As we age, we can potentially be at increased risk of age-related diseases. How can we care for them as we age? Is it possible that an A- grade environment could help us lead a longer, healthier life?

I know a few people who have been put on antibiotics for infections in the winter. These drugs can cause mass destruction of gut microbes and wipe out the good along with the bad. People who take them might be able to restore a healthy environment.

Scientists looked at thousands of samples of people's gut microbes to see how they change with age. The best way to find out what is in a person's gut is to look at feces. When we have a bowel movement, we lose a lot of gutbacteria. It is possible for scientists to find out which types ofbacteria are in your body. The data that had already been collected from 21,000 samples of human feces was analyzed in this study. Europe, North and South America, Asia, and Africa were some of the places where these came from. There were 19 nationalities represented. All of the samples were from adults.

As we get older, the authors of this study wanted to know more about what makes for a good microbiome. It has been hard for microbiologists to come up with a solution. Somebacteria can make compounds that are good for us. It gets more complicated when it comes to the entire system. The accepted wisdom is that variety is a good thing. The team looked at how the microbiomes of younger and older people differed. The scientists found that the microbes in our guts tend to become more unique as we get older. The development of those age-related symptoms, which we would rather stave off for as long as possible, seem to be linked to this unique trait. Measuring diversity alone doesn't tell us much about whether the bugs in our guts are useful or not The Anna Karenina principle is that all happy microbiomes look alike and each unhappy one is unhappy in its own way. Is a diet with lots of fruit, vegetables, and fiber good for the gut? A couple of years ago, researchers found that after a year on a Mediterranean diet, older people saw changes in their microbiomes that might benefit their health. Changes to our diet can have an effect on our health. That doesn't mean that they'll survive the journey to your gut We don't know if they'll be able to form niches in the existing environment or if they'll cause some sort of disruption. Some organisms will respond well to sauerkraut and others will not. If they turn out to support my microbiome in a way that protects me against age related diseases, that is just the icing on the less-microbiome-friendly cake.

Microbiome tests at home can tell you which bugs are in your poo, but not much more than that, as Emily Mullin discovered. It seems to work for monkeys, as evidenced by the fact that Adam Piore tried it. Even if you live longer on the diet, you won't like it.
