Moderate coffee intake linked to slower biological aging in people with severe mental illness

Drinking a maximum of 3-4 cups of coffee a day may slow the 'biological' ageing of people with severe mental illness, by lengthening their telomeres-indicators of cellular ageing-and giving them the equivalent of 5 extra biological years, compared with non-coffee drinkers, finds research published in the open access journal BMJ Mental Health.

Daily walking patterns help flag early Parkinson’s signs in large UK study

Accelerometer data from nearly 95,000 adults show that higher daily step counts predict lower short-term Parkinson’s disease risk. But as follow-up extends, the association fades, indicating that reduced steps are more likely an early marker than a cause.

One cup of coffee a day could keep atrial fibrillation from coming back

A multicenter randomized clinical trial found that moderate caffeinated coffee intake after cardioversion significantly lowered the recurrence of atrial fibrillation or flutter compared with abstinence. The findings challenge long-standing advice to avoid coffee in cardiac arrhythmia patients and support its safety at typical consumption levels.

Mediterranean diet linked to dramatically lower odds of endometriosis

A new case–control study found that women with stronger adherence to the Mediterranean diet had dramatically lower odds of endometriosis. Diets rich in fruits, vegetables, fish, and legumes were protective, while higher intakes of meat, dairy, and refined whole grains were linked to increased risk.

Why your diet may be exporting extinction abroad without you knowing

This global analysis shows that the biodiversity impact of producing 1 kg of food can vary by up to 1,000-fold, with ruminant meat and tropical luxury crops carrying the highest extinction risks. Using the LIFE metric, researchers reveal how national diets and food imports contribute to hidden biodiversity losses, highlighting dietary shifts as a powerful conservation tool.
