Biologically explain the love for fast food is not too difficult: burgers, fries and chicken wings with all the accompanying rich energetically favorable and difficult to find in the nature of animal fats. Add the aggressive advertising, the sense of saving time and money - and we are ready to eat, eat and eat again. The problem of overeating and obesity following it all growing and expanding, so look for "ideals" have to learn from experience and deal with them.

In 2010, the U.S. Congress ordered the restaurants to bring to its customers information about calories with the expectation of abstinence consumers. Will this decision have any influence on the health of the nation or no - we hardly can know, but the client information had no effect to the choice of food.

Brian Elbel and his colleagues from the Medical School of the University of New York conducted a large-scale study of preferences patrons of fast food before and after the introduction of this rule. It is the "big apple" is the first city that introduced mandatory labeling of calories.

For this purpose, the authors published in the International Journal of Obesity (it goes without saying that most of the international publications come from a country of democratic freedoms) were interviewed and collected checks from visitors of restaurants "big four" - McDonalds, Burger King, Kentucky Fried Chicken and Wendy's.

In his research, scientists have found that children and teenagers unattended for one visit eats significantly more (725 calories vs. 608) than with a hike with their parents, and these figures after the information of the population has not changed.

Elbel work will be more than helpful for marketers: scientists have found that price plays a role in choosing the dishes, but not the restaurant. A decisive factor is still the taste (72%), which is helpfully tells us the information in one of these network catering to a large extent on the fat content.

As for the caloric and nutritional value, it is, in his own assurances, guided by only 9% of respondents. But those bad either being able to consider, whether based on the standards for athletes still eat their deserved 700 calories per visit.

And this despite the fact that over 57% of respondents said they noticed calorie warning, and 28% - about the fact that this information influenced their choice, although it was not decisive.

That is, if some of the clients, consciously or unconsciously piece sacrifice to please the taste, then a second, albeit much smaller, actively deceiving themselves, ostensibly guided in choosing calorie meals. There is no need to say that the average calorie portion has not changed in the two years after the introduction of regulation, to some extent Congress can record yourself and plus: for, at least, it has not grown.

In our context, still want to rely on a more active information support of the state - tax deductions from fast food are unlikely to overcome the costs of medical care obese, diabetic and other victims of the metabolic syndrome. Although, of course, the link between fast food and thick subcutaneous tissue still has not proved.
