Increased PHDI scores had been related to a 15 per cent decrease danger of loss of life from most cancers or cardiovascular illnesses, a 20 per cent decrease danger of loss of life from neurodegenerative illness, and a 50 per cent decrease danger of loss of life from respiratory illnesses.
Nonetheless, Bui cautioned that the PHDI doesn’t essentially replicate all meals gadgets and their relationships with all main illnesses in all nations, as it could fluctuate with particular well being situations, spiritual restrictions, or meals accessibility.
