Personally I mostly look for not processed low FODMAP foods.
Coconut oil for cooking, crude olive oil as condiment.
Meat and fish for HQ proteins.
Mostly avoid legumes except for green beans and peanut butter (cause it's high on proteins and I fucking love it) 😂
Honey instead of sugar.
No integrations.
Me and my GF try to make what we can at home like bread (even if we don't eat lots of flours), marmalades 100% fruits, almond milk, peanut butter and other stuff.
We go local when we can.
And I only drink water!
