Another January produce item that you don’t hear too much about are leeks. What is a leek? Leeks are part of the allium family which are related to onions and garlic, but are much larger and they have hairs for roots versus a bulb. Leeks are a great source of Vitamin A (important for eye health) and K (important for bone health), and being only 54 calories per leek, they are a great option when adding to dishes. Leeks are natural diuretics which means they help increase the amount of sodium and water being expelled from your body to preserve kidney function, and to prevent accumulation of toxins and salts.
