this? The only gold sandard for valid health research deductions is long term studies in which the subjects were actually healthy. Anything else is superstition. It amuses me that ordinary citizens are often described as "healthy" in medical papers because they have no diagnosed medical complaints. Yet even so, these kind of people may have regular colds, headaches, constipation and such and are simply not healthy. > The tracer studies with 13C-labeled amino acids have been > used to refine minimum physiological needs for selected > indispensable amino acids in healthy adults, and the US > DRIs quickly adapted something similar, although there > remains some controversy.

Yes, one detrimental effect of hybridisation is the systematic reduction of seed matter in our fruits. I only started eating more seeds as part of my raw diet a couple of years ago. Before that it was mostly fruit and some salad. I can't say I've noticed any difference throughout, and I've never had obvious evidence of a deficiency. What would an amino acid deficiency look like anyway? Eventually I think you would lose muscle. I have heard of this in fruitarians, and raw foodists who don't eat enough. Including some seeds in the raw diet seems prudent. Sprouted puy lentils in one of my favourites, as are pumpin and sunflower seeds. Mixing sprouted seed milks (eg hemp) into a smoothie is also very enjoyable. John |

People do strange things. Laurie told me about some raw foodists who were strict fruitarians back in the 70s.

Obvious malnutrition, but he couldn't tell him to change. As most Westerners over consume protein, these new figures are not very useful for us. John |

The next four paragraphs are from K. Milton's "Nutritional Characteristics of Wild Primate Diets," Nutrition 1999 15:6-- "For various reasons, it is generally the case that plant protein has a lower biological value and digestibility than protein from animal foods (1). Meat protein, which is essentially identical in its protein composition to human protein, can be deposited with virtually no modification and is generally about 98% digestible (1). In contrast, vegetable foods show a protein digestibility in humans averaging 90% (1). "One reason for the lower digestibility of plant protein could be secondary compounds (tannnins, phenolics, alkaloids, terpenoids, etc.)(2-5). Some bind with protein in the gut rendering it unavailable to the feeder (5,6)." "Because of the many secondary compounds in their foods, wild primates may need to consume more grams of protein per day than would be predicted by body weight (7). Assimilation studies suggest that some 20% or more of total N in wild plant parts is unavailable to the feeder (7). Thus, for example, a 7-9 kg wild howler monkey might have to take in some 20 or more g of protein each d in its wild foods to net the 12 g or so of protein it is estimated to require. (7). "Though animal protein may generally be of higher quality and more digestible, plant protein appears to suffice for many monkey and ape species" (1) Carpenter KJ.

Those are rather sweeping statements. Firstly humans do not climb up and down trees all day, wild primates are more like human body builders in what they do, and no doubt their protein requirements are higher.

It is the lowest protein milk of all the primates.

For a herbivore to consume animal protein does not make the animal better in some way does it? So what is inherently better about animal protein? Does this misnomer simply mean it is 10% more digestable?

Yes, but how do you *really* do this? Coming from a meat/dairy
inclusive diet, it seems quite difficult to switch to a vegan mode and "get everything you need" in a day. I dig the oatmeal + fruit breakfast, and then around lunch, a bowl of mung beans and some lentil or bean soup with some nuts, which is "passable". Then for dinner -- what, more soup and a potato? And this is just *one day.* Turkey and/or cheese sandwich is heavily missed. I believe that this diet is "reality" when it comes to the way we're supposed to eat, perhaps with a little meat here and there, but by and large it seems like a very difficult transition. I still don't feel like I'm getting enough protein, and my head seems to be telling me that pretty chronically. I don't do much bread, as most of it is refined paste and doesn't really "travel too well" bodily. I feel like I'm missing "substance" to a meal without a sandwich or a piece of meat. |

Modern cultivated fruits do not resemble the wild fruits that our primate ancestors ate, nor do they resemble the wild fruits that our wild primate cousins eat. Wild fruits are higher in protein, EFAs, soluble fibers including pectins, and richer in vitamins and minerals as well. If one wanted to approximate the nutrient intake profile of the wild primate (or even paleoman) with modern cultivars, it would require more than minimal use of leaves and other vegetables, nuts, and seeds, at the expense of cultivated fruit. > This would not apply to fruits.

