I've read so much crap, It's getting silly now. I JUST WANT A MEAT FREE DIET!
First, by many vegetarian/vegan sources, I was told how Soya had all 8 essential amino acids, and with it's high BV was as good as any meat product.
After tofu wasn't as effective as meat for me, i looked into it only to find another site saying soya is deficient in some of those amino acids and needs to be combined in the diet with other protein sources to "complete the full spectrum of essential amino acids"
OK, fair enough.. so besides Soya what else should i put in my diet to be fulfilled with each of those essential amino acids?
Now this gets funny now...
From http://www.sunnysidenaturalhealth.com/i ... ein_PH.doc
To obtain the essential amino acids from vegetable proteins in good proportion they need to be combined together. Grains contain a lot of tryptophan and not much lysine whereas pulses contain a lot of lysine but not much tryptophan. "
Here they say beans contain "a lot of lysine".
But on the next website, they say the complete opposite!!
http://altmedicine.about.com/cs/dietary ... tarian.htm
Plant proteins tend to be limited in one or more essential amino acids. For example, beans are low in the amino acid lysine, while rice is rich in lysine.
Low in lysine? But I just read the complete opposite?
It has been so frustrating looking into this. Can I believe anything I read? Shall I just give up and eat free range meat, at least I know I am safe there.
Enough of this, I have to now look into the full amino acids profile of individual foods. I never imagined taking it this far or wanted to spend all these hours, but i'm choiceless.
Worlds Healthiest Foods provides a breakdown of what amino acids each food contain. this is Tofu:

Amino Acid ---- %of Daily Value
cystine | 31.71
histidine | 20.93
isoleucine | 39.13
leucine | 27.67
lysine | 25.53
methionine | 16.22
phenylalanine | 37.82
threonine | 29.84
tryptophan | 43.75
tyrosine | 31.96
valine | 31.29
It appears Tofu lacks METHIONINE. So where do we get our methionine? What plant source has plenty of Methionine? I certainly can't find any. If WHF is a guide, all plant foods seem to lack methionine.
And another thing, to get a comparable amount of amino acids as a Chicken breast, one would have to consume around 15 ounces of Tofu. That is LOADS, I could never eat that much in a meal.
I feel like giving up, I just don't think this diet can work as well as a meat diet... as sad as that is.
I compete in boxing and martial arts, so diet is very important. This means training twice or sometimes 3 times a day. I need an awful lot of protein to repair my body from these workouts.
But then athletes such as Carl Lewis were successful on a vegan diet? How is it possible?
