Hi Patricias,
Here I am! Glad I checked the boards today. Nice to meet you!
For sure you can have hidden intolerances, as well as needing time and some other factors.
For example I can't eat: carrots, bananas, citrus, nightshades or too much brown rice. I can eat nuts/seeds but if I have more than an ounce or two it can cause gut and joint pain. (Black rice is OK for some reason, but spendy so I don't eat it much)
As for starches I do best with winter squashes - acorn, butternut, pumpkin, delicata, spaghetti squash and my personal favorite, kabocha. I eat sweet potatoes but honestly if I have too much of them I do not feel great, so squashes it is.
Best beans/legumes FOR ME are red lentils and great northern beans, but I can't eat more than 1/2-1 cup a day or it is too much. Lots of beans don't work for me.
I find that the best way to eat for me is sort of and Eat To Live/MWL blend method with lots of raw and cooked green leafy and green veggies plus things like summer squash and cauliflower. Not too much beans and squashes as my starches and not too much fruit. (2-3 fruit/day)Plus lots of raw salads.
Overeating causes problems for me as well as not chewing my food.
I have also discovered that I do best if I follow a sort of modified
Fast-5 diet approach, eating within a 6 hour window. I guess my digestive system needs regular extended breaks.
It did take me a long time. PsA feels in some ways less immediately responsive to diet changes than say, RA, but I for me it did come eventually with 100% adherence and persistence and exploring some food intolerances was time went on. For example, for a long time I was eating bananas and carrots, and that could have extended my recovery time, or...it could just take a long time. I don't know.
My psoriasis did clear up right away so I knew I was on to something but the joint pain did take longer and will come back fast if I stray.
Hope this helps!

P.S. I also had PMS, PMDD, and depression. I find I need to eat SOME nuts and seeds to avoid depression but not too much as that worsens the PMS/PMDD. Before getting sick and changing my way of eating only VERY INTENSE exercise had any positive impact on PMS/PMDD (running hard 3-5 miles 5-6 days/week) and depression, but since changing my diet I find that a combo of regular moderate exercise (walking briskly every day for 30-60 minutes, light weights a couple times a week, stretching) helps and that acupuncture is also helpful. So, not all issues were resolved by the diet change I have done for 5 years now, but acupuncture is minimally invasive and very helpful. In case that information is helpful.
