Eating reheated spaghetti bolognese could reduce your risk of cancer.
Scientists have discovered that multiple rounds of heating - plus a little extra oil - enhance the health benefits of processed tomatoes.
The technique alters the structure of the tomato molecule lycopene so that it is more easily transported into the bloodstream.
Lycopene, a powerful antioxidant, has been shown to prevent cancers and may also combat heart disease and diabetes.
