It disclosed the secret appeal of potato chips, chocolate and peanut butter

Monika Pischetsrieder (Monika Pischetsrieder) with colleagues from the University of Erlangen in Germany found , rats, having a choice, tend to food with a certain combination fats and carbohydrates. Magic formula - 50 to 35, that is the food, which contains 35% fat and 50% carbohydrates. This is almost identical with potato chips, chocolate and peanut butter. The study was published March 17 in the journal Nature .

In the evolution of the organism has learned to accumulate as many calories "for a rainy day." The brain is getting calories, produces dopamine, encouraging the absorption of nutritious food. On this basis and on the background of the availability of food in some people and generated a tendency to overeat, leading to obesity. Scientists call this phenomenon & quot; hedonic hyperphagia & quot; - A tendency to absorb food that is not related to the need to replenish energy reserves.



There is a view that the brain simply prefer high-calorie food. The researchers tested the correctness of this assertion - whether experimental rats to choose their food on the content of calories, or give preference to any of the combinations of nutrients.


Three groups of rats received different food: the first - chips in unlimited quantities, and the second - the usual food, the third - the food with the same ratio of fat and carbohydrates, as in chips. Then, using MRI, researchers have studied what part of the brain involved in the reactions to food.



Rats happily devoured the food that has the magic formula 50:35. Most of the test in one sitting ate half the daily allowance. It is known that carbohydrates - this is a very "fast" calories, which the body converts into energy immediately. Per unit mass of fat contains more calories, but they are harder to remove, and they are used "in reserve". Most likely, in the course of evolution so it was that a combination of "50 to 35" is the most energy efficient.

Man - not a rat, but most people really can not resist chips, and before going to eat up all the chips from the open package as a whole. Chocolate is also known not only as a means for the rapid saturation, but also food for the rapid uplift your mood - apparently, the brain rewards its owner for the energy flow in the correct proportions.



Hmm. Is it time to drink tea? ..
