A science journalist's provocative exploration of how biology, psychology, media, and culture come together to shape our ongoing obsession with our bodies, while also tackling the myths and realities of the "obesity epidemic."

It's not a scientific truth that has come into question lately but the truth--the very notion of scientific truth. Bringing a reasonable voice to the culture wars that have sprung up around this notion, this book offers a clear and constructive response to those who contend, in parodies, polemics and op-ed pieces, that there really is no such thing as verifiable objective truth--without which there could be no such thing as scientific authority. A distinguished physicist with a rare gift for making the most complicated scientific ideas comprehensible, Roger Newton gives us a guided tour of the intellectual structure of physical science. From there he conducts us through the understanding of reality engendered by modern physics, the most theoretically advanced of the sciences. With its firsthand look at models, facts, and theories, intuition and imagination, the use of analogies and metaphors, the importance of mathematics (and now, computers), and the "virtual" reality of the physics of micro-particles, The Truth of Science truly is a practicing scientist's account of the foundations, processes, and value of science. To claims that science is a social construction, Newton answers with the working scientist's credo: "A body of assertions is true if it forms a coherent whole and works both in the external world and in our minds." The truth of science, for Newton, is nothing more or less than a relentless questioning of authority combined with a relentless striving for objectivity in the full awareness that the process never ends. With its lucid exposition of the ideals, methods, and goals of science, his book performs a great feat in service of this truth.

A Pollan-esque look at the truth about wheat, with surprising insights on the advantages of eating the world’s most contested grain You owe it to your mind and body to step away from the gluten-free frenzy long enough to do what’s best for your own personal health. Once you separate fad from fact you’ll quickly discover the answer: whole grains, including wheat. Most recently, a Harvard School of Public Health long-term study that followed 117, 500 men and women over a 25-year span revealed that people who eat a whole grain-rich diet lower their risk of cardiovascular disease by 20 percent, and increase their lifespan at least 6 percent. No other food produces similar results. As for the gluten found in wheat, rye and barley—at most six out of a hundred of us have any real problem with it, and less than one percent of us, with celiac disease, cannot tolerate it in any form. So why has wheat become the new asbestos? Why are the shelves of every grocery store and supermarket in America heaped high with gluten-free products? That’s what Stephen Yafa sets out to discover in Grain of Truth—a book drawn in part from personal experience that is as entertaining as it is informative. After hundreds of interviews with food scientists, gluten-sensitive individuals, bakers, nutritionists, gastroenterologists and others, he finds that indeed there is indeed a culprit. But it’s not wheat. It’s not gluten. It’s the way that grain is milled and processed by large industrial manufacturers and bakeries. That discovery spurs him to search out growers, millers and bakers who deliver whole wheat to us the way it was meant to be: naturally fermented, with all parts, bran, germ, and white endosperm intact. Yafa finds a thriving local grain movement gaining strength across the country, much as the organic movement did a few decades back. And as he apprentices with local artisan bakers and make his own sourdough breads at home he learns something that few of us know: naturally fermented over two days, as opposed to four hours in commercial bakeries, whole wheat is easily digested by the vast majority of us, including many who consider themselves gluten-sensitive. The long fermentation processing method breaks down these bulky gluten proteins into tiny fragments while slowing the conversion rate of starch to sugar in our bloodstream. Along the way Grain of Truth challenges many common myths. Yafa shows us the science that proves a gluten-free diet doesn’t lead to weight loss and that it isn't healthier in any way. He counters common assumptions that modern wheat has been genetically manipulated to contain more gluten, and he point out that despite much web chatter to the contrary, there is no GMO wheat. Those are only some of the reasons that Grain of Truth offers a badly needed fact-based response to anti-wheat hysteria. It also offers an ingredient in short supply these days—common sense, measured out with just enough savvy and substance to make you reconsider what's best for you—and to help you find a healthy answer in real, delicious food. For readers of Salt Sugar Fat and The Omnivore’s Dilemma, Grain of Truth smoothly blends science, history, biology, economics, and nutrition to give us back our daily bread.

