00:00What men eat for protein may be linked to their testosterone levels.
00:03Researchers at the University of Eastern Finland studied 2,546 men aged 42 to 60.
00:10The men recorded everything they ate for four days, and their blood testosterone was measured.
00:16Men eating the most animal protein had levels about 1.2 nanomoles per liter lower.
00:21That's compared with men eating the least!
00:23Plant protein showed the opposite.
00:25The highest plant protein group had levels about 1.1 nanomoles per liter higher.
00:30Dairy protein was linked to lower testosterone.
00:33Plant protein from vegetables and sources other than cereals was linked to higher levels.
00:38Meat protein wasn't linked to total testosterone at all.
00:41The differences were statistically significant, but small.
00:45And it's not clear whether they matter for health.
00:47It was a snapshot study, so it doesn't prove cause and effect.
00:51Still, the protein on the plate may tell a hormone story.
