The greatest gain in longevity — 9.35 years — and health span — 9.46 years — came with the combination of an addition of 42 to 103 minutes of exercise and sleeping between seven and eight hours a day, while also eating an extremely healthy diet that included fish, whole grains, vegetables, and fruits.
The study, published Wednesday in the journal eClinicalMedicine, looked at almost 60,000 participants from England, Scotland and Wales in the UK Biobank, a longitudinal health study, who were followed for an average of eight years. Everyone in the study provided information on their diet — including ultraprocessed foods, such as sugar-sweetened beverages. A subset of the group also wore wrist watches that provided more objective measurements of movement and sleep.
