Are plant-based diets environmentally friendly?
NEW YORK (Reuters Health) - A nutritious diet that includes lots of fruits and vegetables might not be the greenest in its environmental impact, according to a new study from France. After analyzing the eating habits of about 2,000 French adults, and the greenhouse gas emissions generated by producing the plants, fish, meat, fowl and other ingredients, researchers concluded that widely embraced goals for the health of people and for the health of the planet are not necessarily perfectly compatible.
FDA outlines path to test Alzheimer's drugs earlier
CHICAGO (Reuters) - Proposed U.S. guidelines may make it easier for drug companies to test Alzheimer's treatments in people at an earlier stage, when scientists think they may have the best shot at working. The draft guidance document, issued on Thursday by the U.S. Food and Drug Administration, reflects changes in scientists' understanding of Alzheimer's.

WASHINGTON (Reuters) - U.S. Roman Catholic bishops on Thursday rejected the Obama Administration's latest bid for compromise over a hotly disputed health policy that requires employees at religiously affiliated institutions to have access to insurance coverage for contraceptives.

U.S. rejects Mississippi health insurance exchange plan
JACKSON, Mississippi (Reuters) - Mississippi on Friday became the first state to have its proposal for a health insurance exchange rejected by the U.S. government, and federal officials said Republican Governor Phil Bryant's opposition to the plan was to blame. "With a lack of support from your governor and no formal commitment to coordinate from other state agencies, we do not see a feasible pathway to conditionally approving a state-based exchange in Mississippi for 2014," the U.S. Department of Health and Human Services said in a letter to the state.
No sign that omega-3s benefit babies' brains
NEW YORK (Reuters Health) - A review of the existing evidence finds it to be inconclusive about whether omega-3 fatty acids taken by mothers during pregnancy boost their kids' brain development early in life. "There are so many trials where pregnant women are supplemented with omega-3 fatty acids and they've all got different results," said lead study author Jacqueline Gould, a researcher at the Women's and Children's Health Research Institute in Adelaide, Australia. "We found that there was neither a positive nor a negative effect on visual or neurological outcomes."

WASHINGTON (Reuters) - Exports of U.S. pharmaceuticals to Iran were cut in half last year, according to data released on Friday, while overall U.S. exports to the Islamic republic rose about nine percent because of grain sales.

Psychiatric drugs tied to falls in the elderly
NEW YORK (Reuters Health) - Seniors taking psychiatric drugs may be at extra high risk for falling, new Dutch research suggests.

Britain condemns "criminal" horsemeat scandal
LONDON (Reuters) - The British government accused unknown criminals for a growing scandal of horsemeat being sold in imported beef products that has generated shock headlines in a country where many recoil in horror at the very idea of eating horses. Prime Minister David Cameron assured consumers on Friday there was no health risk from a product considered a delicacy in France and Italy. But, as the furor saps public confidence in food labeling and hygiene supervision, he called it "completely unacceptable", and his office condemned "acts of criminality".
