I agree its a chicken vs egg situation....does exposure to healthy bacteria lead one to seek healthy foods, or does exposure to healthy foods inherently promote the growth of healthy bacteria?
Such questions are at the hearts crux of this long standing conundrum, where rational science is seemingly willfully ignorant of the spiritual and energetic nature of what makes for a healthy balance, within all biological systems. Foods that are pure and unadulterated will feed the growth of life promoting microbes...but even catabolic microbes which dissolve and decay have a necessary place in maintaining the balance. The synergy of the entirety of lifes symbiosis, cannot be parsed into bits of linear data. False dichotomy between good and bad bacteria does not hold up to the newer discoveries which go beyond the limitations of the defunct Germ Theory of disease hypothesis.
The presences of different strains of bacteria that are prebiotically cultivated in the gut are not the cause in and of themselves of the conditions of health or disease...instead they are more like a symptomatic indication of the holistic synergy...The modern day Priest of the white coat clans, are only beginning to uncover the pervasive interrelationships between the almighty microbes and its human subjects. There is still much room for misunderstanding and misinterpretation of the data...this is in part due to a deeply and hopelessly ingrained pathos, that these natural and spiritual elements which promote health and vitality, within living symbiotic systems, can somehow be isolated, extracted, patented and then sold as a cure all to people whose own environments are in want of healthy conditions.
