After combing through the whole of Borders in a futile attempt to locate this book and getting the staff to help ("healthiest foods" has no matches; however we do have a few matches on "healthy foods"), I was forced to conclude that the only way to get it is by ordering from amazon.
And now it's finally here! =) Looking forward to poring through it and learning some good (read: simple and healthy) recipes over the weekend.
Here is the book @ amazon: the world's healthiest foods
and here is the link of the book's website: http://whfoods.org/
