Tomato's have lycopene, I have a thing for lycopene now....it's so awesome an antioxidant, they done this study I saw it on TV, that eating 50grams of tomato paste a day, within 3 months a woman prone to sunburn, developed 30% less burning in the same time, just by tomatoes!
Although, in order to get lycopene to be highly bioavailable, it has to be processed in some way, like pizza base, tomato paste, ketchup etc. Also, to eat it with fats (olive oil is best) will also incraese lycopene absorption.
I eat something tomatoey everyday, not coz I want lycopene, but coz I just do with my normal preferred diet, whether its a pasta sauce, tomato soup, I also have tons of ketchup with food when I have it.
I need a way to eat tomato paste on it's own though without it tasting so strong...I think 50grams spread over 3 crackers with some olive oil and chives or herbs might be good.
