July, 2009 | | Mediterranean Foods Promote Longevity | | The Mediterranean diet is well known for making people live longer, but new research reveals the individual components of the diet which promote longevity. Professor Dimitrios Trichopoulos at the Harvard School of Public Health surveyed over 23,000 participants on lifestyle and diet. Participants were interviewed over a period of 8.5 years. Researchers found key Mediterranean foods to promote health and a longer life are vegetables, fruits, nuts, pulses, and olive oil. Researchers recommend limiting the amount of meat you eat, and moderating alcohol intake. |  The study also shows that a diet high in fish, seafood, and cereals, and low in dairy does not necessarily indicate longevity.

June, 2009 | | Growing New Knees | | It's that painful pop or snap more than 80,000 Americans hear every year. ACL tears often mean surgery to repair cartilage and months of rehab, but even that doesn't always ease the pain. The answer for knee injuries may be growing in the lab. Lisa Groom takes on the San Francisco hills with confidence. But not long ago, a knee injury while playing tennis kicked her off the court. "I hit the shot and won the game, and I collapsed onto the ground," Groom told Ivanhoe. "I felt my tibia push out the side of my leg totally." She tore her ACL and destroyed her knee cartilage. The damage meant months of pain. "It can overtake you," Groom said. "I would be awake all night on and off feeling it." The tissue can't re-grow itself -- meaning treatment options are limited. "Cartilage cells are very lazy cells," Benjamin Ma, M.D., Chief of Sports Medicine and Shoulder Surgery at the University of California in San Francisco, Calif., told Ivanhoe. | Traditional procedures remove damaged cartilage but can't replace it. But Dr. Ma is helping develop new surgery that can replace it -- with a patch made of a patient's own cells. Surgeons remove a sample of the patient's knee cartilage through a 10- to 15-minute outpatient procedure. That cartilage is then sent to the lab, attached to a 3-D scaffold made of collagen, and grown for eight to 10 weeks. Then, the cartilage "patch" is implanted into the patient's knee. "You're actually putting articular cartilage back into the knee, and you're not taking it from somewhere else," Dr. Ma said. It's a more natural way of healing injuries that means patients can give their knees a new start. Following the Neocart procedure, patients have to keep off their leg for six weeks. The procedure doesn't work for arthritis. Dr. Ma says he plans to grow larger pieces of cartilage so doctors could potentially heal an entirely worn out knee.

May, 2009 | | 8 Foods to Die For | | We all know the drill; Avoid fats, carbs, and sugar if you want to stay healthy and slim. But what foods could be holding you back? Here are eight foods that could be hurting your health and waistline. Cheese fries top our list. An order from a popular restaurant has 2,900 calories, 182 grams of fat and hardly any nutritional value! Fried desserts are another worst. Donuts are made up of about 40 percent trans fat. Guidelines suggest we shouldn't have any trans fats. "You're dipping something in batter that is already high in calorie, high in fat, high sugar," Sarah Krieger, R.D., M.P.H., LD/N, a spokesperson for the American Dietetic Association in Tampa, Fla., told Ivanhoe. Soda is number three. One can has about 10 teaspoons of sugar, 150 calories and is loaded with artificial colors. A large serving of movie theatre popcorn with butter has more than 1,000 calories. One study showed you'll eat nearly twice as much out of a large bucket than a medium! It's no surprise that bacon cheeseburgers made our list. One can have more than 1,100 calories and 85 grams of fat. Crackers, breads and other "white" foods come in at number six. | "White flour, in the human body, is handled exactly like if you sat there and ate sugar out of the bowl," Ann Kulze, M.D., a nutrition and wellness expert in Charleston, SC, told Ivanhoe. Ramen noodles are number seven. One serving has 780 grams of sodium. "They are deep-fried noodles," Krieger said. "They do not have any protein in them." Last, but not least: that sugary coffee is one of the worst. "It can go from something that's zero calories to something that's over 700 calories very easily," Sherri Flynt, R.D., Community Relations Manager for Florida Hospital Center of Nutritional Excellence in Orlando, Fla., told Ivanhoe. Eight foods to avoid if you can! Some of the best foods to eat? Nutrition experts say load up on foods that are high in nutrients, protein and fiber. Some of the best include blueberries, oatmeal, salmon, almonds, low-fat yogurt and dark greens like spinach or kale. SOURCE: American Dietetic Association |

