Chronic diseases like cancer, autoimmune disorders and obesity may ultimately vanquish the efforts of medical intervention unless people change their diet, according to Matt Orr<\/a>, an assistant professor of biology in the College of Science at OSU-Cascades.<\/p>\n

The findings<\/a> were published this week in the Quarterly Review of Biology.<\/em><\/p>\n

Orr describes a \u201crestoration ecology\u201d approach toward patient health, comparing every person to an ecosystem in which effectively fighting chronic disease requires fostering the communities of symbiotic gut microbes that people need for their health.<\/p>\n

That means drawing on techniques, developed by scientists over the last half-century that have restored species diversity and ecosystem function of natural habitats.<\/p>\n

\u201cWestern doctors generally ignore diet in chronic disease, even diseases of the gut,\u201d said Orr, inspired to do this research in part by his own health challenges. \u201cThey do not overly encourage or support their patients to change their diet away from high fat and high sugar. Industry and policy have created a platform for people to eat terribly in this country, and many Americans do eat terribly.\u201d<\/p><\/blockquote>\n

The new study notes that throughout history humans have harmed beneficial species, often inadvertently, through advances of culture and technology. Affected species include those inside of people as well as around them.<\/p>\n

The highest known cell density of any microbial habitat on the planet is found in the human gut \u2013 there can be more than 1,000 species of bacteria containing more than a half-million genes.<\/p>\n

But Orr and his collaborators found that applying techniques of ecological restoration \u2013 assisting the recovery of an ecosystem that\u2019s been degraded, damaged or destroyed \u2013 to the field of medicine has been a largely unexplored option.<\/p>\n

Restoration techniques fall into one of two categories: passive and active. Passive means removing whatever disturbances have harmed an ecosystem \u2013 such as an unhealthy diet \u2013 and then letting the ecosystem heal itself.<\/p>\n

If that doesn\u2019t work, the next step is active restoration. In nature that could mean physical manipulation of a landscape, exterminating unwanted species and introducing desired ones. In the gut, it might involve probiotics, antibiotics or fecal microbiota transplants.<\/p>\n

One tenet of restoration ecology that is ignored by Western medicine is that active interventions will not succeed if a passive platform is not established. In other words, the disturbance has to be removed.<\/p>\n

Part of what compelled Orr to look at the human microbiota from an ecological perspective was the chronic gut irritation he developed from years of doing research in the tropics and taking antibiotics \u201cfor bugs picked up at unsanitary field stations.\u201d<\/p>\n

\u201cI was diagnosed with Crohn\u2019s disease and put on a monoclonal antibody inhibitor for life,\u201d he said. \u201cExcept that I cleaned up my diet, stopped getting the gut irritation, cut out the monoclonal antibody inhibitor, and my symptoms are gone.\u00a0Two doctors overturned the Crohn\u2019s diagnosis in writing.<\/p><\/blockquote>\n

\u201cAll of that inspired me to think about ways that my knowledge of restoration ecology might help to guide physicians away from treating and misdiagnosing other people the way that they had treated and misdiagnosed me.\u201d<\/p>\n

Gut microbes perform a wide range of beneficial functions. Among other things, they produce nutrients in the form of short-chain fatty acids and vitamins, control blood sugar and weight, reduce inflammation and even improve mental health and psychological well-being.<\/p>\n

And as with natural habitats, where successful restoration techniques will vary from year to year and place to place depending on individual circumstances, gut restoration requires a similar approach \u2013 one toward personalized medicine given that no two sets of gut microbiota are identical.<\/p>\n

Except for that they\u2019re all essential to the person\u2019s health and all subject to disturbances, including the food people eat and the medicine they take.<\/p>\n

\u201cNineteenth-century research identified microbes as agents of disease and set the stage for 20th-century breakthroughs in antibiotic therapies,\u201d Orr said. \u201cBut antibiotic resistance is now a global crisis, and we\u2019re also now aware that antimicrobials can harm beneficial species, too.\u201d<\/p>\n

Collaborating with Orr were Deborah Young, an\u00a0undergraduate biology major at OSU-Cascades, and physician Kathryn Kocurek of Fall Creek Internal Medicine in Bend, Oregon.<\/p>\n
