The Claim
Higher intake of unprocessed red meat is associated with better general cognitive functioning and processing speed, with individuals in the highest intake tertile scoring 0.4 points higher on the MMSE and completing the trail making test 4.9 seconds faster than those in the lowest tertile after 4 years.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who eat more unprocessed red meat score slightly higher on cognitive tests and complete processing speed tasks faster than those who eat less, after four years.

Eating more unprocessed red meat provides more iron and B vitamins, which help brain cells make energy and build protective insulation around nerve fibers, allowing signals to travel faster and improving thinking speed and memory.
