Sahu, Devesh Tewari","doi":"10.3390/dietetics1030017","DOIUrl":"https://doi.org/10.3390/dietetics1030017","url":null,"abstract":"Colorectal cancer (CRC) is an abnormal growth that occurs in the rectum or rectal portion. In 2020, an anticipated 104,610 new cases of colon illness and 43,340 new cases of rectal abnormal growth were expected in the United States. Red and processed meat, body bloatedness, belly fatness, and binge drinking expands the occurrence of colorectal disease. Dietary fibres contribute to faecal bulking, but they are break down by gut bacteria and produce metabolites such as short-chain fatty acids (SCFAs). SCFAs are chemical compounds that are mostly made up of acetate, propionate, and butyrate. Acetate and butyrate help to control mucus production and discharge, and thus, protect the gut mucosa. Reduced mucus secretion/increased bacterial catabolism, and fermentation of amino acids resulted in an increase of potentially detrimental metabolites such as branched-chain fatty acids, ammonia, amines, and N-nitroso complex components. Vital roles of fibres include reduction in the time that carcinogens encounter the intestinal lumen and promotion of healthy gut microbiota as well as modification of the host metabolism. The present review focuses on a brief introduction to various dietary fibres and specialised metabolites that can possess beneficial effect on CRC, as well as presenting our current, detailed understanding of various dietary fibres along with their potential effects on gut microbiota and its association with the colon cancer. A comprehensive discussion is also included, advocating the dietary fibre-enriched diet.","PeriodicalId":72810,"journal":{"name":"Dietetics (Basel, Switzerland)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45071436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Pre-Conceptual Guidelines for Men: A Review of Male Infertility Experience, including Nutrition and Lifestyle Factors","authors":"J. Bold, David Swinburne","doi":"10.3390/dietetics1030016","DOIUrl":"https://doi.org/10.3390/dietetics1030016","url":null,"abstract":"Male fertility is declining and affects approximately one in seven couples. Reasons for this are multi-factorial and the subject of on-going research, though environmental contaminants (such xenoestrogens) are believed to be contributory factors. Semen parameters can be improved through a healthy diet and nutritional supplementation has also been shown to improve semen parameters, clinical pregnancy and live birth rates significantly. Despite this, in medical care dietary modification beyond alcohol reduction is rarely recommended. The aim of this review was to consider the psychosocial impacts of infertility in males whilst assessing other nutritional and lifestyle interventions that can be used in personalized nutrition care. More tailored nutrition care needs to consider this and the taboo surrounding the male infertility experience. A systematic approach was used. Three electronic databases (CINAHL, Medline and Academic Search Complete) were searched using predetermined Boolean search terms and identified 125 papers for review. Hand searches were undertaken to ensure recent evidence was included. Duplicates were removed and predefined inclusion and exclusion criteria were applied. Narrative synthesis was used for review and to develop preconceptual guidelines. Review data indicates dietary modification or supplementation with antioxidants such as vitamin C, vitamin E, coenzyme Q10, selenium, carnitine and zinc have been shown to improve markers of male fertility and reduce markers of seminal oxidative damage. Also, a Mediterranean style diet is also associated with higher quality sperm counts. Weight loss is beneficial in terms of normalizing endocrine profiles but at present it is not possible to determine if this is the effect of weight loss alone, or the combined effect of weight loss alongside other dietary improvement. Further research is therefore needed to understand the role of the many potential confounding factors. Despite this, infertility is emotionally challenging for men and nutrition, and personalised nutrition and lifestyle therapies have potential to support men trying to conceive. Pre-conceptual nutrition and lifestyle guidelines for men have been developed from this review and the use should be considered as the basis for more tailored nutrition care in practice.","PeriodicalId":72810,"journal":{"name":"Dietetics (Basel, Switzerland)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47742219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to use rule-developing experimentation (RDE) to identify consumer mindsets related to dietary sugars in 18–50-year-old Canadians. Following an isomorphic permuted experimental design, participants (n = 269) each rated a unique set of 24 scenarios, each consisting of a distinct mixture of two to four messages about dietary sugars on a 5-point scale. A regression model was created for each respondent, identifying the value that each respondent attributed to each of the 16 messages. K-means clustering revealed three distinct mindset groups as follows: “Sugars Beliefs” (MS1), “Trend Analysts” (MS2), and “Health Seekers” (MS3). In conclusion, this study found that RDE is a useful methodological approach for evaluating how consumers think about dietary sugars and revealed mindset-specific messages that matter most to people who differ in their attitudes toward sugars.","PeriodicalId":72810,"journal":{"name":"Dietetics (Basel, Switzerland)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41820294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Knowledge of the MDP score, attitudes towards the MDP score and an adherence to the MPD score were measured. Normality of variables was tested. Simple linear regression and Chi-squared tests were conducted to examine associations. ANOVA tests were used to report participants’ demographics across various attitudes scores. Less than half of participants were aware of the MDP guidelines, food choices and health benefits. As for adherence to the MDP, 20% of the sample were found to have high adherence to the MDP. Results also showed that participants with high knowledge about the MDP were twice more likely to have higher MDP adherence rates, OR 95% CI = 2.3 (1.3, 4.0), p-value = 0.002.

