A healthy kidney can help digest food and absorb nutrients, improve the immune system and reduce the risk of certain chronic diseases.
However, not everyone knows that a healthy brain tract also has an important impact on mood. About 90% of the body's serotonin and more than 50% dopamine are produced in the brain tract. These two neurotransmitting substances can make people feel good, so scientists often call the kidney tract the "second brain".
"One apple a day, the doctor is far away from me" is widely transmitted, but research shows that one orange a day may help prevent depression.
Harvard Medical School doctor Raaj Mehta and colleagues analyzed data from more than 30,000 women and found that people who consume large amounts of citrus had a much lower chance of developing depression than others.
Their research results were published in the journal "Microbiome" at the end of last year.
Meta told Harvard Gazette last month: "We found that eating a medium-sized orange a day may reduce the risk of developing dementia by about 20%. "
"And this effect seems to be unique to citrus. When we study our overall fruit and vegetable feeding, or other single fruits such as apple or banana, we did not find any connection with the risk of developing dementia."
Through stool samples, researchers found that eating more citrus and Clostridium prasgid (F. prausnitzii) increases related to the fact that this beneficial tract bacteria is known for its anti-inflammatory properties, but may also help the transmission of serotonin and dopamine to the brain.
A study published in 2022 found that eating less citrus fruits among patients with chronic health conditions is obviously related to higher risk of depression.
However, the researchers also acknowledged that there are certain limitations in this study, because most of the participants were middle-aged white women, and in addition, despite several factors under control, their research results may still be related rather than causal.
Nevertheless, eating orange or lemon or grapefruit a day will definitely not cause any harm. This study also explains the relationship between the brain and the brain, and the role of these fruits in it.
Meta said: "I hope our research results will inspire other researchers to study the relationship between diet and mental health. I think people directly know that the food we eat will affect mood. We even describe this situation, that is, time-honored food comfort. foods, this type of food can make us feel better in the short term. "
"There is a large part of the need for treatment of depression that is not met, and eating citrus will not really have any serious side effects, so it would be great to see this simple treatment method useful."
