Exercise: Lose Weight, Boost Brain

According to a new study, exercise helps overweight kids learn. Lose weight and get smarter—one heck of a bargain! Robert Preidt of HealthDay News reports:
Three months of daily, vigorous exercise can improve overweight kids' thinking, U.S. researchers report.


Physical activity can also lower their diabetes risk, reduce their body fat, and strengthen their bones, says a team that looked at about 200 overweight, inactive children, ages 7 to 11.

All the children learned about healthy nutrition and the benefits of physical activity. In addition, a third of the children exercised 20 minutes a day, and another third exercised for 40 minutes. During the exercise sessions, the children played running games and used hula hoops and jump ropes to get their heart rates to 79 percent of maximum -- considered a vigorous workout.
When I was a kid I used to run around all day, but I was still a little dummy!

Dieting or Exercising?

Well, this is an odd report. Judy Foreman of The Boston Globe asks the question, “Is dieting or exercise better for weight loss?” Let’s find out:
In a small, randomized, controlled clinical trial, Ravussin divided three dozen overweight but healthy men and women into three groups. One group reduced their calorie intake by 25 percent. Another group cut calories by half as much (12.5 percent) while increasing energy output through exercise by 12.5 percent; and the third group made no diet or exercise changes.


The researchers looked at weight loss, body composition, and measures of superficial and deep fat. They found that it doesn't matter whether people lose weight by diet or by exercise or a combination, although exercise has the important benefit of improving cardiovascular health.

"So long as the energy deficit is the same, body weight, fat mass, and abdominal fat will all decrease the same way," said Ravussin, in an e-mail.

Health Points: Tuesday

J&B Meats Corp. is recalling 173,554 pounds (78.7 tonnes) of frozen ground beef products sold under "Topps" and "Sam's Choice" labels due to possible E. coli contamination, the U.S. government said this weekend.

The Coal Valley, Illinois-based company produced the patties in June and distributed them to retail stores nationwide, the U.S. Agriculture Department's Food Safety and Inspection Service, or FSIS, said in a statement.
Scientists reported progress yesterday toward one of medicine’s long-sought goals: the development of a blood test that can accurately diagnose Alzheimer’s disease, and even do so years before truly debilitating memory loss.


A team of scientists, based mainly at Stanford University, developed a test that was about 90 percent accurate in distinguishing the blood of people with Alzheimer’s from the blood of those without the disease. The test was about 80 percent accurate in predicting which patients with mild memory loss would go on to develop Alzheimer’s disease two to six years later.
A diverse group of low-income women participated in the study, Dr. Alyson B. Moadel of the Albert Einstein College of Medicine in the Bronx, New York, noted in an interview with Reuters Health. "Our patients really enjoyed the yoga classes, it was very well received by them," she said. "It really fit in with their own cultural interests."


There is mounting evidence that yoga can improve quality of life in both healthy and chronically ill people, Moadel and her team point out in the Journal of Clinical Oncology, while quality of life may be particularly affected for cancer survivors who belong to ethnic minorities and other underserved minority populations.
The ban on phthalate makes California the first U.S. state to impose severe limits on a chemical that is widely used in baby bottles, soft baby books, teething rings, plastic bath ducks and other toys, said Assemblywoman Fiona Ma, the bill's author.


"I think parents will be comforted that when they buy one of these chewy products it will be safe," Ma told The Associated Press on Sunday after the bill was signed into law.
New suspected cases of foot and mouth disease in sheep have been reported in Britain, the environment ministry said on Monday, in another county from the confirmed cases in this year's outbreak.


A three-kilometre (1.8-mile) temporary control zone has been imposed around premises close to the town of Rye, near the southern English coast, after sheep showed possible symptoms of the disease. Tests were being carried out.
Good news for us early birds who grit their teeth to get through the afternoon because our evolutionary bio-rhythms are at their lowest ebb.


Research by Liverpool’s John Moores University has shown that the mere thought of an afternoon siesta can help reduce the risk of a heart attack. The length of the nap is irrelevant as it is in the minutes just before we drop off when the beneficial changes to our body take place.
President Hu Jintao said Monday China would step up efforts to improve food safety and prevent the spread of animal diseases, in a speech opening the Communist Party's five-yearly Congress.


"We will intensify efforts to prevent animal and plant epidemic diseases and improve the quality and safety of agricultural products," Hu said.

Later in the speech, he said: "We must ensure food and drug safety."
A turning point came in 2002, scientists conclude Monday in the annual "Report to the Nation" on cancer. Between 2002 and 2004, death rates dropped by an average of 2.1 percent a year.


