What is the most common food in brazil?

"Food in Brazil revolved around three key things, 1) arroz which is white rice, 2) feijao which are black beans and 3) farinha which is like flour. It is very hard to try and avoid eating these although they do come in different shapes and sizes. These are usually eaten with either red meat, chicken or fish."
