Unless you hang out exclusively with white people, there are a lot of people that thing drinking a glass of milk is weird, they just don’t tell you, because they’re polite.

Dairy “products” are a separate concern. Most people produce some level of lactase, but a glass of cow’s milk is a separate thing.

Aged cheese, for instance, is a different thing. Why would aging cheese add distinct flavors? Because bacteria is digesting the sugars (lact-OSE) and converting it into other things.

I love cabot cheddar myself for cheap stuff. If you want to know the lactose content of cheese or other dairy products, if there are no added sugars, just check the sugar content. That’s lactose. If it says zero, it’s near zero.

I’ve never met an adult in my life, of any color, that orders a glass of milk and drinks it. I’m sure it happens, but I guess just not in the circles I run in.
