Currently, around 40 per cent of children in the UK have been diagnosed with an allergy of some form or another – the most common being food allergies, eczema, asthma, and hay fever. Why is this number so alarmingly high, what can we do to treat them, and what measures can we take to ensure that our children don’t develop allergies in the first place?

In this episode, we’re joined by Willem M. de Vos, a professor of microbiology based at Wageningen University in the Netherlands.

He tells us how the recent rise in births by caesarean section may be contributing to the increase in childhood allergies, how exposure to microbes in early life can have a profound effect on our immune systems, and how cutting-edge microbial treatments such as faecal transplants are showing promise in our fight against this growing health epidemic.
