Brief Summary:
Myeloproliferative Neoplasm (MPN) is a chronic blood cancer without cure. The major clinical issues in MPN are 1) an increased risk of blood clots 2) symptoms thought to be driven by chronic inflammation which in some cases can be debilitating and 3) progression to acute leukemia. The current management of MPN focuses on preventing blood clots and relieving symptoms. However, treatments that reduce symptoms such as JAK inhibitors are limited to late stage MPN patients and have significant side effects including immunosuppression, reduction in platelets, and increased risk of skin cancer. Therefore, low risk interventions are sorely needed for MPN patients that can reduce symptoms. Diet represents a low risk way to reduce inflammation, specifically a Mediterranean diet has been found to reduce inflammation in cardiovascular disease. There has been a recently completed clinical trial that demonstrated MPN patients can adopt a Mediterranean diet if given dietician counseling and curriculum. However, in order to reach a larger group of people a fully remotely administered study is necessary. This is a feasibility study to determine.
