The Mayo Clinic Cookbook was given to me as a gift from a friend who also loved it. The recipes have comprehensive nutrition analyses, and a color picture of every dish showing the individual portion size. This is very helpful, you can browse through and see what you're in the mood for. Their preparation times don't seem to correspond to a home kitchen, I wouldn't rely on them. The recipes are all very tasty, but I have found that the assortment of spices they use are very limited. They use black pepper to an extreme. I no longer use a recipe straight from the book without analysing the spices they suggest first. Changing the flavoring with different spices does not affect the nutritional value of the recipe, it just allows you to adapt the flavor to your individual palate. I have been able to control my blood pressure, reduce my blood cholesterol, lose weight, and save money, all by using this cookbook exclusively for three months. Try it. I'm back here to buy three more to give to friends this Christmas!
