Millions of people worldwide are exposed to arsenic from contaminated water, and we are all exposed to arsenic via the food we eat. New research published in BioMed Central's open access journal Nutrition Journal has demonstrated that people who ate more dietary vitamin B12 and animal protein had lower levels of arsenic (measured by deposition in toenails). Total dietary fat, animal fat, vegetable fat and saturated fat were also all associated with lower levels of arsenic, while omega 3 fatty acids, such as those found in fish oil, were associated with increased arsenic. http://medicalxpress.com/news/2012-06-arsenic-overload.html Health Thu, 28 Jun 2012 20:00:02 EST news260124253 The Council for Responsible Nutrition (CRN), the dietary supplement industry's leading trade association, today released its comprehensive report, The Benefits of Nutritional Supplements (4th Edition). The updated book, which assesses the current state of the science on the health benefits associated with select nutritional supplements, finds consistent and adequate use of these products contributes to overall health and wellness throughout all age groups, lifestyles, and life stages. http://medicalxpress.com/news/2012-06-crn-current-state-scientific-nutritional.html Health Wed, 20 Jun 2012 14:56:11 EST news259422938 Older people who take omega-3 fish oil supplements are probably not reducing their chances of losing cognitive function, according to a new Cochrane systematic review. Based on the available data from studies lasting up to 3.5 years, the researchers concluded that the supplements offered no benefits for cognitive health over placebo capsules or margarines, but that longer term effects are worth investigating. http://medicalxpress.com/news/2012-06-role-omega-cognitive-decline-older.html Health Tue, 12 Jun 2012 19:00:12 EST news258745473 (HealthDay) -- People with type 2 diabetes who take omega-3 fatty acid supplements are neither helping nor harming their heart, a new study finds. http://medicalxpress.com/news/2012-06-fish-oil-wont-diabetics-hearts.html Diabetes Mon, 11 Jun 2012 17:30:01 EST news258653360 For the first time, researchers at the University of California, San Diego have peered inside a living mouse cell and mapped the processes that power the celebrated health benefits of omega-3 fatty acids. More profoundly, they say their findings suggest it may be possible to manipulate these processes to short-circuit inflammation before it begins, or at least help to resolve inflammation before it becomes detrimental. http://medicalxpress.com/news/2012-05-omega-oils-cellular-possibility-boosting.html Medical research Tue, 15 May 2012 13:52:33 EST news256308736 Among patients with new synthetic arteriovenous grafts (a synthetic tube grafted between an artery and vein) for vascular access for hemodialysis, daily ingestion of fish oil did not decrease the proportion of grafts with loss of patency (remaining open) within 12 months, according to a study in the May 2 issue of JAMA. However, fish oil recipients had a longer time without thrombosis (formation of a blood clot), half the thrombosis rate, and a clinically meaningful reduction in frequency of radiological and surgical interventions. http://medicalxpress.com/news/2012-05-fish-oil-supplements-significantly-failure.html Diseases, Conditions, Syndromes Wed, 02 May 2012 06:40:01 EST news255158290 Over the past decade, there has been a steady stream of information promoting the health benefits of fish oil capsules.

To evaluate whether fish oil supplementation could be an adjunct therapy for periodontitis, Dr. Alison Coates from the University of South Australia and colleagues from the School of Dentistry at University of Adelaide in Australia reviewed evidence from eight unique studies that involved humans. http://medicalxpress.com/news/2012-04-fish-oil-therapy-periodontal-disease.html Dentistry Tue, 24 Apr 2012 16:31:33 EST news254503832 Over the past three decades, researchers have firmly established that the omega-3 fatty acids in fish oil, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have healthy effects on the heart. Omega-3 fatty acids seem to help both in preventing cardiovascular disease as well as in preventing future heart attacks, strokes, and other adverse events in people who have established cardiovascular disease. These findings have been so strong that the American Heart Association now recommends eating fish or taking fish oil as a preventive measure both for healthy individuals and those with cardiovascular disease. However, the mechanism behind omega-3's healthy effects isn't yet known. http://medicalxpress.com/news/2012-04-omega-fatty-acids-dont-heart.html Cardiology Tue, 24 Apr 2012 16:24:19 EST news254503413 (HealthDay) -- Taking omega-3 fatty acid supplements won't protect against repeat heart attacks, strokes or other cardiovascular problems, a new analysis indicates. http://medicalxpress.com/news/2012-04-omega-supplements-heart.html Cardiology Mon, 09 Apr 2012 16:23:11 EST news253207367 Many consumers want to increase their intake of heart-healthy n-3 fatty acids, found naturally in fish and fish products, but find it difficult to consume the levels recommended by the American Heart Association. Scientists at Virginia Tech have demonstrated that it may be possible to achieve the suggested daily intake in a single serving of a savory-flavored yogurt, providing an easily incorporated dietary source for these valuable fatty acids. Their work is detailed in the April issue of the Journal of Dairy Science. http://medicalxpress.com/news/2012-03-fish-oil-added-yogurt-consumers.html Health Wed, 28 Mar 2012 11:51:31 EST news252154285 Fish oil is an underused ingredient in the food industry because of its association with a strong odor and aftertaste. A new study in the February issue of the Journal of Food Science, published by the Institute of Food Technologists, shows that fish oil can be added to goat cheese to deliver high levels of heart-healthy omega-3 fatty acids without compromising taste or shelf-life. http://medicalxpress.com/news/2012-02-food-scientists-fortify-goat-cheese.html Health Thu, 16 Feb 2012 13:09:33 EST news248620162 Researchers at Zucker Hillside Hospital's Recognition and Prevention (RAP) Program who have worked with teenagers at risk for serious mental illness for the past decade are now studying the effectiveness of Omega 3 fatty acids (fish oil) for treating psychiatric symptoms. This new study is a National Institute of Mental Health-funded randomized double-blind trial that was designed to test whether Omega-3 fatty acids improve clinical symptoms, and help adolescents and young adults (ages 12 to 25) who are at elevated risk for severe psychiatric disorders function better in school, work and other social environments. http://medicalxpress.com/news/2012-02-fish-oil-psychiatric-disorders.html Health Wed, 08 Feb 2012 12:24:37 EST news247926267 (Medical Xpress) -- Research from Queen Mary, University of London suggests that omega-3 fatty acids, which are found in fish oil, have the potential to protect nerves from injury and help them to regenerate. http://medicalxpress.com/news/2012-01-omega-fatty-acids-nerve.html Medical research Wed, 11 Jan 2012 09:05:18 EST news245495111 Is obesity in infants "programmed" in the womb? Previously, researchers assumed that consumption of "bad" fats during pregnancy contribute to excessive infant adipose tissue growth and that "good" omega-3 fatty acids prevent expansive adipose tissue development. An study run by the Technische Universität München showed no evidence to support this "perinatal programming" theory. http://medicalxpress.com/news/2012-01-fish-oil-pregnancy-excessive-adipose.html Obstetrics & gynaecology Wed, 04 Jan 2012 13:56:09 EST news244907760 A compound produced from fish oil that appears to target leukemia stem cells could lead to a cure for the disease, according to Penn State researchers.
