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.
