I've been searching unsuccessfulky for a clearer answer to what constitutes an insulin spike. For example, if my fasting bg is 90, then I drink a protein shake and it goes up to 102; is that just normal or a spike? I'm testing losts of foods-beverages to determine if they are problems, but with the exception of foods with sugar or starch, it isn't clear to me if my readings mean any given food is giving me too much of an increase.

The question is a little unclear as an insulin spike is not the same as a blood sugar spike. There are some foods which cause an insulin spike, but have a lesser effect on blood sugar.

See this study for the insulin index of a selection of different foods:

See this post by Dr. William Davis on the Heart Scan blog about post meal blood sugars..

I realized after doing several searches yesterday that this use of "insulin spike" as synonymous for a BG spike is the problem. Even though they sort of go hand in glove. Someone directed me to this site which gave me the information I was looking for: http://www.phlaunt.com/diabetes/16422495.php

I'm still not sure when I should consider a food a problem that does not raise my bg to extreme numbers, but does give a reaction. I guess it's something I have to play by ear.

I was testing myself randomly 20 minutes after some meals (it probably should be 45). I figure if it goes to 145, that's too much. So I've cut out full servings of whole wheat (suprise) breads and cereals and potatoes.

What kind of "reaction" do you have rather than rising bg numbers?

there is no such a thing as an "insulin spike".The insulin concentration in blood increases after meals and gradually returns to basal levels during the next 1-2 hours. However, the basal insulin level is not stable. It oscillates with a regular period of 3-6 min. After a meal the amplitude of these oscillations increases but the periodicity remains constant. [1] The oscillations are believed to be important for insulin sensitivity by preventing downregulation of insulin receptors in target cells

The Definitive Guide to Insulin, Blood Sugar & Type 2 Diabetes (and you’ll understand it)
I think it's worth everyone's time/energy to spend a few days with a blood glucose meter and some test strips to check what is your base blood glucose level and what happens after breakfast lunch and dinner. I know this means going through a lot of strips but unless you invest the time you won't understand how your body reacts to certain basic foods such as milk or wheat.

I think we should also remember that we are measuring spikes in blood glucose and it is these high blood glucose levels that require the pancreas to work harder to produce the insulin required to deal with excess blood glucose.

Milk and|or wheat are not basic foodstuffs to some of us!

Although I must admit, I would be quite interested to see my blood's reaction to the meat and eggs that I eat.
