In what ways does breastmilk differ from formula nutritionally?
What will be an ideal response?
Answer: Breastmilk is not similar to animal milks-designed for human needs, proteins, fats, and CHO are mostly synthetized by breast tissue, proteins made by breast tissue less likely to cause reactions like other proteins (food allergies). Fat lipids in milk include: cholesterol, linoleic acid, omege-3 (DHA) for development, infants need to feed for 20 min to get kcals in fat-rich "hind" milk, carbohydrate-lactose primarily found in milk, galactose is made in breast tissue, glucose comes from mother's bloodstream. Nutrional qualities of infant formula-they can mimic but cannot be exactly replicated to breastmilk, cannot duplicate immunological protection provided. Carbohydrate-lactose and/or sucrose, Protein-modified protein from cow milk, soy, meat, soy based can be helpful for infants allergic to proteins in cow-milk, can be made for medical conditioins like PKU, Fat-vegetable oils.
