health briefs Eat Vegan Without
Compromising Stamina For runners, food is fuel, and a new study lays to rest debates about which diet is best. Researchers at Leibniz University, in Hannover, Germany, recruited 76 men and women runners, divided equally between vegans, vegetarians and omnivores. They had an average age of 27 and ran recreationally two to five times a week. The runners were asked to pedal to exhaustion on a stationary bike, and researchers found that all three groups had similar exercise capacity and power output, and similar lactate production during exercise. The researchers con- cluded that vegan diets were “a suitable alternative for ambitious recreational runners.”
Be a ‘Warm’ Parent to Extend Kids’ Lives
Cold or
unsupportive mothering styles can harm a child’s health into adulthood, Loma Linda University re- searchers have found. Compared to adults mothered in a “warm” style, adults that had been mothered in a “cold”
manner had an average of 25 percent shorter telomeres, indicating faster cellular aging, a shorter life span and greater susceptibility to disease. The study was based on follow-up blood samples of 200 adults originally enrolled in cohort studies of 130,000 people starting in 1976. Those that described their moth- ering as cold tended to be overweight or obese as adults, with less education. A father’s parenting style had a much smaller effect and was not significant enough to impact telomere length, the authors found.

Sleep Tight to Keep Ulcers at Bay
About one in 10 Americans develops painful peptic ulcers, open sores in the lining of the stomach and duodenum, that are sometimes caused by an overgrowth of the Helicobacter pylori bacteria. Drug therapy to eradicate the bacteria involving two antibiotics and one acid suppressant is usually successful, but about 10 percent of cases recur.
A key factor may be sleep quality, sug- gests a new study from the University of Hong Kong. Researchers followed 1,420 people that had been treated for peptic ulcers for three years. The ulcers recurred in 8.3 percent of them, and those that had poor sleep—including taking longer to fall asleep and waking more during the night—were significantly more likely to be re-infected. Longer total sleep times helped reduce infection recurrence.
Soak Up Rays for
a Healthier Bowel Regular exposure to sunlight decreases the incidence of irritable bowel disease (IBD) in children, researchers from the Australian National University report. They compared 99 children with IBD with 396 healthy children using interviews with parents to establish a database. For
every 10 minutes of sunlight exposure a day on aver- age, there was a 6 percent reduction in risk, and 30 minutes a day reduced the risk by 20 percent. Also, children with deeper tans were at lower risk. IBD, which includes Crohn’s disease and ulcerative colitis, has been shown in previous studies to be less common among people that live in sunnier places and closer to the Equator.
