Using Britain’s postwar sugar rationing as a natural experiment, researchers found that lower early-life sugar exposure tracked with less cancer and slower biological aging decades on — though it can’t prove cause.
In 340,000 UK adults, low-to-moderate wine drinking was tied to lower heart-death risk while beer and spirits were tied to higher — but it’s observational, not proof.
In a 170-patient, placebo-controlled study, dronabinol cut nightmare severity more than placebo — though it did not clearly reduce overall PTSD or depression.
At very high intravenous doses, vitamin C flips from antioxidant to pro-oxidant, generating a compound that preferentially damages stressed cancer cells. It’s still experimental.
A new analysis of grocery data suggests banning soda from food-assistance benefits cut soda buying — but shoppers redirected much of the money to other sugary drinks.
A 12-week randomized study in adults with overweight found three daily servings of full-fat dairy didn’t harm cholesterol or body composition — but it was short and industry-funded.
A French randomized trial found healthy, low-risk people over 75 who stopped their preventive statins were no worse off on death or heart events over three years — with big caveats.
A large study of over 21,000 women found those who used estrogen-only menopausal hormone therapy had less dementia and less Alzheimer’s pathology — but it’s an association, not proof.
In a six-year study of older adults, having both abdominal obesity and low vitamin D was tied to more than double the risk of death — each condition amplifying the other.
A study of 402 adults found that physical activity and controlled blood sugar in midlife were associated with better preserved thinking skills decades later.
A large Swedish study tracked hundreds of thousands of people and found that those who actually completed a mailed stool test were far less likely to die of colorectal cancer.
New data add to the case that simpler two-drug therapy works as well as the standard three-drug combination for people starting HIV treatment.
