Plain language summary
Migraine is a disabling primary headache disorder with 2 major subtypes: migraine without aura and migraine with aura. Certain foods, such as chocolate, caffeine, milk, cheese and alcoholic beverages, have been identified as common triggers of migraine attacks. The aim of this study was to qualitatively summarize data from randomized controlled trials or observational studies on the role of diet patterns, diet-related triggers, and dietary interventions in adults with migraine. This study is a systematic review of forty-three articles. Of the studies included in the review, 11 outlined the evidence on diet patterns, 20 outlined the evidence on diet-related triggers, and 12 outlined evidence on diet as interventions in people with migraine. Results show that evidence regarding the effect of general diet patterns in people with migraine varied in the studies identified. Furthermore, limited high-quality evidence was found. Authors conclude that certain dietary interventions may help to improve clinical outcomes in some people with migraine, but these findings still need to be supported with robust evidence before being recommended for use in clinical practice.
Abstract
BACKGROUND Migraine is a disabling primary headache disorder often associated with triggers. Diet-related triggers are a common cause of migraine and certain diets have been reported to decrease the frequency of migraine attacks if dietary triggers or patterns are adjusted. OBJECTIVE The systematic literature review was conducted to qualitatively summarize evidence from the published literature regarding the role of diet patterns, diet-related triggers, and diet interventions in people with migraine. METHODS A literature search was carried out on diet patterns, diet-related triggers, and diet interventions used to treat and/or prevent migraine attacks, using an a priori protocol. MEDLINE and EMBASE databases were searched to identify studies assessing the effect of diet, food, and nutrition in people with migraine aged ≥18 years. Only primary literature sources (randomized controlled trials or observational studies) were included and searches were conducted from January 2000 to March 2019. The NICE checklist was used to assess the quality of the included studies of randomized controlled trials and the Downs and Black checklist was used for the assessment of observational studies. RESULTS A total of 43 studies were included in this review, of which 11 assessed diet patterns, 12 assessed diet interventions, and 20 assessed diet-related triggers. The overall quality of evidence was low, as most of the (68%) studies assessing diet patterns and diet-related triggers were cross-sectional studies or patient surveys. The studies regarding diet interventions assessed a variety of diets, such as ketogenic diet, elimination diets, and low-fat diets. Alcohol and caffeine uses were the most common diet patterns and diet-related triggers associated with increased frequency of migraine attacks. Most of the diet interventions, such as low-fat and elimination diets, were related to a decrease in the frequency of migraine attacks. CONCLUSIONS There is limited high-quality randomized controlled trial data on diet patterns or diet-related triggers. A few small randomized controlled trials have assessed diet interventions in preventing migraine attacks without strong results. Although many patients already reported avoiding personal diet-related triggers in their migraine management, high-quality research is needed to confirm the effect of diet in people with migraine.

Plain language summary
A common symptom of many conditions is pain, with chronic pain being a significant cause of emotional distress and disability. Chronic pain is associated with a pro-inflammatory state. Diet interventions can be a helpful tool for the management of chronic pain and its associated inflammation. The increase of nutrient-dense, antioxidant-rich foods and the reduction of pro-inflammatory foods, as well as correcting nutrient deficiencies, all appear to have a positive effect on pain. Whilst previous research on the impact of diet therapy in chronic pain yielded varied results, the authors of this article sought to analyse the most important literature to gain more clarity and direction for future research. After a detailed introduction on the different types of pain, the article summarises the outcome of a range of dietary interventions for chronic pain management. These include calorie restriction and fasting, polyunsaturated fatty acids, low-fat plant-based diets, high protein diet, elimination diet, antioxidants and vitamins including vitamin D, fruits and fibres, prebiotics and probiotics. In the discussion, a helpful table presents the key results organised by type of pain (chronic musculoskeletal pain, chronic headache, neuropathic pain, chronic abdominal pain) and the clinical interventions that showed positive outcomes. In conclusion, diet interventions could be part of a multidisciplinary approach in the management of chronic pain. This article yields an oversight of the possible interventions to consider when supporting people with different types of chronic pain.
Abstract
Pain is one of the main problems for modern society and medicine, being the most common symptom described by almost all patients. When pain becomes chronic, the life of the patients is dramatically affected, being associated with significant emotional distress and/or functional disability. A complex biopsychosocial evaluation is necessary to better understand chronic pain, where good results can be obtained through interconnected biological, psychological, and social factors. The aim of this study was to find the most relevant articles existent in the PubMed database, one of the most comprehensive databases for medical literature, comprising dietary patterns to alleviate chronic pain. Through a combined search using the keywords "chronic pain" and "diet" limited to the last 10 years we obtained 272 results containing the types of diets used for chronic pain published in the PubMed database. Besides classical and alternative methods of treatment described in literature, it was observed that different diets are also a valid solution, due to many components with antioxidant and anti-inflammatory qualities capable to influence chronic pain and to improve the quality of life. Thirty-eight clinical studies and randomized controlled trials are analyzed, in an attempt to characterize present-day dietary patterns and interventions to alleviate chronic pain.
