Glucose

Many food activists and public health researchers are ready to pin a substantial portion of blame for the nation's obesity epidemic on the skyrocketing consumption of high-fructose corn syrup, widely used to sweeten processed foods and beverages in the U.S. since the 1980s. But food and beverage makers are fighting back . Glucose and fructose are both simple sugars--and equal parts of each is the recipe for table sugar. (High-fructose corn syrup is a bit more intensely sweet because it's made up of 55% fructose.)

People with elevated blood sugar levels - even those not high enough for diabetes or pre-diabetes - are more likely to have memory problems than people with lower levels, a study of 141 people has shown. The results suggest that people within the normal range could help prevent cognitive problems as they age by lowering their blood sugar levels, said the author of the study, Agnes Floel of Charite University Medicine in Berlin. The work was published online Wednesday in the journal Neurology.

Fingertip pricks serve their purpose in helping people with diabetes monitor their blood sugar levels. But, come on, it would be nice to have a method that doesn't involve drawing blood. Researchers reported progress this week on a technology that would provide non-invasive, continuous blood glucose monitoring. The technology uses microbeads coated with a fluorescent dye that are designed to bind with glucose molecules. The beads are injected into the body, and the sensing dye provides a continuous readout of glucose levels measured across the skin from the fluorescent intensity.

Nova Diabetes Care is recalling up to 62 million glucose test strips that show an incorrect high sugar level reading, the U.S. Food and Drug Administration said Wednesday. The voluntary recall was announced by the company Friday for products sold as under the brand names of Max Blood Glucose Test Strips and Nova Max Plus Glucose Meter Kits. The strips were sold in the U.S. and in 13 countries and Puerto Rico, the FDA said in statement.

UC San Diego researchers have developed an implantable glucose sensor for diabetics that has worked for a year in pigs and that could be a major step forward toward the development of an artificial pancreas. As many as 800,000 people already use external insulin pumps that, through programming, inject a continuous background level of insulin and higher jolts at mealtimes or when a physical blood test indicates. The goal of many researchers has been to develop a continuous glucose monitor that can be implanted and send electronic signals to control how much insulin the pump secretes, thereby mimicking the action of the pancreas.

Abbott Laboratories said Monday that it had received approval from the Food and Drug Administration for a new blood glucose monitoring system -- an announcement that came as its stock rose to a six-month high. The go-ahead added to Abbott's momentum after the release of positive results from the first trial of its ZoMaxx device, a drug-coated stent intended to unclog arteries to the heart, Sunday at the American College of Cardiology's annual meeting in Atlanta.

The can-you-be-fit-and-fat debate just got more fuel courtesy of a study presented recently at the annual scientific meeting of the American College of Gastroenterology in San Diego. Researchers zeroed in on football players, especially linemen, to determine whether they have greater risk factors for cardiovascular diseases and Type 2 diabetes: high blood pressure, high cholesterol and high fasting blood glucose levels. The study included 69 professional football players and 155 professional baseball players, all currently playing.

Michel Montignac, a French businessman turned diet guru who believed people could lose weight without counting calories, has died. He was 66. Montignac died Aug. 22 at a clinic in Annemasse, France. His website and a website for his daughter, Sybille, confirmed the death but no other details were disclosed. "You know French people don't exercise and also we don't count calories … at least to the extent Americans do," Montignac told "CBS This Morning" in 1993 after he opened a restaurant in Paris.

High-fructose corn syrup is often singled out as Food Enemy No. 1 because it has become ubiquitous in processed foods over about the last 30 years – a period that coincides with a steep rise in obesity. One of the primary sources of HFCS in the American diet is soda – in fact, many public health advocates refer to soda as “liquid candy.” That nickname is more apt than advocates realized, according to a study published online this month by the journal Obesity.

In the war against pests, the lowly cockroach makes for a fearsome adversary. It can go weeks without water, survive decapitation for a time - and, like any proper super-villain, can send humans screaming from a room. Now researchers have discovered how some roaches have eluded humans' once-infallible traps: They have evolved so that glucose-sweetened bait tastes bitter. The discovery, published in Friday's edition of the journal Science, solves a 20-year mystery and sheds light on the cockroach's powerful ability to adapt.

