Among all the science fiction authors only H. G. Wells, as I recall, came close to the simple assumption: no evil alien race, no “intellects vast and cool and unsympathetic” will ever colonize Earth as no alien is prepared to our planetary micro- and macro-biological microcosm. We can speculate that the opposite is also true: we will never land on any other inhabited planet without poisoning ourself with their flora and fauna, which will be deadly for us. It is really surprising that humanity is spending a lot of money to get into this exact situation… on the Mother Earth. No wonder it will have the devastating effects on our health, even if we do not fully succeed in alienating from the microcosm of the planet.
Canadian research project SyMBIOTA has examined the data from comprehensive Canadian Healthy Infant Longitudinal Development (CHILD) archive to determine statistically and semantically important links between the use of household disinfection and gut microbiota of the infant residents. Furthermore researches used the data set to find the correlation of Body Mass Index (BMI) and the disinfectant and clearing products, Canadian Medical Association Journal reports.
It was discovered that disinfection has been altering gut microbiota of the infants. The reason is predictable as antibacterial cleaning products have different potency against different species of gut flora. No, there is no need to actually digest cleaning product to shift the balance in gut flora as gut flora in infants is based on what they get from the exterior. Could exterior flora be altered so will be gut microbiota of resident toddlers.
As a result of intensive disinfection levels of Haemophilus and Clostridium got lowered while Lachnospiraceae has flourished. By yet not determined mechanisms that probably led to changes in the digestion tract of the babies and eventually led to higher BMI. The link is clear and the data set is sufficient.
The other important result of the study is proving that ‘eco-friendly’ cleaning products are not scam after all. Households where eco-friendly products were used perform significantly better, with microbiota in balance and the BMI of toddlers are registered at statistically observable lower level.
This research, while scientifically insufficient may be very useful. There is no need to go to war with the own planet by unleashing chlorine, acids and bases on the surrounding under the disguise of keeping things clean ‘for babies’. It is important that toddler will get accommodated to surrounding flora and fauna. It is important to supply the new human being with the right, balanced starter kit of bacteria and not to intervene in this balance roughly.
