Connections between metabolism and cell stress control may inform study of diabetes, cancer
How our bodies handle glucose—the simple sugar that provides energy from the food we eat—appears to be intertwined with how cells keep themselves functioning normally, according to new University of Chicago research. (more…)
ANN ARBOR — It’s obvious that the taste buds on the tongue can detect sugar. And after a meal, beta cells in the pancreas sense rising blood glucose and release the hormone insulin—which helps the sugar enter cells, where it can be used by the body for energy. (more…)
ANN ARBOR—We’ve all been there: We eat an entire sleeve of fat-free, low-calorie cookies and we’re stuffing ourselves with more food 15 minutes later. (more…)
For the first time, scientists have used new technology which analyses the whole genome to find the cause of a genetic disease in what was previously referred to as “junk DNA”.
Pancreatic agenesis results in babies being born without a pancreas, leaving them with a lifetime of diabetes and problems digesting food.
In a breakthrough for genetic research, teams led by the University of Exeter Medical School and Imperial College London found that the condition is most commonly caused by mutations in a newly identified gene regulatory element in a remote part of the genome, which can now be explored thanks to advances in genetic sequencing.

A new technique for detecting cancer by imaging the consumption of sugar with magnetic resonance imaging (MRI) has been unveiled by UCL scientists. The breakthrough could provide a safer and simpler alternative to standard radioactive techniques and enable radiologists to image tumours in greater detail.
The new technique, called ‘glucose chemical exchange saturation transfer’ (glucoCEST), is based on the fact that tumours consume much more glucose (a type of sugar) than normal, healthy tissues in order to sustain their growth. (more…)
Sugar isn’t always sweet to German cockroaches, especially to the ones that avoid roach baits.
In a study published May 24 in the journal Science, North Carolina State University entomologists show the neural mechanism behind the aversion to glucose, the simple sugar that is a popular ingredient in roach-bait poison. Glucose sets off bitter receptors in roach taste buds, causing roaches to avoid foods that bring on this taste-bud reaction. This aversion has a genetic basis and it eventually spreads to offspring, resulting in increasingly large groups of cockroaches that reject glucose and any baits made with it.
In normal German cockroaches, glucose elicits activity in sugar gustatory receptor neurons, which react when exposed to sugars like glucose and fructose – components of corn syrup, a common roach-bait ingredient. Generally, roaches have a sweet tooth for these sugars. (more…)
Researchers at the University of Montreal have found that the glycated hemoglobin levels of children with type 1 diabetes followed at its affiliated Sainte-Justine Mother and Child University Hospital (CHU Sainte-Justine) is correlated linearly and negatively with household income. Glycated hemoglobin is the binding of sugar to blood molecules – over time, high blood sugar levels lead to high levels of glycated hemoglobin, which means that it can be used to assess whether a patient properly controls his or her blood glucose level. “Our study highlights a marked disparity between the rich and the poor in an important health outcome for children with type 1 diabetes, despite free access to health care”, explained Dr. Johnny Deladoëy, who led the study.

Most people today look at diet plans to help them lose weight; however, these plans can also serve other purposes such as keeping heart disease and diabetes at bay. With all the different diet plans on offer, choosing the one that is right for you can be a tough job. Take a look at these plans that were evaluated by health experts and received high rankings in a recent survey by U.S. News, and make your decision.
The Mediterranean Diet
Like the Mayo Clinic Diet, the Mediterranean Diet plan helps to achieve and maintain a healthy weight and also prevent or control diabetes, brain and heart disorders and even cancer. Drawing inspiration from the diet of people in the European countries around the Mediterranean Sea, this diet focuses on eating more of nuts, herbs and spices, whole grains, vegetables and fruits, seafood and fish, and cutting down on red meat, saturated fat foods and sugar. With its emphasis on mono- and polyunsaturated fats and avoidance of saturated fat, this diet is effective at reducing bad cholesterol and keeping blood pressure low. Although it is one of the top diet programs, the only possible weakness lies in the fact that the plan is not a structured one and so, the onus lies on you to come up with a calorie chart to follow.
