EnglishDave,

I am in two minds after reading the conclusion because I am obese.

Soy is eaten by many people in Asia though Indians actually eat very less of it
to be frank.

Indian diet is extremely low in protein - just 10-20 g daily even in
rich ,wealthy people. Many people do not eat non veg food and those who eat do so in less quantity.

Thats why Indians are not physically active - they dont have the MUSCLE POWER.They cannot excel in sports that require physical stamina like football /swimming.
