They ate meat for more testosterone. However, the results of the blood tests surprised the scientists.

A Finnish study reveals that men consuming high amounts of animal protein have lower testosterone levels compared to those who eat more plant-based proteins. The research analyzed data from 2,546 men aged 42 to 60, finding that those with the highest meat intake had an average testosterone level 1.2 nanomoles per liter lower than those with the lowest intake. Conversely, men with higher plant protein consumption had 1.1 nanomoles more testosterone. The study suggests that the differences, while statistically significant, may not have a substantial impact on health. Other nutrients in foods could also influence testosterone levels, but the study did not confirm this. Further research is needed to explore dietary changes' effects on individual hormone levels.
