The article describes how researchers used first-of-a-kind "smart pill" sensor capsule to measure precise temp and gas (in this case, CO2) before and after intake of chemical or food agent. It provides factual, in vivo scientific foundation and mechanism to things people may have "known" for a long time. It's a scientific approach to prove or disprove what the people think they know.
..... "Our experiments with pigs and cinnamon show how swallowable gas sensor capsules can help provide new physiological information that will improve our understanding of diet or medicine... They are a highly reliable device for monitoring and diagnosing gastrointestinal disorders." < snip > ..... This work is part of a bigger study into gut health using swallowable gas sensor capsules or smart pills. ..... "The capsule is swallowable but indigestible, which has enabled real-time and precise gas measurements in different sections of the gastrointestinal tract in animal models." ..... < snip >