I looked at an average of 80 fruits and the results were worse, but this included a number of nearly-all sugar and fat fruits. If you prefer to specify the fruits you are most interested in, I can do that for you. I think that the analysis would be most valuable for common, easily obtained fruits. > I wonder how digestability compares? This is academic though, if you add > some seeds to the diet, you will make up for the losses from cultivation. It isn't only seeds. You also do well with a number of leaves. Seeds are not particularly nutrient-dense and they are not the greatest sources of many vitamins and minerals.

Leaf-eating is very natural. Our modern cultivated leaf foods are probably a better match for wild fruits than cultivated fruits, from the nutritional standpoint. Composites (lettuces) have very little oxalate. The crucifers vary--there is hardly any in turnip greens and moderate quantities in collard greens. It's the goosefoot family and some members of the parsley family that are high in oxalates, but goosefoots are so great for vitamin E and protein, and other vitamins, that it would be a shame to omit them. They are fine in moderation, especially in a background rich in a wide variety of other plant foods. >>Yes, it is not such a big deal. It's a term they use to broadly >>represent assimibility.

Neither did Paleoman. Primates that spend any time in trees burn up loads of calories and turn over a lot of protein. Many primates have far more muscle bulk in proportion to what humans have - they turn over more protein just moving around. I consider it a safe bet they need more protein than we do, and that may explain why humans have the lowest protein milk of them all. > > Sure, cultivated fruits have had their seeds mostly bred out. > > It isn't only seeds that are different.

I was counting legumes and grains as seeds. I find the shop fungi rather bland. We had a huge mushroom in the yard this year, which I dehydrated to make into a "mushroom pizza" - I topped it with a spread of avocado and some dried and fresh tomatoes. I never tasted a shroom as good as that, really a very full flavour. > Not at all. Leaf-eating is very natural. Our modern cultivated > leaf foods are probably a better match for wild fruits than > cultivated fruits, from the nutritional standpoint. I think there may be some truth in that yes. However, we have had to cultivate them, which isn't very natural, and we don't have very good teeth or guts for dealing with real leaf matter. However, when I was in Malaysia I was offered a common weed that is eaten there, and it was not bitter in its raw state. There was also this weird melon like fruit that grows everywhere like a weed. I never tasted that though. Some of these wild fruits are in fact very green on the skin and juicy rather like leaves. It all reminds me that we cannot accurately summarise the variety of plant matter out there. > Composites (lettuces) have very little oxalate.

Thanks, I don't think we get all of them here though. > She states that plant protein is adequate and that flesh eating is > not necessary for meeting protein needs. Do you disagree? That at least is correct - in fact meat just isn't necessary for but a few mammals. I think Goodhall says that chimps don't need meat to grow normally. There are about 13 primates listed in one of my books that are not noted to eat any animal matter. > I like her earlier work. I am not so crazy about the latest paper, > though. Join the critics http://www.ecologos.org/meat-eating.htm. Everyone has to pay the bills. > 0.45 g/kg, type unspecified, is inadequate for the elderly human > female. PMID: 7598064 Interesting. Harpers Biochemistry claims 30g/d is enough for the average male - this is a physiolgical requirement, not dietary advice BTW. Elderly people digest animal proteins poorly and are often in poor health, so this may make results non-generalisable if this is the case. The study needed an additional group of subjects reflecting a broader range of the normal population to make results generalisable. Increased carbohydrate intake can also spare protein, so that needs to be measured as well. Did you read the paper, what "protein" did they feed them? regards, John |

But, there is a very high calorie cost associated with what they offer. They are not high on the nutrient density list.

