I hope this information is usefull to someone.
I've suffered from psoriasis for years. Tried all kinds of treatment. Nothing really worked. I would break out on my face legs and arms. After researching psoriasis i decided to try my own treatment. I Cut redmeat, alcohol (beer especailly) and most dairy out of my diet. Within 2 weeks, I stopped breaking out. THEN the creams started to help with the spots that were already there. My face and arms are completely healed (it's been a total of 4 months now). The two reallly bad spots I have on my legs are almost gone. Now if I eat a steak, within 2 days I break out. So now i'm just selective when I want to eat redmeat. Although it's been 4 months, i've had psoirasis for years, this is the closest i've come to having "normal" skin.
Hope this helps someone
