Fox 17, Nashville, Study finds coffee linked to testosterone, body fat and metabolism,
especially in men
Researchers in Finland found that people who drank more coffee tended to have lower body fat, more skeletal muscle and different metabolic markers than those who drank less coffee.
The study also found a notable difference in sex hormones among men: Higher coffee intake was associated with higher total testosterone and higher levels of sex hormone-binding globulin, or SHBG, but lower free testosterone.
But before coffee drinkers celebrate, researchers stress that the study does not prove coffee causes these changes.
Good news, I guess. But I also wonder about the arrow of causation in this study. It could just be that healthier, more virile men just drink more coffee, for a variety of reasons.
