Current scientific evidence suggests that free radicals— unstable by-products produced by normal human metabolic processes—damage the body, resulting in chronic health disorders and degenerative changes associated with aging. Nutritional products on the market today promise antioxidants can reduce—possibly even reverse—damage caused by these free radicals. If true, that would mean less chronic disease and premature aging, at the very least. But are antioxidants indeed the new Fountain of Youth? Media reports extol antioxidants as the solution to disease and aging, and some studies do seem to back up those reports. Yet the studies that have been completed are far from conclusive, and taking antioxidant supplements can be dangerous. This book explores current thinking, analyzes studies, and answers the questions: What are antioxidants? What do they do? Is there any real benefit to taking them as supplements? Are there real dangers for me?Media report preliminary and conflicting scientific studies on antioxidants, notwithstanding the fact that the final analysis about their effectiveness and safety is incomplete. The result is increasing sales of dietary supplements and so-called functional foods or nutraceuticals that are not regulated, nor proven, and a possible public safety crisis from hypersupplementation. Milbury and Richer bring us up to date, sharing nuances and emerging news regarding antioxidants—and their dangers. Understanding the Antioxidant Controversy is an educated consumers' and health professionals' guide to this controversial topic.

Most people take eating for granted - but for some, eating can be downright dangerous. Thirty thousand Americans are hospitalized each year due to an allergic food reaction and peanut allergies in American children doubled from 1997 to 2002. Between two and ten percent of children are affected by food allergies worldwide and adverse food reactions increased hospital admissions by five hundred percent in the United Kingdom during the past two decades. Asthma cases, a reliable indicator of food allergy susceptibility, increased one hundred percent during the last thirty years. While most people assume they have a food allergy, only a very small percentage of cases are a true food allergy. For reasons still unknown, the human immune system reacts abnormally to certain foods. However, medical disorders, increased globalization of the food supply, and an upsurge of processed and convenience foods that contain food additives may also cause adverse food reactions as well. Accurate diagnosis can be extremely tricky and many sufferers never learn what causes their symptoms.Why are adverse food reactions on the rise? How can an accurate diagnosis be made? Is it even possible to enjoy foods and stay safe and healthy? These are just some of the questions this book will answer while helping the reader to learn all they can about why adverse food reactions happen, distinguish between a true food allergy and a food hypersensitivity, and outline strategies to successfully manage and live with them.
