A new study suggests that following a Mediterranean diet may help reduce the risk of depression in people with rheumatoid arthritis. Researchers found that individuals with higher adherence to this diet had significantly lower odds of experiencing depression. The findings were published in the Journal of Health, Population and Nutrition.
Study Overview
The study, conducted by researchers at Honghui Hospital, Xi’an Jiaotong University in China, analyzed data from 1,148 adults with rheumatoid arthritis. Participants reported their dietary habits through 24-hour recall interviews, allowing researchers to assess their adherence to the Mediterranean diet.
Depression was present in about 25% of participants. However, those who closely followed the Mediterranean diet had a 47% lower risk of depression compared to those who did not adhere to the diet as strictly (odds ratio: 0.53).
Key Diet Components That Reduced Depression Risk
Two specific food groups stood out as particularly beneficial:
- Vegetables: Higher vegetable intake was linked to a 46% lower risk of depression (odds ratio: 0.54).
- Cereals (whole grains): Greater consumption of cereals was associated with a 37% lower risk of depression(odds ratio: 0.63).
These findings suggest that plant-based components of the Mediterranean diet may play a role in improving mental well-being.
Why Might the Mediterranean Diet Help?
The Mediterranean diet is rich in anti-inflammatory and antioxidant foods, including vegetables, fruits, whole grains, nuts, and olive oil. Since both rheumatoid arthritis and depression involve inflammation, researchers believe that the diet’s anti-inflammatory properties may help improve both conditions.
Additionally, the diet supports gut health, which is increasingly linked to mental health. A well-balanced gut microbiome can influence mood regulation and reduce symptoms of depression.
More Research Needed
While the study provides strong evidence of a link between diet and mental health in rheumatoid arthritis patients, the researchers caution that more rigorous studies are needed to determine causal relationships.
Future research should explore whether following a Mediterranean diet over time can directly prevent or reduce depression in people with chronic conditions.
Takeaway
For people with rheumatoid arthritis, adopting a Mediterranean diet may offer mental health benefits in addition to its well-known physical health advantages. Eating more vegetables and whole grains, along with other Mediterranean diet staples, could be a simple and natural way to support both joint and emotional well-being.
