The Food Chain was established by friends of people living with HIV and inspired by similar American organisations. Set up in a time before effective medication was available, physical wasting was common, and good nutrition helped support the immune system and maintain a healthy body mass.
Today, The Food Chain offers a range of nutrition services tailored to provide appropriate support to anyone living with HIV in London. Its services are made possible by the dedication and support of many people who have been volunteers, donors, staff and trustees over the years.
