Orange Juice vs. Milk

  My parents and I disagree over whether I should drink Kroger 2% Milk versus Florida's Natural Orange Juice with Vitamin D and Calcium. I say that orange juice has the same amount of Vitamin D, more Vitamin C, calcium, thiamin, and folate acid, and therefore it would be a healthier choice to drink with dinner. Also, I flat out HATE the taste of milk. My only concerns that I have about this idea is the acid's affect on my teeth (I am supposed to brush after dinner anyways so this shouldn't be too big of a deal), orange juice's lack of protein (I get enough complete proteins as is, so again not a big concern), and the lower amount of Vitamin A.

  My parents, on the other hand, say that  milk has 'better types of fat' (I am confused about this one), has more protein, is 'nature's nuturing drink', and best of all and my favorite, is 'not a conventional drink to have with dinner'. Also, they say it is better for me and my metabolism if I consume more fats than sugars. I don't get this because I am very active, take in about 4000-5000 calories a day, and am constantly burning off energy and eating.

  My question for you is: Given the nutritional contents of both of these items, would it be a better choice for me to drink milk or orange juice with dinner?
