French wife struggling with food (help)

Hi guys. Moved back to DC with my wife from France. She’s the best. She’s not fussy or a fussy eater. But one thing is the food here makes her really sick.

She’s started to develop acid reflux, she usually eats cheese or dairy no problem but the dairy here makes her violently ill. The bread makes her sick as well. She’s gotten bloated and extreme gastritis. She had to go to hospital once. We talked to a friend who is also from Europe and she had the same issue and it’s been ongoing for her for some years.

We are really struggling and she is an absolute trooper.

But does anyone know where we can get really really good organic groceries? I’ll pay anything, any cost for her to be able to just eat without sickness or pain. I’m pretty much fine but I grew up in the US. I did feel way better in France and lost a bunch of weight despite eating way more. But idk maybe it’s the pesticides or chemicals. I will pay any price for the most clean and premium groceries we can buy, we’re out in bethesda but I’ll travel, or pay delivery.
