BACKGROUND Few studies in recent years have demonstrated the effect of maternal diet on fatty acid composition of human milk. METHODS Fourteen free-living lactating women participated in a cross-over dietary intervention study, consuming a low fat diet (17.6% of energy as fat, 14.4% of energy as protein, 68.0% of energy as carbohydrate) and a high fat diet (40.3% of energy as fat, 14.4% of en...

Control and diabetic rats were fed on semi-purified high-fat diets providing a polyunsaturated/saturated fatty acid ratio (P/S) of 1.0 or 0.25, to examine the effect of diet on the fatty acid composition of major phospholipids of the adipocyte plasma membrane. Feeding the high-P/S diet (P/S = 1.0) compared with the low-P/S diet (P/S = 0.25) increased the content of polyunsaturated fatty acids i...

PURPOSE To investigate the fatty acid content of different fat sources and evaluate the effect of them on plasma and hepatic lipids and on the fatty acid profile of the brain tissue of Wistar rats. METHODS Thirty male albino Wistar rats received for 59 days, the following diets: diet added of margarine with low content of polyunsaturated fatty acids (PUFA); diet added of margarine with high c...

The present study was designed to examine whether the hipocholesterolemic effect of L-carnitine supplementation is related with lipoprotein fatty acid metabolism. Fatty acid compositional and cholesterol content changes were measured in lipoproteins of six different groups of rabbits. Group 1, rabbits fed a standard diet; group 2, rabbits fed standard diet plus L-carnitine 80 mg/kg bw; group 3,...

l- carnitine has been recognized as a new and important dietary supplementation, essential for human and animal nutrition. this study was conducted to evaluate the use of dietary l- carnitine supplementation and its effects on the growth (body final weight, daily growth rate (dgr), feed efficiency (fe), feed conversion ratio (fcr), daily feed intake  (dfi), protein efficiency ratio (per), lipid...

The fatty acid composition of lymphocytes, and other immune cells, is altered according to the fatty acid composition of the diet and this alters the capacity of those cells to produce eicosanoids, such as prostaglandin E2, which are involved in immune-regulation. A high fat diet can impair lymphocyte function. Cell culture and animal feeding studies indicate that oleic, linoleic, conjugated li...

The effects of eicosapentaenoic acid (EPA, n-3 polyunsaturated fatty acid) and linoleic acid (n-6 polyunsaturated fatty acid) on azoxymethane-induced colon carcinogenesis in rats were studied. Male Donryu rats were given two types of semipurified diet containing 4.7% EPA plus 0.3% linoleic acid and 5% linoleic acid. The rats were given s.c. injection of azoxymethane (7.4 mg/kg body weight once ...

The lipid compositions of whole brain homogenates and microsomal and myelin fractions isolated from the brains of 6-month-old rats raised on a lab chow diet, a fatty aciddeficient diet, and a deficient diet supplemented with 595 (w/w) corn oil were determined. Brain and body weights were significantly lower in the fatty acid-deficient group. The compositions of alk-1-enyl groups and phospholipi...

Dietary intake of whole grains reduces the incidence of chronic diseases such as obesity, diabetes, cardiovascular disease, and cancer. In an earlier study, we showed that Panicum miliaceum L. extract (PME) exhibited the highest anti-lipogenic activity in 3T3-L1 cells among extracts of nine different cereal grains tested. In this study, we hypothesized that PME in the diet would lead to weight ...

Milk production, milk composition, milk fatty acid profiles, and antioxidant status of Simmental cows supplemented with non-protected sunflower oil were studied. Ten Simmental cows in mid-lactation were appointed for change over feeding trial with one of the diet applied: the control (WSO) diet consisted of 26 % corn silage, 33 % perennial ryegrass haylage, and 41 % concentrate in dry matter (D...
