How many calories in milk?

Curious about how many calories are in milk? Cow’s milk, a nutrient-rich dairy beverage, varies in calories according to its fat content. Plain cow’s milk is available whole-fat (3.25% milk fat), 2% or reduced-fat, 1% or low-fat and skimmed or fat-free. According to the American Academy of Pediatrics, whole milk is appropriate for babies (after weaning) until 12 months of age. By age 2, all babies should be switched to 2% milk. After age 2 and beyond, through adulthood, 1% or skim milk is appropriate. Whole milk provides about 150 calories and 8 g fat per cup (over half of which or 5 g is in the form of saturated fat).  Reduced-fat or 2% milk provides 122 calories and 5 g total fat (3 g saturated fat). Low-fat or 1% milk offers about 102 calories and 3 g total fat per cup (2 g saturated fat) and the same serving size of skim milk provides the fewest calories, 86 and 0 g fat per cup.
