HIV (human immunodeficiency virus) is a virus that attacks the immune system, the body's natural defense system. Without a strong immune system, the body has trouble fighting off disease. Both the virus and the infection it causes are called HIV. White blood cells are an important part of the immune system.
One recommended serving of peanut butter is 2 tablespoons, which is about the size of a ping-pong ball. That serving contains about 188 calories, 145 of which come from fat. Thus, peanut butter is more than 75 percent fat; the 2010 Dietary Guidelines for Americans recommends limiting fat to just 20 to 35 percent of total calorie intake.
The main ingredient in peanut butter is ground peanuts. Oil is added to give it a smooth, creamy texture, but some oils are healthier than others. Honey, molasses or sugar help add a touch of sweetness to peanut butter. If the peanuts are not salted, salt may be added as a final ingredient to add more flavor.
