‚ÄčA decline in the risk of oral, pharyngeal, and laryngeal cancer is associated with increase in the consumption of fruits and vegetables.

‚ÄčThis study explored the relationship between the frequency of consumption of fruits and vegetables and the incidence of cancers affecting the head and neck, such as oral, pharyngeal, and laryngeal cancer. Researchers assessed the dietary and hospital records of more than 450,000 US men and women recruited from the NIH-AARP Diet and Health cohort. 

Researchers found out that high consumers of fruits and vegetables had better chances of preventing oral, pharyngeal, and laryngeal cancer that their colleagues who consumed little or none of these plant foods. "Results from this large prospective observational study are consistent with previous case-control studies and support the hypothesis that total fruit and vegetable intake is associated with reduced risk of head and neck cancer," the authors concluded.
