I guess I feel like I'm stating the obvious, but it's higher in calories, fat, saturated fat, and cholesterol. But like a previous poster said, everything in moderation. I'm afraid most that drink whole milk don't also consume the amount of veggies you do.
"An 8-ounce glass of whole milk provides 149 calories, 8 grams of protein, 276 milligrams of calcium, 8 grams of fat, 4.5 grams of saturated fat and 24 milligrams of cholesterol. Low-fat milk delivers the same amount of protein and calcium, but in fewer calories: A cup of two-percent milk has 120 calories, 5 grams of fat, 3 grams of saturated fat and 20 milligrams of cholesterol."