Fish Eating Frenzy
|
|
New research
shows recent recommendations to eat more fish may not be best
for us -- or for fish! Omega-3 fatty acids, found naturally in
fish like salmon, mackerel and herring, have been praised for
reducing the risk of coronary heart disease and some cancers.
This prompted health agencies and doctors alike to urge the
public to consume two- to three-times more fish to achieve these
health benefits. However, researchers say while some studies
have shown health benefits from omega-3 fatty acids,
insignificant attention has been paid to studies that do not
show these benefits, perhaps misleading the public into eating
too much fish.
Increased consumption of fish has also taken its toll on the
fish population. In fact, since the 1980s, more than 100 cases
of marine extinctions have been reported around the world.
|
Poorer countries are also suffering from America’s new love of fish; fisheries around the world are diverting their declining stocks to more affluent developed nations, causing serious consequences for those in poorer countries and costal communities.
These trends
imply the collapse of all commercially exploited stocks by
mid-century," the authors wrote. "Yet the dire status of
fisheries resources is largely unrecognized by the public, who
are both encouraged to eat more fish and are misled into
believing we live in a sea of plenty."

7 Sleep Myths |
|
You spend
one-third of your life sleeping. Not getting the right amount or
the right quality of rest can wreak havoc on your health, but
there are a lot of myths surrounding the crucial habit. Here are
seven misconceptions about sleep that may surprise you.
It's the way we rest, relax and recharge our bodies. How much
do you need? Myth number one -- more is always better.
"You'll find that they really need between seven and a half to
eight and a half hours [of sleep]," Robert Thornton, M.D., sleep
medicine specialist and co-medical director of the Florida
Hospital Center for Sleep Disorders in Orlando, Fla., told
Ivanhoe.
Too much sleep has been linked to diabetes and depression. Some
studies have found people who sleep more than nine hours a night
die younger -- but if you don't get enough, can you make up sleep?
While sleeping in one morning may seem to help, it often makes it
more difficult to fall asleep that night and each night after
that.
"If you're doing it on a chronic basis, it's going to catch up
with you," Dr. Thornton said.
|
What about naps? It's a myth that naps are no good, but don't
sleep longer than an hour, and don't nap after 3 p.m.
Myth number four -- snoring is normal. Chronic snoring can put
you at risk for heart disease, sleep apnea, high blood pressure
and diabetes. Another myth -- you need less sleep as you age.
"We need the same amount of sleep as we get older," Dr. Thornton
said. "We don't typically get quite as much deep sleep."
Myth number six -- waking up during the night means you didn't
sleep well.
"That depends on how long it takes you to get back to sleep,"
Dr. Thornton said.
You're OK if you fall back asleep within a few minutes. The
final myth -- insomnia is always caused by worry. While that's
true for some, persistent insomnia is often caused by depression,
asthma, arthritis or other medical conditions.

Turn off the TV to
Prevent Diabetes |
|
Looking for a
simple way to prevent diabetes? Turn off the TV and put on your
walking shoes.
Type 2 diabetes impacts 20.6 million Americans, and
African-American women make up a significant percentage of that
population. A new study suggests if those women would reduce the
time they spent watching television and increased the time they
spent walking briskly or engaging in another vigorous activity,
they could drastically reduce their risk of developing diabetes.
Researchers from Boston University's Slone Epidemiology Center
examined data collected in the Black Women's Health Study, an
ongoing study of African-American women from across the U.S. The
researchers found that vigorous activity was inversely associated
with a reduced risk of diabetes. Brisk walking for at least five
hours per week was also linked to a reduced risk of diabetes
compared with no walking at all.
|
The study also found a big reason to turn off the TV. Even in
those women who frequently watched TV but were still physically
active, they still were at an increased risk for developing type 2
diabetes.
Julie Palmer, a professor of epidemiology at BU's Slone
Epidemiology Center and the study's author, said her team's
results show that vigorous activity and brisk walking can protect
African-American women against type 2 diabetes.
"That is important because many women don't have the time or
place to engage in 'vigorous' physical activity, but most women
can find time to walk," she was quoted as saying.

