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. No investigations specifically measured the effect of tomato / tomato-based foods or lycopene on weight loss or weight management endpoints. However, adults and children who have a higher body mass index or who have greater fat mass tend to have lower concentrations of plasma carotenoids and lycopene. These findings may reflect dietary patterns and or absorption or metabolic insufficiencies in overweight and obese individuals compared to healthy weight individuals. Research on dietary lycopene intake, supplementation and tomato-specific intake on body weight management and obesity-associated metabolic endpoints will expand the understanding of this relationship.
