Comparison of Potential Renal Solute Load (PRSL) in healthy breastfed and non breastfed infants.
Esculapio J Services Inst Med Sci Jan ;3(4):14-20.

Background: In our society due to some social and cultural beliefs many mothers deprive their infants from the benefits of breast feeding. The infants are fed cow milk/buffalo milk purchased from the market. The infant formula milk is very costly and it is not possible for an average family to afford formula milk for an infant. The milk of cows and buffalos is having three times more proteins and 3-4 times more minerals as compared to the human milk. By feeding the milk of cow or buffalo/infant formula, the infant is being loaded with more proteins and minerals, which can lead to high PRSL and high concentration of serum minerals. Study Design: This is a descriptive and cross-sectional study which has been conducted on infants up to the age of 6 months being fed either mothers` milk, infant formula or cow/buffalo milk. Sample Size: A total sample of one hundred and fifty infants up to the age of 6 months was selected. The sample was divided into three groups of fifty infants in each group. Place of Study: The study was conducted in outpatient department of the Children`s Hospital & the Institute of Child Health, Lahore after due permission from concerned authorities. Results: The serum levels of BUN, urea, sodium, potassium, phosphorus, chloride and PRSL were all significantly low in breast-fed infants as compared to the infants on bottle feeding taking infant formula or cow/buffalo milk. Conclusion: The present study has clearly highlighted that “Mother`s Milk is the best milk”. By feeding the milk of cow or buffalo/infant formula, the infant is loaded with more proteins and minerals, which can lead to high PRSL and high concentration of serum minerals. The effects of these components may not be visible immediately but may have consequences in later life.
