Optimising your ability to Fight Infection

With the current Coronavirus pandemic, it feels like a good time to discuss what we can do to make our bodies better at fighting infection (our immune response). In the future we will go into more detail about just how this works, but this post (and podcast) concentrates on the things we can all do to improve our chances of reducing the number of viral type illnesses we get (whether COVID-19 or the common cold).

As our parent site, St Emlyn’s Blog, Professor Simon Carley interviewed two experts: Dr John Rogers (consultant in Sport and Exercise Medicine) and Dr Nathan Lewis (a leading performance nutrition scientist) and you can hear the interview here.

The main messages are beautifully summed up in this cool infographic (which you can print out). Although much of the research was done in elite atheletes it seems sensible to give it a try, and there’s no evidence that it can do any harm. Be sure to check with your parents before you start taking any supplements though.
