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.

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.

The basics In the simplest terms, diabetes means having too much glucose in your blood. Glucose is a type of sugar and a source of energy for the body. But if insulin, glucose’s “traffic cop,” isn’t doing its job, glucose accumulates in the bloodstream and all sorts of health problems can occur. Normally, most of the food a person eats gets converted into glucose, the body’s energy of choice. The circulatory system shuttles the glucose around so that hungry cells in the muscles, liver and elsewhere can snatch it out of the blood as it passes by. The liver cells are the hungriest for that glucose, because the liver is the body’s between-meal glucose storage facility.

Young and diabetic: An article in Monday's Health section, about an 8-year-old with Type 1 diabetes, said that one day when she felt shaky, a test found her blood glucose "a bit higher than normal" and her mother recommended a glucose tablet. In fact, the level was lower than normal. A glucose tablet wouldn't be given for high blood glucose.
