A growing body of research has investigated the association between inositol and diabetes. The purpose of this review is to report through a systematic way the current scientific evidence relating potential benefits of inositol isomers on diabetes/gestational diabetes. The screening of the studies published last decade was performed in 4 databases (Pubmed-Web of Science-The Cochrane Library-Lilacs). Among the 1640 studies identified in the search, only 26 studies had sufficient data to be included in the systematic review. The available literature suggests that inositol seems to be provide improvements in fasting blood glucose and other biochemical results, which are among the most important parameters in diabetic individuals. Although there are some studies demonstrating that inositol may be effective in prevention and treatment of diabetes/ gestational diabetes, conduction of studies with larger sample and longer follow-up duration is required for it to be represented as an effective strategy in management of diabetes.

Chronic inflammation is associated with increasing the risk of colorectal cancer (CRC), and both inflammation and CRC risk are modulated by environmental factors such as diet. The Dietary Inflammatory Index (DII ® ) provides a tool to assess the inflammatory potential of diet and DII score has been linked with several health outcomes (1) . For example, individuals with a high DII score (more inflammatory diet) have been shown to have a 40% increased risk of CRC compared with those with the lowest DII scores (2) .The WNT signalling pathway is involved in the maintenance of homeostasis within the large bowel through the regulation of physiological processes, such as cell proliferation, but is also implicated in colorectal carcinogenesis. Furthermore, interactions between WNT signalling and inflammatory pathways exist (3) .The aim of this study was to investigate relationships between the inflammatory effects of diet, assessed using the DII, and markers of inflammation and of the WNT signalling pathway in the healthy colorectal mucosa.We used samples and dietary data from 75 healthy participants recruited to the DISC Study (3) . Energy-adjusted (E-DII) scores were calculated using food frequency questionnaire data and included 30 food parameters. Systemic inflammation was assessed by quantifying high-sensitivity C-reactive protein (hsCRP) and local inflammation from faecal calprotectin. Expression and methylation of WNT pathway genes were quantified in rectal mucosal biopsies by qPCR and by pyrosequencing, respectively. Correlation and regression analyses between E-DII score and the measured outcomes were performed. Participants were divided into pro-and antiinflammatory groups according to E-DII score by dichotimising at the median (0.700) for categorical analyses using the ANOVA General Linear Model and adjusting for age, gender, BMI, smoking status and endoscopy procedure as covariates. Corresponding non-parametric tests were applied where required.Mean E-DII score within DISC Study participants was 0.736 (range −4.480-5.030). hsCRP concentrations were significantly greater in the pro-inflammatory E-DII group (median = 3.0) compared with the anti-inflammatory group (median = 1.6) (p = 0.03). Positive relationships between E-DII and expression of FOSL1 (p = 0.006) and WNT11 (p = 0.008) were observed. Rectal WNT11 expression was significantly higher in the pro-inflammatory group (Least Squares Mean (LSM) = 0.344) compared with the antiinflammatory group (LSM = 0.243) (p = 0.003).The findings from this study provide evidence for relationships between pro-inflammatory diets (greater DII score) and markers of inflammation and WNT signalling in the healthy colorectal mucosa. Aberrant expression of FOSL1 and WNT11, which increased with greater E-DII scores, has been reported in CRC and associated with effects on functional outcomes such as cell proliferation and migration which are dysregulated in CRC. These findings suggest that WNT signalling may be a mechanism through which diet, particularly inflammatory components ...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
