| Easter eggs may be healthy, but only a few BRANDENBURG, Germany (UPI) -- Easter eggs -- the dark chocolate kind -- in small quantities can lower blood pressure and reduce heart disease risk, researchers in Germany found.
Study leader Dr. Brian Buijsse of the German Institute of Human Nutrition and colleagues tracked 19,357 people, ages 35-65, for at least 10 years.
The study participants -- part of the European Prospective Investigation into Cancer -- had their blood pressure checked, height and weight measurements taken and they answered questions about diet, lifestyle and health.
The study, published in the European Heart Journal, found those who ate the most chocolate -- an average of 7.5 grams a day, about one-quarter of an ounce or one square or two of a chocolate bar -- had lower blood pressure and a 39 percent lower risk of having a heart attack or stroke compared to those who ate the least amount of chocolate.
"Small amounts of chocolate may help to prevent heart disease but only if it replaces other energy-dense food, such as snacks, in order to keep body weight stable," Buijsse said in a statement.

| CT scans: How much radiation is too much? WASHINGTON (UPI) -- The U.S. Food and Drug Administration began meetings on the risks of CT scans for colon cancer screening as scientists said the agency ignored their concerns.
The meetings, which continue Wednesday, came after The New York Times reported government scientists got nowhere when they raised concerns to the FDA about possible dangers of routine use of CT scans for colon cancer screenings.
The meetings represent a reassessment of risks associated with radiology at a time when average lifetime doses of diagnostic of radiation have soared.
About 70 million computed tomography scans are performed in the United States annually, up from 3 million in the early 1980s, and up to 14,000 people may die every year of radiation-induced cancers as a result, researchers say.
The Times cited FDA documents showing that after an agency official recommended approval of an application by General Electric to allow the use of CT scans for colon cancer screenings, Dr. Julian Nicholas, who was a gastroenterologist under contract with the FDA, said approving the application could "expose a number of Americans to a risk of radiation that is unwarranted and may lead to" abdominal cancer. The application is still under review.
FDA officials then told him to change his view, Nicholas said.
"I was first ignored, then pressured to change my scientific opinion, and when I refused to do that, I was intimidated and ultimately terminated," he said.
Experts differ on use of CT scans, particularly for healthy patients.
Alberto Gutierrez, deputy director of the FDA office that oversees radiological devices, said it's hard to say what's the best direction on CT scans for colon cancer.
Arvind Gopalratnam, a spokesman for GE Healthcare, wrote in an e-mail that research had shown that "CT colonography can be a very valuable, noninvasive screening tool to help diagnose colorectal cancer at early stages and ultimately improve overall survival rates."
A CT of a patient's abdomen is often used instead of a conventional colonoscopy, which is performed with a long, flexible tube with a camera inserted in a patient's colon.

| Inflammatory bowel disease up in China HONG KONG (UPI) -- A study of 79 children in China found an increasing diagnosis of inflammatory bowel disease in the recent decade compared with the 1980s and 1990s.
Study leader Dr. Tam YH of the Chinese University of Hong Kong reviewed a group of children who had their first colonoscopy within a six-year period.
The most common reasons for the procedure were blood in the stools and for the possibility of inflammatory bowel disease.
The study, published in the World Journal of Gastroenterology, found 23 children had colonic polyps and 13 had inflammatory bowel disease.
There were no complications by any of the study subjects, the study said.
It has recently been reported that there is increasing occurrence of childhood inflammatory bowel disease in Western countries.
Recently studies show an increase in childhood inflammatory bowel disease in Western countries, the researchers said.

| Canada: Minority women lack doctor access TORONTO (UPI) -- Immigrant women -- especially South Asian, West Asian or Arab women -- say they have trouble accessing healthcare in Canada, researchers found.
Researchers at St. Michael's Hospital and the Institute for Clinical and Evaluative Sciences found more than 50 percent of South Asian, West Asian or Arab adults say they were not very satisfied with their ability to get an appointment with a doctor for a regular checkup.
Nearly 40 percent of East and Southeast Asian and 34 percent of Aboriginal adults reported having difficulties when accessing a specialist compared with 22 percent of white Ontario residents.
The study also found that 15 percent of Canadian immigrants for less than five years do not have a primary care doctor, compared to 7.3 percent of Canadian-born men and women who say they don't have primary care doctor.
"Ensuring all Ontarians have equal access to care is important if we want to improve the health and well-being of men and women across the province," principal investigator Arlene Bierman, a physician at St. Michael's Hospital, said in a statement.
