What foods cause flares? (for those of you affected by what you eat)

I know some people have dramatic responses to what they eat, and some not at all.

I myself have mostly moderate reactions that build up if I eat a lot of the specific food. Some of mine are odd. I'm just curious what bugs others!

I flare if I eat:

coconut milk

avocado

liquid cow milk

real butter

sour cream (but I can eat hard cheeses just fine)

black tea (though I can drink green)

cuts of pork like pork chops, pork loin (but not bacon)

I'm sure i'm forgetting something.

I've had several allergy scratch tests, and blood work done by a naturopath, and none of these showed up! So I'm not "allergic", just something about these foods causes my PsA and P to flare.

I have never found food played any parts in my flares. I flare terribly with colds or other infections and with wicked weather changes. Other than that the rest seems very random to me.

Sugar and wheat products

Milk

and night shades, especially white potatoes and green peppers
