Wasabi intake before sleep improves memory in over 60s, groundbreaking study finds

A scientific team assessed the cognitive abilities of 72 healthy volunteers aged between 60 and 80. The participants were divided into two groups. One group consumed 0.004 ounces of wasabi extract before sleep, while the other group received a placebo. The trial lasted 12 weeks.

The researchers evaluated a series of cognitive abilities in participants, including executive functions, memory, processing speed, and attention, both before and after the study. Conclusively, those who had consumed wasabi showed better short and long-term memory regarding language skills, focus, and capacity to perform basic tasks.

Maintaining a regular eating schedule can significantly support brain function.

"We explored the potential benefits of consuming 6-MSITC, wasabi's bioactive compound, on cognitive health in older individuals. The study discovered that taking 0.00003 ounces of 6-MSITC for 12 weeks improved memory functionality, including episodic and working memory. However, we found no significant enhancement in other cognitive functions. Our study is the first to conclude that 6-MSITC positively affects memory function in healthy older individuals," the scientists reported in an article published in the 'Nutrients' journal.

Understanding 6-MSITC

The antioxidant and anti-inflammatory compound 6-MSITC is found in trace amounts in other plant products. However, this compound is predominantly found in wasabi. It reduces inflammation and oxidant levels in the hippocampus, the brain region responsible for memory.

Physicians advise close monitoring of high blood pressure symptoms as they can be visibly manifested on the face, a potential cry for help from a heart under stress.

Scientists theorize that consuming 6-MSITC could improve everyday memory function in aging populations. However, they need to test the wasabi impact across other demographic groups to determine if this spice can help delay memory deterioration associated with dementia.
