The recognition of oxidative stress as a major factor in health, aging, and disease has led to a surge in research aimed at uncovering effective countermeasures in the form of antioxidants. Unique in its two-fold protective function, alpha-lipoic acid has drawn unprecedented interest as a coenzyme in mitochondrial energy metabolism and as an antioxidant and cell redox modulator. Mounting data regarding its potential health benefits demands an authoritative, single-source reference to codify current knowledge and guide future research. A state-of-the-science compilation, Lipoic Acid follows the history of this potent coenzyme and the latest discoveries regarding the chemistry, biological action, and significance in energy production, antioxidant activity, and health. The book is divided into three sections: · Section I: Discovery and Molecular Structure reviews the early studies leading to the discovery of alpha-lipoic acid and explains the molecular structure, biosynthesis, and the characterization of lipoic acid and its chemical derivatives. · Section II: Metabolic Aspects describes in detail the human pharmacokinetics of alpha-lipoic acid including the lipoic acid-derived dehydrogenase complexes and their roles in energy metabolism. It also explains antioxidant activity and redox modulation and how lipoic acid induces Phase II detoxification enzymes through activation of Nrf2-dependent gene expression. · Section III Clinical Aspects discusses enzyme deficiency disorders and the effects of lipoic acid on insulin. It defines lipoic acid influence on signaling pathways and AMP-activated kinase, and considers the therapeutic implications for treatment of metabolic syndromes and the improvement of mitochondrial function by lipoic acid supplementation. Contributions from leading international researchers make Lipoic Acid the most comprehensive, up-to-date account of the impact of this potentially key molecule in diminishing the damaging effects of aging and disease.

This book is mainly based on the latest research results and applications of phenolic and polyphenolic compounds. Phenolic compounds, ubiquitous in plants, are an essential part of the human diet and are of considerable interest due to their antioxidant properties and potential beneficial health effects. These compounds range structurally from a simple phenolic molecule to complex high-molecular-weight polymers. There is increasing evidence that consumption of a variety of phenolic compounds present in foods may lower the risk of health disorders because of their antioxidant activity. When added to foods, antioxidants control rancidity development, retard the formation of toxic oxidation products, maintain nutritional quality and extend the shelf-life of products. Due to safety concerns and limitation on the use of synthetic antioxidants, natural antioxidants obtained from edible materials, edible by-products and residual sources have been of increasing interest. This contribution summarizes both the synthetic and natural phenolic antioxidants, emphasizing their mode of action, health effects, degradation products and toxicology. In addition, sources of phenolic antioxidants are discussed in detail.

Antioxidants from supplements, food sources and the environment have a cumulative effect of dangerously lowering protective prooxidant levels, which "allows" for disease manifestation and coexistence of diseases. Today's marketing of antioxidants is all about sales and has nothing to do with science-based evidence. Scientific data has shown for years that the antioxidant vitamins can increase the risk of cancer, heart disease, stroke and overall mortality. Yet, this information is ignored or denied by those "pushing" these potentially harmful products. None of the synthetic antioxidants work in the same manner as those contained in the biochemical matrix of fruits and vegetables of a nutritious diet. Today's antioxidants should be treated as medicines, not just because of their claims, but because of their proven adverse effects on the human body. I present over 250 scientific studies showing the negligible or non-existent effects of the antioxidants and of these, 80 studies highlight their wide ranging harmful effects. This is the largest collection of its kind in the world's medical literature. The hype of the antioxidants was based on the invalidated and outdated free radical theory, which lacks predictability and fails to meet the requirements of the scientific method. As was pointed out in an article entitled, Antioxidants not heaven sent, by Stefan Andrei Anghel in the Harvard Science Review, Spring 2010, "It may come as a surprise that the current scientific consensus is that there is no health benefit to taking antioxidant supplements. Even more unexpected news came this year when an article announced that antioxidants may actually prevent the health-promoting effects of physical exercise…. If the model proposed by the authors of the study is correct, then it may turn out that we have been systematically “poisoning” ourselves, increasing our disease risk and shortening our lifespan through antioxidant supplements." It was especially gratifying that Anghel cited one of my papers entitled, The Free Radical Fantasy, as the first reference in The Harvard Review and cited it two other times in the article.On January 2 5, 2011, Sharon Begley noted in Newsweek magazine in an article entitled, Antioxidants fall from grace, that, "Now the research is challenging an even more fundamental tenet of the antioxidant craze. Many of the free radicals that are neutralized by antioxidants perform valuable functions in the body. The most important: fighting toxins (white blood cells churn out free radicals by the battalion to fight bacterial infection) and fighting cancer. Maybe it's not such a fabulous idea to flood the body with something that neutralizes these warriors of the immune system." Antioxidant overuse can be dangerous with health problems, like cancer or infections. In 2009, 108 new food products with antioxidants touted on the label reached store shelves, aisles of them in the United States. Shockingly, medical personnel and cancer survivors take more antioxidants than those taken by the average person.The theory behind the use of antioxidants is plausible only if the free radical theory is sound. But, it has been nullified by hundreds of studies. The theory has been wrong and that is the reason that the antioxidant supplements available to us lack effectiveness and produce adverse effects. The free radical theory is passé!With this explanation, the American Heart Association's advisory statement is sound. There is no good reason, at this point, to spend your money on antioxidant supplements.I have endeavored to find more advanced and improved replacement theories. People are waking up to the fact that they have been victims of clever marketing campaigns, all of which were based on the profit motive.Stop being a victim while the antioxidant craze is dying down. More and more, people are becoming aware of their ineffectiveness and of their harm. The choice is yours. Choose wisely.

