You may not think much of it when you're biting into something hard, but your chewing ability could tell a lot about your cognitive function.
According to research out of the Karolinska Institutet, chewing ability was linked to a reduced risk of dementia. The study's authors suggest that there are several possible contributors to changing in cognitive ability, and losing one's teeth may correlate with a higher risk of developing dementia.
The study reports one of the possible reasons for this phenomenon could be because having no teeth can make chewing difficult, which leads to a reduced blood flow to the brain. The researchers looked at 557 people who were at least 77 years old.
The study's authors found that people, regardless of sex, age, education and mental health problems, who had a difficult time chewing an apple had a higher risk of cognitive impairment.
The researchers also noted that whether the chewing was done by dentures or natural teeth had no effect on the outcome of the study.
