Milk is one of the most caloricly dense foods you can consume. Is that good or bad? Well, it depends.
Milk is very high in protein. A glass (250ml) of milk contains about 7.8g of high quality protein. It also has other stuff in it, like Lactose (about 12g per glass) and as we know, lactose is a sugar which in turn makes it a carbohydrate. It also contains about 8g of fat (whole milk). In short, milk is quite nutritious, which is no surprise,
as it evolved to make mammals grow.
For an active person who also does sports, those nutrients sure come in really handy. I lift heavy weights and have done so for several years now and milk is a great tool. It's cheap, it's handy, it's available anywhere, and it's (in my opinion) delicious. A liter of milk contains over 500 calories, and 32g of protein and 48g of carbs. As a post workout meal, there're few things more nourishing and refreshing than milk.Toss in a scoop of whey protein and you get almost 60g of protein that also taste like a milkshake. I can drink a whole liter out of the carton in less than 30 seconds. Sometimesm if I don't have time to get a proper meal, I just buy a liter of milk and chug it down. It sure beats eating junk food.
On the other hand, if you don't lift, and aren't particularly active, or if you'd like to have a six pack, I'd limit consumption to one glass per day.
Milk will make you fat if you are not careful. .
Lactose-free if you feel any discomfort after drinking it. Milk can also make you feel pretty groggy since it's so dense, so keep that in mind. I wouldn't drink it before having to do anything that requires your full attention.
Drinking milk regularly isn't that healthy. We kinda weren't built to do it after childhood.
I'd like you to elaborate exactly what's special about milk that forbids adults from consuming it. Sure, not everyone can digest lactose, specially not many adults. I'm lactose intolerant myself.
That's why I drink lactose free milk, which is ubiquitous, and which can be digested without issues. No milk farts from lactose-free milk, since the milk-farts are caused by bacteria in the gut which feast on the lingering lactose, producing methane.
Since lactose in lactose free milk has already been hydrolyzed into its component sugars (glucose and galactose) which are easily absorbed through the gut. , there's no risk of lactose being absorbed by gut bacteria.
Other than the lactose, there's nothing special about milk compared to other caloric-dense foods.
