Wasabi might provide a memory boost

For those who love sushi, here’s something to remember: Japanese wasabi might boost short- and long-term memory in older adults.

We all know the sushi condiment from the often-pungent blast that punches the nose more than our taste buds. Wasabi cultivation dates to the eighth century. But it only became better known in the United States after 1980 with the rising popularity of sushi.

We already know from work in the laboratory that wasabi might improve cognition. Yet, studies were few and improved intellectual capabilities had not been tested in older adults. So, Japanese researchers recently took a closer look.

They recruited 72 people ages 60 to 80 and separated them into two equal groups. One group took a 100-milligram wasabi tablet every day for three months. The second group got a placebo.

Afterward, the cognition of volunteers was measured, including language and reasoning skills, concentration and memory.

Scientists discovered that the wasabi group’s long- and short-term memory improved significantly compared with the control group. They found no effect in other cognitive functions.

More testing is being done to explore wasabi’s benefits. Physicians aren’t writing wasabi prescriptions just yet.

The spice is also known for being rich in vitamin C and has antibacterial and anti-inflammatory properties. Indeed, researchers say wasabi might reduce inflammation in the area of the brain responsible for memory.

It’s important to remember that diet and exercise also play an important part in keeping our minds sharp. There is no single elixir for good brain health.

In the meantime, a sushi lunch just might hit the spot.
