Fat causes obesity and many heart diseases. Americans have the bad habit of eating fatty foods like hot dog, hamburgers, ice-cream, chocolate, milk, cheese, nuts, doughnuts, pies, cakes and cookies. These foods contain saturated fats that raise the level of blood cholesterol. And doctors warn that eating foods high in cholesterol is bad for one's health. Usually most foods that come from animals are high in a fatty substance called cholesterol. Cholesterol, in high levels, is bad because it leaves fatty deposits in the arteries. These deposits narrow the arteries and stop the blood from flowing freely. This is very dangerous: a person may have a heart attack and die suddenly because the blood cannot flow to the heart of to the brain.
