Colorectal cancer is the third most common cancer, with a lifetime risk of approximately 4 to 5%. Genetic background and environmental factors play major roles in the pathogenesis of colorectal cancer. Theoretically, a multistep process of colorectal carcinogenesis provides enough time for anti-tumor pharmacotherapy of colorectal cancer. Chronic colonic inflammation, oxidative stress, and gut microbiota imbalance have been found to increase the risk for colorectal cancer development by creating genotoxic stress within the intestinal environment to generate genetic mutations and epigenetic modifications. Currently, numerous natural polyphenols have shown anti-tumor properties against colorectal cancer in preclinical research, especially in colorectal cancer cell lines. In this review, the current literature regarding the etiology and epidemiology of colorectal cancer is briefly outlined. We highlight the findings of natural polyphenols in colorectal cancer from in vitro and in vivo studies. The scarcity of human trials data undermines the clinical use of natural polyphenols as anti-colorectal cancer agents, which should be undertaken in the future.</p>","PeriodicalId":10844,"journal":{"name":"Current Nutrition Reports","volume":null,"pages":null},"PeriodicalIF":4.9,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138470077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A scoping review was conducted based on a methodological framework developed by Arksey and O'Malley (Int J Soc Res Methodol 8:19-32, 2005).

Barriers and facilitators for donating and accepting breast milk were categorized under six themes: individual, family, community, workplace, health system, and policy-related. The common individual barriers were time requirements for BMD, personal dislike of the process, lack of knowledge, insufficient milk, negative opinions, and lack of information. Family stigma, negative rumors, less educated family members, and illness of a family member were identified as family-related barriers. Community-related barriers include cultural or religious unacceptable practices, societal taboos, and distance to milk banks. The major barriers identified in relation to the health system were lack of practical and psychological support, lack of information, storing and transportation issues, lack of knowledge among HCWs, and logistical challenges of creating a milk lab. The common work-related barriers were the lack of adequate time, philosophical objections, and incomprehension at returning to work. Policy-related barriers identified include the need for hygiene requirements, donation costs, and lack of standardized guidelines. Making the donation process faster, providing pick-up services for donors, and community education and male partner engagement regarding breast milk donation could help to boost the acceptability of breast milk donation.</p>","PeriodicalId":10844,"journal":{"name":"Current Nutrition Reports","volume":null,"pages":null},"PeriodicalIF":4.6,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10766659/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138298609","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
