A charity's calling on the government to fund more research into why people from ethnic minority backgrounds appear more likely to develop allergies

The Natasha Allergy Research Foundation says the issue has received little attention.

The charity was set up following the death of Natasha Ednan-Laperouse from Fulham, who died after eating a baguette which contained sesame seeds.

The Pret-a-Manger baguette didn’t list the allergens it contained.

A 2012 study in America found that around one in five black two-year-olds tested positive for an allergen compared to one in 10 white children.
