Potential Risks and Considerations
- High Vitamin K Content: While beneficial for most, those on anticoagulant medications (like warfarin) should moderate intake and discuss with their doctor.
- Allergy: Rare but possible for people sensitive to cruciferous vegetables.
- Goitrogens: Like other cruciferous vegetables, arugula contains goitrogens, which could interfere with thyroid function in individuals with known thyroid conditions when consumed in very large quantities.

- Smaller leaves are typically milder and more tender, suitable for raw dishes.
- Store dry, unwashed arugula in a sealed bag in the refrigerator vegetable drawer. Wash just before use to prevent spoilage.
