Cholesterol is a waxy substance. It’s not inherently “bad.” Your body needs it to build cells and make vitamins and other hormones. But too much cholesterol can pose a problem. Cholesterol comes from two sources. Your liver makes all the cholesterol you need. The remainder of the cholesterol in your body comes from foods from animals. For example, meat, poultry and dairy products all contain dietary cholesterol. Those same foods are high in saturated and trans fats. These fats cause your liver to make more cholesterol than it otherwise would. For some people, this added production means they go from a normal cholesterol level to one that’s unhealthy.
