There are increasing number of studies showing that the things we eat can have an impact on our insomnia, anxiety, irritability, energy level, etc.
A recent study looked at fish intake and odds of developing depression.

What did the study involve?
This was a review of 26 studies, involving 150,000 adults; one of the largest studies of its kind.

What did the results show?
After adjusting for many variables, those who ate the most fish had a 17% lower risk of depression than those who did not.

How much fish was eaten by those who had the most benefit?
• The exact amount of fish intake is not clearly established.
• Some people think that the amount that’s beneficial may also be dependent on what else you are eating (vegetables, high quality protein, good fats, whole grain) and what you are not eating (think junk foods, processed grains, etc).

What are some caveats?
• Reduced depression risk was statistically significant only in European countries.
• Omega 3’s might help by impacting serotonin and dopamine transmission in the brain (2–4); since these are important transmitters involved in depression.
• Quality nutrients like protein vitamins and minerals might also help with depression (5-6).

What’s the bottom line?
For some people, fish intake and eating nutritious foods (instead of heavily processed foods) might improve how you feel by improving brain and body functioning, hormones, etc.
How are your eating habits? Are you feeling lousy? Are you eating lousy? Ready to feel better?

What are some campus resources to improve nutrition?
• Nutrition coaching with student wellness
• Nutritionist at Wilce Student Health center
• Nutritionist at the Wexner medical center
• Nutrition books
• Take a nutrition class
