How much cholesterol per day is too much?

The Daily Value of 300 milligrams per day is actually an upper limit, not a minimum daily requirement. You don't actually need to consume any cholesterol.

According to Dr. John McDougall, MD, “As an animal, you make all the cholesterol you need. Unfortunately, your capacity to eliminate it is limited to a little more than the amount you make. As a result, the cholesterol added by eating animal foods accumulates in your body parts, including your skin, tendons, and arteries. Cholesterol deposited in your arteries is a major contributor to vascular diseases of your heart and brain. Cholesterol also facilitates cancer development.”
