Processed Food and Depression: A Strong Link Revealed by Research

Consuming high amounts of ultra-processed food and drinks, particularly those containing artificial sweeteners, may increase the risk of developing depression in women, according to a study published in the journal JAMA Network Open. The study, which examined the diets of nearly 32,000 middle-aged female nurses, found that those who consumed over nine portions of ultra-processed food per day had a 50% higher risk of depression compared to those consuming four portions or less. The link between ultra-processed foods and depression is still not fully understood, but it is believed that chronic inflammation and changes in the gut microbiome caused by these foods may play a role. The study did not include men, but the researchers believe the findings may be applicable to both genders. Ultra-processed foods have also been associated with an increased risk of diabetes, cardiovascular disease, cancer, and dementia. To avoid ultra-processed foods, it is recommended to read nutrition panels and ingredient lists when purchasing food.
