Re: The protein myth
Dammit easy! Now who are we going to argue with?
Example: An avid drinker tells you that he's never felt better since consistently drinking 9 shots of vodka a day. Are you then going to say those of us who haven't been getting housed for breakfast have been doing it wrong because Jim Bob successfully does?
The correct answer is, no.

All based on that bull **** study!
I think it creates debate and food for thought (pardon the pun). It also means people can discuss the issue providing various evidence rather than relying on personal bias and/or preference. JudoJosh- though I have had opposite opinion- has provided useful evidence based on studies.

If congress can label pizza as a vegetable for school lunches, can I have them lablel eggs as plants too? I think I could cope with eggs as my only source of protein

If you cook a steak your then kill the protein? If you bake your hemp seeds does that kill your "live protein" it's ignorant your statement and completely close minded. I myself eat healthy, I eat protein from various sources, whey, protein isolate, casein, cottage cheese, milk,chicken, spinach, and yes hemp seeds. Humans evolved eating both plants and meat, just look at our ****ing teeth son! Back in golden age of bodybuilding what did Arnie, Zane, ferrigno and the likes eat? ****ing eggs, chicken, steak, potatoes and look at them the evidence is clear, they got the nutrients they needed. Eskimos eat diets of almost pure "dead animal" protein. I get what you are saying, it kinda makes sense, but its untrue. If I'm wrong ill gladly accept it and shake your hand, but show some studies, some real evidence backing up your close minded claims. I'm not smart and I'm not qualified these are my personal opinions, show me I'm wrong and ill gladly make a change. Till then

My Apologies in advance for writing a book
Protein - all protein - is digested in the stomache and upper part of the large intestine. Here is a simplified description of the process
Protein digestion begins in the stomach, chiefly with the action of the hydrochloric acid that is produced there, and by the enzyme called pepsin (PEP-sin). Some seven or more factors influence how fast the enzymes act on the protein. These factors include the concentration of the enzyme, that is, how much of it is present; the amount of protein food needing action; the acidity of the food and of the stomach; the temperature of the food; time; and the presence of any digestion inhibitors, such as antacids. Cooking and chewing help, but protein digestion does not begin in the mouth, as carbohydrate metabolism does. The hydrochloric acid in the stomach is required to break the protein bonds. The protein-containing foods are broken apart, separating out the protein, then the proteins are broken into their constituent parts, the amino acids.
Protein digestion continues in the upper portion of the small intestine under the action of the pancreatic protein enzymes, trypsin (TRIP-sin) and chymotrypsin (KI-mo-trip-sin). The amino acids are absorbed by the blood capillaries of the small intestines, carried through the liver, and then go into the blood of the general circulation. Recall from our discussion of carbohydrate digestion that absorption is done by means of selectively permeable membranes of the small intestine walls, which are arranged in folds called villi.
So, whether it is plant proteins or animal proteins - they are digested through similar pathways. Cooking helps digest proteins as it starts the process of breaking open the complex structures which makes the stomach acid be able to get at it more easily.
The OP is correct that raw foods have more active digestive enzymes associated with them. But the idea that protein from "dead" meat is treated any differently in the stomach than a protein molecule from a "live" bean is hogwash. Eating lots of meat does require a lot of stomach acid, and some people who are low acid producers can have a hard time digesting meat proteins - and may do better on a vegan or lacto ovarian (milk and eggs) diet. Taking Betaine HCl before meals has been a standby of the bodybuilding industry since the Vince Gironda days - the Betaine improves methylation in the liver while the HCl increases stomach acid and protein digestion. One can also supplement digestive enzymes.
Interestingly, there are arguments that the stomache has a really hard time when asked to digest complex carbs and protein at the same as it requires two different conditions (low acid for the carbs and high acid for the protein). So live foods like beans can be especially hard to digest and get the protein from.
The OP is completely irrevocably wrong when it comes to bio-availability of proteins. Numerous documented scientific studies have been done on bio-availability ( essentially this is a scale which rates how much of the protein in the food becomes available to the body when it is ingested - with a whole egg getting a rating of 100). From the table below - you see that meat eggs and dairy top the bio-availability list - and plant sources are much lower. Basically it says if your daily require for protein was 200 grams - you would need to eat almost 500 grams of protein (from peanuts) to give you that 200 grams since the protein is only 40% available.
Protein Source Bio-Availability Index
Whey Protein Isolate Blends 100-159
Whey Concentrate 104
Whole Egg 100
Cow's Milk 91
Egg White 88
Bottom line - There is no right way to eat - it is a personal choice. There is no good data to support that vegans get protein more efficiently - in fact the opposite is likely too. The human body uses animal protein very effectively.

Oh - and Beef makes me like to "engage in coitus" ( since f*ck is apparently not allowed) - unlike Soy and this boy
research has focused on the beneficial effects of soy and its active
ingredients, isoflavones. For instance, soy consumption has been associated
with lower cardiovascular and breast cancer risks. However, the number of
reports demonstrating adverse effects of isoflavones due to their estrogenlike
properties has increased. We present the case of a 19-y-old type 1 diabetic but
otherwise healthy man with sudden onset of loss of libido and erectile
dysfunction after the ingestion of large quantities of soy-based products in a
vegan-style diet. Blood levels of free and total testosterone and
dehydroepiandrosterone (DHEA) were taken at the initial presentation for
examination and continuously monitored up to 2 y after discontinuation of the
vegan diet. Blood concentrations of free and total testosterone were initially
decreased, whereas DHEA was increased. These parameters normalized within 1 y
after cessation of the vegan diet. Normalization of testosterone and DHEA
levels was paralleled by a constant improvement of symptoms; full sexual
function was regained 1 y after cessation of the vegan diet. This case
indicates that soy product consumption is related to hypogonadism and erectile
dysfunction. To the best of our knowledge, this is the first report of a
combination of decreased free testosterone and increased DHEA blood
concentrations after consuming a soy-rich diet. Hence, this case emphasizes the
impact of isoflavones in the regulation of sex hormones and associated physical

and if you want the definitive answer ( and more about protein than most of us want to know )
replace the yyy with www - it wont let me posst links yet

Gorillas are omnivores just like humans they like red bloody meat just like we do. I do like the hemp protein and breast milk though (kinda miss my wife being pregnant).

humans have the amazing ability to learn from their experiences and the amazing ability to not do so. reminds me of a quote from einstein, the 2 most abundant things in the universe are hydrogen and human stupidity and im not so sure about helium.
you can call me "ozzie" for short.

the only thing i can even come close to agreeing with you is that animal meat does not digest as well in our bodies as it would in a carnivore. but guess what, we are not carnivores. we are omnivores. so again not a valid argument.
and how is animal protein not natural. i have not ready past this post yet but you keep saying its not and i have not read why its not. you have made the claims, can you back them up with science from peer reviewed research journals?

gravity is a theory, it is also a fact it exists. try again. this is not argument, it is facts. science FTW.
