Protein intake and depression among athletes

Previous blog posts have discussed nutrition strategies for depression.

A recent study looked at depression and protein intake in young student athletes.

What was this study?

97 adolescent elite athletes were recruited for the study. Symptoms of depression were recorded at baseline and again during a follow-up at 10 months (1)

A 3 day dietary intake log was obtained 3 months into the study(1)

What were the results?

Higher protein intake was associated with a reduction in symptoms of depression during the follow-up period (1).

What are some general protein intake guidelines?

This calculator can help get an estimate of protein intake, https://www.nal.usda.gov/human-nutrition-and-food-safety/dri-calculator

However, according to the most recent dietary guidelines for Americans, almost 90 percent do not meet the recommendation for seafood and more than half do not meet the recommendation for nuts, seeds (2)

International Society of Sports Nutrition that the majority of exercising individuals should consume at minimum approximately 1.4 to 2.0 g of protein per kg of bodyweight per day to optimize exercise training induced adaptations. (3)

What are some caveats?

This is a small study showing association not causation.

Study authors call for larger and more in depth assessment and techniques.

Athletes and people who exercise regularly may require protein intake that is higher than the Dietary guidelines for Americans.

An optimized and personalized approach to nutrition can help with both physical and mental health (see resources below like nutrition coaching).
