Many recent studies have highlighted the health benefits that a plant based diet can bring. Now, a new review explains just why it can be helpful for people living with rheumatoid arthritis.
Rheumatoid arthritis — a chronic autoimmune condition that causes pain and stiffness in the joints — has a prevalence of
The condition can become so debilitating as to stop people from continuing in full time work. As the WHO also note, within only 10 years from disease onset, at least 50% of individuals with rheumatoid arthritis in high income countries become "unable to hold down a full time job."
Doctors usually prescribe a range of drugs and lifestyle adjustments to help people manage their rheumatoid arthritis and make disability less likely. Management
Now, a new review appearing in the journal Frontiers in Nutrition shows that following a plant based diet can be a useful intervention when it comes to coping with this condition, as it triggers some helpful biological changes.
'Symptoms may improve or even disappear'
The review — conducted by specialists from the Physicians Committee for Responsible Medicine in Washington, DC — looked at recent studies that observed the impact of diet on biological mechanisms that are important in rheumatoid arthritis.
It concluded that plant based diets lead to specific changes that can help relieve the symptoms of this condition.
One key way in which plant based diets can be helpful is by reducing levels of inflammation. The review authors cite a
The team also notes that additional research has found an association between adherence to diets high in fat and processed meat and a rise in markers of inflammation. One of these markers is C-reactive protein, a protein present in the blood, and one which reacts to inflammation.
On the other hand, following plant based diets or diets that have a high content of fiber has an association with lower levels of C-reactive protein.
Another study that the review looked at was a
People with rheumatoid arthritis can also benefit from losing extra weight. According to evidence from a
The review authors explain that vegetarian and vegan diets appear to help people lose weight, more so than any other diet types.
Finally, the researchers explain that plant based diets also seem to promote a healthy gut environment, since many of these diets are high in fiber, which, as studies have shown,
Specifically, plant based diets seem to increase bacterial diversity in the gut, which could help people with rheumatoid arthritis, precisely because they tend to lack bacterial diversity.
The investigators who conducted the review suggest there is a need for further research into the benefits that plant based diets may afford to people with inflammatory autoimmune conditions, as well as their underlying mechanisms.
However, they note that, so far, the emerging evidence suggests that eating more fruits, vegetables, whole grains, and legumes could make a real difference for people with rheumatoid arthritis.
"A plant based diet comprised of fruits, vegetables, grains, and legumes may be tremendously helpful for those with rheumatoid arthritis. This study offers hope that with a simple menu change, joint pain, swelling, and other painful symptoms may improve or even disappear."
