The wrong kind of food linked to increased depression risk, major study finds
(NaturalHealth365) Technology and social isolation are frequently cited as major factors in the rising depression epidemic both in the United States and around the world. While many people do feel increasingly disconnected from their communities, the surge in depression cannot be solely attributed to these tech-driven issues.
Recent research published in Clinical Nutrition points to another significant factor: the consumption of ultra-processed foods. With an estimated 280 million people globally experiencing depression, it’s clear that multiple factors contribute to this widespread issue.
Research reveals link between ultra-processed foods and depression
Recent research highlights a significant connection between the consumption of ultra-processed foods and an increased risk of depression. While this study focused on Brazilian residents, it’s worth noting that Brazilians actually consume fewer ultra-processed foods on average than people in the United States, the United Kingdom, and other developed nations.
The study, part of the “NutriNet Brasil” initiative, aimed to investigate chronic diseases and dietary patterns among Brazilians aged 18 and older. Participants completed online questionnaires on their health and dietary habits, initially enrolling in the winter of 2020.
The researchers used Nova24h, an innovative online dietary recall tool to assess dietary intake. This technology categorizes foods based on their level of processing and monitors consumption patterns at six and twelve-month intervals.
How processed foods might be affecting your mood
A Patient Health Questionnaire was employed at the 14-month mark to evaluate symptoms of depression. Participants without a previous depression diagnosis who scored in the depressive range were assessed further with additional questionnaires every six months. This ongoing analysis aimed to track changes in depression symptoms over time.
The data analysis uncovered a strong link between the consumption of highly processed foods and the onset of depression. Even after adjusting for factors like diet quality, lifestyle, and demographics, the study found that increased consumption of highly processed foods was associated with a higher risk of developing depression. Specifically, the risk increased by 42% for those consuming higher levels of processed foods compared to those with the lowest intake. Additionally, for every 10% increase in highly processed food consumption, there was a corresponding 10% rise in depression risk.
