the point was it is debatable whether soy is healthy or not , some studies still show it is detrimental whilst other studies possibly funded by big agriculture show it to be healthy
And the studies showing negative aspects are usually done in rats who are given massive amounts of isolates. A common trick used to make substances appear dangerous. Luckily we are not rats and we do not consume the equivalent levels of isolates or strictly eat soy.
What is really interesting is how nations where soy is heavily consumed, such as China and Japan they are so much healthier on average than Americans. And the women in these countries that eat the traditional Asian diet high in soy products do not go through menopausal symptoms and have lower incidences of estrogen fed cancers.
