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.
But that is a stupid answer. Just because something ways a pound, doesn't mean it is equivalent to 2 cups. Saying that 2 cups of anything equals a pound is like saying a cup of rocks equals a cups of feathers. Anyway, a pound of peanut butter typically ranges from 1 3/4 cup up to 2 1/4 cups. It really depends on the amount of fat in the product. the more fat the more it will weigh and the more volume it will take up.
