Interesting Facts About Pumpkin Seeds

There are numerous benefits in consuming pumpkin seeds. We can get pumpkin seeds at a snack aisle easily, however according to Judith Wylie-Rosett, a professor from New York’s Albert Einstein College of Medicine, pumpkin seeds are lower in sodium and contain more of the minerals when they are organic and unprocessed.1 Pumpkin seeds have long been valued as a good source of zinc, magnesium and tryptophan. Here are the functions and benefits of each nutrient:


  • Boost our immune system as it is necessary for immune cell function and cell signaling. A review of seven studies demonstrated that 80-92mg per day could reduce the length of common cold by up to 33%.2
  • Accelerates wound healing. Zinc is commonly used for the treatment of burns, certain ulcers and some skin injuries. It promotes collagen synthesis, immune function and inflammatory response.2


  • Supports hundreds of chemical reactions in our body, which includes converting food into energy, creating new proteins from amino acids, genetic maintenance, muscle movements and nervous system regulation. 
  • Magnesium can help to move sugar from blood into muscles and dispose of lactate, that is why it is popular among athletes.


  • Is an amino acid that can promote sleep. 
  • 1 gram  of trytophan daily is shown to be able to improve sleep. That is equivalent to about 200 grams of pumpkin seeds a day.3
  • The zinc in these seeds can also help convert tryptophan to serotonin, which is then changed into melatonin, a hormone that regulates your sleep cycle. 4