Dr. Howes recommends that patients should be counseled against using antioxidant supplements to prevent or treat cancer. Dr. Howes presents 118 human studies showing antioxidant ineffectiveness in cancer treatment and of this, 39 studies show harmful effects. Dr. Howes presents 27 specific human cancer cell types which are shielded by antioxidants in lab studies and 9 similar murine (rodent) studies. There are over 11 million human participants in these studies, covering over 3 decades. Over 26 studies show that the antioxidants increase the risk of cancer development and 2 studies show that the overall mortality of cancer patients taking antioxidants is increased.

Antioxidants are substances that delay or inhibit the oxidation of foods, and are therefore of great interest to food scientists. Antioxidants are naturally present in foods, but at very low levels. Therefore, additional quantities are added to control oxidation, increase shelf life, and improve overall quality. Due to the wide availability of natural antioxidants and the increasing concerns on the safety of synthetic antioxidants, the beneficial effects of natural antioxidants on the maintenance of human health have become an important topic among scientific researches worldwide. Research showed that multiple natural products including polyphenols, flavonoids, vitamins, carotenoids, polysaccharides, alkaloids and saponins could scavenge excessive free radicals in cells effectively. Searching for new antioxidants from natural products has become an inevitable trend for the modern food and medicine industries.Natural Antioxidants provides an overview of natural antioxidants, their sources, methods of extraction, regulatory aspects, and application techniques, specifically focusing on different foods of animal origin to improve their oxidative stability. The major species of natural antioxidants in foods that are benefit for the prevention and treatments of diseases have been summarized. Meanwhile, the research progress and future development have also been proposed. All of these studies, on the one hand, can provide a theoretical basis for the development of drugs and healthy foods; on the other hand, can offer novel development ideas for food industry, especially for food additive industry. The aim of this book is to conclude the progress of natural antioxidants research and provide a theoretical basis for the development of healthy food and drugs. The book serves as a comprehensive overview of the current scientific knowledge on the health effects of dietary and supplemental antioxidants. Chapters integrate information from basic research and animal studies, epidemiologic studies, and clinical intervention trials.

According to Food and Agriculture Organization (FAO) statistics, from 1970 to 2011 the world production of blueberries increased approximately 7 times (FAOSTAT, 2012). According to the National Agricultural Statistics Service (NASS) of the United States Department of Agriculture (USDA), the United States is the world leading producer of blueberries, being the second most produced and commercialised small fruit in the country after strawberry. There are three main groups of blueberries commercialised and produced in the world: the lowbush, the highbush and the Rabbiteye (RASEIRA e ANTUNES, 2004). The high amount of bioactive compounds present in both the pulp and in the peel of the blueberries, makes it a fresh fruit rich in natural antioxidants. This book discusses the harvesting methods, antioxidant properties and health effects of blueberries.
