You've heard of pre-biotics and pro-biotics, but now you'll be hearing a lot more about post-biotics. Researchers at McMaster University have begun to identify how post-biotics, or the by-products of bacteria, lower blood glucose and allow insulin to work better.

Jonathan Schertzer, assistant professor of biochemistry and biomedical sciences and senior author of a paper published by Cell Metabolism today, explains it this way:

"We know that , often called the microbiome, send inflammation signals that change how well insulin works to lower .

"It was previously thought that bacteria only caused problems such as higher inflammation and higher blood glucose. But this is only half of the story. We discovered that a specific component of bacteria actually lowers blood glucose and allows insulin to work better during obesity.

"Understanding how different parts of bacteria control glucose could lead to new therapies that avoid some of the problems with pro-biotics or pre-biotics. We have found a "post-biotic" that lowers blood glucose during obesity."

This work is important as more than half of Canadians are overweight or obese, which leads to higher levels of blood insulin and glucose. These features of prediabetes can lead to type 2 diabetes.

"But we haven't understood what triggers elevated blood glucose," said Schertzer. "This is significant because only some individuals with obesity develop prediabetes. Blood glucose is influenced by our genes, the food we eat, and the bacteria in our gut."

His research team is working to develop new bacterial-based drugs to lower and combat prediabetes before type 2 diabetes develops. At this time, they have had success in trials with mice with a drug currently used for osteosarcoma, a bone cancer.

I was diagnosed with type 2 Diabetes and put on Metformin on June 26th, 2016. I started the ADA diet and followed it 100% for a few weeks and could not get my blood sugar to go below 140. Finally i began to panic and called my doctor, he told me to get used to it. He said I would be on metformin my whole life and eventually insulin. At that point i knew something wasn't right and began to do a lot of research. On August 13th I found a blog http://mydiabetes...iabetes/ I read that article from end to end because everything the writer was saying made absolute sense. I started the diet that day and the next morning my blood sugar was down to 100 and now i have a fasting blood sugar between Mid 70's and the 80's. My doctor took me off the metformin after just three week of being on this lifestyle change. I have lost over 30 pounds and 6+ inches around my waist in a month. The truth is we can get off the drugs and help myself by trying natural methods
