The most prevalent non-communicable diseases of our time, such as obesity, type 2 diabetes, cardiovascular diseases and certain types of cancer, are on the rise globally due to inflammatory disorders, impaired immune functions and alterations in gut microbiota. Nutrition plays a crucial role in modulating the interaction between immune system and microbiota, with Westernized diet negatively impacting both, while Mediterranean diet positively influences them. Precision nutrition is emerging as a new approach for the treatment and prevention of these diseases.
The most prevalent diseases of our time, non-communicable diseases (NCDs) (including obesity, type 2 diabetes, cardiovascular diseases and some types of cancer) are rising worldwide. All of them share the condition of an inflammatory disorder, with impaired immune functions frequently caused or accompanied by alterations in gut microbiota. These multifactorial maladies also have in common malnutrition related to physiopathology. In this context, diet is the greatest modulator of immune system-microbiota crosstalk, and much interest, and new challenges, are arising in the area of precision nutrition as a way towards treatment and prevention. It is a fact that the westernized diet (WD) is partly responsible for the increased prevalence of NCDs, negatively affecting both gut microbiota and the immune system. Conversely, other nutritional approaches, such as Mediterranean diet (MD), positively influence immune system and gut microbiota, and is proposed not only as a potential tool in the clinical management of different disease conditions, but also for prevention and health promotion globally. Thus, the purpose of this review is to determine the regulatory role of nutritional components of WD and MD in the gut microbiota and immune system interplay, in order to understand, and create awareness of, the influence of diet over both key components.
