I do not like to drink milk because I find that I gain too much flab.
Would it be OK if I had a couple of cans of pop a day instead?
Soft drinks may taste good but they are definitely not good for you. The sugar, caffeine and chemical additives contained in soft drinks can trigger weight gain (two cans of pop a day would add 110,000 calories a year and get you on the way to gaining a full 32 pounds!) also you run the risk of physical and mental dependency, dental decay and increased illness as you get older.
You cannot compare the nutritious value of milk and pop. Milk (especially raw milk) contains a little of almost every nutrient known to man. Soft drinks have no nutritional benefit at all.
