Views on drinking milk generally falls into 2 camps:

Can assume carbohydrate content equivalent to sugar.... naturally occuring sugar (lactose)

It's a staple in some countries. 'The 2007 milk consumption per capita in Finland was 361.19kgs, with milk consumption per person at about 34.34 gallons per year.' https://www.worldatlas.com/articles/countri...-most-milk.html
That makes it 356ml daily per person (inclusive of dairy products).

My take on it (for now)... Milk contains a good source of calcium and protein. Consume it in moderation.