The 18:n2 to 18:n3 ratio is higher or much higher than the recommended 4:1 or lower, for almost all seeds proper with only a few exceptions: flax, hemp, pumpkin. That doesn't mean they should be elminated, only that the emphasis should probably be on the higher 18:n3 ones. Even when they are all raw. Both 18:n2 and 18:n3 are highly oxidizable, 18:n3 even more so than 18:n2. > We cannot accurately summarise the variety of plant matter out there.

I think perhaps she might have responded more positively to praise and some minor questions, rather than a full-blown assault. She has in the past seemed to be very symptathetic to veg*nism, especially in her replies to that infamous Cordain paper. But I agree, she could do a lot better with more soluble plant fibers in her diet and a lower BMI + some exercise. >>0.45 g/kg, type unspecified, is inadequate for the elderly human >>female.

(1996) and they even tell you how to calculate physiological requirements. The figures are as follows: %protein average (non obese population) male 17.5 daily turnover = 1-2% (the less you exercise the lower the figure as muscle contributes most turnover) recycling efficiency = 75-80% (here I believe exercise may increase efficiency, but not much) thus:- for 65kg male, total protein = 11375g turnover = 113.75 - 227.5g unrecycled = 22.85 - 56.9g Their figure, as you can see, is closer to the low side, as will be appropriate for most of a sedentary population.

Thank you all for sharing that. I'm finding it still difficult to
maintain the "quantity" level necessary. Thinking in terms of 10's of cups is much different than thinking in terms of a small bit of meat or dairy. Maybe this is not true, but it seems you really have to consume a LOT more vegetables than you do dairy/meat, in terms of what seems to be the density of protein in the foods.

If you do eat lots of greens, you will reap multiple benefits with an exceptional level of vitamins, minerals, soluble fibers, and protective phytochemicals which may drastically reduce your risks for CHD, most types of cancers, diverticulitis, stroke, etc. The healthiest diets, whether omnivorous, vegetarian, or vegan, incorporate lots of greens, and it is a good thing to do regardless of protein content or goals. > Maybe this is not true, but it seems you really have to > consume a LOT more vegetables than you do dairy/meat, in terms of what > seems to be the density of protein in the foods. This is true for leaves, but less so for non-leafy vegetables, and untrue for many legumes, seeds, and plant protein isolates. One tablespoon (15 g) of Nutribiotic rice protein powder provides 12 g of protein with 58 kcal. |

**Maybe a topic should be started with some critical, actual facts on
protein and calcium. Here's something I picked up at a seminar last week** Humans only need about 12-15 grams of protein per day for their bodies to properly operate. The FDA "buffered" that amount, to about 22, and then doubled it (for some unknown reason) to put the "recommended" protein intake somewhere around 45 grams/day. That amount is actually not a healthy amount of protein to be consuming daily - excess protein (amino acids) raises the blood's acidic levels. In order for the body to regulate pH, it puts calcium - a base (stored in the bones) - into the blood stream. More protein => more calcium needed to neutralize => (possibly) osteoperosis. (NOTE: osteoperosis is a bone disease caused by Calcium LOSS, and not by insufficient calcium. Insufficient calcium can bring about another condition called osteomalacia, which is usually only seen in children. Children's bodies with forming bones require more calcium than adults'). One cup of orange juice contains 3 grams of protein. That's more than one-fifth of the amount that your body actually needs in a day. (a news report on one such speaker can be read he http://flathat.wm.edu/story.php?issu...6&type=1&aid=4 - it's not bundled with "sited facts" or anything, but an interesting read, and may give you some research ideas). -jessigurr |

It depends if you include nuts, they have about twice or more the protein of meat - but humans really do not need concentrated protein sources at all. The really important things are vitamins, minerals and phytonutrients. So long as you get enough food energy, you are unlikely to be protein deficient so long as you eat a good variety of food.
