  • Triglycerides

    Triglycerides are a type of fat. They are the most common type of fat in your body. They come from foods, especially butter, oils, and other fats you eat. Triglycerides also come from extra calories. These are the calories that you eat, but your body does not need right away. Your body changes these extra calories into triglycerides, and stores them in fat cells. When your body needs energy, it releases the triglycerides. Having a high level of triglycerides can raise your risk of heart diseases, such as coronary artery disease.
