In the north, the food is simple, clean and healthy; a normal dinner consists of fresh fish and perhaps some chicken, rice, beans, farofa, and a simple salad. Fresh fruit is excellent breakfast usually includes a lot of fruit, as well as eggs, toast, and “tapioca”, which are crepes made from manioc flour.
Any negatives? There does tend to be a lack of green fresh veg is the north, especially compared to California. That said, the food is fresh and delicious (just not that green :)
If you stop in Rio or São Paulo you will find a very highly evolved Brazilian cuisine with all sorts of world-class restaurants, as well as many international offerings.
