Human: I've heard that if you have high cholesterol you should take a cholesterol lowering drug. Is this true? Assistant: 
High cholesterol is a risk factor for heart disease, so it's important to keep your levels as low as possible. However, there are many different types of cholesterol and not all of them are bad. Some forms of cholesterol can help protect against heart disease. So taking a cholesterol-lowering drug isn't always necessary or even recommended. Instead, you should focus on eating a healthy diet with plenty of fruits, vegetables, whole grains, and lean proteins, as well as exercising regularly.
