Tomatoes

The tomato is the world's most popular fruit.

Tomatoes are rich in vitamins A and C and fibre, and are cholesterol free. An average size tomato (148 gram, or 5 oz) boasts only 35 calories. Furthermore, new medical research suggests that the consumption of lycopene - the stuff that makes tomatoes red - may prevent cancer.

Cooked tomatoes have higher concentrations of lycopene than non-cooked tomatoes.
