Your body needs cholesterol in small amounts to function properly. Consuming too much of it increases your risk of heart disease over time. The cholesterol in lobster poses little harm if you consume a balanced diet and your cholesterol is within the target range. Health care providers recommend restricting cholesterol in your diet if you have heart-disease risk factors. This means you may need to avoid foods such as lobster, until your cholesterol is under control.
Limit cholesterol to 300 milligrams per day if you are healthy, and less than 200 milligrams if you have heart disease or high cholesterol, suggests the American Heart Association. Lobster contains high amounts of cholesterol. A typical four to 6-ounce serving contains 165 to 248 milligrams, according to the U.S Department of Agriculture.
