EPIC-Oxford. The Oxford component of EPIC is a prospective cohort of 57 500 men and women recruited throughout the United Kingdom in 1993–2000. Recruitment was targeted to include as many vegetarians as possible, and approximately 50% of the participants do not eat meat. The main objective of the study is to examine how diet influences the risk of cancer, particularly for the most common types of cancer in Britain, as well as other chronic diseases.
