Fat, the most concentrated source of energy in your diet, is a vital nutrient. Saturated fat is the culprit that can raise the cholesterol level in your blood. This type of fat is found mainly in animal foods such as meats and whole-fat milk and cheeses. Peanut butter contains only 3 grams of saturated fat per serving. Peanut butter contains both polyunsaturated and monounsaturated fat.
Cholesterol is found only in animal products.
Peanut butter is naturally cholesterol-free. Trans fats are unsaturated fatty acids formed when vegetable oils are partially hydrogenated to make the fat more solid. A very small amount of partially hydrogenated vegetable oil is added to regular peanut butter to keep the oil from separating out, to increase the shelf life and to create a creamier peanut butter. While the small amount of hydrogenated oil in regular peanut butter hardly warrants mention, consumers wishing to avoid it can always select a natural peanut butter. Natural peanut butters do not contain partially hydrogenated oil.
