From the Bristol City Council Food Charter 2010:
Access to safe, affordable and nutritious food is vital for people to be able to live fulfilled, active and healthy lives, in line with article 25 of the UN Declaration of Human Rights and WHO Ottawa Charter for Health Promotion.
As a local authority, the council has a responsibility for the health, wellbeing and sustainability of the city, on behalf of and in the interests of the people of Bristol. The council is tasked with “ensuring the availability of, and access to, affordable, safe and nutritious food sufficient for an active lifestyle, for all, at all times” (Cabinet Office 2008).
