Eat well, age well; microplastics and chronic disease; ‘about me’ care cards support cognitive health conversations – Morning Medical Update

Eat well, age well

A new 30-year study suggests that a plant-forward diet with minimal processed foods significantly boosts the chances of reaching 70 without chronic diseases like diabetes or heart disease. Researchers analyzed over 105,000 people and found that those following diets rich in fruits, vegetables, whole grains, and healthy fats — such as the Mediterranean diet — had up to an 86% greater likelihood of healthy aging. The study, published in Nature Medicine, reinforces the importance of diet quality over strict food restrictions, showing that even moderate consumption of fish and dairy can be beneficial. While diet plays a crucial role, experts emphasize that exercise, stress management, and avoiding smoking are also key factors in aging well. NBC News has more.

Microplastics linked to higher rates of chronic disease

New research presented at the American College of Cardiology’s Annual Scientific Session suggests that exposure to microplastics is associated with an increased prevalence of hypertension, diabetes and stroke. The study analyzed pollution data from coastal areas and found that higher concentrations of microplastics correlated with higher rates of these chronic diseases. While the findings don’t confirm causation, researchers stress the importance of reducing plastic use and exposure. Another study presented at ACC.25 linked microplastics in arterial plaques to cardiovascular risks. More research is needed to understand the full impact of microplastics on human health.

‘About me’ care card supports cognitive health conversations

A new study published by the American Academy of Family Physicians highlights the potential of the “About Me” Care Card in improving care planning for older adults with cognitive concerns. The tool, developed with input from clinicians, caregivers and patients, facilitates discussions about personal fears, goals and social needs — areas often overlooked in cognitive impairment assessments. Piloted across seven institutions, the card helped personalize care conversations, though patients with advanced cognitive challenges needed assistance. While 65% of users recommended it, only 32% felt it contributed to a concrete care plan. Researchers suggest integrating the tool into primary care could enhance early identification of patient concerns.
