Cholesterol is a waxy, fat like lipid that circulates in your blood and is vital for cell membranes, hormone production, vitamin D, and bile acids. Your liver synthesizes most of it, while the rest comes from animal based foods such as meat, eggs, and butter. High levels, especially LDL, promote fatty deposits in arteries and cardiovascular risk.
To monitor this, you can use your cholesterol ratio calculator by entering your total cholesterol and HDL values.
