Hormones and diet: low insulin-like growth factor-I but normal bioavailable androgens in vegan men

N E Allen et al. Br J Cancer. 2000 Jul.

Abstract

Mean serum insulin-like growth factor-I was 9% lower in 233 vegan men than in 226 meat-eaters and 237 vegetarians (P = 0.002). Vegans had higher testosterone levels than vegetarians and meat-eaters, but this was offset by higher sex hormone binding globulin, and there were no differences between diet groups in free testosterone, androstanediol glucuronide or luteinizing hormone.
