Research over the past few years has clarified the importance of our individualized gut microbiome in disease and overall health. This observation led scientists from Tel Aviv to monitor food intake, blood-glucose levels and microbiome composition in 1000 patients over the course of 50,000 meals. They found that different individuals tolerated food differently, including some people who could process “unhealthy” foods with ease. Using this data they tailored diets to pre-diabetic patients based on microbiome composition and observed a decrease in blood-glucose spikes. This concept could lead to individualized, or at lease “grouped”, diets.
