Understandably in these unprecedented times, interest in nutrition and diet in relation to immunity has increased, but misconceptions and confusion are common.

The immune system is a complex network of cells and chemical compounds that help defend the body against infections. A number of different nutrients, including protein, omega-3 fats and many vitamins and minerals, found in a wide range of foods, are involved in supporting our immune systems to work normally. So having a healthy, varied diet helps us to get the nutrients that are important for your immune system, as well as all the other systems of the body, promoting health and wellbeing.

Wherever possible, vitamin and mineral intakes should come from a nutritionally balanced and diverse diet. It is also essential that taking supplements or certain foods that may be promoted as ‘immune boosting’ are not seen as effective alternatives to recognised measures that help to prevent infections spreading like hand washing and social distancing, or to vaccination.
