Changing poor dietary habits is effective for treating metabolic syndrome (MetS). Despite the global reputation of the Mediterranean diet (MD) for health, research on its link to MetS is limited, especially in non-Mediterranean regions. This study aimed to investigate the relationship between the MD and MetS. Data from the 2007 to 2020 NHANES were analysed using multiple logistic regression, restricted cubic spline (RCS) regression, and subgroup analysis. Among 20,991 participants, a negative association between Mediterranean diet score (MDS) and MetS prevalence was observed. RCS regression indicated a linear relationship. Subgroup analysis revealed a significant negative association in most groups, except those with high school education, other Hispanics, and non-Hispanic blacks. In the American population, greater adherence to the Mediterranean diet is associated with a reduced risk of metabolic syndrome, emphasising its protective effects and relevance in public health strategies. Future research should focus on promoting its adoption and investigating causal mechanisms and the impact of specific dietary components through longitudinal studies.

Phosphatidylcholine (PC) has garnered considerable attention due to its involvement in a wide array of crucial biological functions. However, there is still much to active explore regarding the precise mechanisms that underlie PC's actions in the context of high-fat diet. In this study, we found that both PC intervention and treatment significantly mitigated lipid accumulation, liver damage, and body weight gaining triggered by the high-fat diet. Untargeted and targeted metabolomic analyses uncovered substantial effects of PC on bile acid metabolism, especially led to a substantial reduction in elevated levels of free bile acids. 16S rRNA gene sequencing revealed that PC modulated the gut microbiota structures and compositions in high-fat diet mice, particularly exhibiting a positive association with Pseudoflavonifractor abundance, and a negative correlation with Olsenella, Parasutterella, and Allobaculum abundance. Our study suggested that PC held promise as a potential candidate for alleviating lipid metabolism injury, liver disease or obesity.

A gluten-free diet is the only treatment for patients with coeliac disease, who report dissatisfaction with the availability and variety of products, especially bread and pasta. The aim was to compare availability, cost, nutritional composition and ingredients of gluten-free and conventional bread and pasta products. Census of breads and pastas available in online commerce belonging to the third largest supermarket chain in southern Brazil. Information was collected at supermarket's and brand's websites. One hundred and fourteen products were analysed (n = 37 breads and n = 77 pastas): 32.4% (n = 12) gluten-free breads and 18.2% (n = 14) gluten-free pastas. Both gluten-free breads and pastas were significantly more expensive when compared to gluten-containing breads and pastas. Gluten-free breads have higher fat content, gluten-free pastas have higher content of sodium and ingredients. Gluten-free breads and pastas are less available, more expensive and have lower nutritional value compared to conventional versions.

In this cross-sectional study, we explored the influence of Mediterranean Diet (MD) adherence and physical activity-related energy expenditure on weight status and cardiometabolic risk in a large sample of 2.833 young, middle-aged and older adults. A food frequency questionnaire was employed, and MD Score to assess MD adherence. Physical activity-related energy expenditure was reported through the Minnesota Leisure Time Physical Activity Questionnaire. Anthropometry, blood pressure, lipid and glycaemic markers were measured. Most of the participants were overweight or obese and had a medium-high MD adherence. The obesity group showed lower energy expenditure and a greater clustered cardiometabolic risk. Overweight and obese had a greater clustered cardiometabolic risk compared to the high MD adherence and normo-weight. Obese showed the greatest clustered cardiometabolic risk with independence of MD adherence. Increasing energy expenditure through physical activity better than restrictive diets might be one of the key components for reducing cardiometabolic risk among obese people.

