I mean walnuts, of course. When it comes to antioxidant quality, walnuts are at the top of the ground and tree nut category regarding health benefits, according to Food & Function.

They rank them above peanuts, almonds, pecans, pistachios, macadamias and all other nuts.

Joe Vinson of the University of Scranton in Pennsylvania says, “A handful of walnuts contains almost twice as much antioxidant as an equivalent amount of any other commonly consumed nut. But unfortunately, people don’t eat a lot of them.”

All nuts contain high-quality protein that can substitute for meat. They also have vitamins, minerals and dietary fiber. They are dairy- and gluten-free.

Studies link regular eating of nuts or peanut butter with decreased risk of heart disease, certain cancers, gallstones, type 2 diabetes and other conditions.

                     About seven walnuts a day deliver the health benefits.
