Over the years I have learnt myself that milk has been something very difficult to digest. On a recent scan I've also been advised that I am slightly lactose intolerant (not sure what the slighty means to be honest).
Few years ago I started to only have hot chocolate with soy milk (I'm not sure it's the best alternative) but it is definitely much better! For many years my breakfast would be hot chocolate and I would always be bloated, but nobody had ever questioned my diet! I guess things have changed a lot nowadays with people more and more aware about what they consume.

Saying all that Guilly used to drink milk instead of water (I know what?!) and when he stopped he significantly dropped weight and was digesting much better. So I'm convinced straight milk isn't good for adults.

I was told though that while Milk isn't good for you cheese - yogurt are good products / there are a lot of different contradictory information being shared online. What's your view @flamingirl on yogurt and cheese (especially for a french person :-p).
