Tips
17.5 kcal: it is one of the least energy-dense foods in our database. It is 94.6 g of water per 100 g. It fills the plate for almost nothing, and that is its whole value in a meal.
19.9 mg of vitamin C: a 130 g tomato provides 26 mg. That is a third of the reference intake, which is not negligible for a food eaten so often.
Lycopene is more available cooked than raw. This is one of the rare cases where cooking increases the value of a vegetable: a simmered sauce releases far more than a salad.
Never in the fridge. Below 12 °C, the aromas break down irreversibly. This is the main reason shop tomatoes have no taste, more so than the variety itself.
Picked ripe, it is a different thing. Seasonal tomatoes bought at the market do not have the same sugar or aroma content as those picked green. The figures in the table do not reflect this gap.
