The Planetary Health Diet promotes environmentally sustainable consumption, based, among other things, on increasing vegetable intake and reducing dairy and red meat consumption. Previous studies had found an association with better human health, although there were some conflicting results. Now, a study combining two cohorts of more than 150,000 people and a meta-analysis of 37 studies involving more than three million volunteers reinforces this association, finding that greater adherence to the diet is associated with lower all-cause mortality. The results are published in the journal Science Advances.

People who eat more ultra-processed foods have a "slightly higher" mortality rate, according to an analysis published in The BMJ. The study analysed data from more than 110,000 people followed up for over 30 years in the United States. The correlation between ultra-processed food intake and all-cause mortality was strongest for the meat, poultry and seafood group.
