More and more people have dementia, a decline in cognitive function common in older adults. Researchers continue to search for natural ways to prevent this condition. Researchers at Tohoku University in Japan suggested that eating citrus fruits, such as oranges, grapefruits, lemons or limes, every day could help lower the risk of dementia by nearly 15 percent.
Previous studies have reported that citrus fruits are in flavonoids, which can cross the blood-brain barrier and contribute to antioxidant and anti-inflammatory activities. In turn, this could reverse and repair some forms of cellular damage. One cross-sectional study reported that high consumption of citrus is positively associated with better cognitive function.
The Tohoku University team aimed to further examine the association of citrus fruit intake with the incidence of dementia. To do this, they carried out a statistical analysis using data from the Ohsaki Cohort 2006 Study, which involved Japanese people aged 65 years and older in 2006. Researchers gathered data on the participants’ frequency of citrus intake through a survey. Then, they followed up with 13,373 respondents in 2012 to determine how many participants in the cohort developed dementia within six years.
The researchers asked in the survey questions about the participants’ dietary and lifestyle habits. They categorized responses related to citrus consumption into three: those consuming citrus twice or less in a week, three to four times per week, and almost every day.
The findings of the study, which were published in the British Journal of Nutrition, revealed that those who ate citrus fruits more frequently had a lower risk of dementia. The results were the same even after the researchers considered other factors that may be related to dementia, including psychological distress, motor functions, and cognitive functions.
In addition to preserving cognitive function, citrus fruits offer many other health benefits. Here are some of them:
