Findings from a new study in mice suggest that obesity and poor nutrition can cause damage to accumulate in blood vessels, reducing oxygen supply to parts of the brain. This will ultimately cause cognitive decline. It is estimated that approximately 42% of American adults are obese.
In the study, scientists uncovered the mechanisms underlying the link between midlife obesity and increased risk of cognitive decline and dementia in later life.
An experiment on mice showed that those on a high-fat diet showed increased cellular aging and decreased density of healthy blood vessels in the brain after three months. They also performed worse in the maze test than normal-weight mice fed the standard diet.
