In expressing milk, which statement BEST describes the difference between foremilk and hindmilk?

• A. The fat content is up to 3x greater in hindmilk than foremilk
• B. Foremilk contains more fat than hindmilk
• C. Hindmilk contains more lactose but less fat
• D. Foremilk and hindmilk have identical fat content

Answer: (A)

During a single breastfeeding session, milk composition shifts from the initial foremilk to the later hindmilk. Foremilk is the thinner, early milk that provides hydration and more lactose, while hindmilk appears creamier and has a higher fat content, delivering more calories. The statement that best describes this difference is that fat content is up to three times greater in hindmilk than in foremilk. This captures the main point—that hindmilk is richer in fat, though the exact amount varies from feeding to feeding and among individuals. The other ideas don’t fit the pattern: foremilk is not higher in fat than hindmilk, hindmilk is not richer in lactose with less fat, and foremilk and hindmilk do not have identical fat levels. In practice, ensuring a full feeding helps the infant receive the fatty, energy-dense hindmilk. When expressing milk, note that the early expressed milk is foremilk and the later portions are more likely to be hindmilk.
