insulin spike chartGlycemicEdge.com, a leading nutrition and health wellness community site, has updated and expanded its popular glycemic index food list and now features food scores from 12 categories of foods and nearly 200 individual foods.

The glycemic index is a scoring system which rates foods on a 0-100 basis according to their impact on digestion and insulin levels, based on the type of carbohydrates used. The glycemic index diet plan has become increasingly popular for wellness, weight loss, and has been particularly well received by pre-diabetics, diabetics, and those following a heart healthy cardiovascular health plan.

According to Wayne Mitchell of GlycemicEdge.com, the best part about the glycemic index diet is it’s realistic approach to choosing foods while not banishing carbs. “Low carb and no carb diets are really challenging to follow. They also don’t have the health benefits that “low GI” or good carb foods provide. With low glycemic foods, you get the benefit of feeling “fuller” with foods that put much less strain on your digestive system and pancreas, controlling the release of insulin.”

Another popular benefit for low glycemic foods is weight loss, as your metabolism adjusts and switches from primarily burning carbs as a fuel source to burning fat. Whole grains and complex carbohydrates are emphasized while simple carbohydrates and foods which result in a sudden, rapid insulin spike during digestion rank high on the GI scale and should be avoided.

“Our users love the ability to compare foods, find some surprising foods that are good low GI choices, and print and take lists with them when they do their shopping and planning for their families. About 70% of our users are moms planning for their families, and the charts and food lists are a great resource to make this easier for them.”

Users can print the lists for free and are invited to share questions and submit food scores of their own to help grow community awareness. Also featured are south beach diet food list and printable shopping guides.

 

diabetes cured in rats

From Diabeteshealth.com

Using stem cells that they extracted from the brains of diabetic lab rats, and turning them into insulin-producing pancreatic cells, Japanese scientists may be on the road to a virtual cure for diabetes that comes from people’s own brains. Led by Tomoko Kuwabara of the National Institute of Advanced Industrial Science and Technology in Tsukuba Science City, Japan, a team of scientists extracted neural tissue from the rats’ olfactory bulbs or their hippocampuses. The former is the part of the brain is involved with smell while the former is involved with memory.

Because of both sites’ location in the brain, extraction was easily done through the nose. The rats involved had either type 1 or type 2 diabetes. The scientists then extracted stem cells from the tissue and applied a human protein to them, Wnt3a, which “switches on” insulin production.

After two weeks, the cells had multiplied to the point that the researchers could lay collagen sheets impregnated with them gently on top of the diabetic rats’ pancreases. Seven days later, the concentration of insulin in the blood of all the rats, whether type 1 or type 2, matched that of non-diabetic rats. Blood glucose levels were normal.  To read the entire story on diabeteshealth.com, >Click Here.<

A team of Department of Veteran Affairs (VA) researchers were intrigued by studies that suggested that low levels of insulin in the brain could contribute to Alzheimer’s disease. The researchers, led by Dr. Suzanne Craft, decided to test the benefits of restoring normal insulin levels in the brains of Alzheimer’s patients.

Insulin is an important hormone which plays a major role in turning blood sugar into energy for cells. A lack of insulin, or an inability to properly use it, results in diabetes. Diabetes is a known risk factor for Alzheimer’s, although the connection is not yet clear.

Alzheimer’s is a disease in which cognitive functioning declines over time, causing progressive memory loss, loss of motor and language skills, impaired reasoning, emotional instability, and eventually full-blown dementia. The disease is associated with abnormal protein deposits in the brain called plaques. Read the full article

An inexpensive vaccine that’s been used for over 90 years to combat tuberculosis may have the ability to reverse type 1 diabetes. Although the early results were met with skepticism, seven studies in mice over the last ten years have established that the generic drug BCG (bacillus Calmette-Guerin) can prevent immune system T cells from destroying insulin-producing cells, allowing the pancreas to regenerate and once again produce insulin.

A research team from the Massachusetts General Hospital Immunobiology Laboratory led by Dr. Denise Faustman, PhD, successfully reproduced the results in a small group of human subjects, using very small doses of the vaccine. Those diabetics receiving the vaccine, all of whom had been Type 1 for an average 15 years, showed both a decrease in pancreas cell-destroying T cells, and an increase in the insulin precursor C-peptide – an indicator of insulin production.

American Idol runner-up singer/songwriter Crystal Bowersox has revealed that she was hospitalized for two days with diabetic ketoacidosis (DKA) during last year’s finals. Bowersox now admits to neglecting her disease, sometimes going an entire day without testing her blood sugar.

With her diabetes now under control, she currently checks her blood glucose levels at least 10 times a day. “When you know what your reading is, you know what to do,” says Bowersox, who now strives to be a good role model for fellow insulin dependent diabetics, “The only way you can live your life is by monitoring your diabetes.”

Bowersox, a type 1 diabetic since age 6, is now an advocate for the Juvenile Diabetes Research Foundation and the Diabetes Research Institute. Fellow Idol contestant Kevin Covais, also a type 1 diabetic, has joined Bowersox in her advocacy for both diabetes organizations.

DKA usually results from not monitoring and controlling blood sugar and insulin levels, especially around mealtimes. Insulin dependent diabetics also need to take into consideration their stress and activity levels when calculating the correct insulin dosage.

Scientists at the prestigious Mayo Clinic are excited about a promising prospective treatment for type 2 diabetes. Type 2 diabetes is a result of the body losing sensitivity to insulin and no longer being able to respond to it. Current diabetes treatments concentrate on increasing insulin levels – either by administering insulin injections, or by stimulating the pancreas to produce more insulin.

A Mayo Clinic Department of Neuroscience research team, led by Malcolm Leissring, Ph.D, took a different approach – blocking the breakdown of insulin after it was released by the pancreas. Conducting studies in mice, the researchers genetically deleted an insulin-degrading enzyme, or IDE, which breaks insulin down into smaller pieces to help control insulin levels in the blood.

The IDE-less rodents were “super mice” in regards to their ability to lower their blood sugar after a meal (a problem for many diabetics). They also had higher insulin levels, weighed less, and had better overall blood sugar control. Read the full article

There are complex cause and effect relationships between sleep and diabetes. Poor sleep is considered a risk factor for diabetes, while diabetes is considered a contributor to poor sleep.

Sleep disorders such as insomnia, excessive snoring and obstructive sleep apnea are more common in people with type 2 diabetes. As a result, many diabetics don’t sleep as well as people without the disease.

Recently, researchers conducting a study titled Cross-Sectional Associations Between Measure Of Sleep And Markers Of Glucose Metabolism Among Persons With And Without Diabetes” monitored the sleep patterns of 40 type 2 diabetics over six nights. They were first interviewed about their normal sleeping patterns, and blood samples were taken to measure their glucose and insulin levels. Read the full article

Diabetes is the most common cause of gastroparesis, or delayed gastric emptying. That’s because high blood sugar causes chemical changes in nerves, including the vagus nerve, which controls the movement of food through the digestive tract. High blood sugar also damages the blood vessels that carry oxygen and nutrients to the nerves, further impairing their functioning.

When the vagus nerve is damaged, then the passage of food through from the stomach through the digestive track slows, or even stops. People commonly suffer from a wide range of gastroparesis symptoms, making the condition difficult to diagnose. Frequency and severity of symptoms also vary widely from individual to individual. Common symptoms are: Read the full article
