Vitamin C linked to fewer deaths in blood disorder trial

Vitamin C may do more than support the immune system. In a phase 2 trial of people with precancerous or low risk blood cancers, daily vitamin C did not slow abnormal cell growth, but it was linked to favorable changes in inflammation and fewer serious complications. An exploratory follow up also found fewer deaths among participants taking vitamin C than among those receiving placebo.

Glucosamine, a popular joint supplement, linked to faster Alzheimer’s progression

A large health-record analysis found that glucosamine use was associated with a 25% higher likelihood of mild cognitive impairment progressing to dementia. Lab experiments suggest the popular joint supplement may intensify an abnormal sugar-tagging process in the Alzheimer’s brain, although researchers say clinical trials are needed to determine whether it actually causes harm.

Ultra-processed foods linked to hidden muscle fat that may threaten your knees

Eating more ultra-processed foods was linked to greater fat buildup inside thigh muscles, according to MRI scans of 615 adults at risk for knee osteoarthritis. Surprisingly, the association remained even after researchers accounted for calorie intake, physical activity, and other factors. Fatty changes in these muscles may weaken support around the knee and potentially increase osteoarthritis risk.
