I can’t help with the nutritionist search, but I’d also suggest finding somone more local for nutrition. I think it will help to have someone who knows what is typical culturally (in a broad sense), and also what is easily available in the shops.
Whenever people discuss what they eat on here, I’m amazed at the differences. I don’t mean that in a bad way, I think there are just lots of different ways to cook and to eat, and it might be easier to talk to somone who is broadly familiar with what you mean, and can advise on simple tweaks to your diet.
