Resistance Starch "The next hot nutritional trend "?

I was reading about this recently and honestly had never heard the term before in my life "Resistance starch"..... I personally try to eat a low carb diet and have trained my mind to hate carbs... but this is kind of interesting..so here it goes..

What are resistance starch ?
basically Resistant starch is bulky, so it takes up space in your digestive system. And because you can't digest or absorb it, the starch never enters your bloodstream. That means it bypasses the fate of most carbohydrates, A resistant starch is a starch that resists this enzymatic action and doesn’t break down into sugar molecules. which get socked away as body fat when you eat more than you can burn.

It ups your calorie burn: Unlike some types of fiber, resistant starch gets fermented, This can prevent the liver from using carbs as fuel and, instead, stored body fat and recently consumed fat are burned,"

It shuts down hunger hormones: A meal with resistant starch triggers a hormonal response to shut off hunger, so you eat less. Research shows that you don't reap this benefit from other sources of fiber.

Reduce calories: Foods containing a lot of resistant starches are somewhat lower in calories than other carbohydrates because at least some of the food energy stays locked up in the resistant starch and doesn’t get digested and absorbed.

I know most of you are probably on a high protein low carb diet, but when u do eat some carbs I say go for the resistance starch carbs.. Like: dried beans, bananas and mangos (especially under-ripe ones), and starchy foods like potatoes, rice, and pasta that have been cooked and then cooled. Something about the cooking and cooling process converts starches into resistant starches. So, for example, a cold pasta or potato salad will contain more resistant starch than freshly cooked pasta or a baked potato.
Doesn't give you a free ticket to eat carbs like crazy but at least when u do, you will be choosing foods that are naturally higher in resistant starches.
 
I'm skeptical. Cooling down potatoes doesn't stop it from converting into sugar. Fermented foods are great for you as long as they are pasteurized.


This is a great topic bring the studies and articles.

I'm also kind of skeptical... I found this on how cooling these foods chages the The physical and chemical composition of starch and whether starch is digested in the small intestine or whether it ferments in the colon. There are several reasons why starch may not be digested:

Some starch may be physically trapped inside intact plant cells as in wholegrain foods like muesli and grainy bread. This starch is therefore inaccessible because digestive amylases are unable to penetrate or break down the cellulose cell walls.
The higher the amylose content of starch the greater its resistance to digestion because they form tighly packed granules in cells. Raw potato, green bananas, pulses and high amylose maize starch have a high amylose content.
When starch is heated, starch granules swell and are disrupted. This process, known as gelatinisation, makes the starch much more accessible to digestive enzymes. Starch with a high amylose content and starch which is inaccessible due to the physical structure in which it is located, are less susceptible to gelatinisation and hence are more resistant to digestion.
When starch that has been heated, is cooled, retrogradation occurs converting some of the gelatinised starch to a crystalline form which is resistant to digestion. Foods, such as bread, cornflakes, cold cooked potato, rice and pasta, contain retrograded starch which is resistant to digestion.
