A new study of mice suggests bacteria may help to cause anxiety and depression in overweight people. The research raises questions about whether changing organisms living inside our bodies or changes in diet could help treat these conditions.
A 2017 study found that one-third of the world’s population is overweight or considered obese. When people become obese, this changes the processes by which the body uses food to make energy, build tissue and remove waste material. Left untreated, these changes can lead to diabetes. Diabetes is a serious condition. It affects how your body uses blood sugar. Obese people also have higher rates of anxiety and depression than other individuals. Ronald Kahn studies diabetes at Harvard Medical School in Massachusetts. He says researchers have wondered if people suffer from depression because they are obese or because of their metabolism(新陈代谢).
“And we asked the question, ‘Maybe the metabolic link is at least partly fueled by the microbiome(微生物组),’” Kahn said. The microbiome is the community of bacteria, fungi and other microorganisms living in your stomach. It changes with your diet. And Kahn said those changes might affect both the body and mind.
To test the theory, he and his research team fed mice a high-fat diet and studied their behavior as the animals became obese. In one test, they put mice in a box divided into a darkened area on one side and a light area on the other side. They found that the more nervous, anxious mice liked to spend time on the dark side.“And a mouse on a high-fat diet will spend more time in the dark than a mouse on a normal diet. So, they have more sign of anxiety,” Khan said.
The anxiety went away when the mice were given antibiotics(抗生素).
The researchers said this suggested that the bacteria were helping make the mice nervous. The researchers then wanted to see if they could produce the same effect by giving the same bacteria to animals raised in a bacteria-free environment, with no microbes of their own. They found that it did. Microbes from obese mice made the bacteria-free mice anxious. Microbes from obese mice given antibiotics did not.
