Role Of Dietary Protein And Thiamine Intakes On... May 2026

Thiamine acts as an antioxidant and essential regulator , supporting DNA repair and reducing oxidative stress in cells.

While some cross-sectional studies suggested better cognition with higher thiamine, the overall data remains inconclusive due to a lack of experimental trials.

There is currently weak evidence linking higher protein or thiamine intake directly to better cognitive performance in healthy older adults. Role of dietary protein and thiamine intakes on...

A systematic literature review published in Nutrients investigated the Role of Dietary Protein and Thiamine Intakes on Cognitive Function in Healthy Older People. The review appraised 17 eligible studies to determine if these specific nutrients could delay cognitive decline in aging populations. Key Findings on Cognitive Health

Beyond the primary review on cognition, dietary protein and thiamine are critical for broader health outcomes: Thiamine acts as an antioxidant and essential regulator

Adequate intake of these nutrients is likely a marker for "good overall nutritional status," which collectively supports cognitive health rather than the nutrients acting in isolation. Metabolic & Cellular Roles

No evidence supports that specific protein sources, such as different types of meat, have a unique impact on cognition. Metabolic & Cellular Roles No evidence supports that

Thiamine (as thiamine pyrophosphate) is a mandatory cofactor for enzymes that metabolize glucose, lipids, and branched-chain amino acids (from protein). Physical Performance: High protein intake (
