|One of the reasons peanuts are favored as a food item is because of their nutritional value and the fact that they don't easily spoil for long periods of time. In cooking, peanut oil is healthier in comparison to saturated oils since peanuts are free of trans-fat. Peanuts have over 30 essential nutrients and phytonutrients and are a good source of fiber, magensium, phosphorus, manganese and vitamin E among other. Since they contain niacin, they contribute to blood flow to the brain. Research has shown that peanuts have "resveratrol", which has anti-aging effects and reduces cancer risk and also reduces cardiovascular diseases.
