Patrick Holford ,the wonderful man who founded "The Institute of Optimum Nutrition" has written some books on low glycaemic load diets.
A diet like this can control bloodsugar balance.This way of eating has helped people prevent diabetes,and those who already have diabetes have been able to reduce their medications or come off them altogether.

He also talks about chromium, cinnamon and various herbs,spices and foods found to reduce blood sugar.
Most importantly it lists the glycaemic load of hundreds of foods to give you an idea of what amounts of foods you should eat and what foods can be combined to stabilise blood sugar for longer...

for example an apple with a handfull of seeds or nuts is a great snack.
Also you will learn things like 10 raisins have the same effect on your blood sugar as one whole punnet of strawberries..
with this knowledge you can make food choices that will help
you regain control of your health.

Look him up.It will change your life in a positive way,
I promise.
