Book Description
Abstract: Introduction: The omega-3 fatty acids, eicosapentaenoic (EPA) and docosahexaenoic acid (DHA), have many health benefits such as reducing risks of heart disease, cancer and depression. EPA and DHA are found in oily fish and are also available in dietary supplements. The 2010 Dietary Guidelines for Americans recommend 1,750 mg EPA and DHA/wk, or 250 mg/day, which can be reached by consuming 8 ounces of seafood/week. For many people, achieving this recommended amount of EPA and DHA through diet alone may be difficult unless supplements are also used. Though the health benefits of fish oil are relatively clear, the content, purity and price of EPA and DHA needed for the recommended dosage is highly confusing. Purpose: To compare the content and cost of omega-3 supplements in order to assist practitioners and consumers in making choices about purchasing an omega-3 supplement. Methods: Thirteen randomly sampled dietary omega-3 supplements available in retail stores were analyzed. Oils were extracted and prepared for analysis by gas chromatography. After quantifying the levels of numerous fatty acids including EPA and DHA, a cost analysis was performed for each supplement based on retailer's list prices per unit (e.g., gram of oil), recommended dosage and composition. Results:Fish oil pills available for consumers varied greatly in content and price. The amount of DHA + EPA ranged from 10 mg/g to 894 mg/g EPA and DHA. The prices also varied from $0.03 per pill, to $1.23 per pill. USummary:U Results from these analyses should clarify confusion regarding content and price per recommended serving of fish oil supplements, while also enhancing the health and quality of life for the millions of Americans suffering from diseases that may be prevented with adequate dietary intake of omega-3 fatty acids.

Book Description
The evidence that omega-3 fatty acids are essential for human development and most helpful to achieve good health throughout life is clearly documented by Dr. Joyce Nettleton in her new book Omega-3 Fatty Acids and Health. Omega 3 fatty acids are produced by the plants of the land and sea. The tissues of the body require the omega-3 fatty acids for their proper functioning just as they also need the omega-6 essential fatty acids. It is probable in man's evolutionary development that there has always been the proper balance between these two groups of essential fatty acids, but in the modern era with the provision of inexpensive vegetable oils it is possible that the pendulum for increased dietary omega-6 fatty acids in the form of linoleic acid has swung too far and the intake ofomega-3 fatty acids has actualIy declined. In particular, the 22 carbon omega 3 fatty acid, docosahexaenoic acid, which has six double bonds, is important in the membranes of brain cells, heart muscle cells, the rods and cones of the retina and spermatozoa. Docosahexaenoic acid is found only in foods such as fish and other sea life, having been synthesized by the phytoplankton of the waters. An outright deficiency of omega-3 fatty acids has led to a number of distur bances in animals and human infants such as impaired vision, abnormalities of the electroretinogram, of the eye and various behavioral aberrations.

Book Description
This volume argues for the importance of essential nutrients in our diet. Over the last two decades there has been an explosion of research on the relationship of Omega-3 fatty acids and the importance of antioxidants to human health. Expert authors discuss the importance of a diet rich in Omega-3 Fatty acids for successful human growth and development and for the prevention of disease. Chapters highlight their contribution to the prevention and amelioration of a wide range of conditions such as heart disease, diabetes, arthritis, cancer, obesity, mental health and bone health. An indispensable text designed for nutritionists, dietitians, clinicians and health related professionals, Omega-3 Fatty Acids: Keys to Nutritional Health presents a comprehensive assessment of the current knowledge about the nutritional effects of Omega-3 fatty acids and their delivery in foods.

Book Description
Over the last several years developing human research suggests that a component of omega-3 fatty acids, long chain ones, contribute particularly to health benefits. Omega-6/3 Fatty Acids: Functions, Sustainability Strategies and Perspectives focuses on developing information on this newly recognized key component. This volume uniquely, and for the first time, focuses on sustainability of natural sources of omega-3 fatty acids variants including long chain ones, and on ways to increase their use and availability to reduce major diseases. The authors review cardiovascular disease, neurological changes and mental health and other diseases like diabetes where long chain omega-3 fatty acids play protective roles from recent human trials. Each chapter evaluates developing information on the possible mechanistic role of long chain omega-3 fatty acids. After showing their requirement and involvement in health promotion there are reviews of various sources and ways to protect and promote them. Authors provide support for the benefits and sources of long chain omega-3 fatty acids and their increased dietary intake that reduce various physical and mental illnesses. Omega-6/3 Fatty Acids: Functions, Sustainability and Perspectives is a unique and important new volume that provides the latest data and reviews to physicians who need to assess serum omega-6/3 and fatty acids to help diagnose risks and change diets and to inform industry and the scientific community with reviews of research for actions including new studies and therapies.

Book Description
EPA and DHA omega-3 fatty acids are contained in oily fish, such as salmon, lake trout, tuna and herring. These fatty acids are not essential to the diet; however, scientific evidence indicates that these fatty acids may be very beneficial in reducing Coronary Heart Disease among other things. This book brings together some of the recent studies on this important and interesting substance.

Book Description
Studies on the evolutionary aspects of diet and molecular studies included in this volume indicate that human beings evolved on a diet that was balanced in the essential fatty acids (EFA). In fact, the ratio of omega-6/omega-3 EFA was 1/1 whereas present day diets in both developed and developing countries have a much higher ratio, between 5/1 and 50/1. Additional studies show that a high ratio of omega-6/omega-3 EFA is detrimental to health and may lead to the development of chronic diseases. Improving the dietary ratio by decreasing the omega-6 fatty acids and increasing the omega-3 fatty acids is essential for brain function and for the management of cardiovascular disease, arthritis and cancer. A ratio of 4/1 or less leads to lower dosage and to the reduction of adverse effects of drugs. This volume should be of interest to a large and varied audience of researchers in academia, industry, and government; cardiologists, geneticists, immunologists, neuroscientists, and cancer specialists; as well as nutritionists, dietitians, food scientists, agriculturists, economists and regulators.

Book Description
Fish oil's universal actions and benefits make it one of the best choices for all Americans to influence their health for the better. Taking fish oil as a supplement or as part of a healthy diet, along with adequate amounts of exercise and stress reduction, can save lives, prevent disease, and reduce our healthcare requirements. In this book, we will discuss the latest science on the benefits of omega-3's and how this special molecule can benefit every organ in our body. We will also focus on how our body's innate natural protective mechanism, the inflammatory response, is hijacked by our poor diet and lifestyle choices and contributes, rather than prevents diseases of aging. We will give you the information you need to make better choices when looking for fish oil supplements and help you determine what dose of omega-3's works best for you. We hope to lead you down a road of exciting discovery, give you the tools to make better choices and help you to die young... as late as possible!
