Sweets and Inflammatory Bowel Disease: Patients Favor Artificial Sweeteners and Diet Foods/Drinks Over Table Sugar and Consume Less Fruits/Vegetables

Background While artificial sweeteners are deemed safe, preclinical studies indicate that artificial sweeteners contribute to gastrointestinal inflammation. Little is known about patients' perceptions and consumption of artificial sweeteners in inflammatory bowel disease (IBD). We surveyed the consumption frequency and beliefs of IBD patients and control participants regarding artificial sweeteners. Methods We surveyed 130 individuals (IBD patients, n = 93; control/non-IBD participants, n = 37) among our tertiary hospital population to determine consumption frequency and beliefs regarding artificial sweeteners (Splenda/sucralose, Stevia/stevia, NutraSweet/Equal/aspartame). A 14-question questionnaire surveyed the frequency of 9 dietary habits, preferences, and beliefs on health benefits of commercial artificial sweeteners, using the following as positive and negative control questions: table sugar, water, fruits/vegetables, and coconut-oil, among others. Results Despite the similarity in yes/no consumption data, artificial sweeteners (Q4 t test P = .023) and diet (low calorie) foods/drinks (Q4 t test P = .023) were consumed more frequently by patients with IBD than by control participants, while no difference in preference for water instead of juices/sodas was observed between IBD patients and control participants. Conversely, patients with IBD consumed table sugar less frequently than control participants (Q1 t test-P = .09), in agreement with their reporting of sugary foods as cause of symptoms (P < .01). A positive correlation was observed between artificial sweeteners and fresh fruits/vegetables among the first 31 IBD patients (Spearman P = .017) and confirmed with 62 new IBD patients (r = 0.232; 95% CI, 0.02-0.43; P = .031), indicating that artificial sweeteners are deemed a healthy habit in IBD. Excluding fresh fruits/vegetables, multivariate analyses to develop surrogate principal component analysis indexes of healthy habits confirmed that artificial sweeteners consumption follows healthy preferences among our IBD patients (adjusted P < .0001). Conclusions Consumption of artificial sweeteners correlated with healthy habits, suggesting that our IBD population deemed artificial sweeteners as healthy and/or had preferences for naturally or artificially sweetened flavors and products. Lay Summary Artificial sweeteners and artificially sweetened (diet, low calorie) foods/drinks are consumed more often by inflammatory bowel disease patients compared with control participants, and inflammatory bowel disease patients deem artificial sweeteners consumption as a healthy habit, when differentiating between table sugar and artificial sweeteners.
