Fiber is one of the best-studied ingredients in our diet. It is also by far the most health-giving ingredient.
As described in the book, fiber shows a strong correlation with significant reduction in all-cause-mortality (and linked to that a significant reduction in the risk of suffering from a range of big diseases (e.g., cardiovascular, cancer). (i) What makes the case that this is not just a spurious correlation and likely a causation, is that the effect is concentration dependent. In other words the more fiber we eat the higher the positive impact.
At a recent fruit industry conference that I attended, I was stunned by how much attention phytonutrients such as polyphenols are getting and how fiber is just a passing thought. Why is it that no one sees the elephant in the room?
The answer in my mind is simple: Specific polyphenols (e.g., grapeseed polyphenols) can and are patented, whereas fiber is much harder to patent as it appears that most fibers have about the same level and range of benefits
(i) There are many meta-analyses on the benefits of fiber, here are just two: Impact on all-cause mortality: Veronese N, Solmi M, Caruso MG, Giannelli G, Osella AR, Evangelou E, Maggi S, Fontana L, Stubbs B, Tzoulaki I. Dietary fiber and health outcomes: an umbrella review of systematic reviews and meta-analyses. Am J Clin Nutr. 2018 Mar 1;107(3):436-444; Impact on Cardiovascular disease: McRae MP. Dietary Fiber Is Beneficial for the Prevention of Cardiovascular Disease: An Umbrella Review of Meta-analyses. J Chiropr Med. 2017;16(4):289-299.
I really enjoyed this take on fiber the way you explain its hidden benefits makes something we all overlook suddenly interesting and actually worth paying attention to. I was reading it during a hectic study week, and honestly, there were moments I joked I need someone could do my online finance class just to free up a bit of headspace and really absorb helpful posts like this without feeling rushed.
I enjoyed reading your post about why fiber often gets overlooked even though it’s such an important part of a healthy diet, especially how it affects digestion, blood sugar, cholesterol, and overall gut health. When I had a big week of classes last term, I even had to pay someone to complete my computer course work so I could catch up on assignments and still eat better, and that taught me how small choices add up. Your article made me think about how easy it is to miss simple nutrients like fiber despite how good they are for our bodies.
I read the post about why fiber seems to be lurking in the shadows and it was interesting how fiber, one of the most studied parts of our diet, is still not talked about as much as other “trendy” nutrients even though it links to many health benefits like lower risk of big diseases and better gut health. I remember a crazy finals week when I was so stressed that I had to pay someone to do my MBA exam while trying to eat right and take care of myself. Thinking back, it taught me that balance in life and knowing what really matters, like good health and steady effort, makes a big difference in how we handle hard times.
