*Missing Nutrients : You may encounter problems with pumpkin seeds when some of their beneficial nutrients are destroyed by cooking, or when you don't chew the seeds and pass them whole. If you cook the seeds until they are crispy, you may be sacrificing the more unstable, water-soluble nutrients they contain, such as thiamin, riboflavin, niacin, and vitamins B6, B12 and C. If you pass the seeds whole because you didn't chew them, you'll miss out on all of the nutrients. You may think you're getting lots of nutrients when you are not. So carefully chew the seeds, and gently cook over a low heat.
*May Only Cure Symptoms : Another problem can arise when pumpkin seeds help cure the symptoms of a health problem but don't deal with the underlying cause. For instance, an enlarged prostate or prostate cancer can make it difficult to urinate. Pumpkin seeds can reduce inflammation and help with urination. But the seeds don't help cure the cancer or the enlarged prostate.
* Avoid when you have singles or cold Cold sores (Herpes) : Pumpkin seeds are a rich source of [[Arginine]].
