Scientists warn a popular vitamin D supplement may have a hidden downside

6 days ago
Not all vitamin D supplements are created equal, and new research suggests that one popular form may have an unexpected downside. Scientists found that taking vitamin D2 can actually lower the body's levels of vitamin D3, the form naturally produced by sunlight and more effective at boosting overall vitamin D. Previous studies also suggest that vitamin D3 may provide stronger immune protection against viruses and bacteria.

Not all trans fats are bad, major review finds

6 days 1 hour ago
A large analysis of 22 studies found that the trans fats naturally present in dairy foods such as milk, butter, yogurt, and cheese do not appear to raise the risk of heart disease or type 2 diabetes. Unlike industrial trans fats from partially hydrogenated oils, dairy trans fats showed no meaningful harmful effects on blood fats in controlled trials and were not linked to higher rates of heart disease, stroke, cardiovascular death, or diabetes in long-term studies.

Dads are dying after their kids are born, and almost no one is tracking it

A study of more than 130,000 babies born in Georgia found that hundreds of fathers died within the first five years of their child’s life, and about 60% of those deaths were potentially preventable. Homicide, accidental injuries, suicide, and drug overdoses accounted for most of the preventable deaths, highlighting what researchers call a major blind spot in public health.

Stanford scientists turn a cancer driver into a kill switch

6 days 3 hours ago
A Stanford-designed molecule turns a major lymphoma-promoting protein against cancer cells, activating their own self-destruct machinery instead of simply blocking tumor growth. In mice, the treatment completely eliminated aggressive human lymphoma tumors within 11 days, although much more testing is needed before it could reach patients.

Taking antibiotics? Sugar may be making the damage worse

Eating more sugar while taking antibiotics was linked to greater disruption of the gut microbiome and increased growth of potentially harmful bacteria. Researchers say temporarily cutting back on sweets during and after antibiotic treatment could be a simple way to reduce this damage, though clinical trials are still needed.
