Triglycerides - What Are They?

Triglycerides are a type of fat in your blood. Oil, margarine, butter, and most other fats in your food are triglycerides and your blood absorbs them after you eat. But that’s not the only source. Your body also turns extra calories -- especially from “simple carbs” such as pastries, white bread, candy, sugar, and alcohol -- into triglycerides and stores them in fat cells.
