Why do nutritionists recommend dairy?

Milk is a good source of calcium. As babies we need milk. When we're older we are already accustomed to the taste. Most people like milk, coffee with creamer, cheeses, yogurts whether plain or with fruit. And ice cream is a big favorite. How would nutritionists convince kids to eat their chick peas or lettuce? I think it's easier for moms and dads to get their kids enough calcium by feeding them a variety of dairy products, most of which taste good.For those of us who are grown up, I guess we can decide for our self. I'm not sure what whey protein does or why it's being touted by doctors instead of other protein-rich sources. I think they should be telling people to use low-fat products instead of full fat. We still need some fat in our diets, but should keep it to a minimum. A balanced diet would be my recommendation; enough of fruits, veggies and dairy products. A little meat, and mostly whole wheat foods, or unprocessed foods. Avoid refined foods as much as possible.
