Constituents of breast milk Essay Cholesterol enhances myelinization of nervous tissue Choline Memory enhancement Docsohexanoic acid necessary for growth and development of the brain and retina, also for myelinization of nervous tissue Enzymes such as lipases Helps in digestion of fats Glutathione peroxidase, alkaline phosphatase, xanthine oxidase important in prevention of infection Inositol enhances synthesis of surfactant in immature lung tissue Lactoferrin binds iron and transports it efficiently into the baby; prevents iron from being used by gut bacteria. Lactoferrin (above), lysozyme, secretory immunoglobulin A line intestinal surface, prevent bacterial attachment and infection Nucleotides building blocks of DNA, RNA, and energy storage compounds; enhance formation of immunity to infection Poly- and oligo-saccharides block bacterial binding to intestinal surfaces Proteins There are receptor proteins and binding protein, bind calcium and zinc for absorption by the baby; supply amino acids to the baby White blood cells Help protect infant from bacteria and foreign body invasion.

Formula milk Several studies have shown that human milk is much more nutritious and healthy for infants as compared to any man made formulas. Boyd (et al, 2006) also found that breast milk from donors reduces the risk of necrotising enterocolitis. In another study the fat globule size in the mother’s milk colostrums is adequate and large for better absorption as compared to formula milk and adult human milk (Michalski et al 2005). COMPARISON OF HUMAN MILK AND FORMULA. NUTRIENT FACTOR BREAST MILK CONTAINS FORMULA CONTAINS COMMENT Fats †¢ Rich in brain-building omega 3s, namely DHA and AA -Automatically adjusts to infants needs; levels decline as baby gets older -Rich in cholesterol -Nearly completely absorbed -Contains fat-digesting enzyme, lipase -No DHA -Doesnt adjust to infants needs -No cholesterol -Not completely absorbed -No lipase Fat is the most important nutrient in breastmilk; the absence of cholesterol and DHA, vital nutrients for growing brains and bodies, may predispose a child to adult heart and central nervous system diseases. Leftover, unabsorbed fat accounts for unpleasant smelling stools in formula-fed babies. Protein -Soft, easily-digestible whey -More completely absorbed; higher in the milk of mothers who deliver preterm -Lactoferrin for intestinal health -Lysozyme, an antimicrobial -Rich in brain-and-body- building protein components -Rich in growth factors -Contains sleep-inducing proteins -Harder-to-digest casein curds -Not completely absorbed, more waste, harder on kidneys -No lactoferrin, or only a trace -No lysozyme -Deficient or low in some brain-and body-building proteins -Deficient in growth factors. -Does not contain as many sleep-inducing proteins. Infants arent allergic to human milk protein. Carbohdrates -Rich in lactose -Rich in oligosaccharides, which promote intestinal health -No lactose in some formulas -Deficient in oligosaccharides Lactose is considered an important carbohydrate for brain development. Studies show the level of lactose in the milk of a species correlates with the size of the brain of that species. Immune Boosters -Rich in living white blood cells, millions per feeding -Rich in immunoglobulins -No live white blood cells-or any other cells. Dead food has less immunological benefit. -Few immunoglobulins and most are the wrong kind When mother is exposed to a germ, she makes antibodies to that germ and gives these antibodies to her infant via her milk. Vitamins and Minerals -Better absorbed, especially iron, zinc, and calcium -Iron is 50 to 75 percent absorbed. -Contains more selenium (an antioxidant) -Not absorbed as well -Iron is 5 to 10 percent absorbed -Contains less selenium (an antioxidant) Vitamins and minerals in breast milk enjoy a higher bioavailability-that is, a greater percentage is absorbed. To compensate, more is added to formula, which makes it harder to digest. Enzymes and Hormones -Rich in digestive enzymes, such as lipase and amylase -Rich in many hormones: thyroid, prolactin, oxytocin, and more than fifteen others -Varies with mothers diet -Processing kills digestive enzymes -Processing kills hormones, which are not human to begin with -Always tastes the same Digestive enzymes promote intestinal health. Hormones contribute to the overall biochemical balance and well- being of baby. By taking on the flavor of mothers diet, breastmilk shapes the tastes of the child to family foods. Cost -Around $600 a year in extra food for mother -Around $1,200 a year -Up to $2,500 a year for hypoallergenic formulas -Cost for bottles and other supplies -Lost income when baby is ill Retrieved from http://www. askdrsears. com/html/2/T021600. asp.
