Summary

How well do oat bran and green banana powder work as stool bulking agents and for related health benefits?

Participants report that both oat bran and green banana (especially as powder) improve bowel movements while also supporting cholesterol and blood glucose control. Green banana powder is praised for its resistant starch content and ease of use in shakes or oatmeal. One correction notes that the starch in banana powder is not the same as inulin despite earlier assumptions. Several users tried the powder but did not repurchase after finishing their supply.

The heading captures it. These foods support managing cholesterol, stabilize blood sugar including HbA1C, but the main benefit is much improved bowel movements.

Green banana powder really stands out even if not widely known. I enjoy adding a portion to my morning oats or a blended drink. The resistant starch is great.

Is green banana just a banana that hasn't ripened, or is it a particular variety?

Tried mixing some green banana powder into my protein drink each morning. It was okay but I didn't bother replacing it once finished.

Whenever I see that I imagine it spoken in a really nasal voice on purpose.

Banana powder works mainly because of its resistant starch called inulin.

Inulin and resistant starch aren't identical even if I used to believe that. Check out this discussion from a food scientist on gut health and fibers for the details. The whole exchange is informative.

Tried putting the green banana powder into my protein shake for some time, though it caused too much bloating in my stomach. Still thinking of using it for baking.

Cooking that thing ruins its value completely.

I promise on my life that you people really enjoy starting lousy forum topics.

Well, your reply finally drew a response from you. 😂 Every creature produces waste like that. Yet I once thought ladies never release gas because of a story my mom shared when I reached five. They simply keep it all inside instead. I can confirm that's the exact claim she made. Quite a bit of time passed before I grasped it wasn't true.

For a while now I've been adding underripe bananas to my meals aiming at possible upsides for intestinal microbes. Clearly there's no way to measure results in that area yet I've seen they ease my regularity issues.

Wow, it turns out those unripe bananas I've enjoyed for years actually offer health benefits, which is awesome!

Since this has few carbs there's no reason to toss it out.

It's disappointing how no pictures ever show up from them 😢
