Omega Fatty Acid Balance Can Alter Immunity And Gene Expression
For the past century, changes in the Western diet have altered the consumption of omega-6 fatty acids (w6, found in meat and vegetable oils) compared with omega-3 fatty acids (w3, found in flax and fish oil). Many studies seem to indicate this shift has brought about an increased risk of inflammation (associated with autoimmunity and allergy), and now using a controlled diet study with human volunteers, researchers may have teased out a biological basis for these reported changes.

A Prospective fMRI Study Of Dopamine-Related Activity Of Food Reward Circuits In The Brain And Weight Gain
Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), July 28 - August 1, 2009, the foremost society for research into all aspects of eating and drinking behavior, finds that women who possess genetic modifications associated with low activity of the reward neurotransmitter dopamine in the brain when they imagine eating appetizing foods are more prone to weight gain. Functional Magnetic Resonance Imaging (fMRI) scans of brain activity revealed that women who had lower activity in food reward regions of the brain and who had genetic modifications associated with lower dopamine activity showed the greatest weight gain after one year. Eric Stice from the Oregon Research Institute says, "These findings provide some of the first prospective evidence that people who experience blunted reward from food may compensate by overeating, increasing risk for unhealthy weight gain." Overconsumption of appetizing foods may occur in an attempt to increase brain reward in less responsive systems. The results of this study highlight the need for further research into the role that neural reward systems play in the development of obesity. "It may be useful for individuals who show low food-related reward to increase their physical activity, which not only promotes activity the same reward circuitry but also reduces unhealthy weight gain from overeating" says Stice.

Washington Post Examines Future Of USAID, Foreign Policy Reports Farmer No Longer Under Consideration For Agency Top Spot

USAID, "the main U.S. foreign aid agency is in limbo, entering its seventh month without a permanent director despite pledges by the Obama administration to expand development assistance and improve its effectiveness in poor countries," the Washington Post reports in an article examining the agency"s prospects and concerns that changes could reduce its clout. "While [Secretary of State Hillary Rodham] Clinton has championed additional personnel for USAID, aid groups worry that the once-autonomous agency could be swallowed up in the State Department, with long-term development goals losing out to short-term political aims," the Washington Post writes. The article includes comments from development experts and administration officials on USAID"s future. According to the Washington Post, some development experts believe the top candidate for heading up USAID "in recent weeks appeared to be Paul Farmer, a charismatic doctor who has built hospitals for the poor in Haiti, Rwanda and other countries (Sheridan, 8/5). However, Foreign Policy"s blog, "The Cable," reports that "[s]everal Hill and Washington foreign policy hands" are saying that Paul Farmer, the cofounder of Partner in Health, is no longer being considered to lead USAID. The decision "was said to have been made at the White House," according to the blog. "Given his resume ... [working] to bring health care to the poor in Haiti, Peru and elsewhere," Farmer was "said by an associate and an administration official to have been daunted by the vetting paperwork for the prospective job, including a form requiring him to list every foreigner he had come into contact with the past several years. But it wasn"t clear if Farmer ran into a snag clearing the vet, grew disillusioned with the prospective job over the process, or rather, was a victim of the complaints about the vetting process," the blog writes (Rozen, 8/4).
