Horseradish, a root vegetable known for its sinus-clearing kick, offers more than just flavour—it also boasts significant health benefits, including fighting inflammation, bacterial and fungal infections, and potentially cancer. According to the Cleveland Clinic, the spice contains sinigrin, a compound also found in broccoli and cauliflower, which can disrupt inflammation and may help combat atherosclerosis, a hardening of the arteries.
Additionally, horseradish is rich in isothiocyanates, compounds shown to have anti-tumour properties. Dietitian Amanda Igel explained that plants in the Brassicaceae family, such as horseradish, contain compounds capable of disrupting cancer cells either by killing them, slowing their multiplication, or stopping their growth altogether. Cruciferous vegetables have also been linked to a lower risk of dying from cardiovascular disease.
The antibacterial effects of horseradish are noteworthy as well. Isothiocyanates can combat common foodborne pathogens like E. coli, H. pylori, and Salmonella, which cause symptoms such as nausea, vomiting, fever, and diarrhoea. While its antifungal properties are promising, further research is needed to fully understand them, according to Igel.
Historically used by ancient Egyptians and Greeks, horseradish provides vitamin C and essential minerals, including potassium, which helps regulate blood pressure. However, due to its intense flavour, only a small amount—such as a teaspoon—is needed to enjoy its benefits. It can be added to roast beef, burgers, mashed potatoes, garlic dips, or Bloody Mary drinks, and can be substituted for ginger in recipes for a different zing.
Those with digestive conditions like Crohn's disease, esophagitis, inflammatory bowel disease, ulcerative colitis, or stomach ulcers should exercise caution. Igel advises that horseradish can be consumed daily as long as it doesn't cause irritation; if stinging occurs in the mouth, nose, stomach, or throat, it's best to take a break.
