Answer :Just like regular milk, powdered or dry milk comes in different types. The most important difference is whether the milk is nonfat or whole. If youre reconstituting whole powdered milk, youre getting 159 calories and 5.3 grams of saturated fat from every quarter-cup of powder. But if you stick to nonfat dry milk, a quarter-cup of powder contains just 109 calories and only trace amounts of fat, while still containing 100 IU of vitamin D and 377 milligrams of calcium-amounts similar to ordinary skim milk. Mixing dry milk extra rich would indeed boost the nutrients (as well as the calories)-just make sure youre buying the nonfat variety, or it would truly be extra rich in fat and calories.
