Wasabi is a spicy vegetable that you're mostly likely to find as a topping for sushi. It's a close relative of horseradish, which is why some regions refer to it as "Japanese horseradish."

Each serving of wasabi (1 tablespoon) contains 2 g of net carbs. That's a bit on the high side for a condiment, but you can fit in small amounts if you've got a strong hankering for wasabi.

Consider limiting yourself to half a portion per day to avoid going over your carb limits.

Wasabi is a good source of fats, at 0.5 g per serving. The keto diet is all about fats, so any time you can find a high-fat food you enjoy, consider it a win.

Vitamins and nutrients

Wasabi is a cruciferous vegetable, a family of crop species that includes kale and broccoli. Scientists are interested in cruciferous vegetables because of evidence that suggests that they contain compounds that prevent cancer. More research is needed, but several studies have found that people who consume cruciferous vegetables like wasabi are less likely to develop lung or colon cancer.

Relative to foods like nuts and leafy greens, wasabi is low in nutrients. Enjoy it in moderation, but don't let your indulgence push out other, healthier carbs.


If you're a bit of a heat seeker and want a replacement for wasabi that's more keto-friendly, consider Frank's RedHot Sauce. It adds a spicy kick to your food, and it's a zero-carb option.
