I found this book today and looked up diabetes mellitus in the index. Here's what I found:
Avoid refined white sugar. Use natural sugars such as maple syrup, honey, dates, and molasses sparingly. Use stevia or agave to sweeten your food and drinks. These sweeteners actually balance the pancreas and have very few calories. Take chromium picolinate and trace minerals to help balance the pancreas and reduce sweet cravings.
Gymnema sylvestre, a wonderful herb from India, lowers high blood sugar levels and greatly reduces excessive secretion of glucose in the urine. It also increases beta cells that produce insulin, and may reduce the need for insulin treatments. Recent studies have shown that cinnamon can actually balance blood sugar levels as well. Fenugreek seeds were used in ancient Italy, Greece, and India to treat blood sugar disturbances in the body. Fenugreek seeds can help reduce insulin requirements by lowering blood glucose levels. Soak fenugreek seeds, sprout them, and put them in salads and on soups. The high fiber content delays glucose absorption.

I'm an educator, a relative to someone who has type 1 diabetes, and an individual with an eagerness to absorb as much information as I possibly can about type 1 diabetes in order to pass on that knowledge to others.
