Nearly 85 percent of seafood enjoyed by U.S. consumers is imported, and almost half of that is farm raised through a process called "aquaculture," according to the National Aquaculture Association, based in Pine Bluff, Arkansas. In 2011, the United States imported $16.6 billion of seafood and exported $5.4 billion, a difference of $11.2 billion. http://phys.org/news287737719.html Biology Tue, 14 May 2013 08:10:35 EST news287737719 Dairy cows that are fed flaxseed produce more nutritious milk, according to a new study by Oregon State University. http://phys.org/news278354769.html Biology Fri, 25 Jan 2013 16:46:34 EST news278354769 A genetic mutation that occurred thousands of years ago might be the answer to how early humans were able to move from central Africa and across the continent in what has been called "the great expansion," according to new research from Wake Forest Baptist Medical Center. http://phys.org/news267290115.html Biology Wed, 19 Sep 2012 17:00:16 EST news267290115 For generations, the consumption of dairy products has been positively associated with the health and wellness of families and communities. Nevertheless, the recent shift in dietary trends has focused on "what not to eat" instead of emphasizing "what to eat," resulting in demonizing the naturally occurring fats in dairy, while overlooking its many essential nutrients. http://phys.org/news216581061.html Medicine & Health Thu, 10 Feb 2011 17:24:40 EST news216581061 (PhysOrg.com) -- The discovery by UCLA biochemists of a new method for preventing oxidation in the essential fatty acids of cell membranes could lead to a new class of more effective nutritional supplements and potentially help combat neurodegenerative disorders such as Parkinson's disease and perhaps Alzheimer's. http://phys.org/news210494268.html Chemistry Thu, 02 Dec 2010 06:38:17 EST news210494268 Although some data have suggested that omega-3 fatty acid supplements, such as from fish oil, may improve treatment of atrial fibrillation, a randomized trial with more than 600 patients finds that treatment with high-dose prescription omega-3 did not reduce the recurrence of atrial fibrillation over six months, according to a study that will appear in the December 1 issue of JAMA. The study is being released early online because it will be presented at the American Heart Association's annual meeting. http://phys.org/news209039156.html Medicine & Health Mon, 15 Nov 2010 11:00:04 EST news209039156 In contrast to the findings of some studies and the recommendations that pregnant women increase their intake of fish oil via dietary docosahexaenoic acid (DHA) because of the possible benefits, a randomized trial that included more than 2,000 women finds that use of DHA supplements did not result in lower levels of postpartum depression in mothers or improved cognitive and language development in their offspring during early childhood, according to a study in the October 20 issue of JAMA. http://phys.org/news206726818.html Medicine & Health Tue, 19 Oct 2010 17:07:13 EST news206726818 The researchers decoded a complete cascade of signals within breast tumour cells activated by virgin olive oil, and concluded that benefits include decrease in the activity of the oncogene p21Ras, changes in protein signaling pathways, stimulation of tumour cell death and prevention of DNA damage. The study was carried out in an experimental model and researchers have already begun a new study with human cell lines. http://phys.org/news197117236.html Medicine & Health Wed, 30 Jun 2010 13:50:01 EST news197117236 Eating three or more burgers a week may boost a child's risk of asthma and wheeze - at least in developed nations - reveals a large international study, published in Thorax today. http://phys.org/news194726486.html Medicine & Health Wed, 02 Jun 2010 19:42:00 EST news194726486 Scientists from The Scripps Research Institute have created a novel technique that for the first time will allow the efficient production of a molecular structure that is common to a vast array of natural molecules.

The study also found significantly higher plasma monounsaturated fatty acids in the blood of patients with NAFL and NASH. Full findings appear in the December issue of Hepatology. http://phys.org/news178265314.html Medicine & Health Tue, 24 Nov 2009 06:40:01 EST news178265314 Experts estimate that over 24 million people worldwide suffer from dementia, and many of these people live in low- and middle-income countries.

Scientists at the Research Institute of Wildlife Ecology in Austria have shown that an equivalent improvement can be achieved in mice by feeding them a diet high in a certain type of polyunsaturated fatty acid. Dr. Christopher Turbill will present the research at the Society for Experimental Biology meeting on Monday, June 29. http://phys.org/news165474068.html Biology Mon, 29 Jun 2009 06:01:59 EST news165474068 Regularly eating fish, nuts, olive oil and other foods containing omega-three fatty acids and avoiding trans fats appears to be associated with a lower risk for the eye disease age-related macular degeneration, according to two reports in the May issue of Archives of Ophthalmology. http://phys.org/news161278809.html Medicine & Health Mon, 11 May 2009 16:41:28 EST news161278809 One year after giving birth, women were less likely to have the most dangerous kind of obesity if they had been given probiotics from the first trimester of pregnancy, found new research that suggests manipulating the balance of bacteria in the gut may help fight obesity. http://phys.org/news160896630.html Medicine & Health Thu, 07 May 2009 06:31:14 EST news160896630
