There is a difference in grain products. You are correct in stating whole grains. The important point Kevin states is "refined carbs". These are unhealthy and cheap. Look at corn syrup and all the things it is used for. Look at the flours used in bread products.
Sticking to whole foods is good.
The refinement of whole foods to many of the products we eat/drink instead is unhealthy and has led to a great deal of the obesity problem we are facing.
Activity, or lack there of, is the other big factor.

No they don't. Overeating and being fat and sedentary causes most
cases of type 2 diabetes. As a diabetes specialist physician told me
recently: "Let's not mince words, these people are *fat*.

Grains have nothing to do with it. This is an enduring myth. Many
indigenous groups are susceptible to type 2 diabetes, probably
because their genetic makeup is sensitive to excess energy intake --
fat storage etc -- not because of grains. Interestingly, in the Pima
Indians, two different cultures exist: those living a more
traditional lifestyle in Mexico with a diet mostly vegetarian with
corn and squash and potatoes, and another group in Arizona who have
settled in to a western diet with a high consumption of fat and
refined sugars and starch. The Pima living a traditional agricultural
lifestyle in Mexico have dramatically lower incidence of diabetes on
a high grain and vegetable diet and plenty of hard work. Their fiber
intake is estimated at 50gms/day compared to 15 gms/day for the
Arizona Pima with western, high-fat diet and very high rates of
diabetes.

The story is essentially the same for the Navajo.
Intake of nutrients and food sources of nutrients among the Navajo:
findings from the Navajo Health and Nutrition Survey. Ballew C, White
LL, Strauss KF, Benson LJ, Mendlein JM, Mokdad AH. J Nutr. 1997
Oct;127(10 Suppl):2085S-
Regarding grains in general and type 2 diabetes risk, the evidence
seems to indicate that rather than causing diabetes, whole grains are
actually protective. See this study:
Whole grain, bran, and germ intake and risk of type 2 diabetes: a
prospective cohort study and systematic review. de Munter JS, Hu FB,
Spiegelman D, Franz M, van Dam RM. PLoS Med. 2007 Aug;4(8):e261.
"CONCLUSIONS: Whole grain intake is inversely associated with risk of
type 2 diabetes, and this association is stronger for bran than for
germ. Findings from prospective cohort studies consistently support
increasing whole grain consumption for the prevention of type 2
diabetes."
