Is it true that milk stored in plastic is not as healthy as milk in cardboard containers due to radiation?
Probably. HDPE (high density polyethylene) allows blue and ultraviolet light to strike the milk, degrading some of its nutrient molecules. It isn't radiation from the plastic but rather the sunlight that the plastic doesn't keep out of the milk. Adding an absorbing chemical to the plastic would help, but it would create an amber plastic (like amber medicine bottles; which are colored for this same reasons). If we could get used to having amber plastic, we would probably be better off. However, people seem to tolerate amber orange juice jugs but not amber milk jugs.
