Are foods cooked in soybean oil bad for men? i heard soy products are not good for men. same for soybean oil? thank you.

Too much is no good: Soy products have been dietary staples in asia for hundreds, if not thousands of years. Soy can contain compounds that affect thyroid function, and can be mildly estrogenic. Excessive intake, especially of processed soy products, e.g. Texturized soy protein, as opposed to natural sources like edamames, tofu, tempeh, could conceivably be a problem; mostly not. Soy oil doesn't have those chemicls.

Depends: Other than allergies to soy, one problem is that too much soy may affect the thyroid by exerting phytoestrogen effects. That means estrogen like effects in addition to competing with the thyroid for binding sites leading to low thyroid function. Also, the issue of gmo may be a health concern for some.
