World Food Day is an event celebrated worldwide every October 16th and serves as a global call to action in the fight against hunger and malnutrition. According to the World Health Organisation, over 2.8 billion people in the world are unable to afford a healthy diet, leading to hunger and malnutrition. Adverse weather conditions, conflicts, economic instability, inequality, and more contribute to the crisis and we all have a part to role to play in improving conditions worldwide, particularly for those most vulnerable.

Journal of Health, Population and Nutrition publishes across a broad range of topics including nutrition and population health in support of the Sustainable Development Goals. Here, we highlight some of our recent articles on food and nutrition to celebrate World Food Day.

The effect of diet on non-communicable diseases

Rheumatoid arthritis is a complex autoimmune disease often accompanied by depression, a common comorbidity. In a recent study by Ma et al., researchers analysed data from 1,148 rheumatoid arthritis patients aged 20 and older and revealed that higher adherence to the Mediterranean diet was linked to reduced depression rates, with specific components like increased vegetable and cereal consumption showing notable benefits. These findings suggest that promoting a Mediterranean dietary pattern could improve mental health outcomes for individuals with rheumatoid arthritis, highlighting the need for further research in larger cohorts. The results also underscore the potential of dietary interventions in improving mental health for those living with rheumatoid arthritis, suggesting avenues for future research in this area.

The impact of public health interventions on nutritional health

Moderate acute malnutrition (MAM) affects many children, yet research on effective interventions is scarce. A recent study in the Kaélé health district of Cameroon revealed that a food voucher program significantly improved nutritional recovery rates, achieving a notable 78.3% recovery within six weeks. Teta et al. suggest that the food voucher program could serve as an effective treatment strategy for MAM, warranting further investigation into its long-term efficacy and scalability.

The importance of fruit and vegetable consumption

The 2002 World Health Report, one of the largest research projects ever undertaken by the WHO, highlighted that inadequate fruit and vegetable (F&V) intake is a significant risk factor for mortality. This study by Küçük et al. investigated factors that influence F&V consumption within households and found a positive relationship was found between the likelihood of F&V choice and attributes such as age, marital status, education, weight, having health insurance, income and time, and forms of physical activity. The group suggest that instead of a general policy for implementing a healthy and balanced nutrition program to improve F&V eating frequency, it may be more effective to adopt programs with distinct characteristics that segregate society into different cohorts.

World Food Day serves as a reminder of the need for collective efforts to eliminate hunger and promote sustainable practices in food production and consumption. Journal of Health, Population and Nutrition continues to publish international and cutting-edge research on nutrition as we contribute to achieving the SDGs.

Happy World Food Day!
