I'm looking for sources, excluding Wikipedia, that describe the health benefits of eating peanut butter. It would be nice if the facts were specific to crunchy peanut butter, but it isn't necessary. Peanut butter benefits compared to other popular foods would be awesome. Thanks!
One of the most interesting and peculiar nutrients found in peanuts is Resveratrol: this is a natural antimicrobial agent, produced by the peanut plant (and in even larger quantities by red grapes) to ward off potential pathogens
The minerals peanut butter contains are in variable amount (raw peanut butter with crushed skin contains much higher amounts than refined “nut-only” butter): iron is essential for the correct functioning of your red blood cells, while calcium promotes healthy bones and shields against muscle spasms.
Although not among the richest foods in potassium, peanut butter still contains fairly good amounts of it, and research has indicated that diets rich in potassium reduce the risk of hypertension (bananas are, however, a better source of potassium, try making a banana and peanut butter sandwich!)
Proteins are present in high amounts (about 24% in weight), together with very important micro-nutrients such as Vitamin E, Vitamin B3 and large amounts of beneficial minerals such as iron, magnesium, potassium, copper and calcium.
Vitamin E is one of the most powerful liposoluble antioxidants, shown to significantly reduce the risk of cancer and cardiovascular diseases; Vitamin B3 (also known as Niacin) is a water-soluble vitamin that aids in the recovery of cell DNA damage (thus protecting from cancer) and in improving sexual bodily functions by assuring the proper secretion of sexual hormones.
