Micronutrients & recovery
Adherence to a Prudent diet (high in fruits, vegetables, lean protein, whole grains) for two weeks significantly increases plasma and urinary levels of 3-methylhistidine and proline betaine, serving as robust biomarkers for healthy eating patterns.
To objectively verify you are eating healthy, focus on a Prudent diet rich in fruits, vegetables, lean proteins, and whole grains. This study shows that just two weeks of this diet significantly alters specific biomarkers (3-methylhistidine and proline betaine) in your blood and urine, providing a clear, objective signal of healthy intake that self-reporting often misses. Ensure your caloric intake matches your needs to maintain weight while making these quality changes.
Overall, 3-methylhistidine and proline betaine concentrations increased in both plasma and urine samples after participants were assigned a Prudent diet (q < 0.05) with a corresponding decrease in the Western diet group.
Why this rating
Randomized controlled trial with rigorous metabolomic validation, though small sample size (n=42).
