Research Summary

In July 2006, a research database was constructed to manage the most up-to-date research describing the diet-disease relationship for tomatoes, tomato products and lycopene. This database was updated in 2007, 2009 and now again in 2011 (cut off Oct 2011 for published original research).


Nine (9) publications meeting criteria for this review were available. Data suggest a beneficial effect of tomato/tomato-based foods intake and protection from UV light induced erythema. Of note however is that much of the work supporting this conclusion is from a single laboratory. Additional research from other laboratories is warranted. Research indicates that the protective effect of tomato intake may depend on increased carotenoid and lycopene concentrations in skin tissue.
