Cholesterol gets a bad rap 1. This fatty substance, also known as a lipid, is often shunned by health enthusiasts. However, bad reputation aside, cholesterol plays several vital roles in the body. For starters, it acts as a precursor to vitamin D and the sex hormones estrogen and testosterone, which play a role in reproductive health. Cholesterol also makes up the outer coating of your cells and enables your body to make bile -- a substance needed to properly digest fats 4.

Know Your Limits

According to the Institute of Medicine, the body can synthesize all the cholesterol it needs to function. Because of this, cholesterol recommendations are given as an upper limit, rather than an recommended dietary allowance or RDA. The current recommendation from the Food and Nutrition Board, which is a subgroup of the Institute of Medicine, is to consume no more than 200 milligrams of cholesterol per day.
