Bringing Foodstuffs into UK (canned beans)

My grandson has significant allergies. He is being treated by introduction of specific foods and needs to eat them weekly to keep the treatment going. He has a limited selection of foods he can eat. He is trying a particular bean (pink beans), which are almost impossible to find in UK. Common in US and canned by main stream food supplier. Can my daughter bring a couple of cans with her in her luggage from the US. Thanks
