In Dutch there is a saying “ieder pondje gaat door het mondje”, meaning that every pound of added weight is because of what you ate. But as someone who can eat a lot without gaining weight, I know that this is not true for everyone. And it’s a question that has intrigued researchers in Israel: what causes these differences?
Initial results from their ongoing study of one thousand people suggest that foods high on GI (Glycaemic Index) do not necessarily cause a spike in blood sugar level, while “good” foods – which are low on GI – can in fact raise the blood sugar level. And it appears that the microbes in our gut – which are distinctly different from person to person – play an important role in controlling the way our bodies react.
