Is there a diet thats best for treating psoriasis?”
all kinds of miracle cures being touted. Suggest you first visit the psoriasis page here: http://www.psoriasis.org/treatment/psoriasis/diet/ Also, sometimes psoriasis is related to Celiac Disease, where the digestive system is unable to process gluten. That needs to be checked. Other than that, there is no diet cure for psoriasis, although you may find personally that certain foods tend to aggravate or relieve it a bit. Because it is YOUR immune system and individual to YOU, you are going to have to be the one to look for clues in your diet. You might want to work with a dietician on this. See if your doctor can recommend one in your area who has some experience in this area.
