Citrus fruits as a key to reducing the risk of depression: new study finds positive effects

Depression remains one of the biggest global problems, affecting millions of people around the world. Experts estimate that about 5% of the adult population suffers from this mental disorder. Scientists have been studying the impact of diet and lifestyle on mental health for many years, and a study was recently published that points to a new way to reduce the risk of developing depression.

The study, published in the scientific journal Microbiome, demonstrated that regular consumption of citrus fruits has a positive effect on a person’s mental well-being. The scientific work was led by Dr. Raaj Mehta, a lecturer at Harvard Medical School and a physician at Massachusetts General Hospital.

As part of the study, scientists analyzed data from more than 30,000 women and found that eating one medium orange daily could reduce the risk of developing depression by 20%. Interestingly, a similar effect was not observed in people who regularly consumed other fruits, such as apples or bananas.

Scientists suggest that the positive effect of citrus fruits may be due to the activity of the bacteria Faecalibacterium prausnitzii, which is present in the human intestine. This bacterium has powerful anti-inflammatory properties and promotes the production of neurotransmitters, in particular serotonin and dopamine. These chemicals play an important role in regulating a person’s mood and mental state.

In view of this, scientists note that nutrition is only one component of mental health. Physical activity is also an important factor. Both moderate and intense physical exercise help reduce the risk of developing depression and dementia, improving the overall psycho-emotional state.

However, as the researchers note, the effectiveness of such methods may vary depending on the individual characteristics of the body. Therefore, it is important to consider these factors, along with proper nutrition, exercise, and a conscious approach to medication, to maintain mental health. Including citrus fruits in the diet can be an important component of this comprehensive approach.
