\nand Me was an amazing application of what researchers found to be true in
\nrodents and then applied to a human. It was like a reverse “Supersize Me, “using
\nprebiotics and a healthy diet to lose weight. The abstract reads:<\/p>\n\n
\nbetween obesity and gut microbiota in mice. To find out whether that link
\nextended to humans, microbiologist Zhao Liping adopted a regimen involving
\nChinese yam and bitter melon–fermented
\nprebiotic foods that are believed to change the growth of bacteria<\/b> in the
\ndigestive system–and monitored not just his weight loss but also the microbes
\nin his gut. When he combined these prebiotics with a diet based on whole
\ngrains, he lost 20 kilograms in 2 years. His blood pressure, heart rate, and
\ncholesterol level came down. Faecalibacterium
\nprausnitzii–a bacterium with anti-inflammatory properties–flourished,
\nincreasing from an undetectable percentage to 14.5% of his total gut bacteria.
\nThe changes persuaded him to focus on the microbiome’s role in his transformation.
\nHe started with mice but has since expanded his research to humans. [bold emphasis

\nhow our gut microbiome interacts with environmental factors, including our
\ndiet, is becoming an important concept in psychiatry. A 2015 review reports:<\/p>\n\n
\ndisorders the leading source of disability globally, the identification of new
\ntargets for prevention and management is imperative. A rapidly emerging field
\nof research suggests that the microbiome-gut-brain axis is of substantial
\nrelevance to mood and behaviour. Similarly, unhealthy diet has recently emerged
\nas a significant correlate of and risk factor for depression. This review
\nprovides evidence for the gut microbiota as a key factor mediating the link between
\ndiet and depressive illness.<\/i><\/p>\n
\ntechnologies is affording a better understanding of how diet influences gut
\nmicrobiota composition and activity and how this may, in turn, influence
\ndepressive illness. New interventions are also suggesting the possible utility
\nof pre and probiotic formulations and fermented food in influencing mental
\nhealth.<\/i><\/p>\n
\nstages, the emerging field of research focused on the human microbiome suggests
\nan important role for the gut microbiota in influencing brain development,
\nbehaviour and mood in humans. The recognition that the gut microbiota interacts
\nbidirectionally with other environmental risk factors, such as diet and stress,
\nsuggests promise in the development of interventions targeting the gut
\nmicrobiota for the prevention and treatment of common mental health disorders.<\/i><\/p>\n<\/blockquote>\n
\nin Gut<\/i> reported that athletes had
\nmore diverse microbiomes than controls. Another recent study showed that
\nchildren who exercised had positive effects in their developing microbiome. Science Daily<\/i> writes:<\/p>\n\n
\npublished in the journal Immunology
\nand Cell Biology, indicates that there may be a window of opportunity
\nduring early human development to optimize the chances of better lifelong
\nhealth.<\/i><\/p>\n<\/blockquote>\n\n
\nhealth, both metabolic and mental, and people are only now starting to look at
\nthe plasticity of these gut microbes,” said Monika Fleshner, a professor in
\nCU-Boulder’s Department of Integrative Physiology and the senior author of the
\nnew study. “That is one of the novel aspects of this research.”<\/i><\/p>\n<\/blockquote>\n
\nFuture Impacts<\/b><\/p>\n
\noffspring could be affected by continuing with the unhealthy habits of consuming
\nthe low fiber diet of its parents. Specifically, diversity could not be
\nrecovered if the next generation wasn’t munching on fibers… and that’s bad
\nnews. A diverse gut is a healthy gut. <\/p>\n
\n(Proton Pump Inhibitors) Harm Gut<\/b><\/p>\n
\nreflux disease (GERD) could negatively impact the microbiome:<\/p>\n\n
\nWe identified a significantly lower abundance in gut commensals and lower
\nmicrobial diversity in PPI users, with an associated significant increase in
\nthe abundance of oral and upper GI tract commensals. In particular, significant
\nincreases were observed in Streptococcaceae. These associations were replicated
\nin an independent interventional study and in a paired analysis between 70
\nmonozygotic twin pairs who were discordant for PPI use. We propose that the
\nobserved changes result from the removal of the low pH barrier between upper GI
\ntract bacteria and the lower gut. <\/i><\/p>\n<\/blockquote>\n\n
\nOur findings describe a significant impact of PPIs on the gut microbiome and
\nshould caution over-use of PPIs, and warrant further investigation into the
\nmechanisms and their clinical consequences.<\/i><\/p>\n<\/blockquote>\n
