A recent research suggests that people with high blood sugar experience worse long-term cognitive decline compared to their peers with the normal level of blood sugar.
For their study, a team of researchers tracked 5,189 participants, including 55% women, whose average age was 66 years. They analyzed their level of cognitive function between 2004–2005 and 2014–2015. Over time, the scientists monitored levels of HbA1c, or glycated hemoglobin, a measure of blood sugar control.
The analysis of the received data showed that participants with greater levels of HbA1c experienced much higher rate of decline.
The researchers, led by epidemiologist Wuxiang Xie from Imperial College London, explain in their paper: “Our findings suggest that interventions that delay diabetes onset, as well as management strategies for blood sugar control, might help alleviate the progression of subsequent decline over the long-term.”
Some may think that eating too much fruit is not very good for your health because it contains too much sugar. However, a new research, led by Oxford University, discovered that fresh fruit does not increase blood sugar. The scientists think that this is due to glucose and fructose are metabolized differently to the refined sugars found in processed foods.
For the study, the researchers monitored around 500,000 people in China and found that those who were diabetes-free at the beginning of the 7-year experiment had 12% lower risk of developing diabetes if they consumed fruit every day.
Study authors and the lead author Dr. Huaidong Du at Oxford say: “These findings suggest that a higher intake of fresh fruit is potentially beneficial for primary and secondary prevention of diabetes.”
A team of scientists from the Seoul National University, South Korea, developed a sensor that can monitor blood sugar level by analyzing sweaty skin.
The patch has three sensors. It is flexible and can move with the skin. Human sweat contains less sugar than blood and other chemicals, so the scientists needed to overcome a series of challenges to make the patch work.
Inventing the patch, the scientists were trying to overcome the need for painful blood collection. In their study, the researchers conclude: “The current system provides important new advances toward the painless and stress-free care for diabetes”.
Scientists developed a transparent sensor for contact lenses that soon will be able to monitor the glucose level in patients with diabetes.
This transparent sensor has been developed by the researchers from Oregon State University, USA. It uses a nanostructured transistor that can detect subtle glucose changes in physiological buffer solutions like the tear fluid in eyes. Such sensors will be able to transmit real-time information about blood sugar level to a wearable pump delivering the hormones that are necessary for blood sugar regulation.
Greg Herman, a professor at Oregon State University, says: “We have fully transparent sensors that are working. We can integrate an array of sensors into the lens and also test for other things: stress hormones, uric acid, pressure sensing for glaucoma, and things like that.”
