Protein Source Shapes Male Hormone Levels
Does Meat Lower Testosterone?
Researchers at the University of Eastern Finland found that the type of protein men eat directly influences their testosterone. The study, published in the International Journal of Food Sciences and Nutrition, reveals a clear split between animal and plant sources.

Why Plant Proteins May Boost Hormones
The data indicates that higher consumption of animal protein, such as meat and dairy, correlates with lower testosterone. Conversely, men who rely more heavily on plant-based proteins like legumes and nuts showed higher hormone levels. This suggests the source of protein matters more than the total amount consumed.
Plant proteins often come with higher fiber and phytochemicals, which may support hormonal balance. Animal proteins, particularly from processed meats, may introduce compounds that interfere with steroidogenesis. The study highlights that dietary shifts toward plant sources could be a simple intervention for men seeking to optimize their hormone profile.
Does this mean men should stop eating meat? No, the study shows an association, not a strict cause-and-effect. However, increasing plant protein intake may help maintain healthy testosterone levels.
Frequently Asked Questions
How large was the study group? The research involved a significant cohort of adult men, providing robust data for the International Journal of Food Sciences and Nutrition.
Can diet really change testosterone levels? Yes, the findings suggest that dietary protein source is a modifiable factor. Men can influence their hormone levels by adjusting their protein sources.
