I love the idea of baking breads using natural yeasts. The authors are pretty clear on the benefits of using natural yeast, giving many health reasons why a person would want to do this. And there are many reasons!I'm looking forward to trying the recipes, just as soon as I can get a start of natural yeast. The recipes look very good and pretty easy to make. It does take more time than using the yeasts you buy at the grocery store, but I am more than willing to take that time for the health benefits.Only one complaint - and it's not really a complaint, just sort of. The authors are consistent in calling it "natural yeast" - they are actually talking about sour dough starters, and I wonder why they don't just call it that. I understand that different yeasts have different flavors, from mild to quite sour, but using the term "sour dough" would seem to help people get the idea of what they are talking about much faster. Oh well - nothing is perfect. I definitely suggest that people try this book and use the recipes contained in it. Yes, they are a little more time consuming to make, but it seems a small price to pay for using the natural or sour dough starter that will help diabetics be able to eat bread - or that will eat the gluten in the bread before baking so that people with gluten issues might be able to eat bread again. Definitely recommend it for people who are interested in healthy baking and eating!
