from all the research i have read, the body makes its own protein by combining different amino acids. From what i gather it is a myth that you need to eat protein to get protein.

when you eat protein the body breaks it down into amino acids and rebuilds those into new useable proteins.

you dont need to eat protein to get protein. that being said that are certain amino acids produced during the breakdown of protein based food that are essential for building healthy proteins in the body. but these are a small portion of the essential amino acids required, most, if not all of which can be found eating fruits.

Steffen,

I am not an elite athlete, just some endurance hiking and weight training for past 30 years and too was concerned with lower protein intake until I studied Dr Kevin Tiptons studies recommending 1.2-1.4g per Kg for endurance and not more than 2g for weight training.  Been on the high carb diet for 6 months now, same weight training program and have actually put on some impressive size due to the increase in carbs.  Following the 1.2g/Kg which would bring someone on a 3000 cal diet and weighing 75Kg to 11-13% protein.  Just google Kevin Tipton studies on protein for athletes.  Hope that is helpful.

Jack

Thank you. Definitely helpful. Interesting writing from Kevin Tipton! How do you make an intake of 11-13 % I find it hard on a vegan diet and even harder on the raw vegan diet.

I fluctuate back and forth sometimes using raw rice protein powder for my weight training where I easily get my 11%; for endurance all of that is eliminated and an additional 800-1000 calories carbs added to get close to 9-10 %

I've cut my protein to practically zilch and have suffered no ill consequence. In fact I couldn't get through trig and calculus until doing so. I find it has a drugging effect, when protein is taken out of people's diet they complain of a lack of satiation, a feeling of anxiety was also reported.

There is nitrogen in protein, not in carbs fats etc.. interestingly enough heroin cocaine and l.s.d. are "high in nitrogen". Protein intolerance , checked for at birth by heelprick to measure phenyl alanine levels, or P.K.U. results in severe retardation... there are people who must not eat protein for reasons other than peanut, gluten allergies...

Human breast milk is less than one per cent protein, very low, about a quater of cow's milk and much less than rat milk and/or the standard meditteranian diet at about 20% protein. A carnivores digestion is three times more acidic and three times shorter. The digestion of protein, when amylase is the enzyme produced [to breakdown starch mainly] is only effective about 20% of the time and that in an overly acidic environment. Also the kidneys must cleave the nitrogen during the absorption of protein.

animal protein is expelled by the body in two days, three days for plant protein..according to excretion studies which track nitrogen .

post-menopausal women whose kidneys can no longer process protein are correlated with dementia.

What with all the brain proteins gunking up like alzheimer's. and parkinson's I'm pretty leary of protein now. these same branched amino acids touted for muscle repair and development by whey protein sellers are the indicators used to measure the consumption of cancer cells, cancer needs amino acids too.
