In 1192 biopsy proven cases of carcinoma of the oral cavity and oropharynx information was collected on the use of various chewing, smoking, and eating habits. The quantity used and the duration of use were also recorded. Information was also collected on the frequency of use of cereals, dairy products, meat, fish, fruits and vegetables. The information from carcinoma cases was compared with that from apparently healthy individuals.
