Exercise Lowers the Genetic Risk for Obesity

Wednesday, September 1st, 2010

The World Health Organization estimates 1 billion adults are overweight and at least 300 million are clinically obese. Health officials blame the increased consumption of nutrient-poor, energy dense foods – such as sugar, saturated fat, and fast food – and reduced physical activity for the spike in obesity.

Obesity is a known risk factor for various diseases, including cardiovascular disease, type-2 diabetes, sleep apnea, and certain types of cancer.

And while poor diet and inactivity is commonly blamed for obesity, mental illness, like eating disorders and depression, and genetics may increase a person’s risk of becoming overweight or obese.

But as for genetics, in a new study, published in the Public Library of American Science Medicine journal, researchers say exercise can reduce individuals’ genetic predisposition to obesity.

The study involved 20,430 people living in Norwich, Britain and found most participants inherited to 10 and 13 genetic variants known to raise the risk of obesity; some people inherited as many as 17 variants.

Data showed each genetic variant was associated with grams of weight. In active individuals the genetic variant increase was equivalent to a 592 gram increase in body mass index, but people who exercise only had a 379 gram increase.

So the researchers reiterate that in order to help prevent obesity it is important to get plenty of exercise.

Cashew Seed Extract May Help Diabetics

Thursday, August 5th, 2010

Cashew nuts have traveled the globe; native to Brazil but transplanted to India by the Portuguese in the 1560s and eventually imported from India to the United States in 1905.

And cashews, like a lot of nuts, are seen as high-nutrient foods. Cashews are a good source of dietary fiber, protein, iron, potassium, zinc, and polyunsaturated fat, which helps protect against cardiovascular disease.

Plus cashews might help against diabetes too. A new study says an extract from the cashew seed may anti-diabetic properties.

Published in the journal Molecular Nutrition & Food Research scientists conducted in-vitro testing on mouse and rat liver cells, and found cashew seed extract helped boost glucose.

Cashew seed extract contains anacardic acid which stimulates glucose uptake.

Scientists also tried extract from cashew plant leaves, bark, and apples, but these materials did not have an effect on the uptake of glucose.

While it’s too premature to say conclusively, the researchers suggest cashew seed extract could be used as an anti-diabetic nutraceutical.

Weight Gain Later in Life Heightens Diabetes Risk

Thursday, June 24th, 2010

Fat around the waist – often referred to visceral or abdominal fat – is probably the worst kind of fat you can have.

Visceral fat concentrates around the abdominal cavity, in between the internal organs, and has been linked to both obesity and cardiovascular disease.

Like most extra body fat, visceral fat has also been shown to increase diabetes risk. And now a new study found packing on the belly fat later in life is especially bad for developing type-2 diabetes.

Published in the Journal of the American Medical Association, scientists determined people gaining abdominal fat over the age of 50 have nearly triple the risk of developing type-2 diabetes.

For the study, body-mass index (BMI), waist circumference, and waist-to-hip ratio were collected from 4,200 participants older than 65. And while none of the individuals had diabetes at the start of the study, people with the highest beginning measurements had a 4.3 times higher risk of type-2 diabetes, compared to participants with the lowest measurements.

Waist circumference was also a major factor for developing type-2 diabetes. Men with waist measurements above 104.6 centimeters had a 5.1 times higher risk and women with a waist circumference of 101.1 increased their risk by 3.6 times.

High BMI raised diabetes risk too; 5.6 times for men and 3.7 times for women.

Researchers urge people to be mindful of their weight at all times, but especially as you approach midlife. In the United States, as much as 95% of the diabetic population suffers from type-2 diabetes. Type-2 diabetes is brought on by poor diet and lack of exercise.

Brown Rice is Better at Cutting Diabetes Risk

Thursday, June 17th, 2010

Take a bag of sugar and pour the sugar down your throat. That’s pretty much the same thing as eating oodles of white rice.

White rice is white because it’s milled and processed, robbing it of any nutritional value and transforming it into “empty” carbohydrates.

And many food producers, after the milling process, actually re-enrich the rice by putting nutrients back in.

Brown rice is different. It isn’t milled or only minimally, leaving its nutrients intact.

So its no surprise that a new study found brown rice – i.e. the healthier rice – is better for reducing the risk of developing diabetes.

Published in the Archives of Internal Medicine, data shows if you eat over 12 ounces of white rice per week, switching to brown rice will lower your risk of type-2 diabetes by 16%. And if you replace all of your white rice with any sort of whole grain, your diabetes risk could be cut by an additional 36%.

White rice ranks high on the glycemic index – just like sugar – and diabetes makes it difficult for the body to process blood sugar into energy, so consuming white rice presents the same problem as eating sugar.

Brown rice is a better choice because it is less processed and retains its nutrients and hearty husk, which is an insoluble fiber.

Other whole grains include bran, oatmeal, and barley.

