Sounds like those in moderation are good for you.

If you are more vegetarian, you can add soy and beans as well.
Beans are high in magnesium and protein.

It is refined sugar and white carbs, gluten bread etc which should be avoided as much as possible.

I agree. I can no longer eat sugar, flour, rice, potatos... any of the complex starches. I eat fruits, but solid/pulpy ones rather than juicy ones. Most (see below) veggies are fine. I've also found that, despite being Dx'd as non-diabetic idiopathic, my body/PN still responds as if I were diabetic, so I avoid all sugar sweets (including honey) and even sugar alcohols, found in many "sugar-free" and "diabetic" foods/treats. It makes finding chocolate I can eat a real bear.

There's also a possibility that some fruits/vegetables could still be triggers for you. I have to watch nightshades; they exacerbate my symptoms.

Trial & error should help you identify them. Keep a diary of what you eat/drink. If a flare occurs, review what you've eaten/drunk over the past 24-72 hours (some triggers can be delayed). I also have triggers I can get away with once (a week or month) but any more than that and they cause a flare.

The fun never stops.
