The NUTRIENT study evaluates the effects diet among participants who have been diagnosed with an MPN. Studies indicate that a healthy diet may reduce inflammation in the body.  For individuals who have an MPN, this inflammation drives the disease course. Our hope is that altering the balance of inflammation in the body may help individuals to feel better and ultimately change the course of the disease by reducing the risk of blood clots, abnormal blood counts, and spleen size changes.


The first step of the NUTRIENT study is to determine whether MPN patients can follow a healthy diet with nutritionist counseling and education. During this study, participants will be asked to follow one of two healthy diets. The study lasts a total of 15 weeks and includes nutritionist counseling, and diet education materials.

If you are interested in participating, keep these things in mind:

  • Because this study requires in person nutritionist counseling and blood draws you must be willing to travel to Irvine, California approximately once monthly for 15 weeks
  • You must be at least 18 years old and have a myeloproliferative neoplasm (polycythemia vera, essential thrombocythemia, or myelofibrosis)
  • You will be asked to fill out online surveys about what you are eating and your symptoms approximately every two weeks for 15 weeks
  • You will be asked to have blood drawn and provide a stool and urine sample approximately every month for 3.5 months