Diabetes and Sugar Linked to Mental Illness

Tuesday, June 15th, 2010

Sugar is hard not to like. It’s in chocolate, ice cream, candy bars, soda, doughnuts, etc. And Western diet styles – which most of the world eats nowadays – are loaded with sugar.

Not only will sugar make you fat, but sugar also raises your risk of diabetes, and that diabetes may raise your risk of mental illness, specifically depression and schizophrenia.

Writing in the journal PLoS Biology, researchers found mice engineered with an insulin-processing defect – mimicking that of diabetes – developed behavioral anomalies similar to patients with schizophrenia.

The mice also had reduced levels of dopamine. Dopamine is a “happy chemical,” like serotonin, and decreased levels of dopamine and serotonin are linked to depression.

Previous studies have shown diabetes and the inability of the body to handle sugar increased the risk of depression by lowering the brains supply of dopamine.

Researchers say within the diabetic population, 25% of people are depressed, compared to only 10% in non-diabetic individuals.

Alcoholism has also been shown to significantly raise the risk of depression, due to alcohol’s effect on lowering serotonin in the brain.

In 2000, the Mayo Clinic published a study claiming the suicide rate among depressed individuals is 2% to 9%.

18% of Americans are Sleep Deprived

Tuesday, June 8th, 2010

The rat race will run you ragged; wake up, get the kids ready, put them on the bus, drive to work, work, drive back from work, feed the kids, clean up, do laundry, pay bills, etc, etc.

And hopefully after that you have a few hours to get some sleep before starting it all over again – turns out a lot of people don’t.

Published in the journal Neurology, scientists found 18% of Americans don’t get enough sleep and sometimes doze off in the middle of the day, like during business meetings and conversations – or worse.

“The number of individuals sleepy or drowsy during situations where they should be alert is disturbing,” says Dr. Maurice Ohayon, professor of psychiatry at Stanford University and lead investigator of the new study, “Sleepiness is underestimated in its daily life consequences for the general population, for the shift workers and for the people reducing their amount of sleep for any kind of good reasons. It is always a mistake to curtail your sleep.”

Now you know why they put all those divots on the shoulder of major highways, to keep us from blacking out and jumping the gorge.

Insufficient sleep has been linked to weight gain, increased risk of diabetes, headaches, and memory loss.

Lack of Sleep Raises Insulin Resistance

Wednesday, May 5th, 2010

Maybe you can go a day on not enough sleep, but anything more and you’re the walking dead – miserable and irritable.

But it turns out just one measly day of too little sleep throws your body out of whack.

In a new study, published in Journal of Clinical Endocrinology & Metabolism, researchers say a single night of partial sleep deprivation may induce insulin resistance – even in healthy people.

A symptom of type-2 diabetes is insulin resistance – the body’s inability to properly use it – and scientists discovered not getting sufficient sleep increases this risk.

Other studies have also shown lack of sleep to be a risk factor for type-2 diabetes, along with poor diet in sufficient exercise.

Too bad in today’s fast-paced, sink or swim world sleep is often cut short.

A Little Bit of Booze Reduces Diabetes Risk

Monday, May 3rd, 2010

Alcohol’s best use is making a fool out of yourself. But it has some health effects too.

We’ve all heard wine is good for your heart. And it could be good for diabetes too.

Published in the American Journal of Clinical Nutrition, a new study found one or two drinks a day may lower the risk of type-2 diabetes – but only a little.

Among healthy men and women – those eating right, exercising, and don’t smoke – moderate drinkers were 44% less likely to develop type-2 diabetes.

Even people just having a healthy bodyweight or regularly exercise who drank a little booze had a lower risk; with 65% and 35% respectively.

But the researchers warn this is no reason to take up drinking – ugh, no fun!

Taking Naps May Raise Diabetes Risk

Tuesday, March 2nd, 2010

NAPA midday snooze on the couch sounds like a good idea – feels like one too – but making a habit out napping could be harmful.

Writing in the journal Sleep, researchers say individuals who nap four to six days out of the week are more likely to have diabetes.

The study involved 20,000 Chinese adults, ages 50 and older.

When accounting for other factors – such as exercise, age, and diagnoses of hypertension or cardiovascular disease – frequent naps were still linked to higher diabetes risk.

For both men and women, taking naps four to six days per week increased their risk of diabetes by 36%; napping appears to impair fasting glucose levels.

Unless you work a demanding job with crazy hours, you should probably stop napping after kindergarten anyway.

Family History of Diabetes Doubles Women’s Risk

Monday, February 8th, 2010

DIYou can’t escape your genes. No matter how healthy you are, your family history is always a factor. Thanks mom and dad! Ugh.

That even includes things like diabetes risk.

A new study published in the journal Diabetes Care found that women with diabetes in their family have double the risk of developing the disease.

Researchers examined data on 73,227 women spanning a 20 year period, where 5,101 developed type-2 diabetes.

Findings showed women with at least one parent or sibling with diabetes had more than two-fold the risk of type-2 diabetes.
