Can diet affect your Alzheimer's risk? New research proves NUTRITION STRONGEST FACTOR in disease

Can diet affect your Alzheimer's risk?

December 31, 2011|By Deborah Kotz

Does eating a lot of fish and few processed foods really help protect against Alzheimer's disease? A new study indicates that nutrition could play nearly as strong a role as other factors like age, number of years of education, and high blood pressure.

In the study published online in the journal Neurology, researchers measured the level of nutrients in the blood of nearly 300 seniors and found that those who had high levels of vitamin D and omega 3 fatty acids -- both found in salmon, tuna, and other fatty fish -- as well as vitamins C, E, and B -- antioxidants found in fruits, nuts, and green leafy vegetables -- appeared to have somewhat more protection against early symptoms of Alzheimer's. They were less likely to have cognitive difficulties, memory problems, and brain shrinkage -- an indicator of Alzheimer's -- than those who had low levels of these nutrients.

Physical Exercise Strongly Linked to Improved Academic Performance

Physical Activity May Help Kids' Grades, Too

While physical activity is known to improve children's physical fitness and lower their risk of obesity, new research suggests it may also help them perform better in school.

Dutch researchers reviewed 14 previous studies from different parts of the world that looked at the relationship between physical activity and academic performance. Their review is published in the journal Archives of Pediatrics and Adolescent Medicine.

The data from the studies "suggests there is a significant positive relationship between physical activity and academic performance," wrote the authors, led by Amika Singh of the Vrije Universiteit University Medical Center's EMGO Institute for Health and Care Research in Amsterdam.

While they didn't examine the reasons why the relationship may exist, the authors, citing previous research, said regular physical activity seems to be linked to better brain function. The effect on the brain could be the results of a number of factors, including increased flow of blood and oxygen to the brain as well as higher levels of chemicals that help improve mood.

This latest report comes at a time when schools across the country debate cutting physical education from their curriculum or have already eliminated it because of budget constraints, the desire to stress academics or a combination of both. There is also concern that physical activity in schools can be detrimental to academic performance.

But in addition to the latest research review, a 2010 literature review done by the Centers for Disease Control and Prevention found that out of 50 studies, more than half showed a positive association between school-based physical activity -- such as physical education, recess and extracurricular sports -- and academic performance and about half found no effect. Only a few showed a negative relationship that could be attributable to chance.

Some of the research reported that concentration, memory, self-esteem and verbal skills were among the improvements noted in students who participated in school-based physical activity.

"School boards, school administrators and principals can feel confident that maintaining or increasing time dedicated for physical activity during the school day will not have a negative impact on academic performance, and it may positively impact students' academic performance," the CDC's authors wrote.

One of the reasons the Dutch authors decided to conduct their research review was concern over schools' emphasis on test scores.

"There is a focus on test scores and academic accomplishments, and there's a belief that schools need to cram all available time into academics," said Dr. David Geier, director of sports medicine at the Medical University of South Carolina in Charleston.

Geier was not involved in the Dutch research.

"The other problem," Geier said, "is that it becomes a funding issue for many schools."

If intellectual activities are incorporated with physical activities, Geier said, children will benefit both ways.

Geier's colleagues at the Medical University of South Carolina and a group of educators recently tried that combination at an elementary school. They incorporated 40 minutes of physical education every day that included a learning component for different grade levels. As an example, young children rode scooters while tracing shapes at the same time.

When the students took their spring standardized tests, more children achieved their score goal after the new physical education program than before it was implemented.

But even if there are no academic gains, physical activity in schools is still very important.

"There are cardiovascular benefits as well as decreased obesity and a decline in juvenile diabetes," said Geier.

"There's an even greater need for physical education now, because the vast majority of children's leisure activities are sedentary and involve technology," said Keith Ayoob, associate professor of pediatrics at the Albert Einstein College of Medicine in the Bronx, N.Y. "The problem is our bodies were not designed with technology in mind. They were designed for physical activity, and both children and adults should use this ability or we risk losing it."

