As a medical student who has been closely reviewing probiotic research, I would like everyone to know that research is extremely important.
Perhaps it will be the greatest breakthrough in medicine of the 21st century. This angle is one of the primary reasons that the ‘calories in=calories out’ theory doesn’t function as a successful principle for people trying to lose weight and keep it off. I recommend looking into the GAPS diet for anyone suffering auto-immune problems, since auto-immune disorders are all primarily caused by dysregulation of the digestive system.
Some ideas on the yogurt study (also being an opportunity to explain some of the nuances):
there is an incredible breadth of biodiversity in the gut, and yogurt only typically contains one or two strains, in this case it looks like one.
gut bacteria number in the trillions, so a short-term regime of any probiotic food or supplement won’t necessarily provide its benefits quickly. A significant amount of the benefit is also delivered in the chelating and detoxifying properties of healthy bacteria, which can over time remove harmful toxins built up in intestinal bile; a significant build-up may take years to fully flush though, and other health problems may still still inhibit it.
other things in the diet will impact bacterial growth just as much as the addition of yogurt. Foods high in sugar could very easily be inhibiting the multiplication of the yogurt’s probiotic bacteria (after being ingested) by encouraging the growth of competing bacteria associated with negative health. Food eaten then also becomes the basis for the bacteria’s food, so a poor quality diet could sabotage the probiotics.
the quality of the yogurt which the probiotic was added to will impact the growth of bacteria tremendously. The pasteurization process itself makes the yogurt less healthful and can create an environment less conducive to probiotic multiplication.
no distinction is made whether the stress can be considered ‘justified’ or not; it would be undesireable to be less stressful in a situation where stress is justified and helpful. The study also seems not to account for variance in difficulty of course load, since students may have signed up for classes with intuitive knowledge of the additional stress received through their usual gut bacteria.
there are also a variety of standard practices in preventing contamination, which I assume the group carried out
