India's love affair with fennel needs no introduction. The seed spice dominates a variety of our preparations. Did you know that India happens to be the largest exporter of fennel seeds, widely known as saunf. A common practice in most Indian households is to have few fennel seeds or saunf at the end of every meal. This practice you might think is to freshen the mouth, but think again. A concentrated source of minerals like Copper, Potassium, Calcium, Zinc, Manganese, Vitamin C, Iron, Selenium and Magnesium, the age old practice does much more than simply beat bad breath. From regulating blood pressure to water retention, fennel seeds pack a bevy of nutrients that make it a must have in your kitchen.
