Article Synopsis
- A study with 25 healthy young adults used a randomized crossover design to assess mood changes after following high and low tryptophan diets for 4 days each, separated by a 2-week washout period.
- Participants reported significantly higher positive mood scores (p<.01) after the high tryptophan diet, but the difference in negative mood was not significant (p>.05).
- The results also indicated that increased dietary tryptophan was associated with lower depressive symptoms and decreased anxiety (p<.05).
The purpose of this study was to investigate the effects of diet on cognition and flight performance of 45 pilots. Based on a theory of self-care, this clinical study used a repeated-measure, counterbalanced crossover design. Pilots were randomly rotated through 4-day high-carbohydrate, high-protein, high-fat, and control diets.
