People of European decent tend to be much better at digesting milk (lactose) as adults and there's a meme that if you can't chug a bottle of milk you have to get out. Or something silly like that. Turns out groups of people with ancestry in east Africa have the gene for lactose as well.
So, milk could become a symbol of this if used within that context. People are paranoid enough today that if a picture of someone enjoying a glass of a milk was published, they could assume it was a signal of this. And it could be, to be sure.
