If you look at vegan bodybuilders, even ones that consume no nuts and are fruitarian, most of them are more muscular than meat eaters..why? Becasue you dont need protein..yes thats right, contrary to popular belief the body does not require any protein.
Amino acids are what build muscles, not protein. Protein is the middle man and the body has to expend alot of energy in order to convert protein into the amino acids it uses to build muscle. Fruits and vegetables are loaded with muscle building amino acids that lend themselves to muscle development more than protein does..you just have to eat them raw. If you cook them, you also destory those same amino acids. This is something that alot of people dont know and the whole protein myth just continues.
Asinine. Fruitarian bodybuilders? Wherever have you seen these impossible creatures?
Protein is absolutely essential to the healthy functioning of the human body. This is not a disputed fact in any credible area of nutritional science.
Protein is simply a collective term for any given combination of amino acids. It can can be readily broken down into constituent free aminos by anyone with a functioning stomach and pancreas, and since every cell in the body is in a continuous state of protein turnover, a full range of free aminos (difficult to accumulate via vegetable sources, outright impossible via fruit) is required at all times. Exactly how much a person needs depends on a great many factors, but for anyone weighing more than a small child and with activity levels higher than a slug, 0.5g per lb of lean body mass would be considered minimal. For purposes of muscle building, 1g/lb lean mass at least. And all protein sources should be as varied as possible (i.e. not derived strictly from one narrow food category) in order to accumulate the full range of aminos required by the body's tissues.
Excess protein (somewhere in the absurd ballpark of more than 2g/lb of lean body mass) consumption is easily dealt with by a pair of healthy kidneys and cycled into urea. Eating insufficient calories, as is quite likely to result from a strictly plant-based diet, sequesters free aminos away from cell renewal and into energy metabolism, meaning the body is much less able to repair itself. Chronic catabolism is not a desirable state for any organism to be in, and it should not be recommended.
I gotta disagree with ya as well Fractal. The body needs protein in order to function properly. However, I don't believe that you really need to eat meat in order to get all of your required protein.
Here are a couple of sites that list high protein plants to supplement a vegan/raw diet.
50 Foods High in Protein
Protein in the Vegan Diet
High Protein Vegetables - Relates to a veggie based mass building diet.
Spirulina - 68% Water Soluble Protein - Containing all 8 essential amino acids and a total of 18 in all, it is established among many as a "supreme" protein. In nutritional studies it comes in as a higher digestible protein source over beef, 12 times higher, with a much healthier balance of minerals and other nutrients.
There are definitely ways to achieve all of your protein needs without resorting to eating animals.
