Eating more cholesterol in your diet seems to make middle-aged male smokers more likely to die earlier, especially from heart disease. For every extra 300 mg of cholesterol eaten daily, the risk goes up by about 10% for all causes of death and 13% for heart-related deaths over 31 years.

Men who smoke and have higher cholesterol levels are more likely to die from heart disease. For every increase of one standard deviation in cholesterol, their risk of dying from cardiovascular disease goes up by about 14%.

Eating foods with cholesterol won't raise your chances of heart problems if you're a generally healthy person, according to recent research reviews.

In US adults who eat less than 250mg of cholesterol daily, eating a bit more cholesterol seems to be linked to living longer, with each extra 50mg per day associated with about 13% lower risk of dying from any cause.

If you're an adult in the US eating at least 250mg of cholesterol daily, research suggests that adding just 50mg more cholesterol to your diet might increase your risk of dying from any cause by about 7%.

Eating more cholesterol might actually be linked to living longer if you eat small amounts (under 250mg daily), but eating lots of cholesterol (250mg or more daily) seems to be linked to a higher risk of dying from any cause.
