It used to be widely believed that eggs raise cholesterol levels. While it's true that eggs are high in cholesterol, that doesn't automatically mean they will raise the cholesterol levels in your blood. Cholesterol is also produced by the liver, so when you consume eggs, the liver will produce less cholesterol to even things out. What eggs will do is raise "good" cholesterol (HDL or high-density lipoprotein). The real culprits in sabotaging cholesterol levels are saturated fats and trans fats; eggs have very little of the former and none of the latter.