"In The Truth about Food, one of the world's leading authorities on lifestyle medicine, health promotion, and the prevention of chronic disease lays out not just what he knows about diet and health, but how and why he knows it. This book uniquely empowers readers to benefit from what's fundamentally and reliably true - while setting us all free from fads, false claims, and distractions by showing how to differentiate truth from the exploitative "lies" that abound. This book would be much shorter if it only detailed what we know to be true today. It shows how to keep up with new findings, too, and most importantly- how never to be duped again. Based on science, informed by uncommon sense, and aligned with the global consensus of diverse experts, The Truth about Food is an invitation to add years to your life and life to your years; to love the food that loves you back for a lifetime; and to enjoy the comforting confidence that only comes from genuine understanding."--Publisher's description.

How did the universe begin? Can God's existence be proven? Do humans matter more than animals? For many years people have sent the scientist-turned-priest John Polkinghorne these and other questions about science and belief. In question-and-answer format, Polkinghorne and his collaborator Nicholas Beale offer their highly informed opinions about some of the most frequently asked of these questions. Readers can follow their own paths through the book, selecting questions that interest them and looking at the additional material if they choose. This unique book will help Christians clarify their beliefs regarding difficult issues and better face challenges--from within and from others--to their faith.

Never before have we had so much information available to us about food and health. There’s GAPS, paleo, detox, gluten-free, alkaline, the sugar conspiracy, clean eating... Unfortunately, a lot of it is not only wrong but actually harmful. So why do so many of us believe this bad science? Assembling a crack team of psychiatrists, behavioural economists, food scientists and dietitians, the Angry Chef unravels the mystery of why sensible, intelligent people are so easily taken in by the latest food fads, making brief detours for an expletive-laden rant. At the end of it all you’ll have the tools to spot pseudoscience for yourself and the Angry Chef will be off for a nice cup of tea – and it will have two sugars in it, thank you very much.

In this wide-ranging book, one of the boldest thinkers in modern neuroscience confronts an ancient philosophical problem: can we know the world as it really is? Drawing on provocative new findings about the psychophysiology of perception and judgment in both human and nonhuman primates, and also on the cultural history of science, Jean-Pierre Changeux makes a powerful case for the reality of scientific progress and argues that it forms the basis for a coherent and universal theory of human rights. On this view, belief in objective knowledge is not a mere ideological slogan or a naive confusion; it is a characteristic feature of human cognition throughout evolution, and the scientific method its most sophisticated embodiment. Seeking to reconcile science and humanism, Changeux holds that the capacity to recognize truths that are independent of subjective personal experience constitutes the foundation of a human civil society.

The United States spends greatly more per person on health care than any other country but the evidence shows that care is often poor and inappropriate. Despite expenditures of 1.7 trillion dollars in 2003, and growing substantially each year, services remain fragmented and poorly coordinated, and more than 46 million people are uninsured. Why can't America, with its vast array of resources, sophisticated technologies, superior medical research and educational institutions, and talented health care professionals, produce higher quality care and better outcomes? In The Truth about Health Care, David Mechanic explains how health care in America has evolved in ways that favor a myriad of economic, professional, and political interests over those of patients. While money has always had a place in medical care, "big money" and the quest for profits has become dominant, making meaningful reforms difficult to achieve. Mechanic acknowledges that railing against these influences, which are here to stay, can achieve only so much. Instead, he asks whether it is possible to convert what is best about health care in America into a well functioning system that better serves the entire population. Bringing decades of experience as an active health policy participant, researcher, teacher, and consultant to the public and private sectors, Mechanic examines the strengths and weaknesses of our system and how it has evolved. He pays special attention to areas often neglected in policy discussions, such as the loss of public trust in medicine, the tragic state of long-term care, and the relationship of mental health to health care. For anyone who has been frustrated by uncoordinated health networks, insurance denials, and other obstacles to obtaining appropriate care, this book will provide a refreshing and frank look at the system's current and future dilemmas. Mechanic's thoughtful roadmap describes how health plans, healthcare professionals, policymakers, and consumer groups can work together to improve access, quality, fairness, and health outcomes in America.
