We have all experienced the following and frustrating situation: we need to lose some weight or control our pre-diabetes or a high blood pressure, but although we go on a diet prescribed by our family doctor and stick to it rigorously, it does not work. Why? Until now, there were foods considered to be healthy and with low caloric contribution, such as tomatoes, salad or cereals. And others like pasta or bread, which were exiled from every diet. But, what if a tomato were not a healthy food for us all? And, instead, a pizza could be not so bad as we have believed for some individuals?
Studies have found the reason is high variability in post-meal blood glucose response. Niv Zmora is a postdoctoral researcher at ElinavLab, at the Department of Immunology at the Weizmann Institute of Science (Israel); he studies the interactions between immune system, microbiota and their effects on health. In this sense, he is investigating with his group colleagues how to create personalised diets with an accurate predictor of blood glucose response that could integrate physical exercise, gut microbiota and some dietary habits to lower in successful way postmeal blood glucose, and thus its metabolic consequences. Zmora assisted to the Gut Microbiota for Health World Summit held in Paris, in March 2017, where we could interview him.
