Jaboticaba peel powder and jaboticaba peel aqueous extract reduces obesity, insulin resistance and hepatic fat accumulation in rats.

This study investigated the effects of freeze-dried jaboticaba peel (FJP) and jaboticaba tea (JE) on obesity parameters of diet-induced obese rats. Thirty-six male Wistar rats were distributed into six groups: AIN-93 M feed a normal control diet; HFF (obese control) feed a high-fat and fructose diet; Prevention FJP (P. FJP) and Treatment FJP (T.

Antioxidant potential of dietary chia seed and oil (Salvia hispanica L.) in diet-induced obese rats.

This study aimed to investigate the effects of dietary chia seed and oil on plasma and liver oxidative status in diet-induced obese rats. Thirty-six Wistar rats were divided in six groups (6 animals each): control group was fed the American Institute of Nutrition (AIN)-93M diet; HFF group was fed a high-fat and high-fructose (HFF) diet; chia seed short (6-weeks) and long (12-weeks) treatments received an HFF diet with chia seed; chia oil short (6-weeks) and long (12-weeks) treatments received an HFF diet with chia oil. Plasma and hepatic biomarkers of lipid peroxidation, endogenous enzymatic and non-enzymatic antioxidant systems and antioxidant capacity were determined.

Chia (Salvia hispanica L.) enhances HSP, PGC-1α expressions and improves glucose tolerance in diet-induced obese rats.

Objective: The aim of this study was to investigate the effects of chia seed and chia oil on heat shock protein (HSP) and related parameters in diet-induced obese rats.

Methods: Animals were divided in six groups: control, high-fat and high-fructose diet (HFF), and HFF with chia seed or chia oil in short (6-wk) and long (12-wk) treatments. Plasma indicators of glucose tolerance and liver damage, skeletal muscle expression of antioxidant enzymes, and proteins controlling oxidative energy metabolism were determined.

Sorghum flour fractions: correlations among polysaccharides, phenolic compounds, antioxidant activity and glycemic index.

Nutrients composition, phenolic compounds, antioxidant activity and estimated glycemic index (EGI) were evaluated in sorghum bran (SB) and decorticated sorghum flour (DSF), obtained by a rice-polisher, as well as whole sorghum flour (WSF). Correlation between EGI and the studied parameters were determined. SB presented the highest protein, lipid, ash, β-glucan, total and insoluble dietary fiber contents; and the lowest non-resistant and total starch contents.
