2. Spinach
A deficiency in folic acid or magnesium can worsen depression and fatigue. Fight those negative feelings with a cup of spinach, which supplies 40 percent of your daily needed magnesium and 25 percent of your needed folic acid. Also, the diabetes research unit at Leicester University reported earlier this month that a serving and a half of spinach or other green leafy vegetables each day can lower the risk of Type 2 diabetes. That should cheer you up.
