Clarification for ground up oats

[Grizzly]

I just spent some time going through the numerous posts on grinding up your oats in a blender or coffee grinder and one point was brought up but was not really settled - raising it's GI. If it does indeed increase, is it minimal? I don't think it would really matter much, just wanted to see what the pros thought. I would be eating the ground up oats + whey and water around 10ish on my break at work, so it's not a pre-workout meal at all. Thanks guys.

It does raise the GI somewhat by grinding it up. It all depends on if you can stomach non-ground oats. I can drink them either way myself.

I don't think it's a significant amount in any case.

Not sure if you ran across my post on this subject, but here is a quote from me:

I have asked several experts about the GI of blended oatmeal. But it has not been tested yet, so I could not give you an exact answer.

However, all of them said that from their experience on how cooking a food effects GI, it should not be to large. For example, Ricky Mendoza stated, "There would be some difference in the GI if oatmeal were prepared in a different way. Based on other foods, however, I don't think that it would be a big difference."

Thanks guys, that's just what I was looking for.

Believe me - ground oats work SO much better in a shake that I for one am willing to live with a small GI increase if there is one. /forum/images/graemlins/smile.gif And I've said it before, but in my experience a coffee grinder does a much better job than a blender or food processor at grinding. It does it fast too.

I have said before I feel the GI is really overrated. The difference betweena a medium and low GI food that are 'healthy whole foods' is extremely minimal and here is why:

1) No studies have correlated insulin sensativty to eating a 'low GI' diet. Insulin sensativity is best correlated w/ fat mass.

2) Secondly, weight training improves insulin sensativty so we are better off in this category then the general population

3) When you eat as often as we do you wont *really* have swings in blood sugar b/c gastric emptying will almost never be totally complete between meals.

4) finally, and most importantly, a few studies have shown the GI HAS NO CORRELATION to the actual insulin response of a mixed meal. The GI is taken based on just eating a carb source on a near empty stomach but who actually does this? The true insulin response of mixed meals was found to be better correlated to fat and protein content of the meal. We all know how we like our EFA's and Protein so we are good to go on that front.


Basically, the GI is good because it will generally show you which foods are whole foods(as processing raises GI) but it isnt something I would live my life by. A few points on the GI will make zero difference to your body.

Oats are good for you period, grind them if you must. Aslong as you are eating it w/ protein it will not be a real problem.

Nice post, dunno.

Well said dunno!
And, when you consider GL (Glycemic Load - the effect from a normal portion of the food), GI is definitely overated. (And, if one measured GL of the meal....)
