A wealth of information can be found here for diabetics. In addition to all the information there are worksheets that you can use to fill in keep track of medications taken, blood sugar test results, etc. A very helpful thing I found was it provided a drawing of a hand and shows but drawing on your hand how much a portion size is (3 oz is the palm of your hand, 1 tablespoon is the size of your thumb, 1 teaspoon is the size of your index finger, etc) Great information here and very useful even for non-diabetics.
