Studies had it that they also possess high levels of polypenols, particularly the p-coumaric acid, which is known for reducing stomach cancer risk through inhibiting and limiting carcinogenic nitrosamines formation in the stomach.

Aside from these p-coumaric acids, peanuts also contain resveratrol, another type of antioxidant, which can help reduce your risks to certain cancers, along with degenerative nerve disease, heart disease, Alzheimer’s disease and fungal or viral infections.

Resveratrol may also help in reducing your risk to stroke by altering some molecular mechanisms in your blood vessels, lowering your chances in acquiring vascular damage by limiting the activity of angiotensin.

It is a systemic hormone working for blood vessel constriction that elevates your blood pressure. Peanuts also increase the level of nitric oxide, a vasodilator hormone.
