That Anxiety May Be In Your Gut, Not In Your Head

From a 17 May 2011 Medical News Today article

For the first time, researchers at McMaster University have conclusive evidence that bacteria residing in the gut influence brain chemistry and behaviour.

The findings are important because several common types of gastrointestinal disease, including irritable bowel syndrome, are frequently associated withanxiety or depression. In addition there has been speculation that some psychiatric disorders, such as late onset autism, may be associated with an abnormal bacterial content in the gut.

“The exciting results provide stimulus for further investigating a microbial component to the causation of behavioural illnesses,” said Stephen Collins, professor of medicine and associate dean research, Michael G. DeGroote School of Medicine. Collins and Premysl Bercik, assistant professor of medicine, undertook the research in the Farncombe Family Digestive Health Research Institute.

The research appears in the online edition of the journal Gastroenterology. ….

Cell Phones Can Help Under-Developed Countries Manage Diabetes And Other Diseases

From a 17 May 2011 Medical News Today article

A new study by the Veterans Affairs Ann Arbor Healthcare System and University of Michigan suggests that mobile phones could help low-income patients across the globe manage diabetes and other chronic diseases. ..

…For this study, researchers took advantage of the broad penetration of cell phones in Latin America and paired them with low-cost internet-based phone calls. The service used a cloud computing approach so that the program can be provided from a central location to low income countries around the globe that lack a strong technological infrastructure.

To test the service, the researchers enrolled patients with diabetes from a clinic in a semi-rural area of Honduras. Patients received weekly, automated, interactive phone calls and overwhelmingly reported that the program helped them to improve their diabetes management and general health.

Over the six-week study, researchers saw a clinically important improvement in patients’ hemoglobin A1C, a measure of blood sugar control. The results are forthcoming in the June issue of the American Journal of Preventive Medicine. ….

Pediatrics Professor Calls Sugar Toxic in a Heavily Viewed 2009 YouTube Lecture

Excerpts from a 13 April 2011 New York Times article

On May 26, 2009, Robert Lustig gave a lecture called “Sugar: The Bitter Truth,” which was posted on YouTube the following July. Since then, it has been viewed well over 800,000 times, gaining new viewers at a rate of about 50,000 per month, fairly remarkable numbers for a 90-minute discussion of the nuances of fructose biochemistry and human physiology….

..by “sugar,” Lustig means not only the white granulated stuff that we put in coffee and sprinkle on cereal — technically known as sucrose — but also high-fructose corn syrup, which has already become without Lustig’s help what he calls “the most demonized additive known to man.”….

…The fructose component of sugar and H.F.C.S. is metabolized primarily by the liver, while the glucose from sugar and starches is metabolized by every cell in the body. Consuming sugar (fructose and glucose) means more work for the liver than if you consumed the same number of calories of starch (glucose). And if you take that sugar in liquid form — soda or fruit juices — the fructose and glucose will hit the liver more quickly than if you consume them, say, in an apple (or several apples, to get what researchers would call the equivalent dose of sugar). The speed with which the liver has to do its work will also affect how it metabolizes the fructose and glucose….

..If Lustig is right, then our excessive consumption of sugar is the primary reason that the numbers of obese and diabetic Americans have skyrocketed in the past 30 years. But his argument implies more than that. If Lustig is right, it would mean that sugar is also the likely dietary cause of several other chronic ailments widely considered to be diseases of Western lifestyles — heart disease, hypertension and many common cancers among them….

This  long article goes on to explain how it is believed that an excessive sugar intake leads to fatty livers and accompanying metabolic syndrome. The body, in its inability to use naturally produced insulin, sets the stage for diabetes, high blood pressure, and even cancer.
