Drinking large amount of

Hi , it has been a long time since i started eating big on breakfast.
Now i dont have really to much time to cook so i found milk + some carb variety to be a good breakfast.
I drink in the morning at least 500 ml of milk + fruit + some wheat derivate .To say the truth i am a milk lover ..
and i drink about 1L of milk /day..
Now, some people told to me that it is not good to drink such amount of milk ,because u can become milk intolerant ....
Is this true ?Is it good to drink 1 Liter a day ..?? Can milk cause any harm ??
Best Regards

Some people drink milk all they want with no problems and others cannot. As we get older there is a greater chance of a decrease of the enzyme lactase in the stomach (breaks down the sugar in milk) which you may become intolerant to milk in different degrees.
