Stevia is a non-nutritive sweetener, providing sweet taste with no calories. This randomised, controlled, open-label 2-parallel arm trial examined the effects of daily stevia consumption on glycaemia in healthy adults. Secondary endpoints included body weight (BW) and energy intake (EI). Healthy participants (n = 28; aged 25 ± 5y, body mass index 21.2 ± 1.7 kg/m²) were randomised into either the stevia group (n = 14)—required to consume a stevia extract daily—or to the control group (n = 14). At weeks 0 and 12, the glucose and insulin responses to an oral glucose tolerance test were measured; BW and EI were assessed at weeks 0, 6, and 12. There was no significant difference in the glucose or insulin responses. There was a significant main effect of group on BW change (F(1,26) = 5.56, p = 0.026), as the stevia group maintained their weight as opposed to the control group (mean weight change at week 12: −0.22 kg, 95%CI [−0.96, 0.51] stevia group, +0.89 kg, 95%CI [0.16, 1.63] control group). The energy intake was significantly decreased between week 0 and 12 in the stevia group (p = 0.003), however no change was found in the control group (p = 0.973). Although not placebo-controlled, these results suggest that daily stevia consumption does not affect glycaemia in healthy individuals, but could aid in weight maintenance and the moderation of EI.

Background/Aims: Epidemiological associations have implicated factors associated with Westernization, including the Western diet, in the development of inflammatory bowel disease (IBD). The role of diet in IBD etiopathogenesis, disease control and symptom management remains incompletely understood. Few studies have collected data on the dietary habits of immigrant populations living with IBD. Our aim was to describe the dietary practices and beliefs of British South Asians with IBD.Methods: A 30-item questionnaire was developed and consecutively administered to 255 British South Asians with IBD attending gastroenterology clinics in the United Kingdom.Results: Fifty-one percent of participants believed diet was the initiating factor for their IBD and 63% felt diet had previously triggered disease relapse. Eighty-nine percent avoided certain dietary items in the belief that this would prevent relapse. The most commonly avoided foods and drinks were spicy and fatty foods, carbonated drinks, milk products, alcohol, coffee, and red meat. A third of patients had tried a whole food exclusion diet, most commonly lactose- or gluten-free, and this was most frequently reported amongst those with clinically active IBD (P= 0.02). Almost 60% of participants avoided eating the same menu as their family, or eating out, at least sometimes, to prevent IBD relapse.Conclusions: British South Asians with IBD demonstrate significant dietary beliefs and food avoidance behaviors with increased frequency compared to those reported in Caucasian IBD populations. Studies in immigrant populations may offer valuable insights into the interaction between diet, Westernization and cultural drift in IBD pathogenesis and symptomatology.

Background The role of diet in inflammatory bowel disease (IBD) remains incompletely understood. Knowledge around the actual dietary advice healthcare professionals provide to individuals with IBD is scarce. Our objective was to describe the dietary beliefs of healthcare professionals and dietary recommendations made to people with IBD. Methodology An online survey regarding IBD-related dietary beliefs and advice provided to patients was distributed to gastroenterologists, dietitians and IBD nurses in the UK. Results Two-hundred and twenty-three eligible healthcare professionals participated: 107 (48%) believed that diet was involved in IBD development. The most frequently implicated dietary components were processed foods (78%), additives/preservatives (71%), sweet/sugary foods (36%), red meat (36%) and fatty foods (31%). Views were broadly consistent across professions, however, gastroenterologists were significantly more likely to believe red meat and additives/preservatives initiated IBD. One hundred and thirteen participants (53%) believed that diet could trigger disease relapse and 128 (61%) recommended limiting specific foodstuffs to reduce this risk, most commonly high fibre foods. Forty-six (23%) considered recommending a low Fermentable Oligo-, Di- and Monosaccharides and Polyols diet to reduce relapse risk. IBD nurses and healthcare professionals with <5 years experience were most likely to recommend this. Dietitians felt most comfortable providing dietary advice for functional gastrointestinal symptoms in quiescent IBD. Conclusion Dietary advice in IBD is inconsistent reflecting uncertainty among healthcare professionals. While some consensus exists regarding dietary components implicated in IBD development and relapse, dietary recommendations varied. Future research is required to disentangle these complex relationships, alongside better training and education.

Background: The risk of bloodstream infections may be increased in hospitalized patients receiving ready‐made parenteral nutrition (PN) multichamber bags (MCBs) compared with customized PN; however, as highlighted in recent international guidelines, there are no comparable data relating to home PN (HPN).Methods: Data from a prospectively maintained database were analyzed to compare incidence rates of catheter‐related bloodstream infections (CRBSIs) between patients receiving customized HPN compared with MCB HPN at a national UK referral center between May 2018 and August 2020.Results: Sixty patients with chronic intestinal failure were commenced on MCBs and 45 received customized HPN for a total of 5914 and 7641 catheter days, respectively. No difference in CRBSI incidence was found (0.51/1000 catheter days for MCBs, 0.39/1000 catheter days for customized HPN; incidence rate ratio, 1.29; 95% CI, 0.26–6.37). Eighteen patients were switched from customized HPN to MCB HPN. The study period covered 7401 catheter days receiving customized HPN and 4834 days on MCBs. No significant change was noted in the CRBSI rates following this switch (0.27/1000 catheter days receiving customized HPN vs 0.21/1000 catheter days on MCBs; incidence rate ratio, 1.31; 95% CI, 0.12–14.3).Conclusion: The use of MCBs for HPN patients is not associated with an increased risk of CRBSI. This study will inform international guidelines and provide reassurance for the continued, safe use of MCB HPN.

Background and Objectives: The role of diet in inflammatory bowel disease (IBD) remains incompletely understood. Studies have previously examined dietary practices in IBD, but none have specifically focused on older-onset disease. IBD may put vulnerable groups at risk of nutritional deficiency and associated complications, potentially heightened by comorbidities, frailty and polypharmacy. Our objective was to describe dietary practices and beliefs in older-onset IBD. Methods: A questionnaire exploring dietary practices and beliefs was prospectively administered to 137 people with older-onset IBD attending gastroenterology clinics. Results: Thirty-two percent believed diet was the initiating factor for their IBD. This was significantly more likely in people with Crohn’s disease than ulcerative colitis (P = 0.05) and in those who felt limited in their dietary choices due to cost (P = 0.008). Forty-three percent believed diet could trigger IBD relapse and 68% avoided dietary components to avoid relapse. Most frequently avoided were spicy and fatty foods, carbonated drinks, red meat, alcohol and raw fruit and vegetables. Twenty-two percent of participants had tried a whole food exclusion diet, most frequently gluten- or lactose-free. Almost a third avoided eating out (29%) or eating the same meal as their family (32%) to prevent relapse. Respondents rarely relied upon healthcare professionals or patient support organisations for their dietary information. Conclusion: Individuals with older-onset IBD report dietary practices with a high degree of consistency. Dietary avoidance may impact upon both nutritional and psychosocial wellbeing in this more vulnerable group and, as such, early dietetic assessment could help improve outcomes.
