People who can bit into an apple, either because they have natural teeth or dentures, are less likely to develop dementia. I never imagined that difficulty chewing would reduce blood flow to the brain.
Can you bite into an apple? If so, you are more likely to maintain mental abilities, according to new research from Karolinska Institutet in Sweden.
Research indicates several possible contributors to these changes, with several studies demonstrating an association between not having teeth and loss of cognitive function and a higher risk of dementia. One reason for this could be that few or no teeth makes chewing difficult, which leads to a reduction in the blood flow to the brain.
... those who had difficulty chewing hard food such as apples had a significantly higher risk of developing cognitive impairments.
