LONDON (Metro): Some say the secret to good health is exercise, others a good night’s sleep. But for Susan Reynolds, who has gone without a hot dinner for seven years, it’s her raw food diet. She claims her strict regime of uncooked fruit, vegetables, grains, seeds, nuts and beans is the reason for her amazing health - and the fact she can pass for a 16-year-old. The yoga teacher, who is 29, admits she loved ‘all you can eat’ Chinese meals and McChicken Sandwiches as a student but a trip to India when she was 21 changed everything.
