Plain language summary
Irritable bowel syndrome (IBS) is a complex condition characterized by recurrent abdominal pain associated with abnormal bowel habits. Diet is considered a main cause of symptoms in IBS, and fermentable oligo-, di-, monosaccharides, and polyols (FODMAPs) are of major concern. The aim of this study was to unravel determinants of differential IBS responses to FODMAP and gluten provocation interventions from molecular data. This study was a randomised, double-blind, placebo-controlled three-way crossover study. Participants were randomised in blocks of 12 into the sequences CBA, ACB, and BAC (A=FODMAPs, B=Gluten, and C=Placebo). Results showed that despite a comprehensive set of methods applied to explore IBS responses, including both regression and classification, predictors of differential response could not be established. Authors concluded by encouraging the application of molecular subtyping methodologies in future studies due to the differential responses to treatment.
Abstract
INTRODUCTION There is large variation in response to diet in irritable bowel syndrome (IBS) and determinants for differential response are poorly understood. OBJECTIVES Our aim was to investigate differential clinical and molecular responses to provocation with fermentable oligo-, di-, monosaccharides, and polyols (FODMAPs) and gluten in individuals with IBS. METHODS Data were used from a crossover study with week-long interventions with either FODMAPs, gluten or placebo. The study also included a rapid provocation test. Molecular data consisted of fecal microbiota, short chain fatty acids, and untargeted plasma metabolomics. IBS symptoms were evaluated with the IBS severity scoring system. IBS symptoms were modelled against molecular and baseline questionnaire data, using Random Forest (RF; regression and clustering), Parallel Factor Analysis (PARAFAC), and univariate methods. RESULTS Regression and classification RF models were in general of low predictive power (Q2 ≤ 0.22, classification rate < 0.73). Out of 864 clustering models, only 2 had significant associations to clusters (0.69 < CR < 0.73, p < 0.05), but with no associations to baseline clinical measures. Similarly, PARAFAC revealed no clear association between metabolome data and IBS symptoms. CONCLUSION Differential IBS responses to FODMAPs or gluten exposures could not be explained from clinical and molecular data despite extensive exploration with different data analytical approaches. The trial is registered at www. CLINICALTRIALS gov as NCT03653689 31/08/2018.

Plain language summary
Ulcerative colitis (UC) is a form of inflammatory bowel disease, that may be caused by genetic variations in the gut microbiome, immune dysregulation, and environmental influences. Symptoms include diarrhoea, constipation, cramping, joint pain, bleeding, and anaemia. Inflammation is a direct driver of UC, which if controlled may be of benefit to the individual. Spirulina, which is a species of seaweed, has been shown to have anti-inflammatory properties and this randomised control trial aimed to determine the effects of its supplementation on 80 individuals with UC and associated health outcomes. The results showed that 8-weeks of Spirulina supplementation significantly increased antioxidant capacity compared to placebo. However, an assessment of quality of life and level of disease showed no improvements with Spirulina supplementation. It was concluded that Spirulina supplementation for 8-weeks improved antioxidant status, but it did not affect severity of disease or quality of life. This study could be used by healthcare professionals to understand that Spirulina supplementation for 8-weeks can improve inflammation. However, it would be interesting to see longer studies to determine if this would affect disease status if supplemented for a longer period of time.
Abstract
AIM: We conducted a randomized placebo-controlled trial to assess the efficacy of Spirulina (SP) supplementation on disease activity, health-related quality of life, antioxidant status, and serum pentraxin 3 (PTX-3) levels in patients with ulcerative colitis (UC). METHODS Eighty patients with UC were randomly assigned to consume either 1 g/day (two 500 mg capsules/day) of SP (n = 40) or control (n = 40) for 8 weeks. Dietary intakes, physical activity, disease activity, health-related quality of life, antioxidant status, erythrocyte sedimentation rate (ESR), and serum PTX-3 levels were assessed and compared between groups at baseline and post-intervention. RESULTS Seventy-three patients (91.3%) completed the trial. We observed increases in serum total antioxidant capacity levels in the SP supplementation group compared to the control group after 8 weeks of intervention (p ≤ 0.001). A within-group comparison indicated a trend towards a higher health-related quality of life score after 8 weeks of taking two different supplements, SP (p < 0.001) and PL (p = 0.012), respectively. However, there were no significant changes in participant's disease activity score in response to SP administration (p > 0.05). Similarly, changes in ESR and PTX-3 levels were comparable between groups post-intervention (p > 0.05). CONCLUSIONS SP improved antioxidant capacity status and health-related quality of life in patients with UC. Our findings suggest that SP supplementation may be effective as an adjuvant treatment for managing patients with UC. Larger trials with longer interventions periods are required to confirm our findings.

Abstract
Obesity and its impact on the prevalence of diabetes and subsequent cardiovascular disease is one of the major health burdens in Western societies. Intensive lifestyle intervention programmes have been shown to be successful, even in individuals with pre-diabetes. Nutrition and lifestyle interventions targeting blood sugar regulation, fibre intake for microbiome health and healthy habits formed in childhood all have a role to play.

Abstract
Gut microbial irregularities can lead to increased gut inflammation and gut membrane damage in people with long covid. Symptoms such as cough and breathlessness are apparent in Covid 19 patients with harmful gut bacterial overgrowth. In Covid patients, antibiotic and dexamethasone treatment also aggravates gut microbial imbalances. Lactobacillus supplementation has been shown to lessen upper respiratory tract infection, increase gut bacterial diversity, improve gut wall integrity, reduce gastrointestinal symptoms and gut inflammation, decrease oxidative stress and improve immunity. This study analysed the efficacy of probiotics and prebiotics combined supplements in reducing the severity and longevity of symptomatic Covid infection. 126 participants with Covid symptoms consumed two capsules a day for a month of a supplement containing 5 species of Lactobacillus and chicory inulin. 32% of participants were in the early phase of infection, and 68% were in the late phase. Both early and late phase participants showed significant improvements in cough, fatigue, and subjective wellbeing after 30 days of intervention. The gut symptoms of 82% of the participants improved after a month of intervention. Inulin and Lactobacillus strains need to be studied further robustly to determine whether they provide additional benefits. Healthcare practitioners can use the results of this study to consider symbiotic interventions for those with Covid symptoms.

Abstract
Chris talks about the factors implicated in the development of osteoporosis such as inflammation, both systemic and in the gut (gut-bone axis) via production of inflammatory cytokines which can directly impact bone density. He reviews the evidence for high dose calcium supplements for osteoporosis and whether they are safe, and considers other nutrients involved in calcium metabolism such as vitamins D, K2, B, C, E, and minerals Magnesium, Silica and Collagen. Beyond the diet, bone mineral density has been shown to significantly increase with weight bearing exercise, and both sleep and stress may also impact bone density via the action of melatonin and cortisol.