When James Watson and Francis Crick deciphered the structure of DNA in 1953, their discovery answered a crucial question in biology: How is genetic information passed down from parent to child? Their work also created conundrums, however. They and others showed that every cell of an organism contains all of its genetic material. How, then, does an individual cell know which genes to use and when? And how does information from DNA get to the cell's protein-making machinery? The seminal insight into those questions came from three biologists at the Pasteur Institute in Paris - Dr. Francois Jacob, Jacques Monod and Andre Lwoff.

After gastric bypass surgery, people with  Type 2 diabetes often see their disease completely  disappear  - within weeks, before they've lost much or any weight. It doesn't work for everyone, though.  What are the factors that matter? A study by a team of scientists from the University of Massachussetts looked into that. Here are their findings, which were presented at the annual meeting of the American Society for Metabolic and Bariatric Surgery. The scientists looked at remission of diabetes in 139 patients, ages 48 to 57, who'd had gastric bypass surgery.

Diabetes affects more than 25 million Americans. New medications and strategies to treat the disease are greatly needed. But the jury is still out on the experimental medication dapagliflozin. The medication looks to have significant benefits and risks, according to a study published Monday. Dapagliflozin is being developed by Bristol-Myers-Squibb Co. in partnership with AstraZeneca. It represents a new class of diabetes medications called selective renal sodium glucose contransporter inhibitors.

A short while ago, Lars came in for a visit. He's a friendly, happy-go-lucky guy with a desk job in some sort of marine industry. The bulk of his visits have revolved around his passion for softball. He plays on three teams year round, and from time to time his competitive edge gets the better of him and he twists an ankle or pulls a muscle and comes in to get patched up. I remind him he's 45, not 25, that it's not Game 7 of the World Series, that he should go a little easy on himself.

Smart phones have already supplemented the doctor’s office and personal computers as sources of health advice — and now it appears car companies are driving into the on-the-go consumer health market. Ford is developing a way to display pollen counts and other allergen levels to drivers using its existing link to smart phone apps, the car company announced Wednesday. Ford has also made a prototype to synchronize glucose monitoring devices via Bluetooth. The car displays glucose levels and sounds an alert if they fall too low. A statement from Ford explains how this technology can help diabetics and allergy sufferers: “For people with diabetes and their caregivers, constant knowledge and control of glucose levels is critical to avoiding hypoglycemia or low glucose, which can cause confusion, lightheadedness, blurry vision and a host of other symptoms that could be dangerous while driving.

Young diabetic: An article in the Oct. 26 Health section, about a young girl with diabetes, recounted an experience in which she felt shaky, tested her blood glucose, found it to be higher than normal and then took a glucose tablet. In fact, her blood glucose was lower than normal, not higher, resulting in the shaky feeling and the need for a glucose tablet. Such a tablet wouldn't be given for high blood glucose.

Other than driving a race car 200 mph while monitoring a life-threatening illness, Charlie Kimball is a normal guy. Kimball will drive in the Toyota Grand Prix of Long Beach on Sunday. He is 26 and is two races into his rookie season on the Izod IndyCar circuit. He already has a top-10 finish, and is somebody with almost unlimited promise for a lucrative racing future on the highest level. Except for the diabetes. "It was Oct. 16, 2007," Kimball recalls. "I went to a doctor because I had a skin rash.

Yes, he's had numerous stints on reality TV and millions of records sold -- but singer Bret Michaels may be best known as the star of a real-life medical drama. In April 2010, he had an emergency appendectomy. Less than two weeks later, he had a brain hemorrhage. A month after that, he had a stroke, caused by a hole in his heart. He had surgery to repair the heart defect in January. Michaels also has Type 1 diabetes, which was diagnosed when he was 6 years old. He spoke about how he deals with that disease in a recent interview with Diabetes Health magazine.
