Reacción a "A large-scale study reinforces the link between following an environmentally friendly diet and lower mortality rates"

This is a high-quality study, as it combines two of the largest available cohorts —NHANES in the U.S. and the UK Biobank— with a meta-analysis of more than three million participants, providing unusual robustness for nutrition research. Its conclusions —that higher adherence to the Planetary Health Diet is associated with lower mortality and reduced chronic-disease risk— are consistent with previous evidence and reinforce the idea that what is good for human health is also good for the planet. Limitations include the observational nature (no proof of causality) and limited generalizability across all social and cultural contexts. In Spain, where the Mediterranean pattern still has a footprint, the findings support lower red/processed meats and more fruits, vegetables, legumes, and whole grains. The key takeaway is that these shifts improve health and help mitigate climate change.

This large study shows that following the Planetary Health Diet is linked to lower premature mortality and fewer chronic diseases — and strikingly, it benefits both people and the planet.
