“…The mean fat contents at OGT30 were close to those reported by Rona et al 35 and Aksit et al 36 , who studied the fat composition of human milk by creamatocrit. Variation of the total fat content of the milk of the study group OG during the lactating period was similar to those found by other studies 36,37 , showing that fat content decreases over time, possibly because of a reduction in the maternal fat reserves 24 .…”

Supplementation with the omega-3 docosahexaenoic acid: influence on the lipid composition and fatty acid profile of human milk

et al. 2013

OBJECTIVE: This study assessed the impact of supplementing the diet of women during pregnancy and lactation with fish oil containing the omega-3 fatty acid docosahexaenoic acid, and its influence on the composition of human milk. METHODS: The sample comprised 60 women aged 18 to 38 years with appropriate dietary pattern, all of them healthy and nonsmokers. The intervention consisted of a daily supplementation with fish oil capsules that corresponded to a daily intake of 315mg of docosahexaenoic acid and 80mg of eicosapentaenoic acid during the third trimester of pregnancy and the first three months postpartum. The total fat content and fatty acid profile of their milk were determined by creamatocrit and gas chromatography. Descriptive statistics were used for data analysis and the significance level was set at p<0.05. RESULTS: There was no statistical difference between the fat contents of the study (fish oil capsules) and control (capsules containing corn starch as filler) groups. However, the milk of women taking fish oil contained higher docosahexaenoic and eicosapentaenoic acid levels 30 and 60 days after delivery. These results demonstrate that high omega-3 intake can influence its concentration in human milk. CONCLUSIONS: Given the importance of docosahexaenoic acid in the neonatal period, it is appropriate for pregnant and breastfeeding women to supplement on long-chain polyunsaturated fatty acids, which may be done by adding fish oil to the regular diet.

“…The acidity developed is due to the lactic acid which is produced from the bacterial growth related to external contamination, such as contaminated hands and tools [10,13]. In addition to raising the acidity of HM, the production of lactic acid contributes to the non-absorption of calcium and phosphorus [13,20,21]. Despite the increase in the acidity of human milk, by being exposed to the environment after extracted, is considered as quality value ≤8 by the Dornic Method [10].…”

Objective To evaluate the quality of raw human milk distributed in the Neonatal Intensive Care Unit of a University Hospital of the city of São Paulo. Methods A cross-sectional study with raw human milk samples from mothers who attended the Human Milk Collection Station of a University Hospital, analyzed between May 2016 and January 2017, excluding mothers of twins. The quality of the raw human milk was assessed by verifying the presence of dirt, the coloration of the milk, the titratable acidity using the Dornic method, and through its energy content. Kruskal-Wallis and Mann-Whitney tests were used for the analysis of the energy profile and the degree of Dornic acidity, according to the stage of the raw human milk and the gestational age of the child. Results The study was composed of 40 samples of 40 different women, with a mean age of 27 years, an average of 11.8 years of education, most of them were multiparous and with a partner. Regarding milk analysis, 55.0% was classified as colostrum, 27.5% as mature milk and 17.5% as transitional milk. All samples presented negative results for dirt and normal coloration. The mean milk acidity was 3.24º Dornic and most of the samples were classified as hypercaloric energy content. There was no association between the lactation stage and gestational age with the acidity value and energy content. Conclusion The quality of raw human milk distributed in the Neonatal Intensive Care Unit of the institution evaluated was considered adequate and the samples analyzed had a high energy content and excellent Dornic acidity.

“…18 Therefore, it is important to know if there was bacterial growth prior to this processing, as that produces fermentation and acidification of the milk, which in turn lead to a reduction in nutritional and immunological components inherent to the food, disqualifying its use. 12,13,19 Acidified HM cannot meet the specific nutritional needs of very-low birth weight or immunologically-vulnerable preterm infants. The high acidity and the release of protons originating from the ionization of lactic acid in an aqueous medium cause destabilization of soluble proteins and casein micelles, favoring its coagulation; increase the osmolarity; alter the flavor (taste and smell); and reduce the immunological value of the food.…”

“…28 Many studies on HM supplementation for preterm infants with bone mineralization deficits have been developed to demonstrate the consequences of this conduct for this specific population. 6,8,9,19 However, the results are still conflicting, sometimes showing benefits for mineralization, sometimes showing no significant responses when compared to HM without supplementation and/or specific formulas for preterm infants. However, it must be considered that the methodologies used to assess these outcomes are quite diverse ---ranging from the ''classic'' investigation based on anthropometric data, X-rays, and serum biochemical analysis of calcium, phosphorus, alkaline phosphatase, parathyroid hormone, vitamin D metabolites, calcium, and phosphorus in urine; or more recently, by DEXA ---making it difficult to compare the findings.…”