Low-carbohydrate diets (LCD) have inconclusive impacts on psychological outcomes, quality of life (QoL), and cognition. This study summarised current evidence by searching PubMed/Medline, Scopus, and Web of Sciences until October 2024. Thirty randomised controlled trials (RCTs) were included with a total sample size of 1781 (923 in the LCD group and 853 in the control group). No significant effect of LCD on mood disturbance, depression, anxiety, QoL, or memory speed was found. Subgroup analysis, however, showed significant QoL improvement in subjects consuming ≥15% of energy from carbohydrate, and trials with follow-up over 120 days. Of note, LCD significantly increased QoL in patients with neurological disorders. However, an unfavourable decrease in memory speed was observed in adults older than 55 years, and those consuming ≥15% of energy from carbohydrate. Findings demonstrated contradictory effects of LCD on QoL, mood, mental health, and memory speed.

The objective was to examine the association between the intakes of whole grains, refined grains, and whole/refined ratio with periodontitis. Data from 7,753 adults participating in NHANES 2009-2014 were used. The intakes of whole grains, refined grains, and whole/refined ratio were collected and calculated. Periodontitis was defined according to the CDC. The relationship between periodontitis and grains intakes were evaluated by using multivariate models. Dose-response relationship was modelled by restricted cubic spline regression. In the fully adjusted model, the whole grains intake (Q4 ORs: 0.70 (0.56,0.89)) and whole/refined grain ratio (Q4 ORs: 0.75 (0.60,0.93)) were negatively associated with periodontitis. The results of restricted cubic spline regression showed an OR of 0.89 (95% CI: 0.84,0.95) for per 28.3 g/d increase in whole grain intake, and the whole/refined grain ratio had a J-shaped association with periodontitis. Increased intake of whole grains was associated with lower prevalence of periodontitis.

This study integrated analyses of gut microbiota and metabolomics to investigate the impact of ellagic acid (EA) on non-alcoholic fatty liver disease (NAFLD). Compared to the high-fructose diet (HFruD) group, the EA group exhibited reduced body weight and fat mass, alongside improvements in blood glucose and lipid metabolism. Liver metabolomics analysis revealed that EA increased the abundance of metabolites in pathways related to unsaturated fatty acids, amino acids and bile acids. Furthermore, EA induced alterations in the composition and structure of gut microbiota, notably decreasing bacterial genera enriched by HFruD while promoting beneficial bacteria such as Faecalibaculum. Correlation analysis demonstrated significant associations among NAFLD markers, gut microbiota and liver metabolites influenced by EA. This study provides new insights into the anti-NAFLD effects of EA, suggesting EA as a promising nutraceutical for improving NAFLD.

Climatic conditions, genotypes, and post-harvest processing methods influence coffee quality. Microbial fermentation during post-harvest processing has sparked researchers' interest due to the modulation of the sensory characteristics of coffee. However, the influence of microbial fermentation on different coffee genotypes has been little investigated. The objective of this study was to evaluate the chemical and sensory changes of Coffea arabica cultivars caused by different post-harvest processing and fermentations. Catucaí 785 and Catucaí Açú cultivars had better sensory evaluation than the Arara cultivar in the two years of sampling. However, dry fermentation proved to be a promising alternative to improve the sensory analysis of the Arara cultivar. Inoculation of Saccharomyces pastorianus yielded positive results in the chemical and sensory of the Catucaí Açú cultivar. Each coffee genotype is capable of expressing unique sensory and chemical attributes depending on the different post-harvest processing and fermentations applied.

Aims to find out how adding different amounts of hazelnut to corn flour affects women's blood glucose fluctuations. Women (n = 23) were given loaves of bread containing corn and hazelnut flour (50 g digestible CHO). They were given 50 g of glucose syrup to consume in the first week, normal corn-bread (CB) in the second week, 15 g of corn-bread with hazelnut flour (CB + 15HN) in the third week and 30 g of corn-bread with hazelnut flour (CB + 30HN) in the fourth week. Blood glucose was measured at 0, 15, 30, 30, 45, 60, 90, and 120 min. CB+HN15 AUC values were found to be significantly lower compared to the other breads (p < 0.05). In addition, The GI of CB+HN15 was significantly lower than the GI of the other two breads (p < 0.05). The positive effect on blood glucose fluctuations started to decrease when the addition of hazelnut flour was more than 15 g.
