'A new study shows that the traditional Japanese spice wasabi can improve some
types of cognitive function in those aged over 60, offering a straightforward
and rather tasty way of looking after our brains as we get older.
Key to the association is the wasabi ingredient 6 methylsulfinyl hexyl
isothiocyanate (6-MSITC), a bioactive compound that has previously been linked
to antioxidant and anti-inflammatory effects that slow down damage to cells and
protect them.
While a small number of studies have shown 6-MSITC having a beneficial effect
on cognition, this hasn't yet been tested with older adults – the people who
are most at risk of cognitive decline and related problems like dementia.
"Previous studies suggested that antioxidants and anti-inflammatories have an
important role in cognitive health in older adults," write the researchers in
their published paper. "Therefore, 6-MSITC is expected to have a positive
effect on cognitive performances in older adults."
The team ran a trial involving 72 adults aged over 60 across the course of 12
weeks. The participants were split randomly and unknowingly into two groups:
the first group took a wasabi tablet once a day, while the second group took a
placebo tablet.
At the end of the experiment, those who had ingested wasabi tablets showed
significantly better performance in their episodic memory (recalling events
from the past) and working memory (holding information temporarily) based on a
series of cognitive tests.
However, no significant differences were found in other areas of cognitive
performance, including reasoning, attention, and processing speed. The team
thinks the wasabi, and 6-MSITC, might be particularly affecting the hippocampus
part of the brain, which is particularly important for memory function.
"These findings suggest that the 12 weeks' 6-MSITC intake selectively enhances
working and episodic memory functions in healthy older adults," write the
researchers.'
