Laura,
There is nothing wrong with the avocado. I like them very much, to make some guacemole or a nice salad. Only I read in the Sinclair book that they are high in starch and she advised to leave them out of the diet. Should you be doing the diet and eating avocado's without any negative results: go on but be careful.
