Steph McGovern turns her attention to salt's role in our diet. She begins in Wales at the Halen Mon sea salt company, learning how they produce their salt from the waters of the Menai Straits, then moves on to learn more about the wide variety of artisan salts that have become so popular in recent years - from French Fleur du Sel to the beautiful pink Himalayan Rock Salt. She goes on to address the issue of salt and health.
