The first one is available for all to read. It finds that "Participants with the highest quintile of dietary fiber intake had 23% (men) and 18% (women) lower mortality compared with the lowest quintile."
Fiber is good for you.
The second is not publicly available but can be found if you know how to use the website, sci-hub. It was "an inpatient crossover study in 17 adult over- weight or class I obese non-diabetic men. Participants were first fed a baseline diet (BD) for 4 weeks (50% CHO, 15% protein, 35% fat) followed by a 4-week KD (5% CHO, 15% protein, 80% fat)".

From "Why Bifidobacteria Are So Good for You" (https://www.healthline.com/nutrition/why-bifidobacteria-are-good)
One of the main functions of this type of bacteria in humans is to digest fiber and other complex carbs your body can’t digest on its own Fiber has been shown to help reduce weight gain and the risk of diabetes, heart disease and other chronic disorders. Bifidobacteria may help reduce the risk of these diseases by digesting fiber That’s because when they digest fiber, these beneficial bacteria produce important chemicals called short-chain fatty acids (SCFAs). These compounds play a number of important roles for gut health, and may also help control hunger Bifidobacteria help produce other important chemicals too, including B vitamins and healthy fatty acids They may also help prevent infections from other bacteria such as E. coli, in part by producing chemicals that prevent toxins from passing into the blood submitted by /u/cangetenough [link] [comments]
