We’ve probably all been there-a friend swears by her new diet, but when you give it a try, you don’t see the same results. What gives?
According to a new study conducted by the Weizmann Institute of Science in Israel, individual people can have extremely different responses to the same foods, and universal diets and dietary recommendations might not be as helpful as previously thought.
Eight hundred non-diabetic(糖尿病的) people participated in the week-long study, during which they received standardized meals for breakfast. The participants used a mobile app to report their lifestyle habits and food intake, and additional data was collected through health questionnaires, blood tests and body measurements.
Although the glycemic(血糖的) index ranks foods based on how they affect the blood sugar levels of groups of people, the researchers saw that how the food was metabolized varied greatly from person to person—and that the glycemic index depends largely on the individual. The age and body-mass index(BMI) of the participants were found to be strongly linked with differences in metabolism, as were gut microbes.
The individualized feedback was particularly compelling, and provided support for the importance of personalized nutrition plans. One woman’s blood sugar spiked when she ate tomatoes-a food that any universal diet would have advertised as a healthy choice. “For this person, an individually tailored diet would not have included tomatoes but may have included other ingredients that many of us would not consider healthy, but are in fact healthy for her,” Eran Elinav, one of the researchers, said in a statement.
Because the increase of blood glucose levels can lead to pre-diabetes and has been linked to obesity, non-alcoholic fatty liver disease, and heart disease, these results are crucial to understanding how to best help people identify which foods are best for their health.
“After seeing this data, I think about the possibility that maybe we’re wrong in our thinking about the obesity and diabetes epidemic,” said Eran Segal, the other lead researcher.

Your co-worker brings in brownies, your daughter makes cookies for a holiday party and candy is arriving from far-flung relatives. Sugar appears on almost all joyful occasions. It is celebration, festivity and family love. It’s also dangerous. Sugar, perhaps more than salt, contributes to the development of cardiovascular disease. Evidence is growing that eating an undue amount of sugar can lead to fatty liver disease, hypertension, Type 2 diabetes, obesity and kidney disease.
Yet people can’t resist it. And the reason for that is pretty simple. People just can’t resist it. And we don’t mean disability to resist it in the way that people talk about delicious foods. We mean the weakness, literally, in a similar way of drugs due to the fact that the sugar manufacturers are doing everything they can to keep us hooked.
Just a few hundred years ago, concentrated sugars were essentially absent from the human diet. Sugar was a rare source of energy in the environment, and strong longings for it benefited humans for living on. Sugar longings initiated searches for sweet foods, the kinds that help us layer on fat for times of scarcity.
Today concentrated sugar is everywhere, used in approximately 75 percent of packaged foods purchased in the United States. The average American consumes anywhere from a quarter to a half pound of sugar a day. If you consider that the concentrated sugar in a single can of soda might be more than what most people would have consumed in an entire year just a few hundred years ago, you get a sense of how dramatically our environment has changed. The sweet longing that once offered an advantage now works against us.
A better approach to sugar rehab (康复) is to promote the consumption of whole, natural foods. Substituting whole foods for sweet industrial synthetic foods may be a hard sell, but in the face of an industry that is exploiting our biological nature to keep us addicted, it may be the best solution for those who need that sugar fix.
