Is Whole Grain Bread Healthier Than White Bread

In their previous work, they found that different people response with different blood sugar levels to the same diet. Based on this, the researchers suspect that there may be more complicated things: perhaps the blood sugar response of some people in the study is better for some kinds of bread, and some people are better for another kind of bread. Further study showed that this was really the case. About half of people responded better to processed white bread, while the other half responded better to whole grain bread. The lack of difference is found when all the findings are averaged together.

Eran Elinav, a researcher in the Immunology Department of the Weizmann Institute, said: “The findings of this study are not only fascinating, but also potentially important, because they point to a new paradigm: different people respond differently to the same food. So far, the nutritional value assigned to food is based on a small number of scientific studies, which unfortunately does not hold true in this case."

He added: "This discovery will help to research more reasonable methods to tell people which foods are more suitable based on their microbiota."

Professor Avraham Levy of the Department of Plant and Environmental Sciences warned of the study: “In these experiments, participants were required to eat exactly the same amount of sugar in the bread, which means they ate more whole grain bread because whole grain bread contains fewer sugar. In addition, we know that because of the higher fiber content of whole grain bread, people generally eat less whole grain bread. We did not decide how much to eat based on how full you are, so research will continue to get on."
