An “explosion” in a food allergy poses a particular risk to vegans and vegetarians, one of Britain’s leading experts has warned.

Cases of pollen food syndrome (PFS) have risen markedly in recent years as a result of global heating, worsening pollution and changes in pollen patterns, Dr Isabel Skypala said.

Attacks of PFS are usually triggered by eating raw nuts, fruit and vegetables. However, they can also be prompted by foods popular among people who avoid animal products, such as soya milk, avocados, jackfruit, edamame beans and smoothies.

The estimated 13 million Britons who are allergic to pollen, especially birch tree pollen, and suffer from hay fever are most at risk. PFS is caused by unstable pollen antibodies found in proteins in some raw – but not cooked – fruits and vegetables, nuts and soya.
