Reduction in Pain and Pain Intensity with Nonpharmacological Treatment in Severely Obese Patients: A Randomized Clinical Trial

Healthy Diet Consumption Among Chronic Pain Populations: A Concept Analysis

PURPOSE

Given emerging evidence that healthy dietary interventions are effective long-term strategies for managing chronic pain, this review aimed to define, elucidate, and describe the concept of a healthy diet in the context of chronic pain populations.

DESIGN

We used Walker and Avant's concept analysis method.

METHOD

PubMed, Embase, CINAHL Plus with full-text, and PsycINFO databases were searched to identify relevant peer-reviewed primary articles on diet and chronic pain, published from June 2013 to June 2024. Key search terms included "diet" AND "chronic pain or pain."

RESULTS

Twenty-eight primary articles met our eligibility criteria following full-text reviews. In chronic pain, healthy diet attributes (i.e., nutrient density, anti-inflammation, and anti-oxidation) caused by antecedents (i.e., diet and pain assessments) result in consequences like reduced pain intensity and improved quality of life. Therefore, a healthy diet in chronic pain consists of nutrient-dense foods (fruits, vegetables, healthy fats and low calories) that possess strong anti-inflammatory and antioxidant properties, which are essential for optimizing health, alleviating pain, and enhancing overall quality of life.

CONCLUSION

A healthy diet is essential for pain relief and improving the quality of life in individuals with chronic pain.

IMPLICATIONS

Healthcare providers should incorporate individualized culturally appropriate dietary preferences, food intolerance, and food allergy alternatives in dietary interventions. Also, there is a need for tailored dietary interventions for individuals living with chronic pain. Future studies should explore mechanisms through which diet affects pain outcomes.

Is There More to Olive Oil than Healthy Lipids?

The Mediterranean diet is a healthy dietary pattern whose main characteristic is olive oil consumption. The potential health benefits of olive oil have been extensively investigated and the present review provides the more recent clinical evidence supporting the positive impact of olive oil intake on human health. PubMed (n = 227) and Scopus (n = 308) databases were searched for published clinical studies in English over the past six years (October 2016 to December 2022), following key word searches of "olive oil" and "health". Major findings associated olive oil with antioxidant and anti-inflammatory effects, improvement in endothelial function and lipid profile, prevention of obesity, diabetes, cardiovascular and neurodegenerative diseases, and modulation of the gut microbiota. These benefits are attributed to the nutritional composition of olive oil, which has a high content of monounsaturated fatty acids (MUFA) (oleic acid in particular) and minor compounds such as polyphenols (oleuropein and hydroxytyrosol). Although additional research continues to be required, the more recently generated evidence supports the potential of olive oil to contribute beneficially to health and to the prevention and management of a variety of non-communicable diseases, as a consequence of the synergism between its components' complexity.
