Reduced-fat milk is labeled as 2 percent milk, which means the milkfat is 2 percent of the total weight of the milk — not that an 8-ounce glass of milk contains 2 percent fat. Here’s a nutrition fact to consider: An 8-ounce glass of 2 percent milk contains 5 grams of fat and has the same nine essential nutrients as every other type of milk. Please note the milk brand may vary based on availability.
