Carpaccio of swordfish with grapefruit, celery and pine nuts Fine slices of noble fish, with a fruity and tart flavour. Olive oil, pine nuts and fish provide a favourable fatty acid spectrum: polyunsaturated ones contribute to the good condition of our joints, eyes, skin, heart and brain; monounsaturated ones "clean" the so-called bad cholesterol from the blood vessels, which then cannot be deposited for arteriosclerosis.
