The Mediterranean diet can be a healthy choice for those with psoriasis.
With results of previous studies and these findings, we should not hesitate to advise people with psoriasis to consider a healthy eating plan such as the MedDiet.
“The Mediterranean diet has been shown to reduce chronic inflammation and have a positive effect on the risk of metabolic syndrome and cardiovascular events,” wrote the authors. Because psoriasis is a chronic inflammatory condition, they theorized the diet would have a beneficial effect on it.
Psoriasis affects between 1 to 3 percent of the population. It’s characterized by itchy, red and scaly patches of skin. The condition can be painful and lead to joint problems, thus impairing the ability to perform everyday activities. As psoriasis has no cure, the goal of treatment is to manage symptoms.
The research published in JAMA Dermatology involved an analysis of data from the NutriNet-Santé program, an ongoing observational study launched in France in 2009.
The database included more than 35,000 participants of a mean age of 47.5 years.
Based on answers from a psoriasis questionnaire, the individuals were categorized into three groups: psoriasis-free, non-severe psoriasis and severe psoriasis.
To measure adherence to the MedDiet, dietary data was used to calculate MEDI-LITE scores, which range from 0 for no adherence to 18 for optimal adherence. In addition, information was collected on health and lifestyle factors such as gender, age, body mass index (BMI), smoking habits, cardiovascular disease, physical activity and depression symptoms.
Results showed that 10 percent of the participants had psoriasis, with approximately one-fourth of the cases being severe. A significant inverse relationship was found between the MEDI-LITE scores and severe psoriasis, which meant the higher the adherence to the MedDiet, the lower was the risk.
