I strongly recommend you reconsider your planned diet. I don't know of an ethical case to restrict eating to fruits (or raw food for that matter).

To be honest, it isn't really a good idea to pursue raw veganism or fruitatarianism. This is outside the scope of veganism which is an moral belief about animal rights and standing up against the exploitation of animals. That said You can find a list of fruit trees that grow in the Amazon on wikipedia

The fact is though that South America and the Amazon is part of the modern world and they grow all the types of fruit trees there and are a big agricultural exporter of all kinds of fruits around the world. Not just the Amazon but Central America too. Everything from papayas which are native to bananas which are native to SE Asia.

Humans have evolved to eat cooked starches and a starch based diet with fruits and raw vegetables as a seasonal compliment to this. What this looks like is a diet rich in whole grains, beans, and vegetables with lots of salad and of course fruit as well. The only things we don't need to be eating are animal products and refined foods like white sugar and oil.

There's a great agroforestry community in Ecuador (Lumicon) that has a list on their website of over 200 plants that they grow.

Many of them are fruit trees, and it also includes many natural and native species to the region, which is in Napo provence – that's the Ecuadorian Amazon Jungle.

They're also a frugivorous vegan community, so you may want to check them out :)

I like fruit but I wouldn't want to just restrict myself to that stuff.