While they reported an overall positive association between activity and academics, the Dutch authors stressed their conclusion was "cautious" because very few studies they analyzed were scientifically strong.

"Only 2 of 14 studies were rated as being of high methodological quality, which is the minimum number of studies needed for 'strong evidence,'" they wrote.

The studies also measured physical activity and academic achievement differently, and physical activity information often relied on self-reporting, which can be unreliable.

Because of the limitations of the prior research, the authors said more "high-quality" research is needed to accurately measure the relationship between physical activity and school performance.

"To gain insight into the dose-response relationship between physical activity and academic performance, we need more high-quality studies using objective measures of physical activity," they wrote.

For Neck Pain, Chiropractic and Exercise Are Better Than Drugs

For Neck Pain, Chiropractic and Exercise Are Better Than Drugs

Tony Cenicola/The New York TimesWhat's the best treatment for neck pain?
Seeing a chiropractor or engaging in light exercise relieves neck pain more effectively than relying on pain medication, new research shows.
The new study is one of the few head-to-head comparisons of various treatments for neck pain, a problem that affects three quarters of Americans at some point in their lives but has no proven, first-line treatment. While many people seek out spinal manipulation by chiropractors, the evidence supporting its usefulness has been limited at best.
But the new research, published in The Annals of Internal Medicine, found that chiropractic care or simple exercises done at home were better at reducing pain than taking medications like aspirin, ibuprofen or narcotics.
"These changes were diminished over time, but they were still present," said Dr. Gert Bronfort, an author of the study and research professor at Northwestern Health Sciences University in Minnesota. "Even a year later, there were differences between the spinal manipulation and medication groups."
Moderate and acute neck pain is one of the most frequent reasons for trips to primary care doctors, prompting millions of visits every year. For patients, it can be a difficult problem to navigate. In some cases the pain and stiffness crop up without explanation, and treatment options are varied. Physical therapy, pain medication and spinal manipulation are popular options, but Dr. Bronfort was inspired to carry out an analysis because so little research exists.
"There was a void in the scientific literature in terms of what the most helpful treatments are," he said.
To find out, Dr. Bronfort and his colleagues recruited a large group of adults with neck pain that had no known specific cause. The subjects, 272 in all, were mostly recruited from a large HMO and through advertisements. The researchers then split them into three groups and followed them for about three months.
One group was assigned to visit a chiropractor for roughly 20-minute sessions throughout the course of the study, making an average of 15 visits. A second group was assigned to take common pain relievers like acetaminophen and — in some cases, at the discretion of a doctor — stronger drugs like narcotics and muscle relaxants. The third group met on two occasions with physical therapists who gave them instructions on simple, gentle exercises for the neck that they could do at home. They were encouraged to do 5 to 10 repetitions of each exercise up to eight times a day. (A demonstration of the exercises can be found at www.annals.org).
After 12 weeks, the people in the non-medication groups did significantly better than those taking the drugs. About 57 percent of those who met with chiropractors and 48 percent who did the exercises reported at least a 75 percent reduction in pain, compared to 33 percent of the people in the medication group.
A year later, when the researchers checked back in, 53 percent of the subjects who had received spinal manipulation still reported at least a 75 percent reduction in pain, similar to the exercise group. That compared to just a 38 percent pain reduction among those who had been taking medication.
Dr. Bronfort said it was a "big surprise" to see that the home exercises were about as effective as the chiropractic sessions. "We hadn't expected that they would be that close," he said. "But I guess that's good news for patients."
In addition to their limited pain relief, the medications had at least one other downside: people kept taking them. "The people in the medication group kept on using a higher amount of medication more frequently throughout the follow-up period, up to a year later," Dr. Bronfort said. "If you're taking medication over a long time, then we're running into more systemic side effects like gastrointestinal problems."
He also expressed concern that those on medications were not as empowered or active in their own care as those in the other groups. "We think it's important that patients are enabled to deal with as much control over their own condition as possible," he said. "This study shows that they can play a large role in their own care."
