A study examining men’s protein intake finds associations between dietary patterns and testosterone levels. Researchers analyse the diets of 2,546 men aged 42 to 60 and report that higher overall animal protein consumption correlates with lower testosterone. They also find that higher plant protein intake is associated with higher testosterone.
The reporting focuses on the role of meat and dairy within animal protein. Times of India notes that dairy protein is linked with lower testosterone but emphasises the study cannot prove cause and effect. Mail Online and the Daily Mail frame the findings more directly as an outcome of eating more meat and dairy, summarising the same general result without additional detail on plant protein or the limits of correlation.
Overall, outlets agree on the central association: greater meat and dairy intake is linked with lower testosterone levels, while the research design does not establish whether diet causes changes in hormone levels.
