Describe the properties of soluble fiber.

Question

Accepted Answer

Hello everyone. Our next question says which of the following is not a property of soluble fibers. A soluble fibers are a type of dietary fiber found in oats, Barley and Psyllium B. Solid soluble fibers can increase the sensation of fullness and aid in weight gain. C soluble fibers help to reduce blood cholesterol and glucose levels. Or d soluble fibers form a viscous gel which slows down digestion. So it's pretty easy to remember from the name soluble that soluble fibers are ones that dissolve in water or aqueous solutions. And when they dissolve, they form a viscous gel. So choice D that first part is true. So the viscous gels form to wind soluble fibers dissolve. And as you can imagine, this viscous gel moving through the system slows down digestion. So choice D is a property of soluble fibers. So cross that out. Now, if we slow down digestion, what are some effect that the effects this has? Well as you're digesting food. If the food has a lot of carbohydrates in it, your blood glucose levels will go up. But if the whole process is slowed down, those glucose levels are prevented from spiking because the absorption of glucose is slowed down. So, soluble fibers do help to reduce glucose levels due to digestion, slowing down. And they also do help reduce blood cholesterol. And this is because that gel substance actually traps cholesterol, preventing it from being reabsorbed into the bloodstream. And once it's trapped, it actually gets ex excreted along with the stool. And so instead of being reabsorbed, entering the bloodstream, raising blood cholesterol, it's getting removed from the body. So choice C also a property of soluble fibers. So let's look at choice A are there is soluble fiber found in oats, barley and Bayi. Yes, it is. And in addition, also found in apples, citrus fruits, beans and carrots. So that is true and not our answer. Therefore, so by elimination, we have choice B is our correct answer. But we also could have arrived at this by logic. So soluble fibers can increase the sensation of fullness. Well, yes, that is true because again, you have this thick gel moving more slowly through the system. So it does make you feel more full, but feeling more full is not going to aid in gaining weight. Instead, it will aid in weight loss or weight management. So just by logic, presumably, we could have arrived at that looking at that's choice B. But again, the one that is not a property of soluble fibers is choice B that they increase the sensation of fullness. True and aid in weight gain that is the incorrect part. See you in the next video.
