What can only 5 days of eating UPF do: Study

Recent research found that 60% of the daily intake of Americans’ calories come from ultra -processed foods.

UPFs often contain high levels of sodium, refined sugars, cholesterol fats and other laboratory-based ingredients.

A recent study linked exposure to UPFs with 32 poor health results, including a higher risk of cardiovascular disease, cancer, metabolic syndrome, overweight, non-alcoholic fatty liver, type 2 diabetes and even premature death.

Now, a new essential study suggests that many of those contrasting effects can be dangerous to win and shocking long.

Researchers at the Institute for Diabetes Research and Metabolic Diseases of the Helmholtz Munich Center at the University of Tübingen found that even in the short term, consuming a high -calorie diet rich in UPF, damages the response of brain insulin and increases liver fat in healthy men.

What more is there, and worse? These effects last long after the consumption period.

Insulin regulates appetite and metabolism, and insulin resistance – as the type caused by UPF – compromises this regulation and contributes to overweight, type 2 diabetes and cognitive dysfunction.

The German team also found a link between elaborate ultra food consumption and interruption in response to brain reward learning, suggesting that as little as five days of overeating can condition the brain for unhealthy eating models.

For the study, 29 healthy male participants between 19 and 27 were divided into a high calorie diet (HCD) or a control set.

Over the past five days, the HCD group was told to eat extra daily calories from foods with processed ultra snack.

The control group maintained their regular diet.

The study intended to evaluate insulin -induced brain activity during three moments: before the high caloric diet during it, and a week after the subjects returned to eat normally.

On average, the HCD group increased their daily calorie intake by 1,200 calories.

The fat content of the liver in that group increased dramatically, while the responsibility of the insulin of the brain also increased.

One week after the resumption of a regular diet, insulin activity was significantly lower in the brain.

A previous study published in Jama Neurology found that people may be at a higher risk of cognitive decline if more than 20% of their daily caloric consumption are ultra -processed foods.

In the German study, researchers were amazed at the effect that the short -term HCD had on the teaching of reward, the process with which the brain learns to accompany behaviors or stimuli with a positive or negative result and modify accordingly. This process is important for motivation, decision -making and food choices.

To measure the relationship between HCD and the teaching of the reward, participants ended up a task of measuring their sensitivity to the reward and punishment and efficiency of the brain in processing and adapting the feedback.

After a few days of UPF eating, the HCD group showed a decrease in the sensitivity of reward and increased the sensitivity of punishment. After a week of normal meals, this trend was reduced, but did not completely return himself.

“Data suggests that a short -term HCD, rich in sugar and saturated fat, has prolonged effects on the brain that exceeds the time frame of its consumption,” the research team claims.

“The usual daily intake of sweet and fatty foods has been shown to increase nerve responses to food, while reducing the preference for low -fat nutrition independent of changes in body weight and metabolism.”

While the study is specific to gender and more research is needed, the team presents, “brain response to insulin adapts to short -term changes in the diet before weight gain and can facilitate the development of overweight and associated diseases.”

Disease control and prevention centers (CDC) define overweight as an index of body mass (BMI) of at least 30, and a 20% shocking Americans meet those criteria.

Nearly 60% of American adults with overweight have high blood pressure, and approximately 23% have diabetes. People with overweight are at a higher risk of a variety of health problems, including heart and liver disease at the top of a number of chronic conditions.
