Processed Foods May Ease Symptoms
A small study indicates that reducing the intake of ultra-processed foods (UPFs) may lead to lower depression and anxiety scores. Participants who followed a low-UPF diet showed improved mental health markers, though researchers note that larger studies are needed to confirm these findings.
Why it matters
If confirmed, these findings could provide a non-pharmacological dietary intervention to help manage symptoms of depression and anxiety.
There is no universally accepted definition of UPFs . However, a widely used classification system known as NOVA defines them as industrial formulations made primarily from substances extracted or derived from foods, often with additives not typically used in home cooking. Examples include soft drinks, packaged snacks, candy, sausages, hot dogs, and pastries.
Previous research has linked UPFs to an increased risk of depression, anxiety, eating disorders , and other mental health conditions. In the new study, participants reduced their UPF intake by more than 85% and had significantly lower depression scores across three standard measures while following the low-UPF diet.
This small study included 20 participants who:
The participants also had to agree not to change medications, therapy, exercise, or sleep during the study.
