I make most of my decisions about what to eat or not eat based on glucose readings after a meal. Oatmeal, even steel cut oats, makes my blood sugar rise.
Because the fiber in oats is soluble, it can supposedly lower cholesterol. Here's a quote from an about.com website....http://cholesterol.about.com/od/cholesterolnutrition101/f/howfiberworks.htm
Quote:Soluble fiber lowers cholesterol by binding to it in the small intestine. Once inside the small intestine, the fiber attaches to the cholesterol particles, preventing them from entering your bloodstream and traveling to other parts of the body. Instead, cholesterol will exit the body through the feces.
Soluble fiber appears to be only effective against your LDL cholesterol, so if you also need to lower your triglycerides, or boost your HDL, soluble fiber may not be able to help you with this since the effect can range from very slight to no benefit at all. Additionally, you should not solely rely on fiber to lower your cholesterol, since the effect is only slight (LDL cholesterol can decrease by at most 18%).
That is not the only problem with trying to lower cholesterol with oatmeal though for anyone who is either prediabetic, diabetic or insulin resistant. While the soluble fiber in oatmeal will in fact prevent some it from entering your bloodstream, it also can cause a blood sugar/glucagon imbalance because of the carbs.
The key to controlling cholesterol levels seems to be having the correct insulin and glucagon levels from what I have read. (I highly recommend the book "Protein Power" and their chapter entitled "Cholesterol Madness" for a better explanation).
Since oatmeal causes a blood sugar/insulin problem, the fact that it binds with cholesterol in our diet and carries some of it out of the body does little good if the body then compensates by making more cholesterol because our blood sugar/insulin is out of whack.
So yes, the soluble fiber does carry some cholesterol out of the body, but it is meaningless if the food itself causes an insulin/glucagon imbalance that just causes the body to start making and producing cholesterol like crazy.
The end result is the body makes a lot more cholesterol than the fiber carries out. For some people who are not diabetic or insulin resistant, steel cut oats might help but for those of us with blood sugar problems, the carbs more than negate the positive effect of the soluble fiber.
Since you don't crave oatmeal (which I don't blame you since I don't even particularly like the taste much less crave it myself), as a diabetic, I do believe you would be better off eating something a lot tastier with a lot less carbs.
Again, (I highly recommend the book "Protein Power" and their chapter entitled "Cholesterol Madness" for a better explanation). You might have to read the chapter a couple of times as it gets a little technical, but it is well worth the price of the book and a worthwhile read (imo).
