Supposedly, the FDA has banned sulfite use with fresh fruits? Hm. Best wishes for narrowing down the culprit.

I'd also have your car's exhaust checked to make sure you're not getting some carbon monoxide inside. Or is the a.m. the only time you're in the car and get a headache?

Wow, good catch, Olychick! Great that you thought of that possibility.

Switch to fresh fruit and see if you still have headaches. I generally eat blueberries every morning, but lately I've been eating blackberries and raspberries because they were on sale. I only buy fresh fruit, although I do have fruit in the freezer that I froze myself. The stores always seem to have some fresh fruit that I like to have with my yogurt and granola, but if they didn't, I would add dried fruit instead of frozen. Not sure if dried fruit has anything added, but I would expect the package to tell me.

I hope you find the cause of your headaches and get to feeling better. Let us know.

I think dried fruit is more likely to have sulfites than frozen. It won't be long till the pick-your-own blueberry farms are open for business. I want to head out that way with my grandson and get some then. They are zoo good. Fresh berries here at the store are expensive and questionable in freshness. I've learned to open the plastic boxes to see if they have started to mold. Sadly, usually, they have.

My coworker thought of the exhaust problem, but it's not every time I drive, so it's probably not that. It would be a good idea to check that out, though, just to be sure.

Don't know if you're eating organic frozen, but if not, maybe try a bag and see if there's pesticide or something else that you're sensitive to on the non-organic. They are on the list for the most contaminated at this site:

Yeah, I haven't been eating organic. Organic frozen fruit is out of my budget.
