Cause-and-effect Relationship between Nutrition, Immune Function and Infectious Diseases in the Context of Diet-related Metabolic Disorders

Poor diets and nutrition are major drivers of non-communicable diseases (NCDs). Globally, there are over 2 billion adults with obesity and related NCDs such as type 2 diabetes. The COVID-19 pandemic clearly showed the critical interplay between diet-related metabolic diseases and infectious diseases: metabolic diseases such as obesity and type 2 diabetes increased the severity of COVID-19 infection. In addition to this, the current pandemic highlighted the impact of health inequalities. This emphasized the importance of needing to better understand the role of nutrition in immune function, resilience, and dysfunction, and its interplay between diet-related- metabolic and infectious diseases.

The aim of this research topic is to provide a comprehensive view of the consequence of the interactions between nutrition and immunity on the individual susceptibility to infectious diseases within the context of diet-related metabolic diseases. Review highlighting the future directions of the field and methodological articles on innovative food solutions that may restore immune function are both welcome.

We welcome contributions on understanding of how nutrition, foods, and dietary patterns modulate immune surveillance at any time of the life from people with diet-related metabolic diseases. The submitted manuscripts will undergo peer review and may include original data.