Given that many supplements may be ineffective and/or associated with adverse events, compliance of the registered trials to the European Medicines Agency (EMA) rule for prompt reporting of the results is of crucial importance for consumers’ health. The present retrospective study was designed to evaluate compliance with the European Union (EU) requirement to post the trial results to the EU Clinical Trials Database (EudraCT) and assess the trial characteristics associated with this compliance. Three independent researchers searched the EudraCT for completed trials on vitamin supplements performed on humans. A total of 144 completed trials involving 40,464 participants fulfilled the inclusion criteria. For 45.7% of these, results were due. Trials funded by the industry had approximately quadruple chances of being published, adjusting for their design, masking, comparator, and participant age group. Moreover, trials testing vitamin supplement safety are more likely to report their findings as compared to vitamin efficacy. Many vitamin supplementation trials registered in the EudraCT failed to report their results and adhere to the EMA regulations. Stricter regulations should be imposed concerning trial results reporting to increase transparency and public trust.","PeriodicalId":72810,"journal":{"name":"Dietetics (Basel, Switzerland)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42949836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to determine discretionary beverage consumption amongst 18 to 30-year-olds residing in New South Wales, Australia. Data were collected in 2017/2018 during the MYMeals study in which 1044 participants recorded their food and beverage consumption over a three-day period, using the purpose-designed Eat and Track (EaT) app. Discretionary beverages included all water-based and milk-based drinks with added sugar, intense sweeteners or fats and excluded alcoholic beverages. Descriptive statistics were used to analyse the proportion of consumers for different types of beverages, and contribution to overall energy and nutrient intakes. ANCOVA analyses compared the energy and nutrient intakes of consumers and non-consumers, adjusted for gender and age group. Sixty-two percent of participants with complete data (n = 1001) were classified as consumers of discretionary beverages. The most consumed beverages were soft drinks (39.0%) and flavoured tea/coffee (23.1%). The greatest proportion of nutrients contributed by discretionary beverages was total sugars (27.2% of total per consumers). In comparison to non-consumers, consumers of discretionary beverages had higher mean daily intakes of energy (kJ) (8736 versus 7294), and higher percentage energy (%E) from total sugars (16.5 versus 13.3) (p < 0.001) and saturated fat (12.5 versus 12.0) (p < 0.05) but lower protein (18.5 versus 20.5) (p < 0.001).

In this study, we assess the relation between adherence to different dietary patterns and biochemical and metabolic parameters as well as the 10-year risk of major cardiovascular diseases (CVDs) in a community of blood donors in Northern Italy. We assess their adherence to four dietary patterns, namely, the Dietary Approach to Stop Hypertension (DASH) diet, the Mediterranean diet through the Greek and Italian Mediterranean Indices (GMI and IMI) and the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet, using a validated semi-quantitative food frequency questionnaire (FFQ). We then assess their association with blood parameters and the 10-year risk of major CVD using a spline regression model. We found an inverse association between the DASH and MIND diets and total and LDL cholesterol, and triglyceride and HDL cholesterol values for the Mediterranean diets (IMI and GMI). Additionally, according to our sex-stratified analyses, men who have greater adherence to dietary patterns have a decreased risk of major CVD for all patterns. The results suggest that greater adherence to dietary patterns positively influences blood biochemical and metabolic parameters, thus reducing the risk of developing cardiovascular disease and delaying the use of drug treatments.","PeriodicalId":72810,"journal":{"name":"Dietetics (Basel, Switzerland)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41382518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
