Um estudo confirma (apesar do mecanismo ainda não estar bem compreendido) a acção benéfica do licopeno (presente no tomate, ketchup) mesmo em suplementos:

Citando:
"A substance found in tomatoes relieves impairment of blood vessels, which may explain why people who eat a Mediterranean diet have a notably reduced incidence of cardiovascular disease, according to a study.

A supplement of lycopene, a powerful antioxidant which is 10 times more potent than vitamin E, improved and normalised function of the endothelium (the inner lining of blood vessels) in volunteers with cardiovascular disease, researchers from the University of Cambridge found."
(...)
Lycopene is found in tomatoes and its potency appears to be enhanced when it is consumed pureed, in ketchup or in the presence of olive oil. It is also found in other fruit and vegetables, such as grapefruit, watermelon, asparagus and carrots."
