Soybean flour induces a greater increase of the antioxidant defenses in rats fed with a normocaloric diet compared with a hypercaloric diet.

Background: Soybeans, due to their antioxidant properties, present beneficial health effects. The objective was to evaluate if replacing casein with soy flour, modifies antioxidant defenses in rat liver, compared to animals that continued being fed with casein based diets (normocaloric and hypercaloric).

Results: Four groups of rats were used: CC (control casein), CS (control soy), HC (hypercaloric casein) and HS (hypercaloric soy).

Biochemical and molecular study of the influence of Amaranthus hypochondriacus flour on serum and liver lipids in rats treated with ethanol.

Hyperlipidemia and hepatic steatosis are frequent alterations due to alcohol abuse. Amaranth is a pseudocereal with hypolipidemic potential among other nutraceutical actions. Here we study the effect of Amaranthus hypochondriacus (Ah) seeds on serum and liver lipids, and the expression of genes associated to lipid metabolism and liver histology in male Wistar rats intoxicated with ethanol.

Antioxidant properties of Amaranthus hypochondriacus seeds and their effect on the liver of alcohol-treated rats.

Amaranth constitutes a valuable pseudocereal, due to its nutritional quality and its nutraceutical properties, which contribute to improve human health. This work evaluated the effect of a diet based on Amaranthus hypochondriacus (Ah) seed on oxidative stress and antioxidant status in the liver of rats sub-chronically exposed to ethanol. The seed extract was investigated for antioxidant capacity in vitro, showing an adequate content of total phenols and antioxidant activity elevated.
