Digesting Pollens: Can We Benefit from Supplements?

AI Thread Summary
Pollen grains are marketed as food supplements, but their digestibility is a concern due to the presence of sporopollenin, which is largely indigestible. While some believe pollen is nutritious, the regulatory environment for dietary supplements in the U.S. allows products to be marketed without proving their safety or efficacy. This raises skepticism about the actual benefits of pollen supplements. Digestibility can be improved through methods like extensive chewing or blending, which can rupture the grains and release nutrients. The concept of bioavailability is crucial, as it varies with factors such as age and digestive health, affecting how well nutrients are absorbed. Pollen's resistance to digestion is significant in palynology, where fossilized pollen provides valuable climate data. Overall, while pollen can offer nutrients if processed correctly, its effectiveness as a supplement remains debated.

They say that Pollen grains are used as food supplements.
But the sporopollenin is practically indigestible. So then how are these pollens grains digested in our intestines?
Are they processed before consumption?

Who says?
 
I meant there are food supplements of pollen grains
It's there in our textbooks and in stores :-)

Huh. I had no idea. :biggrin:
 
At least in the US, most dietary supplements are basically unregulated:
  • Federal law does not require dietary supplements to be proven safe to FDA's satisfaction before they are marketed.
  • For most claims made in the labeling of dietary supplements, the law does not require the manufacturer or seller to prove to FDA's satisfaction that the claim is accurate or truthful before it appears on the product.
(http://www.fda.gov/ForConsumers/ConsumerUpdates/ucm050803.htm)

So, just because some people use it as a dietary supplement does not mean that it is actually doing anything.
 
I don't know if that was suppose to answer my question.
We were taught that pollens are highly nutritious and hence used as supplements.
 
I can barely find anything on google, as I have to wade through a million webpages extolling the virtues of bee pollen as a miraculous superfood. Which makes me seriously suspect about any benefits of pollen. Can I ask what textbook(s) you are using?
 
It's by the NCERT- it's the book by the central board of education for the whole country
+ modules my tutorials give
 
If you physically rupture pollen grains, then, yes, there are human digestible nutrients inside. For example, extensive chewing, a blender, or some cooking methods can do this more or less efficiently. I'm not in any way recommending the stuff.

In fact, there are a lot of small insects and other arthropods that feed only on pollen. The whole topic of being hard/easy to digest is called bioavailability, which you can read about now that you have the search term. This is a really interesting topic, BTW. Bioavailability of some nutrients changes with ageing in humans. Old guys like me secrete less stomach acid than young people. A plant with tiny lithocysts of calcium, say eaten raw, provides less calcium per unit volume for old folks versus young folks. There is less acid in the gut to help break down the lithocysts. And there is a disparity between the amount of calcium required in the diet, versus what your body actually needs and uses. I'm too lazy to get a reference with good numbers, but, the recommended daily value for calcium in the US diet is greater than the calcium actively untilized - for all ages. Because of bioavailbility.

Pollen is remarkably resistant. Palynology is based on the fact that the enzymes to break down pollen walls are not ubiquitous in nature. For example, lake bottoms have lovely, pretty much yearly varves made of pollen and sediment. These persist for very long periods of time. Fossil pollen from them is very important for getting information on local climate at the time of the deposition of the pollen.

Pollen and spores (the forerunners of modern Angiosperm pollen) can be old, as in Silurian age. See the picture of Silurian plant spores (modern plants were not around then).

Oh okay thanks a lot [emoji1]
So indigestible but not impossible to get through the exile. Okay [emoji4]
