The famous physician John Harvey Kellogg had some serious beliefs about sex and masturbation. Almost all of them bad.
In fact, Kellogg apparently never consummated his marriage and adopted all of his children because of his beliefs.
He also cataloged 39 different symptoms of a person plagued by masturbation, including general infirmity, defective development, mood swings, fickleness, bashfulness, boldness, bad posture, stiff joints, fondness for spicy foods, acne, palpitations, and epilepsy.
Interesting, because this is the person who changed the worlds popular food choices and he based those choices on the belief that his recommendations would prevent sexual activity! Kellogg believed animal and seafood would increase testosterone and thus increase sexual activity, while grains and sugar would decrease testosterone and sexual activity… giving him the intended effect for his patients.
Moral of the story… in order to find the right nutritional choices, it is often important to look at and question where those ideas or fad diets originated from.
