Arugula
Arugula is a cruciferous leafy green vegetable rich in glucosinolates and vitamin K, commonly eaten raw in salads or cooked. It contains compounds that may influence detoxification pathways and bone health.

Arugula (Eruca vesicaria) is a cruciferous vegetable native to the Mediterranean region, now widely cultivated globally. It is commonly consumed raw in salads, used as a garnish, or lightly cooked in pasta dishes and stir-fries. The plant's peppery flavor comes from glucosinolates—sulfur-containing compounds characteristic of the Brassica family. One cup of raw arugula (approximately 20g) provides approximately 5 calories, 0.5g protein, 0.7g carbohydrate, and negligible fat.
Arugula is a source of vitamin K, folate, vitamin C, and dietary fiber. It also contains glucosinolates, which are metabolized by gut bacteria and the liver into isothiocyanates and other bioactive compounds. The fiber content supports normal digestive transit and colonic microbiota. Arugula contains oxalates; individuals with kidney disease or a history of kidney stones may wish to monitor total dietary oxalate intake, though a typical salad portion poses minimal risk for most people.
Bone Health and Vitamin K
Arugula contains vitamin K1 (phylloquinone), a cofactor required for carboxylation of osteocalcin and matrix Gla protein—proteins involved in bone mineralization and vascular health. Adequate vitamin K intake is associated with higher bone mineral density in observational studies. One cup of raw arugula (approximately 20g) provides roughly 21–22 micrograms of vitamin K1, contributing meaningfully toward the adequate intake (AI) for adults (90 mcg/day for women; 120 mcg/day for men). Larger portions or multiple servings accumulate intake significantly.
Tolerance and Portion Guidance
Arugula is well-tolerated by most people in typical serving sizes (1–2 cups raw per meal). The glucosinolates are not toxic and are converted to potentially bioactive metabolites during digestion. Individuals taking warfarin or other vitamin K-dependent anticoagulants should maintain consistent vitamin K intake and discuss any significant dietary changes with their healthcare provider, as fluctuations in vitamin K consumption can affect anticoagulant efficacy. People with thyroid conditions generally need not restrict arugula; evidence suggests that goitrogenic compounds in raw cruciferous vegetables are substantially reduced by cooking and are unlikely to be clinically significant at typical serving sizes for people with normal thyroid function. Those with irritable bowel syndrome or sensitivity to sulfur compounds may experience bloating or gas with large quantities.
Frequently Asked Questions
Does arugula interact with warfarin?
Arugula contains vitamin K1, which affects the same clotting pathway that warfarin modulates. People taking warfarin should maintain consistent intake of vitamin K-rich foods and inform their healthcare provider of significant dietary changes. Eating arugula in normal amounts is not contraindicated, but sudden large increases or decreases in consumption may affect anticoagulant efficacy and should be discussed with a pharmacist or physician.
Is arugula high in oxalates?
Arugula contains oxalates, though its oxalate content is lower than high-oxalate vegetables such as spinach or beet greens. Typical salad portions are not a concern for most healthy people. Those with a history of kidney stones or kidney disease should monitor total dietary oxalate and discuss arugula consumption with their healthcare provider.
Can arugula upset digestion or cause gas?
Arugula contains glucosinolates and fiber, which are fermented by gut bacteria and can produce gas or bloating in some individuals, particularly those with irritable bowel syndrome or sensitivity to sulfur-containing vegetables. Cooking arugula and eating smaller portions may reduce these effects. Most people tolerate arugula well in normal serving sizes.
