Here is a reconstruction of the report's key findings based on indirect evidence: gut bacteria ferment fiber into butyrate
Normally, gut bacteria ferment fiber into butyrate, acetate, and propionate. These SCFAs signal to the brain via the vagus nerve to promote sleep continuity. In GF subjects, SCFAs are zero. The brain, lacking this "stay asleep" signal, defaults to a primitive awake state. SCFAs are zero. The brain
