Huh??? I have been to Recife in the state of Pernambuco, Brasil where there are a lot of Caju trees. The “Pernambucanos” eat the raw pseudo-fruit and drink the juice of the “Caju” all the time. The actual fruit is the part that is roasted to make cashew nuts, and below that there is a succulent pseudo-fruit which can be eaten raw and juiced. In fact the caju pseudo-fruit has a higher level of Vitamin C than the acerola, and a heck of a lot more than the orange. There is a whole lot of information
here. Although I guess you could be correct when it comes to the nut, since the cite above has this to say:
But the pseudo-fruit can be eaten raw, and is absolutely delicious!!!
