Endive is a leafy green from the chicory plant family that is high in nutrients. It''''s used in a variety of foods, most notably salads. It has a sturdy texture and a tangy, buttery flavour when roasted, grilled, or braised. Endive is abundant in potassium, fibre, and folate, all of which are beneficial to heart health. Potassium is a well-known blood pressure-lowering substance. Urination helps relieve blood vessel strain and counteracts the effects of elevated salt levels in the blood.
