Finland Study Ties Protein To Testosterone In 2,546 Men

Buzzline

A University of Eastern Finland study links the source of men’s dietary protein with testosterone levels, Euronews reports. Researchers analysed 2,546 men aged 42 to 60 and found the highest animal-protein group had total testosterone 1.2 nanomoles per litre lower than the lowest-intake group. For plant protein, the highest-intake group was 1.1 nanomoles per litre higher. The study examined associations only and does not show cause and effect; the report also covers dairy, meat and plant-protein findings and researchers’ comments on the size of the differences.

Transcript

00:00A new study from Finland links where a man's protein comes from to his testosterone level.

00:05Researchers at the University of Eastern Finland studied 25 and 46 men aged 42 to 60.

00:12Men with the highest animal protein intake had total testosterone, 1.2 nanomoles per liter lower.

00:18The comparison group was men with the lowest intake.

00:21For plant protein, the pattern reversed.

00:24The highest group was 1.1 nanomoles per liter higher.

00:27Higher dairy protein intake was linked to lower total testosterone.

00:31Meat protein was not linked to total testosterone.

00:35Plant protein from vegetables and sources, other than cereal products, was linked to higher levels.

00:40The researchers adjusted for age, body mass index, and other factors.

00:45The study is cross-sectional, so it shows associations, not cause and effect.

00:50Researcher Mika Wynne-Ellis said the differences were statistically significant, but relatively small.
