A 12-year study led by Dr Edward Giovannucci of the Harvard Medical School promotes the argument that lycope can help ward off breast cancer and osteoporosis. The news has been received with pleasure by manufacturers of tomato ketchup, as this is a good source of lycopene. Giovannucci said: “Ketchup is an ideal source of lycopene, because it contains high concentrations of the compound, due to thermal processing used in its manufacturing. Tomato sauce captures most of the lycopene.”
