Funnily enough, the first nut on this list is botanically-categorized as a seed of the pistachio tree, but its nutritional content is so close to that of other nuts we typically consider it a nut.

Finally, macadamia nuts contain compounds called tocotrienols, which may protect brain cells from degenerative conditions like Alzheimer’s and Parkinson’s disease.
