Skin

• Zinc aids in the development of healthy skin, and acne and psoriasis treatments often include zinc.
  
  

Fertility

• Sexually active men need more zinc than women do because there is zinc in semen. Zinc deficiencies can cause male infertility.
  
  

Immunity

• Zinc plays a big role in immune system functions and cell growth. One of the first signs of zinc deficiency is decreased immunity.
  
  

Cooking

• Spread raw pumpkin seeds on a baking sheet with some olive oil and a little seasoning to roast them for a snack. One serving of pumpkin seeds, or about a quarter cup, offers 20 percent of a typical adult's daily value of zinc.
  
  

Storage

• Store pumpkin seeds in an airtight container in a dry, cool area. For longer storage, use the refrigerator or even the freezer.
