High cholesterol causes cardiovascular disease. Eggs are high in cholesterol; a large egg contains about 210mg of the stuff, which is concentrated in the yolk.

However, according to a new study in the journal Pediatrics, only 25% of them will be appropriately shielded from the sun’s harmful ultraviolet rays [1]. This is down from 50% of children who reported using sunscreen “often or always” in 2004.
