Answer: While horseradish fits the keto diet in moderation, there are other toppings that can add spice to your food without adding carbs.
Horseradish is a polarizing vegetable. Some enjoy its spicy punch, while others find it too bitter and overwhelming.
Each serving of horseradish (1 tablespoon) contains 1.2 g of net carbs. That means that you can still fit it into your meals, though it's not the most keto-friendly condiment you can find.
Horseradish 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 horseradish are less likely to develop lung or colon cancer.
Relative to foods like nuts and leafy greens, horseradish 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 horseradish 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.
