The unsaturated fats, protein, manganese and niacin in peanut butter provide a healthy boost to metabolism, reports SFGate. Eating peanut butter with breakfast and snacks increases metabolism and provides a feeling of satiety that helps people stave off hunger and avoid becoming overweight, explains Today Health. Eating peanut butter before bed keeps metabolism working and burning calories even while people are asleep, points out CNN Health.
Although the U.S. Department of Agriculture designates peanut butter as an oil because of its fat content, the fats it contains are unsaturated and healthy, according to SFGate. These fats help reduce the amount of harmful cholesterol in blood, which lessens the danger of heart disease and may benefit the cardiovascular system by impeding narrowing of the arteries. The manganese in peanut butter aids bone and tissue growth, helps wounds heal, and activates enzymes to remove body toxins. Manganese and niacin also protect cells and break down nutrients in food.
Because it is a dense form of nutrition, people should consume peanut butter in moderation even though it is healthy, SFGate advises. Peanut butter is high in calories, and people need to take care not to go over the daily oil intake of 5 to 6 teaspoons for women and 6 to 7 teaspoons for men that the U.S. Department of Agriculture recommends. Reduced fat peanut butter is not always a healthier alternative, because manufacturers replace the fat with sugar and salt, warns Fox News Magazine.