Smokers Should Eat Broccoli |
|
Broccoli and other
cruciferous vegetables have a cancer preventative property that
appears to work specifically in smokers. In the first
comprehensive study of it’s kind, researchers at Roswell Park
Cancer Institute, in Buffalo, N.Y., analyzed cancer cases and
controls matched on smoking status. The study included all
commonly consumed cruciferous vegetables, taking into account
their raw versus cooked forms.
Among smokers, the protective effect of the vegetable intake
ranged from a 20 percent reduction in risk of lung cancer to a 55
percent reduction in risk.
|
“Broccoli is not a therapeutic drug, but for smokers who
believe they cannot quit nor do anything about their risk, this is
something positive,” Li Tang, Ph.D., the study’s lead author, was
quoted as saying.
Researchers noted the strongest risk reduction was seen in
patients with squamous and small-cell carcinomas, two subgroups
more strongly associated with heavy smoking.

Alcohol May Cause
Lower Brain Volume |
|
Studies show
moderate alcohol consumption is associated with lower risk of
cardiovascular disease, but a new study reveals it may also be
associated with brain volume decline.
It’s generally considered that older adults aren’t as sharp
mentally as younger adults. This may be because brain volume
decreases with age at a rate of about 2 percent per decade. Lower
brain volume is also found in patients with dementia and is
associated with thinking, learning and memory problems. Now,
researchers at Boston University School of Public Health have
found another possible cause of lower brain volume -- alcohol
consumption.
Researchers studied 1,839 adults and categorized them into
groups based on their reported weekly alcohol consumption. |
“My original
question was since alcohol is protective for cardiovascular
disease, is it protective when looking at the decline in brain
volume with age?” Carol Ann Paul, M.S., researcher at Boston
University School of Public Health, told Ivanhoe.
The results of the study showed that instead of protecting against
age-related brain volume decline, alcohol actually made it worse.
“With an increase in alcohol we found a decrease in brain volume,”
Paul said. “Unlike the cardiovascular system, there’s no protect
effect in the decline of brain volume.”
Paul added her next step in this research is to study the link
between alcohol consumption and cognition to paint a clearer
picture of the effects of alcohol on the brain.

Exercise Delays
Alzheimer's Symptoms |
|
It's recommended
for weight loss, stress relief and energy boosts -- and now,
exercise may also be used as a weapon in the fight against
Alzheimer's Disease (AD). A new study shows moderate exercise
may prevent the onset of AD by slowing memory decline, an early
symptom of the disease. Researchers randomly assigned older adults
at increased risk of dementia into either a 24-week exercise
program or an education program.
Participants in the exercise program were encouraged to
exercise three times a week for 50 minutes, with the most
frequently recommended activity being walking. Cognitive function
was evaluated over 18 months.
|
Exercise benefited the participants for at least 12 months
after intervention had ended.
Results show participants who exercised had better cognitive
function and dementia scores, and faster recall than those who
didn't.
Study authors wrote that the impact exercise had on memory is
especially important considering the participants only engaged in
moderate exercise.

