More than 90 percent of the weight of fat in foods and more than 95 percent of the stored fat in the human body are in the form of: triglycerides.

<h3>What is triglycerides?</h3>

Among fats, triglycerides are one. They make up the majority of the fat in your body. They originate in food, particularly in the butter, oils, and other fats you consume. Additionally, extra calories provide triglycerides. You consume these calories, which your body does not immediately require. These extra calories are converted by your body into triglycerides and stored as fat. The triglycerides are released when your body requires energy. The triglycerides are transported to your tissues by VLDL cholesterol particles.

Your chance of developing heart conditions like coronary artery disease is increased if your triglyceride levels are high.
