Lobster is high in cholesterol. Three ounces of lobster contains 61 milligrams of cholesterol, which is about one fifth of the recommended daily intake. Patients diagnosed with high cholesterol or heart disease should avoid eating lobster.
Research has shown, however, that lobster does not significantly increase cholesterol levels in most people. Lobster is also a good source of Omega-3 fatty acids, which help reduce blood pressure and triglycerides. Most doctors agree that trans fats are the primary source of bad cholesterol. Artificial trans fats found in fried foods, margarine and refrigerator dough have been linked with high rates of heart disease and stroke.
