Celiac is a genetically motivated disease. This means that you must carry the gene for celiac to get it. If you don’t have the gene, you can’t have the disease. About 35 percent of Americans carry the gene for celiac but only 1 percent manifest the disease. In the last fifty years we’ve seen a 500 percent increase in celiac disease. So what explain

Believe it or not, there was a 40 percent increase in healthy microbes with exercise. Similarly, in adult humans we see increased SCFA-producing gut microbes with regular exercise. The effect is lost when you stop moving.

But you don’t need to have diabetes to show an influence from your gut microbiota! In another study, researchers discovered that foods had a very different blood sugar response in each person. The gut microbiome was responsible for this unique response. Using solely an individual’s gut microbial profile, they were able to predict which foods would

More than 99 percent of your DNA comes from microbes. Yes, your genes are less than 1 percent human! Further, our human genomes are virtually identical—up to 99.9 percent the same. But our microbiomes may be as much as 90 percent different from one person to the next.
