Greater than 47,000 died throughout the follow-up interval of greater than 30 years.
The crew discovered that greater PHDI scores had been related to a 15% decrease danger of dying from most cancers or coronary heart illnesses, a 20% decrease danger of dying from neurodegenerative illnesses, and a 50% decrease danger of dying from respiratory illnesses.
Ms Bui stated the PHDI could have to be tailored for various international locations, relying on their tradition or faith.
She additionally cautioned these with particular well being circumstances or meals accessibility points could discover a planet-friendly weight loss plan tougher.
