Well sure, but just because that's what it's designed for doesn't mean it doesn't contain stuff that's good for us, else you could rule out lots of food. Obviously being designed to help a small calf grow it contains a lot of fat, so we tend to remove that.
you can get the stuff in it from other sources though. it's not as if milk is the only source of those nutrients. and it's not exactly full of them either it has very little and large amounts of milk isn't good for anyone.
do you know that milk contains pus?
"They even think the amount of somatic ‘pus’ cells allowed in milk in the EU is too restrictive.
In the UK, a third of all dairy cows have mastitis each year – a bacterial infection of the udders. Like us, cows produce pus when they are fighting infection. Pus is made up of white blood cells and dead cell tissue carried in a thin fluid. White ‘somatic’ cells are the immune system’s ‘soldiers’ sent to attack bacteria causing infection.
At the moment, the EU permits consumption of milk with up to 400,000 of these somatic pus cells per millilitre. Milk with a
somatic cell count of more than 400,000 is deemed unfit for human consumption by the European Union. This threshold is lower than the US requirement of 750,000 cells per millilitre. We don’t yet know what the British limit might be post-Brexit!
Average UK levels are around 200,000 pus cells per millilitre – that’s around one million cells in every teaspoonful of milk! Organic milk is no better – organic dairy farmers can’t use antibiotics to control the disease so the situation can be even worse."

so enjoy all that pus you are drinking in milk - disgusting
you may want to watch the food documentaries on netflix - they are eye openers to the meat and dairy industries. their budgets and times are so restrictive a lot of food and dairy is contaminated with faeces, blood, pus, etc.
there is a guy on a line whose job it is to burst the massive pus filled sacs on dead pigs. and you see the pus come squirting out everywhere.
