Randomized Controlled Trial Pragmatic Clinical Trial
Addition of oat bran reduces HDL-C and does not potentialize effect of a low-calorie diet on remission of metabolic syndrome: A pragmatic, randomized, controlled, open-label nutritional trial.
It is unclear whether addition of soluble fiber to a low-calorie diet potentializes weight loss and amelioration of metabolic syndrome (MetS). The aim of this study was to analyze the effects of oat bran on prevalence of MetS and associated disorders. ⋯ Daily consumption of oat bran did not potentialize the beneficial effects of a traditional low-calorie diet on the prevalence of MetS and associated disorders. Additionally, it reduced HDL-C.

Randomized Controlled Trial
Differential plasma postprandial lipidomic responses to krill oil and fish oil supplementations in women: A randomized crossover study.
There is no convincing evidence that krill oil (KO) consumption results in a higher incorporation of long chain ω-3 polyunsaturated fatty acids into blood lipid fractions than fish oil (FO). This study examined the postprandial plasma lipidomic responses to KO supplementation compared with FO supplementation in healthy women. ⋯ After the supplementations, 5 out of 34 lipid classes or subclasses had significantly greater concentrations from KO compared with FO. There were 27 molecular species including 5 ether-phospholipid species, out of a total of 701, which had significant differences between supplementations in the postprandial period. Eicosapentaenoic acid and docosahexaenoic acid from KO were preferentially partitioned toward phospholipid molecular species, whereas eicosapentaenoic acid and docosahexaenoic acid from FO were preferentially partitioned toward neutral lipids.

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.
