Cholesterol is a waxy substance found in every cell of the body and is essential for producing hormones, vitamin D, and bile acids that help digest fats. Cholesterol is transported in the blood via two main types: LDL (low-density lipoprotein), often termed “bad” cholesterol, which can lead to plaque buildup in arteries, and HDL (high-density lipoprotein), known as “good” cholesterol, which helps remove LDL from the bloodstream. Maintaining a balanced cholesterol level is significant in nutrition, as high levels pose risks for heart disease and stroke, necessitating a focus on dietary choices.
