And yet Asians are one of the most successful racial groups in terms of population. Low sex drive should mean low reproduction, but that clearly isn’t the case.
Is it, though? Citation? Other factors in low T are low levels of exercise, stress and other dietary factors. You’re suggesting a uni-variate answer to a multi-variate question. What about refined sugar and white flour? What about alcohol? If you’re going to say soy is the MAIN contributor, perhaps some evidence in the form of a link to at least one study?
That’s not an example. You just made up an anecdote, but provided no real evidence at all.
How is it scientific? Citation? Middle eastern and southern European men have much more pronounced body hair and thicker beards than fair haired northern Europeans. Do they possess greater levels of T? Do you know this for certain? “Scientific?” Citation?
A racial characteristic, not one caused by diet. You really should meet some Asian lifters. They don’t have “soft bodies” at all. But, hey, please do back up your claims with citations.
The Japanese diet has persisted for centuries, if not longer. The modern Japanese otaku is the result of social and technological changes, not diet.
Fallacy of false causes. The traditional diet here is not new. If it is responsible for the current low birth rate, how do you explain the high birth rate times, given that the diet was likely even MORE soy based than now (meat was too expensive) than now? But, then, we already know why the birth rate has fallen. You can see the same phenomenon in virtually any developed country. Factors include economic considerations (wages, housing costs, costs to raise children) as well as prioritizing individual pursuits, women’s rights and others. A uni-variate explanation of complex phenomena just does not do here without at least some citations.
