Insulin News and Research

RSS

Insulin is a hormone that is needed to convert glucose, starches and other food into energy needed for daily life. Insulin allows cells to use glucose for fuel and is secreted by beta cells in the islets of Langerhans. The release of insulin from the pancreas is stimulated by increased blood glucose, vagal nerve stimulation, and other factors. Insulin is obtained from various animals and available in a variety of preparations. Commercial insulin preparations differ in a number of ways, including differences in the animal species from which they are obtained; their purity, concentration, and solubility; and the time of onset and duration of their biologic action. An oral hypoglycemic agent is not a form of insulin therapy.

Diabetes drug blunts exercise-induced health improvements

Do GLP-1 drugs cause cancer? New review says no, may even protect

A comprehensive review in The Journal of Clinical Investigation finds no overall link between GLP-1 receptor agonists and increased cancer risk, countering early safety concerns. Instead, evidence suggests possible protective effects for certain cancers, supported by metabolic and immune-modulating mechanisms.

GLP-1 drugs calm inflammation beyond diabetes and weight loss

This Journal of Clinical Investigation review describes how glucagon-like peptide-1 (GLP-1)–based medicines reduce systemic and tissue inflammation through both weight-dependent and weight-independent mechanisms. It details preclinical and clinical evidence linking GLP-1 receptor activation to cardiovascular, renal, hepatic, neural, and joint anti-inflammatory effects while outlining uncertainties and future research needs.

Scientists explore why black rice deserves a bigger place in modern diets

Researchers reviewed the nutritional composition, therapeutic benefits, and industrial uses of black rice, highlighting its potential as a functional food. The study highlights the role of black rice in managing blood sugar, cholesterol, and inflammation, while also advocating for more robust human trials and sustainable cultivation methods.

Does fasting earlier in the day improve metabolism? This study says no

In a randomized crossover trial of 31 women with overweight, early and late time-restricted eating (TRE) produced no improvement in insulin sensitivity or cardiometabolic markers under isocaloric conditions. Both schedules, however, shifted internal circadian clocks, highlighting that meal timing affects biological rhythms more than metabolic outcomes.

Diabetes remission possible with GLP-1 drugs, Italian study confirms

In a large real-world Italian cohort, GLP-1 receptor agonist therapy led to measurable rates of type 2 diabetes remission, depending on how remission was defined. The most pragmatic definition (Remission 3) was linked to improved glycemia, weight, and a lower risk of microvascular and cardiovascular events.

Aligning your body clock may protect your heart and metabolism, says AHA

A new American Heart Association scientific statement highlights how maintaining circadian health through regular sleep, light exposure, meal timing, and exercise may reduce cardiometabolic disease risk. Disrupting these daily rhythms can impair glucose regulation, blood pressure, and cardiovascular function.
