| Hi Glucolog: Welcome. You should definitely have your family member(s) join the forum and ask all kinds of questions...it's a big help, especially when you're first trying to deal with a new diagnosis, and a continued help on a day-to-day basis.
For me, I found a great deal of information in Dr. Bernstein's Diabetic Solution..had a great deal of info the physiologic aspect of it. If they are T2, I've heard other mention a book by Gretchen Becker, but I've not read it yet. As far as websites go, for nutritional info, there's dietfacts.com, which gives national chain restaurants menus and all nutritional information, which is so helpful to check before going out for carb counts, etc.
All the reading material is great, but support from other diabetics is, IMHO, what has given me the most encouragment and inspiration to do what needs to be done to properly manage diabetes. |
