A new study from Australia showed that there is a clear link between stress, obesity, and neurons in the brain. Experts also prevent indulging in comfort food when feeling stressed, as this may lead to an immediate increase in weight. ( Pixabay )
Yielding to comfort food when feeling stressed brings instant gratification. However, stress the power ignites the body to store fat – an instant way to gain weight.
The problem with the comfort of a & # 39 products is that they & # 39 are sugary, high-fat and full of calories. Among the most harmful to the health of comfort foods include macaroni and cheese, which has enormous 380 calories, fried chicken and the wafer more than 1000 calories and chicken pot pie with 370 calories and 850 mg of sodium, which is almost half of sodium human consumption for the day;
stress risks Jerzy
A study conducted by a team of experts from the Garvan Institute of Medical Research in Australia has shown that high-calorie diet combined with stress, as a result of an increase in weight compared with the same diet, consumed under stress.
The researchers also found that the food they consider the center of the brain of comfort, which is located in the hypothalamus, which regulates food intake and within the central amygdala, which controls emotional response.
According to the study, which used mice experiments, the neurons in the central amygdala called neuropeptides NPY or responsible for heightened response to combined stress and interference with high-fat diets.
"This study shows that we need to be much more conscious about what we eat when we are stressed, to avoid a more rapid development of obesity," said Herbert Herzog, head of the Laboratory of eating disorders Garvan Institute.
Studies have also shown that insulin controls the molecular pathway in the brain, which activates during stress and leads to a greater increase in weight. In the same way, stress in combination with high-calorie causes insulin resistance in the central amygdala. It's a vicious circle, which inevitably leads to obesity, when the supply voltage is out of control.
Insulin and stress
Insulin with a & # 39 is a hormone that helps the body to absorb glucose and keeps your blood sugar balanced. Insulin resistance makes it more difficult for the body's cells to take in glucose. Chronic stress alone only slightly increases the level of insulin in the blood, but in combination with comfort products, insulin level may increase up to 10 times higher.
If tonsils becomes insulin resistant or insensitive, nerve cells to increase their level of NPY, and in turn, contributes to slow food and fat burning.
Team Garvin say, when the production of neuropeptides in the amygdala possible weight gain is reduced. Similarly, if there is no NPY, weight gain on a high fat diet with stress is on the same level as the increase in weight in an environment without stress.
In the study, indicating that insulin has a more widespread effects in the brain than previously thought, scientists hope to continue to study the effect of insulin in some brain functions.
