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.

Plain language summary
A woman’s menopausal years are believed to bring about weight gain due to various biological mechanisms, such as depletion of oestrogen. Many women undertake weight loss diets, in an attempt to control the weight gain, and although weight loss can reduce the risk factors for metabolic and cardiovascular disease etc, it can also lead to accelerated loss bone density and muscle mass. The objective of this study was to investigate whether by complementing a low-calorie diet with 4 to 5 servings of low-fat dairy foods per day and/or supplementing with calcium and vitamin D supplements would aid weight loss and preserve either/both bone and muscle mass. The study was conducted on 189 early postmenopausal, obese women. It was a randomized, placebo-controlled clinical trial conducted over 6 months. Researchers found that results were better for the participants on the low-fat dairy foods and those supplementing with calcium and vitamin D when compared to the placebo group (who only had placebo pills). They suggest that when embarking on a weight loss program it is beneficial to include 4 to 5 servings of low-fat dairy foods each day and take calcium and vitamin D supplements will have a positive impact on weight loss, bone density and muscle mass in post-menopausal women.
Abstract
Several studies have investigated the possibility of dairy foods and calcium (Ca) mediating weight and body composition, but a consensus has not been reached. We aimed to investigate weight-loss-related outcomes during intervention with low-fat dairy foods or Ca + vitamin D supplements, both as complements to hypocaloric diets. Overweight/obese Caucasian, early-postmenopausal women (n = 135) were recruited for a 6 month energy-restricted weight loss study complemented with either low-fat dairy foods (D; 4-5 servings/day), or Ca + vitamin D supplements (S); both to amount a total of ~1500 mg/day and 600 IU/day of Ca and vitamin D, respectively, or placebo pills (C). Bone mineral density (BMD) and lean and fat tissue were measured by Lunar iDXA. Serum and urinary markers of bone turnover were analyzed. Diet and physical activity were assessed with 3-day records. Participants on average lost ~4%, ~3%, and ~2% of body weight, fat, and lean tissue, respectively. The significantly better outcomes were noticed in participants in the D group regarding body composition (fat loss/lean tissue preservation) and in participants in the S group regarding the BMD outcomes, compared to those in the C group. Therefore, increasing low-fat dairy foods to 4-5 servings/day and/or increasing Ca & vitamin D intake by supplements (in those who are at the borderline dietary intake) may be beneficial for weight loss/maintenance and may lead to more favorable bone and body composition outcomes in postmenopausal women during moderate weight loss.
