Nearly all so called "health foods" are actually unhealthy in many regards, especially nuts, legumes, many seeds in general, vegetable oils, fatty fish, fish oils, etc.
Many naughty nutrients are actually healthy, especially sugar, saturated fat, cholesterol, salt, etc.

Polyunsaturated fats and poor collagen synthesis cause heart disease.
Sugar doesn't cause diabetes.
Polyunsaturated fat causes diabetes.
Sugar actually assists in the treatment of diabetes.

Testosterone isn't the ultimate masculinizing hormone. In fact, going out of your way to raise testosterone specifically tends to raise estrogen through aromatization.
Dihydrotestosterone is much more potent for masculinization.
Dihydrotestosterone doesn't cause baldness or prostate cancer.
Male pattern baldness is multifactorial but teenagers, who have the highest DHT of any age group, have lower rates of baldness and prostate cancer, but older men have higher estrogen ratios and lower DHT, but DHT still gets the blame in the popular media.
Increasing serotonin does not treat depression. In fact, it makes you sadder, more autistic, promotes feelings of helplessness.
Dopamine and allopregnanolone treats depression and loneliness.
There, I just gave you a small guide to scrutinize many of the health gainz goblins that will try to coerce you into dying sooner. I realize I haven't given a single citation here, but I figure if you really want to know you'll just look at the research and find out yourself. Okay, I'm being lazy tonight, but I want to see some (you)s. Otherwise, I expect you to react autistically like I just claimed the earth was flat or something. People like that don't want evidence anyways. The only pitfall is if you accidentally read observational studies instead of research with an experimental design. Observational studies are full of misleading information. If you take one thing away from this post, stop eating polyunsaturated fats and get a decent amount of carbs.
