An advocate of Food Combining since early 2001, I found health and weight loss my reward by my summer holiday. Unfortunately, the colder weather of autumn led me from the straight and narrow to stews, burgers and other unhealthy combinations. In my search for re-inspiration I discovered this title by Jan Dries and hoped it would not only persuade me to begin combining again but also clear up the indistinct areas from other F-C titles eg should sugars really be considered as a starch and how do I distinguish starch & acid fruits? As a Biology grad I was particularly looking forward to such an up-to-date scientific review of a controversial theory.
The theory started well by further clarifying protein, starch and neutral food groups into protein, starch, acids, fat & sugar, but after two long weeks of ploughing through the first two sections of this book I still didn't know how to combine them. The 'easy to use' pentagrams determining which of the 10 possible pairings of these groups are allowed, either had arrows missing (p45) or were showing 7 'bad' combinations and 3 'good' instead of the 6 & 4 proclaimed twice in the text (eg p130). On turning to the in-depth chart on p131 displayed like a football fixture chart ie each team shown along the top and also along the side, I was perplexed to find that the combinations didn't match up. That is, there were two different results for the same combinations (like an away & home result to follow the football theme). I would expect that reading tomato & potatoes in one direction would be the same as the other but in fact one says that's it's a good combination and the other that it's bad. A bit of advice if you use this table, after cross-checking all results and matching it with the text, it seems safe to discount everything above the diagonal line and instead use the information below.
As I'm sure you've sensed my frustration with the editing deficiencies of the book, it's long-winded nature and often contradictory views, I'll finish by saying it's not all bad. The section on 'How digestion works' is excellent, by the end of the book you discover that you aren't restricted to eating bad combinations (eg protein and starch) a strict number of hours apart - in fact, as by most nutritionists, eating little and often is advocated, and the 'football' chart is very useful if you annotate it and stick to the relevant part.
Overall, I have found the book informative - the categorisation is sensible, the science is interesting and the recipes are tasty. My main recommendation is not to start at page 1 and work through as I did but read according to interest and dip in and out. However, be warned that if you are easily frustrated, new to food combining or irritated by editing errors then it may be better to read 'Food Combining for Health' by Doris Grant et al in the short term or perhaps to wait for the next (and hopefully more accurate) revision of this weighty tome.
