A new study from Japan’s Tohoku University suggests that the spicy green topping could boost both short- and long-term memory.
While the team of researchers knew that wasabi was linked to a wealth of health benefits — such as antibiotic, anti-cancer and anti-inflammatory properties — they were “surprised” to see the “dramatic change” in participants’ cognition.
“The improvement was really substantial,” study author Rui Nouchi, an associate professor at the university’s Institute of Development, Aging and Cancer, told CBS News.
Researchers observed 72 healthy adults over the age of 60 who were either randomly given a placebo or a supplement containing 6-MSITC, a bioactive compound in wasabi that has brain-boosting anti-inflammatory and antioxidant properties.
“These functions are important for increasing cognitive functions in older adults,” the study authors wrote.he study, published in the journal Nutrients, compared the cognitive performance of participants — such as “executive function, episodic memory, processing speed, working memory and attention” — before and after the experiment, which lasted 12 weeks.
While no improvement was seen in other areas of cognition, the group scored approximately 14% higher in brain function than the placebo group.
Researchers believe the wasabi extract lowered the levels of oxidants and inflammation in the hippocampus, the part of the brain responsible for memory.
But if you can’t handle the heat, other foods have previously been shown to have memory-boosting powers: Red wine, certain teas, dark chocolate, banes, cherries or blackberries, to name just a few.
This is because they contain flavanols — a compound that is linked to better short-term memory, according to a study published this year.
The research observed the memories of more than 3,500 participants, who consumed either a placebo or 500 mg flavanol supplement every day for three years. Those who rarely consumed flavanols before the experiment and began taking the supplements saw an improvement in memory function in as little as one year.
A recent study conducted by researchers at Tohoku University in Japan has unveiled a surprising benefit of the spicy green topping, wasabi - it may boost both short- and long-term memory. While the team of researchers initially knew about the numerous health benefits associated with wasabi, including its antibiotic, anti-cancer, and anti-inflammatory properties, they were astonished by the "dramatic change" in participants' cognition.
The study involved the observation of 72 healthy individuals aged 60 and above. These participants were randomly given either a placebo or a supplement containing 6-MSITC, a bioactive compound found in wasabi renowned for its brain-boosting anti-inflammatory and antioxidant properties. The researchers found that the cognitive performance of individuals who consumed the wasabi supplement significantly improved in certain brain functions such as executive function, episodic memory, processing speed, working memory, and attention. These functions are especially crucial for enhancing cognitive abilities in older adults.
Over the course of the 12-week experiment, the group that consumed the wasabi supplement scored approximately 14% higher in brain function compared to the placebo group. The study authors hypothesize that the wasabi extract may have reduced levels of oxidants and inflammation in the hippocampus, the region of the brain responsible for memory.
Although wasabi appears to have promising cognitive benefits, individuals who cannot handle the spiciness need not worry. There are other foods that have previously been shown to possess memory-boosting properties. For example, red wine, certain teas, dark chocolate, bananas, cherries, and blackberries have all been linked to improved short-term memory. These foods contain compounds known as flavanols, which have been shown in a recent study to enhance short-term memory. The study observed the memories of over 3,500 participants who consumed either a placebo or a 500 mg flavanol supplement daily for three years. Individuals who had infrequently consumed flavanols before the experiment and began taking the supplements experienced improvements in memory function in as little as one year.
In conclusion, the recent study conducted by Tohoku University in Japan has shed light on the surprising memory-boosting properties of wasabi. By consuming a supplement containing a bioactive compound found in wasabi, individuals exhibited significant improvements in brain function. However, for those who prefer less spicy options, there are other foods such as red wine, tea, dark chocolate, bananas, cherries, and blackberries that have also been linked to improved memory. These foods contain flavanols, which have been associated with enhanced short-term memory. Further research may shed more light on the potential of these foods and their compounds in improving cognitive function in individuals of all ages.
