Type 2 Diabetes

Type 2 diabetes, formerly called adult-onset or noninsulindependent diabetes, is the most common form of diabetes. People can develop type 2 diabetes at any age, even during childhood. This form of diabetes usually begins with insulin resistance, a condition in which fat, muscle, and liver cells do not use insulin properly. At first, the pancreas keeps up with the added demand by producing more insulin. In time, however, it loses the ability to secrete enough insulin in response to meals. People who are overweight and inactive are more likely to develop type 2 diabetes. Treatment includes taking diabetes medicines, making wise food choices, exercising regularly, controlling blood pressure and cholesterol, and taking aspirin daily—for some.

What is Type 2 Diabetes?

Type 2 diabetes is a common metabolic condition that develops when the body fails to produce enough insulin or when insulin fails to work properly, which is referred to as insulin resistance. Insulin is the hormone that stimulates cells to uptake glucose from the blood to use for energy.

Major studies identify accurate non-invasive tests for liver disease

Two major international studies have delivered the strongest evidence to date on which non-invasive tests can accurately diagnose and measure the severity of metabolic dysfunction-associated steatotic liver disease (MASLD) and its more severe form, MASH, reducing reliance on liver biopsy.

Can broccoli sprouts help with insulin resistance? New review offers clues

A review published in the British Journal of Nutrition examines how carotenoids and bioactive compounds in Brassicaceae microgreens may influence obesity, insulin resistance, and type 2 diabetes through metabolic and inflammatory pathways. Small human trials involving broccoli sprouts have reported improvements in selected metabolic markers, but larger, longer-term studies are needed to establish their clinical benefits.

CT scans linked vitamin D levels to fat within muscles after bariatric surgery

Researchers followed 113 adults for one year after bariatric surgery and found that those with higher postoperative vitamin D concentrations had less fat infiltration within certain muscles and lower visceral adiposity. They found no significant association between increases in vitamin D and changes in body composition after correction for multiple comparisons, while preoperative vitamin D levels did not independently predict postoperative body composition.

Men with lower testosterone at 31 reported good health 15 years later

Researchers analyzed testosterone concentrations measured at age 31 in 2,691 Finnish men and assessed self-reported health, medical conditions, and quality of life at age 46. Men across testosterone quartiles generally reported good health and excellent quality of life, while differences in metabolic and gastrointestinal conditions lost statistical significance after adjustment for waist circumference.

High-scoring endocrinologists are more likely to prescribe key diabetes drugs

Endocrinologists who scored highest on the American Board of Internal Medicine's Longitudinal Knowledge Assessment (LKA®) were more likely to prescribe a key diabetes drug class following a treatment guidelines update compared to doctors with lower scores.

High intake of saturated fat can promote favorable changes in cardiovascular risk markers

New analyses from the Norwegian randomized controlled trial CARBFUNC show that more than doubling saturated fat intake over a two-year period can promote favorable changes in several cardiovascular risk markers, without increasing apoB, the main suspected risk factor.

Taking a GLP-1 drug? Here's what the safety evidence really shows

A review on GLP-1 receptor agonists highlights risks like pancreatitis and thyroid cancer, emphasizing individual patient risk over general safety concerns.

Children's brain reward responses may explain ultra-processed food-related weight gain

Children who eat more ultra-processed foods (UPFs) show stronger responses in the brain's reward network when viewing images of appetizing foods-and these brain responses are linked to increases in body fat one year later.

A study of 802 teens raises questions about school breakfast and blood sugar

A study of 802 U.S. adolescents found that school breakfast participation at least once weekly was associated with a 30% higher prevalence of prediabetes-range glucose markers, while school lunch participation showed no significant association. Higher intakes of vitamins E and B6 and fruit consumption among adolescents with obesity were associated with lower prediabetes prevalence, but none of the reported associations remained statistically significant after correction for multiple comparisons.

Beef can fit into healthy diets, but what about its environmental cost?

A narrative review published in Animal Frontiers highlights beef's contribution to high-quality protein and bioavailable micronutrients, while controlled trials generally found no adverse effects on selected cardiometabolic risk markers, although long-term disease outcomes remain uncertain. The authors argue that sustainable food policies should consider nutritional needs, environmental impacts, agricultural productivity, and rural livelihoods when evaluating beef's place in healthy diets.

Scientists found a link between Mediterranean diet blood markers and longer survival

Researchers found that a previously validated 67-metabolite blood signature of Mediterranean diet adherence was associated with lower long-term mortality across a Spanish trial population and three US cohorts. Participants with the highest signature scores had a 23% lower relative hazard of death than those with the lowest scores in both populations, although the findings do not establish a causal relationship.

Could eating whey protein before meals help reduce blood sugar spikes?

A narrative review of 57 randomized trials found that milk and dairy products have inconsistent effects on long-term blood sugar control in adults with type 2 diabetes or prediabetes. Whey protein consumed before meals more consistently reduced short-term blood sugar spikes, but further research is needed to establish whether these benefits persist over time.
