　　High blood sugar levels are a risk factor for type 2diabetes.

　　Doctors today have only general dietaryrecommendations for how to control those levels,because there's no real way to predict what's calledthe post-prandial glycemic response-that is, justhow your particular blood glucose level will be affected by what you eat.

　　But a new study may be the start of making glucose controlling food recommendations morepersonal.

　　Scientists in Israel followed 800 nondiabetic adults over one week, checking their blood glucoselevels every five minutes.

　　The participants got a full medical workup, including a stool sample to analyze their gutmicrobiome.

　　The participants logged the food they ate, their exercise and their sleep.

　　They chose their own food except for one meal a day, which was one of four standardizedoptions.

　　The result? “The blood sugar response of different people to identical meals can be hugelydifferent.”

　　Eran Segal of the Weizmann Institute of Science.

　　Segal and his colleagues found that one person's blood glucose might spike in response to aparticular food, while that same food would actually lower another person's.

　　The study is in the journal Cell.

　　The researchers then developed an algorithm that could predict an individual's blood sugarresponses to various meals.

　　“We link nutrition in a personalized manner to human risk to develop elevated blood sugarlevels and their many complications.”

　　Eran Elinav of the Weizmann Institute, who also took part in the study.

　　“As scientists we often deal with very basic questions, but in this work we are very happy toalso introduce a potential that if further developed would allow to benefit the health of millionsacross the world.”
