Someone told me that and I was skeptical, and now you confirm it. I thought, since I keep tasting the fruit after I eat it, that the acidity remains, and it's better therefore to brush it away. Toothpaste is supposed to be good for you!
I actually find this topic more interesting and meriting further investigation, rather than the original topic of the article! I rarely brush my teeth and then eat (that would defeat the purpose, no?) so the original topic kinda left me scratching my head, since I don't have much experience of that.
btw, relevant comment, that one ^
:P
