Cashews
If you’re out of snacking ideas, cashews should be the first thing to pop into your head (or, better said, bowl). Because cashews contain high amounts of zinc, the mineral that plays an essential role in the brain’s health, you should eat them whenever you can.
Numerous studies pointed out that a zinc deficiency is often responsible for the development of depression, memory impairments, and even aggression. In general, those who deal with depression have lower zinc levels than healthy people.
Men should aim for 11 mg of zinc per day, while women for about 8 mg. So, considering that one ounce of roasted cashews packs approximately 1.6 mg of zin, cashews are the answer.