That may not sound like much, but between 1993 and 2001, deaths rates dropped on average 1.1 percent a year.

The big change was a two-pronged gain against colorectal cancer.

Asthma: Pound the Rock

A Pittsburgh basketball camp is doing its part to help kids with asthma. Jill Daly of The Pittsburgh Post-Gazette reports:
It's easy to understand why the children don't participate in sports, said Dr. David Skoner, asthma specialist at Allegheny General Hospital's Division of Asthma, Allergy and Immunology.


"Exercise triggers [asthma] symptoms in 90 percent" of children with asthma, he said. Sometimes parents don't even know why it is their child is not interested in sports, he said.

"We've got to find a way to get these kids exercising," he said. "Not exercising leads to rising obesity and makes asthma worse."

The two camps are recruiting children from throughout the region. Both combine asthma education and basketball skills.

The new camp is a partnership between AGH and the university's DiSepio Institute for Rural Health and Wellness. Other community health organizations are involved as well. Basketball skills are taught by the university's head basketball coach, Bobby Jones, and his players.

Exercise: Yoga True and False

I’ve been doing Yoga for a few months now and I can tell you firsthand—it’s an amazing work out! If you’re curious about it, Health answers a few questions about Yoga. Check it out:
Claim: Yoga can help you lose weight. | TRUE
How much depends on the type, how often you do it, and your diet (of course). More-athletic styles—most notably ashtanga, a.k.a. power yoga—burn more calories and help build more muscle (which translates into an even higher number of calories torched) than more-meditative versions. A 150-pound woman can work off more than 460 calories during a single hour of power yoga (versus around 170 calories for a traditional yoga session). Many celebrities, including Serena Williams, love how yoga helps them stay in shape.


Claim: Yoga cures asthma. | FALSE
Many asthma patients believe doing certain types of breathing techniques can help reduce their symptoms. But research published in the medical journal Thorax suggests that yogic breathing isn’t one of them: Participants who used a device that mimicked the breathing technique pranayama saw no improvement in their asthma symptoms.

Alzheimer's This and That

Okay busy bees, this should make you feel a lot better about yourselves. A new study claims organized driven people have a lower risk of developing Alzheimer’s disease. Carla K. Johnson of the Associated Press has more:
A purposeful personality may somehow protect the brain, perhaps by increasing neural connections that can act as a reserve against mental decline, said study co-author Robert Wilson of Chicago's Rush University Medical Center.


Astoundingly, the brains of some of the dutiful people in the study were examined after their deaths and were found to have lesions that would meet accepted criteria for Alzheimer's -- even though these people had shown no signs of dementia.

"This adds to our knowledge that lifestyle, personality, how we think, feel and behave are very importantly tied up with risk for this terrible illness," Wilson said. "It may suggest new ideas for trying to delay the onset of this illness."

Previous studies have linked social connections and stimulating activities like working puzzles with a lower risk of Alzheimer's. The same researchers reported previously that people who experience more distress and worry about their lives are at a higher risk.
Couple this with last year’s report showing that exercise helps stop Alzheimer’s and task masters everywhere can rejoice! Now, if you also eat healthfully, you’re in really good shape because Dr. Fuhrman links superior nutrition to Alzheimer’s prevention. Here’s a quote:
Alzheimer’s dementia is an irreversible brain disorder that typically develops in the elderly. It leads to memory loss, personality changes, and a general decline in cognitive function.


With the high incidence of Alzheimer’s disease in our aging population, more and more research is underway to come up with novel treatments for this brain disease. Given the large distortion of brain architecture that occurs in Alzheimer’s, it is unlikely that drug treatment will offer a solution to this debilitating problem.

Green vegetable consumption was low and animal fat consumption was high in the past histories of Alzheimer’s patients.1,2 Japanese studies have found the same relationships: individuals with low consumption of vegetables and high consumption of meat were found to be the ones most likely to develop Alzheimer’s.3

Just as in the case of heart disease, the world’s leading researchers on the subject consider diets high in animal fat to be the major factor in the causation of Alzheimer’s. Oxidative stress to our brain tissue from the combination of a diet rich in saturated fat and low in the antioxidants and phytochemicals found in fruits and vegetables lays the groundwork for brain damage later in life. Deficiencies of DHA (a long-chain omega-3 fatty acid) which often are found in Alzheimer’s patients, also have been shown to promote dementia.4 Inadequate intake of omega-3 fatty acids found in flax and hemp seeds, walnuts, leafy greens,and certain fish also are implicated in the etiology of Alzheimer’s.
All this certainly gives you a fighting chance against this often mysterious disease. For more on Alzheimer’s, check out DiseaseProof’s Alzheimer’s category.
