i've been told that in different countries the caps on the milk are different, for example here in Britain the cap for whole milk in blue, while in america it's red. assuming you're from america, i'm not to sure what an american equivalent is to semi skimmed, but from what i've seen i'm going to assume it's basically the same as both 1% and 2%. in regards to your next two questions the answer to both of them, is yes. i have always drank whole milk and have never drank anything else, even though my mum prefers semi skimmed and plagues my fridge. i believe my dad would make jokes about semi skimmed milk being worse, and being autistic, i took it seriously and have now developed the mentality that if my milk carton doesn't have a blue cap it is not worth drinking, and is disgusting.

nonfat is the most incorrect choice there is it's the complete opposite of whole milk, which in case you've forgotten is the best milk
