7. Potassium
Without this mineral, the heart couldn't beat, our muscles wouldn't contract, and the brain couldn't work properly. Why? Potassium helps your cells use glucose for energy.
As critical as potassium is, nutrition surveys show that young men only consume 60 to 70 percent of the recommended 4,700 mg a day.
And when sodium levels go up, potassium levels go down. Unfortunately, many men load up on sodium.
Foods to shoot for include: avocados, bananas, cooked spinach or broccoli, mushrooms, peas and cucumbers.
8. Iodine
The thyroid gland needs iodine to make the hormones T3 and T4, both of which help control how well we burn calories. That means low iodine intake can cause weight gain and fatigue.
Many people might think, well I’ll just add a little salt. This may help if it is iodized salt, but U.S. manufacturers aren't required to use iodized salt. Because of this, we've been inching toward iodine deficiency since the 1970s.
Since dumping more salt on top of an already sodium-packed diet isn't the greatest idea, iodine can also be found in a nearly sodium-free source: milk.
You can also opt for one serving of eggs or yogurt a day: Both are good sources of iodine.
