Pull back the attitude just a little there. You are correct that insulin is more than just spikes and something that makes you fat and is not as simple as it may be played out to be.
Eating any type of food leads to a rise in insulin (better sounding than a spike?) when blood glucose levels rise. Carbohydrates alone have a higher increase than other macros.
Blood glucose levels rise the most with high amounts of simple sugars, thus a higher amount of insulin needed to reduce levels. When glucose has been shuttled to needed areas of the body (brain, muscle and liver glycogen, etc) and there is an abundance it definitely gets stored. I don't think anyone was stating that eating any type of carb makes you fat.
Are you saying that the type of food doesn't matter? (just trying to see exactly what you are saying).
