Abstract:

In this research 20 specimen from human whole milk and whey were studied with respect to lipoproteins, cholesterol and triglycerides, 2-8 months after parturition. The whey was separated by means of ultracentri fugation. Also the 24 hour diet history was recorded. The average lipoprotein components in normal human milk were, chylomicron 16.19%±11.98%, beta lipoprotein 36.71%±9.33%, pre beta-lipoprotein 8.61%±3.03% and alpha lipoprotein 38.49%±9.97%. These components were also measured in whey and the results were as follows: chylomicron 6.91%±1.55%, beta lipoprotein 47.32%±10.5%, pre beta lipoprotein 11.48%±4.4% and alpha lipoprotein 33.87%±7.84%. The percent average of the total lipoprotein content and its free forms were estimated in human milk. The average percent chylomicron content was 6.48%±1.43%, beta lipoprotein 33.85%±13.1%, pre beta lipoprotein 12.88%±2.78% and alpha lipoprotein was 47.25%±10.63%. The average ratio of alpha to beta lipoprotein (HDL/LDL) in human milk was found to be 1.10±0.51. Thus, we conclude that breast-feeding can be considered as a potential preventive factor against future cardiovascular diseases.
