The Claim

Higher intake of processed red meat is associated with reduced verbal and visual memory performance, with individuals in the highest intake tertile recalling 2.5 fewer words on the selective reminding test and scoring 1.0 point lower on the visual reproduction test after 4 years compared to those in the lowest tertile.

In plain English

People who eat more processed red meat over four years recall fewer words and score lower on visual memory tests than those who eat less.

See the scientific wording

Higher intake of processed red meat is associated with worse verbal and visual memory, with individuals in the highest intake tertile recalling 2.5 fewer words on the selective reminding test and scoring 1.0 point lower on the visual reproduction test after 4 years compared to those in the lowest tertile.

Why this might work

Eating a lot of processed red meat causes chemicals in the blood to become more inflammatory and damaging to cells. These chemicals reach the brain, especially the memory center, and interfere with how brain cells connect and communicate. This makes it harder for the brain to store and recall words and images.

    Men who ate more processed meats like bacon and sausages remembered fewer words and did worse on visual memory tests four years later, exactly as the claim says.
