Nuts

Nuts not only serve as a mid-afternoon pick-me-up, but they are also an effective anti-ageing snack – many nuts are enriched with the trace element selenium, which according to a 2003 study published in the British Journal of Dermatology, can protect the skin from oxidative damage. Brazil nuts are a popular go-to source of selenium, which also contributes to good mind health.
