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.

Food Choices focuses on how the food we consume affects not only our personal health, but that of the entire planet. Filmmaker Michael Siewierski takes an in-depth look at how the consumption of animal products has a long-lasting, negative effect on the earth’s biosphere. Not only does he report on facts relating to the unethical treatment of animals raised for human consumption, but he also addresses the addition of genetically modified organisms (GMOs) and antibiotics to animal feed. This trickle-down effect results in the poisoning of both our bodies and the planet.

Fresh or processed, white or red - how does meat measure up? It's been getting a lot of bad press recently with new links to cancer and heart disease. But 98 per cent of us in the UK are still meat eaters. Chris Bavin, a greengrocer by trade and a carnivore by nature, wants to know if he can keep meat in his diet and stay healthy. He teams up with top scientists to put meat under the microscope and examine it as never before. They follow 40 volunteers on a groundbreaking study to find out exactly how much meat is good for us, test whether paying more for chicken makes it any better for us, discover a way to dramatically reduce the health risks associated with processed meats and reveal an unlikely lean supermeat that won't break the bank.

100 years ago a new word in medicine was invented: “vitamin". This year the world will spend over $100 billion on vitamins and supplements. Dr. Derek Muller takes us on a world-spanning investigation of vitamin science and history, asking how do we decide whether to take vitamin supplements or not?
