The examine means that for each 10% enhance in each day consumption of ultra-processed meals, folks had a 25% increased danger of dementia.
The analysis additionally discovered that substituting simply 10% of ultra-processed meals with unprocessed or minimally processed meals, like contemporary fruit, greens, legumes, milk and meat, was related to a 19% decrease danger of dementia.
Researchers recognized 72,083 folks from the UK Biobank examine, a big database containing the well being data of half 1,000,000 folks.
