Intermittent fasting (IF) is a nutritional intervention with significant metabolic effects on the liver that are not yet fully understood. The aim of this study was to investigate the effects of IF on body mass, lipid profile, glucose metabolism, liver lipogenesis, β-oxidation, and inflammation. ⋯ There were beneficial effects of IF even with the continuity of the obesogenic diet and proinflammatory diet in mice. It is recommended that based on the beneficial effects of IF on glucose and liver metabolism and inflammation that IF be a coadjutant factor in the treatment of hepatic metabolic issues and steatosis.

Dyslipidemia is an important risk factor for cardiovascular diseases. Fucoidan (FUC) is a polysaccharide extracted from brown marine algae with various biological activities. Galactooligosaccharides (GOS) are important prebiotics that exert benefits on the intestinal microbiota. The aim of this study was to investigate the effects of FUC and GOS on dyslipidemia in rats by modulating the gut microbiota and bile acid metabolism. ⋯ In rats, FUC and GOS supplementation improved serum dyslipidemia, gut microbiota, BSH activity, and bile acid metabolism-related pathways. In vitro, GOS and FUC supplementation increased L. casei DM8121's BSH activity.

Dietary intake of vegetables is one of the key lifestyle factors associated with preventing cancer and cardiovascular disease (CVD). Although previous studies have provided evidence that dietary factors can alter global DNA methylation levels in humans, little work has been done on dietary factors influencing methylation levels of specific genes associated with CVD. The aim of this study was to examine whether dietary intake of vegetables was associated with adenosine triphosphate-binding membrane cassette transporter A1 (ABCA1) DNA methylation levels in leukocytes in a Japanese population. ⋯ High dietary intake of vegetables was associated with decreased ABCA1 DNA methylation levels in Japanese women. This may contribute to a better understanding of the protective effects of dietary vegetable intake on CVD.

The aim of this study was to investigate nutritional status in older patients undergoing maintenance hemodialysis (MHD) to determine the prevalence of nutritional markers indicating protein-energy wasting (PEW) as assessed by subjective global assessment (SGA) and other methods, and to explore which nutritional markers can best predict clinical outcomes. ⋯ Among older MHD patients, the prevalence of nutritional markers indicating PEW varies substantially depending on methods applied. SGA, MIS, BMI, GNRI, calf circumference, and HGS predicted worse outcomes. SGA and MIS showed the strongest association with hospitalization and mortality risk in the adjusted models.

Although glutamine and alanine have properties that could delay fatigue, recent evidence showed that these amino acids impaired central fatigue markers. Nevertheless, the effect of this intervention on muscle fatigue is unknown. The aim of this study was to investigate the effects of glutamine and alanine supplementation on muscle fatigue parameters in rats submitted to resistance training (RT). ⋯ Glutamine and alanine supplementation improved muscle fatigue markers without affecting exercise performance.