Popcorn and Nuts
Good for Your Health |
|
It has been long
believed that eating nuts, corn and popcorn can aggravate and even
cause diverticulosis – a common digestive disorder. However,
results of a new study give reason to dismiss that claim. In a
large study of men from 1986 to 2004, researchers not only found
that nut, corn and popcorn ingestion was not associated with an
increase in diverticular disease or diverticular bleeding, but
rather found the opposite to be true.
Men with the highest intake of nuts (at least twice per week)
had a 20 percent lower risk of diverticulitis compared with men
with the lowest nut intake (less than once per month). |
Similarly, men
with the highest intake of popcorn had a 28 percent lower risk of
the disease compared with men with the lowest popcorn intake.
These findings refute the pervasive but unproven belief that these
foods are associated with diverticular complications and suggest
that the recommendation to avoid these foods in diverticular
disease should be reconsidered,” study authors write.

Veggies may Prevent
Blindness |
|
It turns out
following mom's advice to eat your vegetables could prevent a
leading cause of blindness. Age-related macular degeneration
causes vision loss in Americans 60 years of age and older. It
affects the macula -- the part of the eye that allows you to see
fine detail. Several studies have suggested high concentrations of
lutein and zeaxanthin -- dietary compounds -- have properties that
can prevent macular degeneration.
These nutrients are not made by the body and can only enter the
bloodstream through one's diet. |
They are commonly
found in green, leafy vegetables, like spinach, broccoli, zucchini
and kale, and in yellow or orange fruits and vegetables, like
carrots, papaya, squash and peaches.
Previous studies found lutein and zeaxanthin filter out damaging
blue light and are powerful antioxidants, which could explain why
they may protect against macular degeneration.

Coffee Could Lower Death
Risk |
|
Having that
morning cup of coffee every day could help protect you from heart
disease. New research finds drinking coffee regularly – up to six
cups a day – actually reduces your risk of dying from heart
disease.
The study analyzed data of 84,214 women who were in the Nurses’
Health Study and 41,736 men from the Health Professionals
Follow-up Study. Participants answered questionnaires every two to
four years about how frequently they drank coffee, other diet
habits, smoking and health conditions.
Researchers found women who had two to three cups of coffee per
day had a 25 percent lower risk of death from heart disease during
the follow-up period – from 1980 to 2004 – compared with those who
didn’t drink coffee, and an 18 percent lower risk of dying from
something other than cancer or heart disease. Men who drank the
same amount of coffee had neither a higher nor a lower risk of
death from 1986 to 2004.
|
Results also show there was no association between drinking
coffee and dying of cancer. This does not seem to be related to
caffeine because people who drank decaf also had lower death rates
than those who did not drink coffee.
The editors of Annals of Internal Medicine caution the design of
the study does not make it certain that coffee reduces the chances
of dying sooner than expected. They say something else about
coffee drinkers might be protecting them. There might also be some
errors in how much coffee participants drank because the estimated
consumption came from self-reports.

Cup of Cocoa Good
for Diabetic Health |
|
Sipping a hot cut
of cocoa might do more than just warm you up if you have diabetes.
It could also be helping improve your blood vessel functioning.
German researchers have found a key ingredient in cocoa called
flavanols makes it easier for the arteries to expand in the face
of increased demand for blood. Since people with diabetes
generally have problems with artery expansion, anything that helps
open up the flow could reduce their risk for cardiovascular
complications.
The study involved 41 type 2 diabetics who were randomly
assigned to drink specially formulated cocoa with either high or
low concentrations of flavonols over a 30-day period. All the
participants underwent regular tests to measure blood flow in the
arteries. While the initial tests showed diabetics had
significantly lower expansion of arterial diameter in the face of
increased demand for blood, results improved significantly
following the consumption of high flavonol cocoa, and by the end
of the study, were at normal levels.
|
The researchers are quick to note that the cocoa used in the
study is not available in stores, so people shouldn’t rush out and
begin drinking hot chocolate to achieve the same results. The take
home message is flavonols – which are also found in tea, red wine,
and some fruits and vegetables – may have a role to play in
promoting heart health in people with diabetes.
“This study is not about chocolate, and it’s not about urging
those with diabetes to eat more chocolate. This research focuses
on what’s at the true heart of the discussion on ‘healthy
chocolate’—it’s about cocoa flavanols, the naturally occurring
compounds in cocoa,” study author Malte Kelm, M.D., was quoted as
saying. “While more research is needed, our results demonstrate
that dietary flavanols might have an important impact as part of a
healthy diet in the prevention of cardiovascular complications in
diabetic patients.”

