There is some evidence that what you eat and drink may affect your risk for developing lung cancer. This chart, compliments of World Cancer Research Fund and the American Institute for Cancer Research’s 2007 report Food, Nutrition, Physical Activity, and the Prevention of Cancer: a Global Perspective, outlines the evidence:

Convincing – there is enough evidence to support a convincing causal relationship, one that is “robust enough to be highly unlikely” to change in the future as new evidence is found.
Probable – there is enough evidence to support a probable causal relationship that it would reduce the incidence of cancer.
Limited-suggestive – evidence is too limited to allow a probable or convincing causal relationship but there is evidence of a direct effect.
Limited-no conclusion – evidence is so limited that a firm conclusion cannot be made. This does not necessarily indicate there is no relationship, there is just not enough evidence to say one way or the other.
