Which statement accurately describes the relationship between maternal cholesterol intake and infant serum cholesterol values?

• A. Breastfed infants have lower serum cholesterol levels than those who are not breastfed.
• B. That maternal dietary cholesterol intake does not affect the infant's serum cholesterol values.
• C. Maternal cholesterol levels affect the cardiovascular risk of breastfed babies.
• D. She should limit her dietary cholesterol to prevent hyperlipidemia in her infant.

Answer: (B)

The main idea is that what the mother eats in terms cholesterol does not determine the baby’s serum cholesterol. Although cholesterol can cross the placenta, the fetus relies largely on its own cholesterol synthesis, and after birth the infant’s liver and tissues regulate cholesterol tightly. Breast milk provides cholesterol too, but it doesn’t meaningfully alter the infant’s serum cholesterol values. So maternal dietary cholesterol intake generally doesn’t impact the baby’s cholesterol levels, which is why that statement is the best description. The other options imply direct effects or risks that aren’t supported by the evidence, such as breastfeeding status lowering cholesterol, maternal levels altering the infant’s cardiovascular risk, or the need to limit maternal cholesterol to prevent infant hyperlipidemia.
