BACKGROUND Breast milk is well established as the ideal source of nutrition for infants. Mature human breast milk generally contains 3.5-4.5% lipids comprising mostly triacylglycerols. In general, the fat composition of maternal human milk in developing countries shows higher levels of saturated fats, reflecting diets rich in carbohydrates. OBJECTIVES To(More)
Four commercial brands of infant milk formula were investigated, and the amount of shelf lipid peroxidation was determined by measuring malondialdehyde (MDA) or, more exactly, thiobarbituric acid reactive substance (TBARS) levels, which are the end products of lipid peroxidation. TBARS level, indicated by MDA concentration, was higher in the vegetarian(More)
We conducted this study to determine the fatty acid composition of breastmilk of Israeli women and compare it with baby milk substitutes. Samples of mature breast milk, from 29 lactating Israeli Jewish mothers were collected during feedings. Total milk lipids extracts were transmethylated and analyzed by using an improved gas-chromatographic method. About(More)
Shaven and unshaven rats were exposed to a cold stress at 4 degrees C for 6 hr (SE and UE). Control animals remained at room temperature (SC and UC). Hypothermia was induced in group SE, with mean rectal temperature of 22.0 +/- 2.0 degrees C (+/- S.E.M.). All other groups were normothermic, had similar arterial pO2 and hepatic tryptophan oxygenase levels.(More)
OBJECTIVES The aim of the study was to investigate whether lycopene from natural sources (tomato extract) is able to protect newborns milk formula, against oxidative damage caused by exposure to hydroxyl radicals, and is there a difference between milk substitutes from various sources. METHODS Four commercial brands of infant milk formula: two of the(More)
