Planetary Health Diet may work through gut bacteria to support aging
A review examines how the Planetary Health Diet might help people age better by changing gut bacteria composition and function. The diet is linked to greater bacterial diversity, better immune responses, and lower risks of heart disease and frailty in studies.
Why it matters: Understanding how diet affects aging through gut bacteria could help design nutrition strategies for both human and environmental health.
Keep in mind: This is a narrative review synthesizing existing evidence, not new research, so it cannot establish cause-and-effect or identify mechanisms the original studies did not measure.
