Is soy a complete protein like animal or whey protein? I've heard a lot of conflicting information, and don't know what to believe...

1. Soy has a biological value of about 74

Protein BV

Whey isolate 110-159
Whey concentrate 104
Whole egg 100
Cow's milk 91
Egg white 88
Fish 83
Beef 80
Chicken 79
Casein 77
Soy 74
Rice 59
Wheat 54
Beans 49

2. It has all of the essential amino acids in roughly the same proportion as whey.

3. It has been shown to reduce testosterone levels in the prostrate but this effect has been shown to be tissue specific.

4. The Isoflavones in Soy are cancer fighting.

5. Stay tuned for a bunch of posts claiming that Soy will turn you into a woman. Believe what you will :)
