Lifesaving food 90% aren’t eating enough of (bbc.com)

It is difficult to eat enough fiber. My trick is that I keep a sealed plastic container in the refrigerator with a mixture of cooked spiced beans. I usually just use black beans and garbonzo beans. I vary the spices, but usually use some combination hot spices. It is easy to then add these to whole wheat pita sandwiches, soups, salads, etc. This way I get a lot of fiber and extra protein.

clickbait title should be replaced by something like "90% of us aren’t eating enough fibre, and how to improve that"

Despite the title it has some good info

Sweet potato is a cheap and easy dietary fiber source. Also good slow burning source of energy. The betacarotene on it, in my opinion it is unclear it is good or bad for you. I think betacaroten daily maybe not good, maybe some varieties of sweet potato has less betacarotene Anyway is a good and cheap food, can keep you alive on frozen winter.

What about supplementation? Psyllium Husk comes to mind.

Wikipedia's article is very thorough https://en.wikipedia.org/wiki/Dietary_fiber#Fiber_contents_i...

and makes the distinction between soluble and insoluble fiber. Quick source: 100g of almonds has 12.5g d.f., as well as a wealth of important vitamins.
