The fruits I rely on daily are bananas, blueberries, dates, pineapples and apples. I wish  I could splurge on mangos and papayas, but they are hard to find ripe. It would be a feast, if I lived near the tropics. Montreal is not fruit heaven...
I buy stacks of frozen bluebberies and pineapples as it is hard to find them ripe  and they are very instrumental to my daily well-being.

For the fats I eats lots of avaocados, hemp, flax seeds., sesame /tahini.

Grains: buckwheat, teff, millet

Squashes are in season :D 

Leafy greens: lettuce, spinach, arugola

The moringa power has been a super healing and nutritional addition in the past 2 years.

I also eat fermented foods, like kimchi and saurkraut and kombucha. It seems like I'm making progress as I have been able to eat miso without side effects. I wish I could eat kelp to get an abundance of good bacteria, but I'm not there yet. 

I doubt Japanese people suffer from gastro-intestinal diseases.....!

Celiac disease is a common disease in Italy, pasta land. :) Entire aisles in supermarkets have been dedicated to gluten-free products already in the past 15 years....
