Reacción a "A small pilot study examines the reduction in the consumption of ultra-processed foods among patients with depression"

This study provides new insights into the possible link between the consumption of ultra-processed foods and mental health, in this case amongst people with depression. Unlike previous studies, which have mainly observed an association between higher consumption of ultra-processed foods and an increased risk of depression, this study assesses what happens when consumption is reduced in people who already have this disorder.

The results show that during the period in which consumption of ultra-processed foods was reduced, participants reported lower scores for symptoms of depression and anxiety than during the period in which they followed their usual diet. Furthermore, the intervention was well received by the participants, although reducing their intake of these foods to such a significant extent was not particularly easy.

The study involved 20 people with depression and a high intake of ultra-processed foods. Throughout the study, participants alternated between their usual diet and a diet in which the consumption of ultra-processed foods was considerably reduced, whilst keeping other factors such as medication, therapy, exercise and sleep unchanged.
These results are interesting because they suggest that diet may play a complementary role in the management of depression. However, they should be interpreted with caution. This is a pilot study with a very small sample size, and changes in symptoms of depression and anxiety were not the primary objective of the study. Furthermore, it does not allow us to determine whether the results are specifically due to the reduction in ultra-processed foods or to other associated dietary changes, such as alterations in calorie, fat or sugar intake. Larger studies will therefore be needed to confirm these findings and gain a better understanding of the mechanisms involved.
