Love that spicy rush with your sushi? Here’s the truth:
Most of what you’ve been eating isn’t real wasabi. It’s usually just horseradish, mustard, and green dye. But authentic Wasabia japonica — the true Japanese root — packs some legit health perks thanks to powerful compounds called isothiocyanates (ITCs).

🧬 Top 3 Health Benefits of Real Wasabi

1️⃣ May Protect Against Food Poisoning
Wasabi’s natural ITCs can fight bacteria like E. coli and Staphylococcus aureus. That’s why it’s traditionally paired with raw fish — to keep your gut safe (though it’s no excuse to skip food safety!).

2️⃣ Boosts Memory
A recent Japanese study found older adults taking wasabi supplements improved both short- and long-term memory. The antioxidants in wasabi may help protect the brain as we age.

3️⃣ Supports Cancer Defense
Like other cruciferous veggies, wasabi contains ITCs that may help prevent the formation of harmful compounds during high-heat cooking — and reduce cancer risk.

🍣 Real vs. Fake Wasabi — How to Tell

• Taste: Real wasabi has a quick, clean heat that fades fast. Fake wasabi burns and lingers.

• Texture: Authentic wasabi feels gritty, freshly grated — not creamy or pasty.
