If you care about the health select only whole wheat bread, then we hasten to disappoint you: you, too, fell for marketers. A recent study proved that there is no difference, you will eat the "right" bread or plain white bread.
As the study was conducted
According to the National Food Research UK (UK National Food Survey), sales of white bread, have fallen by 75% since 1974. While the sales of black and wholemeal bread increased by 85%, as this bread was considered a healthier alternative to white.
Experts from the Israeli Weizmann Institute examined the intestinal bacteria, as well as the measured level fat, cholesterol, glucose and essential minerals such as calcium and iron, in the body 20 healthy people.
One half of the participants in a week eat whole wheat unleavened bread, the other - the same amount of white bread from a conventional store.
As a rule, study participants ate an average amount of bread - about 10% of daily calories.
During the week, some of them ate only white bread magazine, and the other - home black, which was 25% of daily calories. Then, the subjects did a two-week break and switched diets.
conclusions of scientists
"Unhealthy" Bread does not show
"Despite our expectations, the test showed that the differences between these types of bread clinically not reflected in our study parameters, - said Professor Eran Segal, a leading specialist research. - We found no appreciable differences between the observance of a diet and a conventional diet. "
Small sample does not show nuances, but shows the main
"The study clearly shows: the use of black or white bread does not affect the studied options - says Susan Jebb, in the field of nutrition and health professor at Oxford nation University. - Maybe it's too small a group of participants that we were able to identify subtle differences. But the results of the study are as follows: one or the other kind of bread did not have any significant measurable effects on health. "
Professor Jebb warns that a small control group does not allow to study other factors that could affect the outcome.
Study participants are changing habits
"People taking part in the study, often alter their behavior in various ways. For example, if we ask the participants to change their consumption of bread, then they can, without noticing, at the same time change in the diet something else, "- said Professor Jebb.
However, different people, in principle, react differently to the same food. It all depends on the individual intestinal microflora. Experts also warn that you should not rush to conclusions, because the experiments took place on a small sample and just a week of use of each type of bread.
