Have you ever looked down at your hands and noticed funny white spots on your nails? Are the tips of your fingers rough with tiny blisters? Did you know that these are classic signs of having a zinc deficiency? Frequent colds, infections, lack of appetite, impaired taste, and even depression can also signify a zinc deficiency. Zinc is important because it helps to balance our blood sugar levels, stabilize our metabolic rate, and helps to keep our immune system strong. To increase your intake of zinc, try eating foods like pumpkin seeds, chard, spinach, asparagus, yogurt, collard greens, broccoli, and sesame seeds. They are great sources of zinc and they taste great!
