Here's some sweet news about chocolate, just in time for Easter: A new study from Germany found that eating 7.5 grams of chocolate per day or just about one square from a bar could lower your risk of heart attack by 27 percent and lower your risk of stroke by 48 percent. It's believed this is due to the flavanol, an antioxidant, in cocoa:
But before you stock up on chocolate Easter eggs, researchers warn that the key to reaping the health benefits of chocolate is moderation. A single 100-gram bar of chocolate contains about 500 calories, and eating too much can contribute to unhealthy weight gain.
"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," researcher Brian Buijsse, a nutritional epidemiologist at the German Institute of Human Nutrition in Nuthetal, Germany, says in a news release.
If you think someone is too old to be acting like a teenager, you may be wrong. According to research from the U.K., psychologists say that adolescence may last as long as up to age 28 and start as early as age eight:
Adelaide-based adolescent psychologist Dr. Darryl Cross said parents were not prepared to deal with, or failed to recognize, "teenage-like behavior" outside what is normally considered adolescence, The Advertiser reported....
"It's related to earlier physical changes with the younger kids and social changes, such as staying at home longer with the older ones,” Cross said. "But despite this, parents just have not caught up to the fact that these changes are occurring and how to deal with them."
British scientists studying the genetics of ageing in worms have found a gene linked to lifespan and immunity. The information could lead to drugs and technology to help people live longer and healthier lives:
Since the gene, called DAF-16 in worms, is found in many animals and in humans, the finding could open up new ways to affect aging, immunity and resistance in humans, the scientists said.
"We wanted to find out how normal aging is being governed by genes and what effect these genes have on other traits, such as immunity," said Robin May of the University of Birmingham, who led the study.
