If the arteries become narrow, the blood will need to work harder to get itself (and vital nutrients and oxygen) around the body. If you aren't careful, the heart muscle may tire out completely. Here's one food you could do with eating less of.
Cholesterol is a fatty substance, also referred to as a lipid, and there are two main types — LDL (bad) cholesterol and HDL (good) cholesterol. HDL stands for high-density lipoproteins and LDL stands for low-density lipoproteins. This is labelled ‘bad’ cholesterol because high levels can lead to a buildup of cholesterol in your arteries. While some cholesterol is vital for normal function of the body, having high cholesterol can narrow the arteries and lead to heart attack and stroke.
