A recent study has found that the Humanin peptide protects against neuronal cell death and regulates insulin metabolism, significantly improving glucose levels in diabetic rats. The discovery provides new insight into the role of the brain in glucose metabolism and suggests a potential therapeutic approach to diabetes.
A study found that consuming fructose-sweetened beverages increased intraabdominal fat and decreased insulin sensitivity, while glucose-sweetened beverages had no significant effects. This suggests that fructose may be more detrimental to health than glucose.
Researchers at Joslin Diabetes Center have discovered that subcutaneous fat, typically found in the hips and thighs, can lower insulin levels and enhance insulin sensitivity. This discovery offers a new avenue for finding substances produced by subcutaneous fat that may improve glucose metabolism.
Research suggests that insulin inhibits resistin expression and secretion in adipocytes, but resistin induces cellular insulin resistance in hepatocytes and myoblasts. Serum resistin levels correlate negatively with insulin sensitivity in diet-induced obesity rats.
A new study found that overweight type 2 diabetes patients who consumed moderate amounts of sugar from carrot cake experienced no adverse changes in blood glucose levels. The study, conducted over 24 days, showed improved insulin sensitivity and balanced energy intake.
A recent study found that suppressing slow-wave sleep in healthy young adults significantly decreases their ability to regulate blood-sugar levels. After only three nights of selective slow-wave sleep suppression, subjects became less sensitive to insulin, resulting in reduced tolerance to glucose and increased risk for type 2 diabetes.
Researchers found that low doses of resveratrol improve insulin sensitivity in mice, reducing the risk of type 2 diabetes. The study suggests that foods enriched with resveratrol or supplemented with the chemical may be a better option for improving insulin sensitivity.
A study by the University of Copenhagen found that soccer players experienced greater improvements in fitness ratings and muscle mass compared to joggers. The researchers attribute this to the shifts between walking, running, and sprinting in soccer, which engages multiple muscle fibers.
A Yale-developed weight management program cut diabetes risk and improved BMI in overweight children by increasing insulin sensitivity and reducing body fat. The Bright Bodies program, which combined nutrition education, behavior modification, and exercise, was more effective than traditional clinic-based counseling.
A study at the University of Illinois Chicago found that pioglitazone significantly slowed the thickening of carotid artery walls, reducing the risk of heart attack. The medication was shown to be effective regardless of age, sex, or diabetes duration.
miR-278 plays a crucial role in regulating insulin sensitivity in flies, with reduced insulin sensitivity and elevated blood glucose levels observed in flies lacking this microRNA. The study highlights the importance of microRNAs in metabolic regulation.
The study found that SOCS-7-deficient mice have increased IRS protein levels and prolonged IRS activation, leading to enhanced insulin action and glucose homeostasis. The researchers also observed increased growth of pancreatic islets with elevated fasting insulin levels and hypoglycemia.
A two-week course of fenofibrate treatment has significantly improved whole body glucose uptake and insulin sensitivity in pediatric burn victims, reducing morbidity outcomes and healing rates. The study showed that treating insulin resistance directly can aid recovery from general trauma, illness, or surgery.
Research by Martin Muurling found that mice on low-fat diets were more sensitive to insulin, suggesting a low-fat diet may be a more effective remedy for diabetes. The study also showed that consuming fish oil had no positive effects on reduced insulin sensitivity.
Recent studies show that overweight Hispanic youth are at an increased risk for developing type 2 diabetes and cardiovascular disease. Insulin resistance directly contributes to the development of metabolic syndrome, particularly in those with a family history of diabetes.
A study of Latino children found that nearly three in ten have impaired glucose tolerance, a precursor to type 2 diabetes, while obesity rates are twice those of non-Latino peers. Insulin resistance and metabolic syndrome increase the risk of chronic diseases.
A Mayo Clinic study found that middle-aged and older adults who engage in regular aerobic exercise can maintain increased insulin sensitivity for up to four days after their last workout. However, this effect is not seen in those over 40, highlighting the importance of frequent exercise for preventing or treating Type 2 diabetes.
A study of 289 teenagers found that cardiovascular fitness and lower body fat are independently associated with greater insulin sensitivity. Improving fitness or reducing body fat could protect high-risk children from developing insulin resistance, a precursor to diabetes.
A University of Otago study found that intensive exercise and specific dietary changes can improve insulin sensitivity by up to 20% in otherwise-healthy individuals. The research, which included 79 participants aged 35-60, also showed a significant improvement in insulin action among Māori participants.
A study by Raben et al. found that postobese women have different metabolic profiles than never obese women, with greater insulin sensitivity and more efficient triacylglycerol storage. This suggests that weight loss may not entirely eliminate the risks associated with obesity.
Recent advances in diabetes treatment have improved blood sugar control, allowing patients to dodge complications until late life. New drug therapies, including metformin and insulin analogs, have enhanced treatment possibilities.
Researchers found that participants with high insulin resistance were more likely to develop high blood pressure, highlighting a potential new treatment target. The study also suggests that reducing insulin resistance may help prevent hypertension and cardiovascular disease.
