how many calories in 100 ml milk - #24873

I am really confused about my diet lately. I started drinking more milk, trying to be healthy and all, but I have no idea how many calories in 100 ml milk actually are. So, I've been tracking everything and I noticed that depending on the source, the calories info changes. Like, one site said it was around 60 calories, but another one mentioned 75. I mean, do different types of milk even count? I've switched between whole and skim milk to see what feels better for my stomach, but I’m not sure if the calorie count should be a concern if I’m just drinking like a small glass?? Sometimes, I mix it with smoothies too, or have it in tea, and I just wonder, does it add up quickly? Like, if I’m having a cup with my breakfast, would it make me over my daily limit? I’m just trying to balance everything, but I just don’t understand how to figure out how many calories in 100 ml milk is really gonna affect me. Any insights would be super helpful!
