As the satisfied owner of the product featured in the book, I am thankful for the often delicious recipes that Mr. Kordich included in this book. However, I don't believe a word of the psuedoscience behind his dietary maxims. Kordich describes juice combinations that will restore one's pancreas, liver or skin. I think that certified nutritionists would find these allegations questionable. Kordich instructs the juicing public not to mix fruit and vegetable juice (with a few exceptions) and to not mix melon juice with other fruits (like they would produce toxic gas or explode). The best advice is to use the juice as a tasty supplement to ensure decent nutrition, follow the recipes in "Power of Juicing," and read the rest for a laugh.
