Researchers at Tempe University’s Lewis Katz School of Medicine say adding extra virgin olive oil to the diet may be an effective way to reduce the risk of dementia in older adults,media reported. Because extra virgin olive oil has many known health benefits, such as its potential protective effect on the brain, it is often referred to as a “superfood.”
The new study from Tempe University involves mice. According to the researchers, the mice’s diet was characterized by extra virgin olive oil, and the mice were 30 to 40 years old. After six months , when the mice were about 60 years old , the researchers found that the tau deposits in the mice dropped by about 60 percent .
Tau is a protein associated with the formation of various types of dementia. The problem involves tau deposits, which accumulate in the brain and cause cognitive decline. The most common form of dementia caused by tau deposits is called eclampsia;
According to the study, mice on a diet fed extra virgin olive oil performed better on learning and memory tests than mice that were not fed “superfoods.” This is likely to be the result of a healthier synapses in the brain, the researchers said.
Although the study involved mice, its protective effects may also be applicable to humans. The researchers plan to explore the potential effects of extra virgin olive oil on older mice that have already suffered tau damage, especially whether olive oil can help treat health conditions. The researchers also recommend that people who plan to add extra virgin olive oil should choose products that are certified as genuine.
