He had not participated in a clinical trial of some new secret weight loss pill, or signed up for a punishing Biggest Loser-style exercise program, nor had he been fussed over by behavioral scientists who made his plates and drinking cups smaller with each passing week.

One of the huge mysteries in studies of diet and exercise is the difference between people who get the same treatment but have remarkably different outcomes. Inevitably, some people in a study show little improvement despite weeks or even months of following what might seem like draconian changes in their normal diet and lifestyle.

Other people apparently drop weight just by getting out of bed in the morning, and also improve their circulating triglycerides, total cholesterol, and biomarkers of inflammation with apparent ease.

We all know someone like this in our daily life. But why are there such extreme differences between people? Is our DNA to blame? In addition to the familiar human genome that we inherit from our moms and dads, each of us also has hundreds of trillions of microbial symbionts, each with their own genomes.

Research programs such as the Human Microbiome Project have revolutionized our understanding of our microbial bodies, which outnumber our human cells ten to one, and account for more than 2 pounds of our body weight. We know microbes can change profoundly in each of us throughout life, and that we can change them through diet, medications we take, hygiene, etc.

We know that people in more traditional societies have different microbes than those in more Westernized populations, and that diet can play a role in these differences.

You can also change the health prospects of a mouse overnight by changing its diet and thus its microbes. Advances in bioinformatics fancy word for data analysis and refinements of DNA techniques — not too mention a significant increase in computing power — is changing everything.

The evidence that life events and diet can shape our gut microbes is increasing, but which direction should we nudge them? What is a healthy or optimal mix of gut microbes? In the meantime, as you contemplate your New Years resolution to join the gym againlose weight, improve your diet, or to purchase the latest gizmo to track your every move, you might want to consider whether your microbes will support your decision.

Take that you anthrocentric ape! Below are five suggestions on how you might improve the health of your gut microbes and some other microbes in your life in But it gets worse: This, coupled with the low therapeutic doses in animal feed — and ipso fact our feed, may be shifting our gut microbes into an unhealthy state and possibly contributing to the metabolic disease of obesity.

During this period of imbalance, opportunistic pathogens can set up shop. While antibiotics are clearly needed in some probably most scenarios, ask more questions in before downing them without a care.

Though keeping the outside out does have its advantages — protection from the elements and decreasing your chances of being eaten by a zombie — it has also changed the microbiome of our home. Studies show that maybe opening window and increasing natural airflow will improve the diversity and health of the microbes in your home, which in turn benefit the inhabitants.

In the not-so-distant future, building codes will likely reflect the biological benefits of rewilding our living and workspaces.The good news is that you can change your gut microbiome. You see, the average lifespan of a bacterium in your microbiome is 20 minutes!

So you have the opportunity every time you eat to begin to change the population of your gut microbiome.

The daily effects of the human microbiome

The human microbiota is the aggregate of microorganisms that resides on or within any of a number of human tissues and biofluids, including the skin, mammary glands, placenta, seminal fluid, uterus, ovarian follicles, lung, saliva, oral mucosa, conjunctiva, biliary and gastrointestinal tracts.

They include bacteria, archaea, fungi, protists and viruses. The body is home to trillions of microorganisms known as the microbiome. Learn more about the role of diet, probiotics, and future research areas.

Nov 11,  · Diet and nutritional status are among the most important, modifiable determinants of human health. The nutritional value of food is influenced in part by a person’s gut microbial community (microbiota) and its component genes (microbiome).
