Cholesterol is a fat-like substance that circulates in the body. It is produced by the liver, but also, the body obtains it through some foods.
According to the Spanish Heart Foundation, this lipid is involved in the formation of bile acids, vital for the digestion of fats; the sun’s rays transform it into vitamin D to protect the skin from chemical agents and prevent dehydration, and certain hormones are formed from cholesterol, such as sexual and thyroid hormones.
