sample size n=37 of which recruitment only happened in Shanghai without any real control for confounders, only evaluated over a period of two weeks with no longterm follow-ups, the dosage of 40g RS/d is very high (would take about 4-5 large potatoes daily for equivalency or ingesting likely expensive supplement), the crossover compares RS vs CS in the same participants with only a 4 week washout which is a weakness since fermentable fiber persists >4 weeks, also the supplement they used was industry-provided by a starch manufacturer which was weirdly not disclosed
this is a great study if you are an overweight/obese adult without overt metabolic disease, willing and able to consume 90 g/d of starch supplement within a controlled diet, and living in Shanghai with similar baseline fiber intakes endemic to that population. it is extremely not generalizeable to you or even me though I fit more of those characteristics than I care to admit
stay skeptical of small studies like this, friend
> not generalizable
But there's already a general advise on this: eat more fiber.

We're a great ape, our body evolved to process a lot of fiber from fruits and starches. It's the modern fiber-deficient diet that's really weird.
90g/day of fiber is similar to the Hadza tribe diet, where they can consume 100-150g of fiber per day.
Fiber’s the new fad supplement.
I hope you're not being serious, but they're not "supplements", they're food. You can easily get them from fruits and vegetables.
While they're not essential in short-term survival, they're essential for long-term health:

We have enough peer-reviewed studies on this.
it has been for a while, a lot of foods advertise fiber
I thought we were onto protein now?
Also, the authors claim the starch "inhibited lipid absorption." They do not argue why they used surrogate blood biomarkers instead of residual energy output in fecal samples (which is a better measurement).
sample size is 37, number of authors 29
