Wasabi, the fiery green condiment often enjoyed with sushi, may hold unexpected benefits for memory, according to a study published in the journal Nutrients. The research focused on 72 healthy participants aged 60 to 80, with half of them consuming 100 milligrams of wasabi extract at bedtime, while the others received a placebo. After three months, the group that consumed wasabi extract demonstrated significant improvements in working (short-term) memory and longer-lasting episodic memory, outperforming the placebo group in standardized assessments for language skills, concentration, and simple task execution. The active compound in wasabi acts as both an antioxidant and anti-inflammatory agent, providing protection to the brain and facilitating improved nerve signaling, which is believed to enhance memory. The study, while promising, underscores the need for further research on individuals with existing memory loss and a comparison with other anti-inflammatories like curcumin.
However, it’s essential to note that obtaining genuine wasabi can be a challenge outside of Japan, as many available products are imitations with only a small fraction of real wasabi. To ensure authenticity, consumers can request the wasabi to be freshly grated in front of them, as real wasabi is typically gritty and not smooth like its fake counterparts. For those who may not enjoy the taste of wasabi with food, supplements or incorporating 100% wasabi powder into various dishes can be alternatives. While the study suggests that wasabi may be a valuable addition to the toolkit for memory improvement, maintaining a plant-rich diet, regular exercise, optimal sleep, stress management, and the inclusion of other brain-boosting foods remain crucial elements in preserving memory function.
