     I am not really much of a diet fan, my weight has never been an issue. I eat whatever I want, when I

want. But as Pamela McDonald explains diet is not merely a method for controlling weight, but has a

significant influence on health and quality of life.

     I can hardly imagine that living on fried bacon would be a good way to lose weight and promote good

overall health. Likewise a steady diet of cabbage soup would likely become somewhat monotonous(单调乏味的) after a couple of days.

     Pamela McDonald takes a different approach, there is no one-size-fits-all diet, different people need

different things. Although all humans are intrinsically(本质地) composed of the same material, the building blocks, our genes, are subtlety different.

     The author maintains that one particular part of a person's DNA, something called the APO E gene,

has much to do with how our body tolerates foods of different types. This gene comes in 8 varieties and

depending on the variety the food requirements are different. This has little to do with weight loss, and has more to do with overall good health. Weight gain is not a 'problem' but rather a symptom. A diet alone

will not resolve the entire problem, it is merely one part of the larger picture.

     I have to admit that parts of The APO E Gene Diet were a little heavy going, I appreciate that the

author felt the requirement to back up her claims with some scientific data, but for the lay(外行的) man

it makes for some rather difficult reading.

     The second half of the book, is recipes, now this is something I do understand! She has created some

very innovative dishes, and certainly more than one that had me feeling hungry just reading them. My

favorite of them is a very traditional English dish the Cornish Pasty.

     An interesting book and one that people should read, you can get your copy from Amazon.
