Fiber is indigestible and not required for human health. It's also a cause of bloating, constipation and gas... because it's indigestible. Fiber does have the benefit of slowing sugar digestion, but you can and should just eat less sugar. Some forms of fiber can be converted to fatty acids by bacteria in your colon, while also producing other byproducts. You can get those fatty acids by eating more meat without the added stress on your digestive system.
Compare the human digestive system of a human being to a wolf (carnivore), a pig (omnivore) and a gorilla (herbivorous hindgut fermenter). The human gut by proportions sits somewhere between wolf and pig.
Look up the actual studies on fiber rather than pop science articles, and examine them critically. They'll do things like assume that pooping more often and having a greater volume of poop is healthier, with no basis. Things like how easy it is to poop or feelings of being bloated are harder to quantify, so they're typically ignored.
Or you get the extrapolating cancer risk based on some vaguely understood biomarker, which is one step below "in mice" as far as science goes.
My theory is that the only reason we need indigestible carbohydrate is to push out the indigestible carbohydrate that is already stuck in the colon. Therefore we need it either all the time or not at all. Does this make sense?
My LDL numbers beg to differ.
Please expand on this. Cholesterol is a useful biomarker, but lower cholesterol could be worse. Cholesterol is used to repair the body. If your cholesterol is lower because you've inhibited your ability to produce it (malnutrition or by taking statins), that's bad. If your cholesterol is lower because your inflammation is lower and fewer repairs are needed, that's good. There are also two forms of LDL, one is harmless and the other is oxidized.
If you're feeling good, looking healthy and your body does what you need it to then I'd have to agree that whatever you're doing is working for you, numbers or theory be damned.
I know people are big on the whole fiber fad, but the bulk of benefits which come from eating more fiber are from eating fewer calories. If you're eating high fiber you physically cannot shovel as many calories into your belly. It is a viable strategy since most americans eat way too much every day, but fiber simply isn't essential to health or weight loss. If you like, explain to me a theory on why fiber is somehow essential.
