‘There are 7 million Lebanese-Brazilians today’ is the result of your own two minute searches on Google. Actually this sentence comes from Wikipedia. 

What must have escaped your attention is that the Brazilian government claims there are only 4 million Brazilians of Syrian descent, actually mostly Lebanese as Lebanon at the time of immigration was still part of Syria. Even this number is inflated because it includes people who have one grand-parent originating from Lebanon-Syria. https://en.wikipedia.org/wiki/Arab_Brazilians#Statistics

Wiki reports that ‘São Paulo, Rio Grande do Sul, Mato Grosso and Distrito Federal, 0.9% of white Brazilian respondents said they had family origins in the Middle East.’ About 92 million Brazilians described themselves as White; which gives about one million Brazilians of ME origin.
