In his midtwenties, Dave Asprey was a successful Silicon Valley multimillionaire. He also weighed 300 pounds, despite the fact that he was doing what doctors recommended: eating 1,800 calories a day and working out 90 minutes a day, six times a week. When his excess fat started causing brain fog and food cravings sapped his energy and willpower, Asprey turned to the same hacking techniques that made his fortune to "hack" his own biology, investing more than $300,000 and 15 years to uncover what was hindering his energy, performance, appearance, and happiness. From private brain EEG facilities to remote monasteries in Tibet, through radioactive brain scans, blood chemistry work, nervous system testing, and more, he explored traditional and alternative technologies to reach his physical and mental prime. The result? The Bulletproof Diet, an anti-inflammatory program for hunger-free, rapid weight loss and peak performance. The Bulletproof Diet will challenge--and change--the way you think about weight loss and wellness. You will skip breakfast, stop counting calories, eat high levels of healthy saturated fat, work out and sleep less, and add smart supplements. In doing so, you'll gain energy, build lean muscle, and watch the pounds melt off. By ditching traditional "diet" thinking, Asprey went from being overweight and sick in his twenties to maintaining a 100-pound weight loss, increasing his IQ, and feeling better than ever in his forties. The Bulletproof Diet is your blueprint to a better life.
You are what you eat. Food and diet have an enormous influence on your health and well-being, but eating the right amount of the right things - and not too much of the wrong things - isn't easy. But, as in most walks of life, knowledge is power. This book will empower you to eat healthily, lose weight, and sort the fads from the science facts. This is the New Scientist take on a "New Year, New You" book: an eye-opening and myth-busting guide to everything from sugar to superfoods, from fasting to eating like a caveman and from veganism to your gut microbiome. Forget faddy diet books or gimmicky exercise programs, this is what is scientifically proven to make you live longer and to be healthier and happier.
Terrors of the Table is an absorbing account of the struggle to find the necessary ingredients of a healthy diet, and the fads and quackery that have always waylaid the unwary and the foolish when it comes to the matter of food and health. Walter Gratzer tells the tale of nutrition's heroes, heroines and charlatans with characteristic crispness and verve. We find an array of colourful personalities, from the distinguished but quarrelsome Liebig, to the enterprising Lydia Pinkham. But we also find the slow recognition that the lack of vital ingredients can cause terrible illnesses - scurvy, rickets, beriberi. These diseases stalked the poor in the West even into the 20th century, and scandalously remain in poorer parts of the world today. The narrative stretches from classical times to the modern day and gives a valuable historical perspective to our current understanding. It also highlights some of the problems faced by the developed world regarding health today - in particular diabetes and obesity. And despite our far greater understanding of what our body needs, there are still many who would fall for fads and fancy diets - some dangerous, others just daft. Of course, the story of nutrition does not end there. We have discovered the key vitamins and minerals our body needs, but research continues on the connections between diet, health and disease. The body's biochemistry is complex, and there are no easy answers, no magic formula, that applies to all individuals. The safest and most rational course would seem to be a sensible, moderate, and varied diet, not forgetting that 'a little of what you fancy does you good'.
Vitamin E is a group of fat-soluble compounds found in a wide variety of foods. Daily requirements of vitamin E can be met with a balanced diet. High-dose supplementation may be hazardous rather than beneficial.

Vitamin E supplementation can be beneficial against coronary artery disease, eye disorders, cognitive decline, cancer, and skin aging. This book will mainly focus on the diverse functions of vitamin E, importance of vitamin E status to provide a healthy lifespan, and the interaction between vitamin E and several pathological conditions. Readers will receive a general overview of the importance of vitamin E in health and different pathological conditions.
