Switzerland probably
I'd also say Thailand but the milk will suck
Thailand is good for the fruits and fruit shakes etc.
You can get organic milk there now.
But in general Thailand isn´t that good. Most of the meals are fried in lots and lots of vegetable oil. There are some places where they use coconut oil for cooking, but they are rare.
For meat it is also mostly chicken (high in pufa).
So fruits would be good, and white rice. Other products are hard to get, and / or are more expensive (organic dairy for example, lamb/Beef etc.)
