2. Resistant Starchess
All plants contain starches, whether "simple" like sugars, "complex" as in low glycemic index food, or "resistant." It is difficult to find fruits and veggies that have naturally occurring resistant starches but they can be produced at home and there is even a flour called "Hi-Maize" which you can buy at Amazon.
There are several advantages to consuming resistant starches. As the name implies, they are resistant to breakdown in the upper gastrointestinal tract and essentially arrive in the small intestine intact where they act as probiotics. The good bacteria in our guts use these starches as a source of fuel and metabolic products of this action include beneficial acids such as butyric acid.
They are also good for diabetics and pre-diabetics since they don't elevate blood sugar levels. And they act as a natural fiber, so much so that some scientists consider resistant starches as another type of fiber, besides soluble and insoluble.
That's it for now. I will write about what to eat and what to avoid in another post.
