An experiment conducted by scientists from Australia’s Macquarie University, has shown that only one week the so-called “Western diet” – the consumption of fatty and sweet food markedly impairs hippocampus, the brain area that regulates memory and appetite.
Experts from the Australian Macquarie University, whose work tells the Guardian, conducted an experiment whose purpose was to determine how affects the brain a diet high in fat and sugar. The study has attracted 110 young people aged from 20 to 23 years, none of whom suffered from obesity and other diseases.
Half of the volunteers had during the week to adhere to the “Western” diet that involves the consumption of large quantities of junk food and sweets – in this case, Belgian waffles. The second half was fed as usual. The experiment lasted a week, and the first and last days, subjects ate Breakfast in the laboratory. Here they are before and after eating took tests on memorizing words and evaluated on taste certain types of food.
It turned out that only one week of “Western” diets worsened the results of memory tests. However, this reduction was small. Scientists are much more alarmed by the fact that volunteers adhere to such a diet are more inclined to eating sweets and fast food right after Breakfast, when it was full.
According to the authors, this suggests that a diet high in fat and carbohydrates makes it difficult for the regulation of appetite. The result is a positive feedback, leading to chronic overeating, obesity and related diseases.
The root of the problem may lie in damage to the hippocampus – a brain area that is responsible for the regulation of memory and appetite. Previous animal studies have shown that it suffers from a diet high in sugar and fat. Perhaps in the normal hippocampus blocks the memories of eating when we are full, so the desire to eat more arises. However, if it is not working properly, the food seems more attractive.
If sweet and fatty foods really change the perception, that to combat the obesity epidemic it is necessary to adopt the most stringent measures. Calls to regulate such food at the state level – as well as regulates the sale of tobacco.
