Immunoglobulin classes and nutritional factors in plasma and breast milk of lactating mothers in Nigeria.

Background: Breast milk is important for the overall well-being of infants. Although lactation is relatively robust in the face of poor nutrition, the implication of poor nutrition on non-nutritive factors in breast milk is inconclusive.

Objective: This study was designed to find associations between nutritional and immune factors in maternal blood and breast milk with the aim to improve the needed public and individual strategies for a healthy infant.
