We already knew that junk food (understand: hamburgers, fries, nuggets, pizzas…) was bad for your health: in bulk, it is accused of promoting obesity, asthma in teenagers , poor school results, certain hormonal disorders, fertility disorders in men, constipation… In short, to be avoided!
But according to a new study conducted jointly by researchers from Brigham Young University (in the United States) and Shanghai Jiao Tong University (in China), stress could have the same negative impact as a diet that is too fatty, too sweet and too salty on the intestinal microbiota.
To reach this conclusion, the researchers conducted several experiments on a group of mice, aged 8 weeks on average: half of them were subjected to a “fast food” type diet for several weeks. During the same period, the other half, on the other hand, was subjected to intense stress. The intestinal flora of the rodents was then analyzed via their stools.
Are women more sensitive to stress than men?
Verdict? The researchers found that, in female mice in particular, stress caused the same change in gut flora as a diet that was too fatty, too sweet and too salty.
“Although this work was carried out on mice, we believe that certain conclusions are also valid for humans, analyze the scientists, who published their work in the specialized journal Scientific Reports. Thus, stress is not only psychological: we know that it can have concrete repercussions on a person’s state of health. Regarding the male/female difference, it also seems credible on a human scale since women are, on average, more affected than men by depression and anxiety disorders. »