Alzheimer’s:
Vitamin for Longer Life |
|
Taking high doses
of vitamin E appears to extend the life of people with Alzheimer’s
disease. The findings are the result of a study authored by
Valory Pavlik, Ph.D. of Baylor College of Medicine’s Alzheimer’s
Disease and Memory Disorders Center in Houston, Texas.
After receiving 1,000 international units of vitamin E twice a
day for five years, the patients were 26 percent less likely to
die than those who did not take the vitamin. Whether they were
also taking an Alzheimer’s drug (cholinesterase inhibitor) did not
make a difference. Dr. Pavlik notes the dosage was much higher
than what is currently recommended for the general public.
Previous studies showed vitamin E can delay the progression of
moderately severe Alzheimer’s disease. |
“Now, we’ve been able to
show that vitamin E appears to increase the survival time of
Alzheimer’s patients as well,” Dr. Pavlik was quoted as saying.
“This is particularly important because recent studies in heart
disease patients have questioned whether vitamin E is beneficial
for survival.”
According to the study, patients who took vitamin E plus an
Alzheimer’s drug appear to get a greater benefit than those taking
either one alone. However, people who took the drug but not
vitamin E did not have any survival benefit. Dr. Pavlik says more
research is needed to find out why.

Take a Snooze, Boost
Your Memory
|
|
A catnap during
the day can boost our ability to remember specific tasks learned
beforehand -- but only if we’ve learned them well.
Researchers from Harvard Medical School found a 45-minute
snooze following a memory task training session only benefited
people who mastered the tasks.
The study involved 11 men and 22 women with an average age of
about 23 who arrived at the sleep lab at 11:30 in the morning,
went through the training at 12:15 p.m., and then were randomly
assigned to take a 45-minute nap at 1 p.m. or stay awake. At 4
p.m., all the participants were retested on the memory tasks.
“These results suggest that there is a threshold acquisition
level that has to be obtained for sleep to optimally process the
memory,” study author Matthew A. Tucker, Ph.D., was quoted as
saying.
|
“The importance of this finding is that sleep may not
indiscriminately process all information we acquire during
wakefulness, only the information we learn well.”
Still, getting a good night’s sleep is important for everyone.
The following do’s and don’ts come from the American Academy of
Sleep Medicine:
· Do establish a consistent bedtime routine.
· Do make bedtime relaxing.
· Do plan to get a full night’s sleep every night.
· Do keep your bedroom quiet, dark, and cool.
· Do get up at the same time every morning.
· Don’t consume caffeine or medicines containing stimulants
prior to bedtime.
· Don’t take your worries to bed.
· Don’t go to bed hungry, but don’t eat a big meal right before
bedtime either.
· Don’t engage in rigorous exercise within six hours of bedtime.

Hit the Weights to Lose
Weight |
|
Trying to lose
weight? A new study says instead of spending all of your time at
the gym doing cardiovascular exercise, you need to start weight
lifting. The study found weight training helps improve and control
your metabolism.
Researchers from Boston University School of Medicine conducted
the research in mice. They found the mice with more muscles lost
fat and showed other signs of metabolic improvement throughout the
body. The benefits were seen even though the mice were on a high
fat and sugar diet and didn’t increase any other physical
activity.
Researchers say type II muscle is what allows you to pick up
heavy objects and it may also be key in weight loss. |
Researchers write,
“These findings indicate that type II muscle has a previously
unappreciated role in regulating whole-body metabolism through its
ability to alter the metabolic properties of remote tissues.
These data also suggest that strength training, in addition to the
widely prescribed therapy of endurance training, may be of
particular benefit to overweight individuals.”
Study authors conclude increasing muscle mass in humans may
prove to be critical in the fight against obesity, diabetes, heart
disease, stroke, hypertension and cancer.
