Poop bacteria in most public swimming pools
Much the way the movie Jaws had a lot of people thinking twice before going swimming in the ocean, a new Centers for Disease Control and Prevention report may make you reconsider a trip to the neighborhood swimming pool. According to the study, 58 percent of public pools in the U.S. had E. coli bacteria, an indicator of the presence of feces. Bacteria P. aeruginosa was also found in 59 percent of pool samples, which indicates contamination from the environment, swimmers or other objects that can transmit microorganisms.
The _E. coli_bacteria are typically found in the guts of warm-blooded organisms, including humans, and can be transferred to the pool if someone does not appropriately wash feces off his or her body before swimming or by actually using the pool as a bathroom. While the majority of E. coli are harmless to humans, some can make people dangerously ill. Symptoms of an infection can include abdominal pain, fatigue, diarrhea, vomiting, fever and nausea.
This report serves as a warning to swimmers themselves and especially the parents of young swimmers. It recommends always taking a shower before swimming if you (or a child) are suffering from diarrhea to ensure that it has been fully washed off your body. And of course, don’t poop in the pool.

Aging brain benefits from Mediterranean diet
Researchers from the University of Navarra in Spain have added the Mediterranean diet to the list of strategies for slowing the cognitive decline of aging brains. Already hailed for its benefits to heart health, the diet–rich in fruits, vegetables, nuts, seafood, pasta, olive oil and even a little red wine–can boost brain power for older people who may be at risk for vascular dementia, according to the new research.
The study, which involved 522 men and women, aged 55 to 80, was designed to compare the Mediterranean diet to a low-fat diet to gauge which was more effective in warding off heart disease. After concluding that the Mediterranean diet, supplemented with extra-virgin olive oil and mixed nuts, reduced risk of heart attack, stroke and cardiovascular death, the team of researchers took a look at the potential cognitive benefits.
The researchers randomly categorized the participants – one group ate a Mediterranean diet with added olive oil, one group ate the Mediterranean diet with added mixed nuts, and the third ate a low-fat diet. The participants were followed for an average of six and a half years, with follow-ups every three months. They underwent tests for memory, attention, language, orientation, spatial awareness, abstract thinking and other brain functions. The results indicated that brain function test scores were significantly higher for the two Mediterranean diet groups than for the low-fat diet group.
This study adds to the growing list of studies indicating that diet can play a significant role in sustaining the brain.

Childhood ADHD and obesity linked
ADHD among American children continue to rise, as do obesity rates among U.S. adults and now a study has linked the two According to new research from the Child Study Center at New York University Langone Medical Center, men diagnosed with ADHD as children were twice as likely to be obese as adults than men who were not diagnosed with the condition.
The study included 207 white men diagnosed with ADHD at an average age of eight years old. It followed the group for decades, re-evaluating the patients when they were at an average age of 41. These patients were “matched” with 178 men who were not diagnosed with ADHD, but who had similar race, age, residence and social class. The study found that men with childhood ADHD had a higher Body Mass Index (BMI) than those who did not have the condition–30.1 for those with ADHD versus 27.6 for non-patients. Men with ADHD had significantly higher prevalence of obesity --41.1 percent as opposed to 21.6 percent in those who did not have ADHD.
According to CDC reports, ADHD is the most common mental health condition among children – affecting around seven percent of children, with more boys diagnosed than girls. Researchers believe that the lack of impulse control and poor planning skills –common symptoms of ADHD – may be the definitive factors leading to higher BMI and obesity rates.
The study appears in the May 20 online edition of Pediatrics.
