Dairy fat blends high in α-linolenic acid are superior to n-3 fatty-acid-enriched palm oil blends for increasing DHA levels in the brains of young rats.

Achieving an appropriate docosahexaenoic acid (DHA) status in the neonatal brain is an important goal of neonatal nutrition. We evaluated how different dietary fat matrices improved DHA content in the brains of both male and female rats. Forty rats of each gender were born from dams fed over gestation and lactation with a low α-linolenic acid (ALA) diet (0.

1H NMR metabonomics can differentiate the early atherogenic effect of dairy products in hyperlipidemic hamsters.

Diet is an important environmental factor modulating the onset of atherosclerosis. The aim of this study was to evaluate the effects of different dairy-based food products on early atherogenesis using both conventional and metabonomic approaches in hyperlipidemic hamsters. The hamsters received up to 200 g/kg of fat as anhydrous butter or cheese made from various milk fats or canola-based oil (CV), in addition to a non-atherogenic low-fat diet.

Threshold to N-methyl-D-aspartate-induced seizures in mice undergoing chronic nutritional magnesium deprivation is lowered in a way partly responsive to acute magnesium and antioxidant administrations.

Magnesium deficiency may be induced by a diet impoverished in magnesium. This nutritional deficit promotes chronic inflammatory and oxidative stresses, hyperexcitability and, in mice, susceptibility to audiogenic seizures. Potentiation by low-magnesium concentrations of the opening of N-methyl-D-aspartate (NMDA) receptor/calcium channel in in vitro and ex vivo studies, and responsiveness to magnesium of in vivo brain injury states are now well established.
