Implementing
Evidence-Based Nutritional Therapy
Diet is a powerful tool when used as part of a comprehensive medical management plan.
What is Nutritional Therapy
Diet is Essential to the Management of IBD
The role of nutrition in IBD is moving beyond its utilization to treat malnourished patients, although malnutrition remains a common IBD complication. Dietary intake is now recognized for its central role in defining the gut microbiome, which directly influences the underlying immune system and the integrity of the gastrointestinal lining. Metabolomics research is further uncovering complex metabolic pathways in digestion and important byproducts produced, like short-chain fatty acids (SCFAs),1 which are integral in reducing inflammation and achieving balanced immune function. Current research is placing nutrition on the cutting edge of medicine, making nutritional therapy a novel and exciting new adjunctive approach to managing IBD.
The Microbiome and IBD
The microbiome is becoming increasingly recognized for its importance in human health and disease and is one of the hottest topics in medicine right now, with IBD being the most extensively studied among disease states.2 ,3 Microbiome disturbances are commonly found in IBD and are increasingly implicated in the onset and development of IBD.4,5 As diet has the greatest impact on the microbiome, it may offer the most manipulatable lever to modulate it for therapeutic benefit.6,7
Targeting the microbiome with diet upstream in combination with medications targeting the immune system downstream, may offer a two-pronged approach with a potential advantage for improved outcomes.8,9
How Dietary Therapy Can Improve Mental Health
Patients with IBD suffer disproportionally higher rates of depression and anxiety, which are associated with a lower quality of life10,11 and correlated with active disease.12 Furthermore, anxiety, depression, and fatigue, common comorbidities in IBD, are rated by patients to have the highest symptom severity scores in a recent international survey.13
The concept of the gut-brain axis has recently emerged, and it is increasingly accepted that the gut microbiota play an important role in communicating with our brain and regulating mood, including anxiety and depression.14 Disruptions in the gut microbiota, along with important interrelated dynamics of dysregulated stress and immunity, may be converging to influence the development of depression.15
Can diet impact the gut microbiota to influence the gut-brain axis and subsequently our mental health? Increasing data suggest that indeed it does, with diet playing a central role in our brain function, mood, and mental well-being.16 The recognized role of diet in shaping the gut microbiota is changing the available approaches that can be taken to improve a number of health conditions,17 including depression18 and anxiety,19 as pro-inflammatory diets are associated with poor mental health.20 Although more research is needed to fully evaluate the effects of nutrition on mental health, the emerging field of nutritional psychiatry is taking the lead in utilizing dietary interventions to improve mental health. Nutritional therapy may offer an attractive additional therapeutic option for IBD given the potential dual benefit of improving both the underlying condition of IBD and mental health.
Patients Embrace Diet as a Tool
Nutritional therapy is likely one of the clinicians' most powerful tools to alter disease outcomes. Patients recognize the influence of diet on symptoms and are already making efforts to improve their symptoms with perceptive eating.21 They are seeking to utilize diet as a therapeutic tool under the guidance of medical professionals.22 Initiating dietary therapy with their healthcare team allows the greatest benefit to patients by providing a safe and effective approach.
