Major known risk factors for breast and endometrial cancers are obesity, low physical activity, and unhealthy and poor diet, contributing to about 30%-35% of cancer incidence. Recent evidence supports that adherence to a healthy dietary pattern such as the Mediterranean diet (MD) is associated with reduced risk of certain types of cancer, including breast and endometrial cancers. The data for the current review were identified through a systematic search on PubMed, Scopus, and Cochrane databases using the following search terms/keywords: “Mediterranean diet,” “Mediterranean dietary pattern,” “breast,” “mammary,” “endometrial,” “cancer,” “carcinoma,” and “neoplasm.” The reference lists of the included papers were also searched manually. Through the review process, eight case-control studies, four cohort studies, and one clinical trial were identified. The included studies were conducted among postmenopausal and premenopausal women in the United States and some European countries. The review suggests a protective role for the MD against breast cancer risk in both populations. According to the fact that there was insufficient research on the association of the MD pattern and endometrial cancer risk, its protective effect cannot be interpreted with certainty. Further studies in this area, especially interventional studies, are needed to determine causality.","PeriodicalId":277962,"journal":{"name":"Journal of Nutritional Sciences and Dietetics","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130940046","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}

However, serum vitamin E to cholesterol ratio was not significantly different between smokers and nonsmokers. Moreover, the highest circulating concentrations of vitamin E was observed in smokers who smoked ≤9 cigarettes per day (p < 0.03), while and the lowest vitamin E was seen in men smoking ≥20 cigarettes per day. \u0000Conclusion: The results of this study identified that cigarette smoking is associated with lower levels of serum vitamin E and vitamin A, although it was not associated with vitamin E to cholesterol ratio.","PeriodicalId":277962,"journal":{"name":"Journal of Nutritional Sciences and Dietetics","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122430081","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 results of studies cannot be compared and concluded, because these studies have different operational definitions, such as considering food quality rather than the amount of food intake and also limiting some causes of food insecurity in the analysis and the presentation of results in others. Therefore, we investigated the effects of food insecurity on food diversity and the nutritional and anthropometric status of the elderly in Tehran. \u0000Methods: This cross-sectional study was performed on 300 elderly residents in Tehran, with a mean age of 67.5 ± 5.74. Food insecurity was evaluated using the Household Food Insecurity Access Scale (HFIAS). The nutritional status and health of the elderlies were assessed using the Mini Nutritional Assessment (MNA). Waist circumference, weight, and height were measured and BMI was calculated. All statistical calculations were performed with the SPSS. \u0000Results: The prevalence of malnourishment was significantly (p < 0.001) higher in the severely food-insecure group (62.5%). A significant inverse relationship was observed between the HFIAS scores and weight (β = -4.38, p < 0.001), body mass index (β = -1.46, p < 0.001), waist circumference (β = -3.37, p = 0.002), and dietary diversity score (DDS) (β = -0.738, p < 0.001). Moreover, we found a significant relationship between HFIAS and MNA scores (β = 0.486, p < 0.001). Participants in the food-insecure group had a greater risk of developing malnourishment (OR, 16.45; 95% CI, 8.55-31.66) and having poor dietary diversity (OR, 7.42; 95% CI, 2.87-19.16) compared with the food-secure group. \u0000Conclusion: After adjusting for possible confounding factors, we found that food insecurity was associated with MNA score. We also found an inverse association between food insecurity and socioeconomic status, anthropometric measurements, and dietary diversity.","PeriodicalId":277962,"journal":{"name":"Journal of Nutritional Sciences and Dietetics","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122013345","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}

Bio-social conditions and acute or chronic diseases are the most important factors affecting nutrition. It has been suggested that awareness of the prevalence and severity of malnutrition in hospitalized patients can be used by managers to understand the causes, health care system requirements, and health plans. \u0000Methods: Medical records of 483 patients from 11 different wards of Shariati general hospital were assessed to evaluate the quality of nutritional assessment and the rate of referral to nutrition experts by physicians. This study consisted of two phases: evaluation of initial nutritional assessment and assessing the accuracy of malnutrition screening forms completion. \u0000Results: Our study showed no initial nutritional assessment for 34% of the patients. Assessment of the accuracy of malnutrition screening showed that there was a considerable error in the reporting of BMI (66%), weight loss (51%), appetite loss (50%), and severity of the patient’s situation (39%). Also, the rate of referral to a nutritionist was 0% and 1% in the first and second phases of the study, respectively. \u0000Conclusion: The present study showed that the quality of nutritional screening and subsequent referral to nutrition experts for professional nutritional assessment is negligible in Shariati hospital, Tehran, Iran.","PeriodicalId":277962,"journal":{"name":"Journal of Nutritional Sciences and Dietetics","volume":"549 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131985604","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}
