Definitely follow the dietary advice in SWAMI. That diet will account for menopause plus whatever other health issues you have, continue to blend BTD and GTD just for you, etc.
The Menopause book is probably a good read, for some background information on how diet can help balance your hormones. It can also be fun to see which foods are reccomended to eat or avoid for menopause, and compare those to your SWAMI list. You may want to borrow a copy from the library and read it once, rather than purchasing a copy to keep. Since you won't need the food lists in there as a reference, it may not be worth spending the money on. (Unless you have the budget and the shelf space and want to build up a library of BTD books that you can refer to as needed and lend out to others.)
