I eat an anti-inflammatory diet for psoriasis, so it is a bit more strict than a basic one. Basically, I eat super clean all week long with 1 meal on the weekend of my choice. I usually will crush a pizza with a dark beer, pancakes and sausage, bacon cheeseburger or something along those lines. i usually feel like I'm having an orgasm when I eat those "cheat" meals.
However, for the rest of my week I eat literally nothing but:
-Chicken (baked or grilled)
-Amaranth and other pseudo grains
-Steel cut oats
-Olive oil only
The big thing in my diet that I stay away from are...
-No vegetable/soy oils, canola oil, peanut oil, etc.
-No processed foods.
-No bread, no pasta.
-No red meats. Not even pork.
-No white potatoes.
-No whey/casein protein products. I found these actually flare my shit up.
Amaranth has been a life saver for me (as a lifter) for a quality carb source. I literally eat 1 pound every day. I cook a big pot in the morning and store it in pyrex dishes and eat it several times a day. Another thing I do is juice with a cold press juicer every single morning.
I will usually juice:
3 cups spinach
1 orange or some fresh pineapple if I have one
For me, I try to keep my omega 3 ratio as high as possible, as I found when I consume foods dominant in certain types of omega-6s it can cause flare ups (inflammation). Everything I consume during the week comes from whole food organic sources (with the exception of my chicken, I can't afford organic chicken in the amounts that I eat) and I cook/make everything myself. It can be a huge pain in the ass and when I first stated doing this it was sort of depressing but I have grown to actually like it because I feel so much better. I didn't realize how shitty certain foods were making me feel.
I'm sure you don't have an auto-immune issue like I do, so you might not need to be as strict, but hope this helps some. Also, to be perfectly honest, if I didn't have psoriasis, I would probably still be eating fast food, pizza and mexican food every day.
