Differences between polyunsaturated fatty acid status of non-institutionalized elderly women and younger controls: A bioconversion defect can be suspected

Article Abstract:

Elderly people may be nutritionally deficient due to inadequate food intake and digestive perturbations. Modifications in membrane lipid status have been noted in ageing populations, and the result is a change in membrane microviscosity and cell function. The plasma and erythrocyte fatty acid status in 200 women over 75 who live at home was compared with that of a control group of young female volunteers, with an emphasis on the essential fatty acids (EFA). Significant differences in the n-3, n-6 and n-7 FAs in elderly non-institutionalized women were found that relate to nutritional intakes.

Supplementation with wine phenolic compounds increases the antioxidant capacity of plasma and vitamin E of low-density lipoprotein without changing the lipoprotein Cusuper2+-oxidizability: Possible explanation by phenolic location

Article Abstract:

Oxidized low density lipoprotein (ox-LDL) is known to be important in atherogenesis. Phenolic compounds are found in dry extracts of red wine and have been shown to be strong reactive oxygen species scavengers. The effects of the red wine phenolic compound (RWPC) dietary supplementation without alcohol interference on the biochemical characteristics of LDL, the oxidative susceptibility of LDL and the antioxidant capacity of total plasma (Pl-AOC) were evaluated. The RWPC supplementation had an enhancing effect on P1-AOC which could be due to a phenolic compound action.

Effects of preterm infant formula supplementation with alpha-linolenic acid with a linoleate/alpha-linoleate ratio of 6: a multicentric study

Article Abstract:

The n-3 fatty acid status of premature infants can be maintained through supplementation of alpha-linolenic acid (ALA) in premature infant formula. Premature infants were fed either an ALA-supplemented formula or non-supplemented milk formula to study the effects of ALA on red blood cell and plasma fatty acids. Breast-fed infants were studied as a reference group. ALA supplementation had limited impact on the n-6 family of essential fatty acids.
