Join best-selling author Michael Pollan (Food Rules, The Botany of Desire) on a fascinating journey to answer the question: What should I eat to be healthy? Cutting through confusion and busting myths and misconceptions, In Defense of Food shows how common sense and old-fashioned wisdom can help us rediscover the pleasures of eating and avoid the chronic diseases so often associated with the modern diet. Pollan's journey of discovery takes him from the plains of Tanzania, where one of the world's last remaining tribes of hunter-gatherers still eats the way our ancestors did, to Loma Linda, California, where a group of Seventh Day Adventist vegetarians live longer than almost anyone else on earth, and eventually to Paris, where the French diet, rooted in culture and tradition, proves surprisingly healthy. Along the way he shows how a combination of faulty nutrition science and deceptive marketing practices have encouraged us to replace real food with scientifically engineered "food-like substances." And he explains why the solution to our dietary woes is in fact remarkably simple: Eat Food. Not Too Much. Mostly Plants.
Horizon investigates a new era of Alzheimer's research, which is bringing hope to millions of sufferers across the world. New scanning and gene technology is allowing scientists to identify the disease at its earliest stages, often 15 years before symptoms appear and the brain cells are destroyed. A series of new drugs trials in Colombia, the USA and Europe are showing startling success in reducing beta amyloid, the protein which is a hallmark of the disease. It is also becoming clear that changes in lifestyle can prevent the development of the disease. A new system inside the brain has been discovered which clears amyloid when we are in deep sleep, but allows it to accumulate if we don't sleep well. The programme reveals that for sufferers in the early stages of the disease, brain connections, or synapses, can be strengthened and even replaced by absorbing enough of the right nutrients. A UK-wide trail helps sufferers in the early stages to concentrate on improving everyday tasks, and in the process not only make their lives easier, but helps to reactivate the planning and organisational parts of the brain. In an ageing world, where the biggest risk of developing Alzheimer's is old age, the scientific breakthroughs in Alzheimer's disease are bringing hope where once there was despair.
Angela Rippon investigates the disease that took her mother's life and is now starting to affect her friends. She undergoes a series of tests to discover if she has any early signs of the disease and makes the difficult decision about whether to take a genetic test that could predict her future risk. Along the way, Angela finds out some of the surprising ways people can help to protect themselves. She discovers why getting a good night's sleep could help prevent Alzheimer's and how learning a new language might be more effective than any current drug treatment. Angela also visits a number of people who are living with the disease, including Bob, the husband of one of her oldest friends. She meets families that carry a gene for early-onset Alzheimer's and discovers how they could be the best hope of finding a cure for this devastating disease.
