Research has found that peanuts rival the antioxidant content of blackberries and strawberries. They are rich in antioxidant polyphenols, including coumaric acid, to help thin the blood, and resveratrol, which can protect against hardened arteries. They have high vitamin E content, an antioxidant linked with heart and arterial health, brain power, and protection from strokes, heart attacks, and cancer. Peanuts contain mostly monounsaturated fat, which has a better effect on blood cholesterol levels than polyunsaturates. They are a good source of the amino acids tryptophan, which helps boost mood, and l-tyrosine, which is linked with brain power. Rich in antioxidants, which protect against heart disease. High in amino acids to boost mood and brain function. Contain phytosterols, which may help prevent colon cancer. Rich in monounsaturated fats, which are linked with protection against heart disease.

Practical tips:

Ideally, buy peanuts in their shells, or at least in their skins—they will keep for longer. Fresh peanuts should smell fresh, not musty. Buy unsalted peanuts and store them in a refrigerator—their high oil content means that they don’t last long in warm conditions. Make your own healthy peanut butter by blending with a little peanut oil until it has a good spreading consistency.

Peanuts, also known as groundnuts, are not in fact true nuts but members of the legume family, like peas or beans.
