Polycythemia vera (PV) is a rare, chronic blood disorder that causes the bone marrow to produce too many red blood cells. This thickens the blood, slowing its flow and increasing the risk of blood clots, heart attacks, strokes, and pulmonary embolisms. In its final stages, PV can lead to myelofibrosis, a type of blood cancer where the bone marrow is replaced by scar tissue. While PV cannot be reversed or managed with any specific diet, certain dietary habits can minimize complications and improve overall health. For instance, a Mediterranean-style diet, rich in fruits, vegetables, nuts, olive oil, and whole grains, can help prevent heart disease, a common complication of PV.

What You'll Learn
A Mediterranean-style diet may help prevent heart complications
Polycythemia vera is a rare, chronic blood disorder that causes the bone marrow to produce too many red blood cells. Over time, this can lead to blood cancer. The bone marrow damage associated with the disease can also cause scar tissue to form, increasing the risk of bone fractures. The condition can cause serious complications, including blood clots, stroke, and heart attack.
While dietary changes cannot reverse or manage the condition, they can help to prolong good health and minimise complications. People with polycythemia vera should avoid foods containing purines, oxalates, and high levels of fat or sugar, as these can exacerbate serious complications. It is also important to ensure adequate intake of calcium and vitamin D, as these minerals help to build and maintain bone strength.
A Mediterranean-style diet may be beneficial for people with polycythemia vera as it can help to prevent heart complications. This style of eating emphasises vegetables, fruits, whole grains, beans, legumes, and low-fat or fat-free dairy products. It includes fish, poultry, non-tropical vegetable oils, and nuts, while limiting added sugars, sugary beverages, sodium, highly processed foods, refined carbohydrates, saturated fats, and fatty or processed meats.
The Mediterranean diet has been consistently ranked as one of the best diets for overall health. It has been shown to reduce the risk of heart disease, stroke, and another heart attack. The diet is rich in virgin olive oil, which may help to remove excess cholesterol from arteries and keep blood vessels open. Additionally, it provides most of the key diet changes recommended for heart health, including increasing unsaturated fats and reducing saturated fats.
By adopting a Mediterranean-style diet, individuals with polycythemia vera can not only improve their overall health but also help to prevent heart-related complications associated with the condition. This dietary approach can be maintained consistently, regardless of the severity of polycythemia vera, and can be a beneficial lifelong strategy to manage the condition.

Calcium and vitamin D can help to build and maintain bone strength
Polycythemia vera is a rare, chronic blood disorder that causes the bone marrow to produce too many red blood cells. This thickens the blood, slowing its flow and increasing the risk of blood clots, heart attacks, and strokes. In some cases, it can lead to other blood diseases, including a disorder in which scar tissue replaces bone marrow. While dietary changes cannot cure or manage the condition, they can help prolong good health.
Calcium and vitamin D are essential to building strong, dense bones, both during youth and as one ages. Calcium is a mineral that is necessary for life, and vitamin D helps the body absorb calcium. Together, they protect bones and prevent further bone loss.
Milk and dairy products are the best sources of calcium as they contain a form that the body can easily absorb. Yogurt, cheese, and buttermilk are good options, and adults should opt for fat-free or low-fat versions. Vitamin D is a fat-soluble vitamin that plays an important role in protecting bones and supporting muscles. The body can produce vitamin D through sun exposure, but many people do not get enough. Fatty fish and fortified foods like milk, yogurt, and cereal are good sources of vitamin D.
If you have polycythemia vera, it is important to get enough calcium and vitamin D to help prevent bone fractures associated with bone marrow damage. However, it is also crucial to avoid foods high in oxalate, such as beans, berries, and leafy greens, as they can worsen complications and increase the risk of kidney stones.
In summary, while diet alone cannot manage polycythemia vera, ensuring adequate calcium and vitamin D intake can help build and maintain bone strength, reducing the risk of fractures associated with the condition.

Avoid foods containing purines, oxalates, high fat, and sugar
Polycythemia vera is a chronic blood disorder in which the body makes too many red blood cells, causing symptoms and complications such as fatigue, ulcers, kidney stones, blood clots, and cancer. While the condition is not caused by dietary factors and cannot be managed with a specific diet, certain dietary habits can increase the risk of these complications.
Purines
Purines are prevalent in nature and are a normal part of the diet, but consuming too many can cause a buildup of uric acid in the body. If uric acid remains in the body for too long, it can crystallize and cause health risks. Organ meats, beer, and sardines are examples of foods with high purine levels. If you are predisposed to hyperuricemia or other purine-related health complications, such as gout, you may need to moderate your purine intake or seek alternative food options.
Oxalates
Oxalates are naturally present in many foods, but high levels can contribute to the formation of kidney stones. People with polycythemia vera are already at an increased risk of developing kidney stones, so it is generally recommended to avoid foods that are high in oxalates. These include beans, berries, and leafy greens, as well as avocados, oranges, grapefruit, and raspberries.
High Fat
Consuming large amounts of saturated or trans fats is generally considered unhealthy. Too much saturated fat can raise LDL cholesterol levels, negatively impacting your health. Fatty meats, bacon, butter, cream, fried potatoes, and fast food are examples of foods high in saturated fats. To reduce saturated fat intake, opt for lean meats, remove the skin from poultry, choose low-fat dairy options, and use unsaturated fats like olive oil and canola oil instead of butter.
Sugar
Sugar is commonly found in soft drinks, juices, alcoholic beverages, and processed foods. While sugar itself is not inherently harmful, excessive consumption can contribute to weight gain, increased blood cholesterol levels, and a higher risk of heart disease. It is important to monitor your intake of added sugars and prioritize natural sources, such as whole fruits, to satisfy your sweet tooth.

Include complex carbohydrates and lean protein in your diet
Polycythemia vera is a rare and chronic blood disorder that causes the bone marrow to make too many red blood cells. Over time, the condition may progress to blood cancer, and the associated bone marrow damage can increase the risk of bone fractures. While the condition is not caused by dietary factors and cannot be managed with a specific diet, certain dietary habits can minimise complications and improve overall health.
One recommended dietary habit is to include complex carbohydrates and lean protein in your diet. Complex carbohydrates are the body's main source of energy and can be found in fruits, vegetables, whole grains, breads, cereals, pasta, rice, beans, peas, and starchy vegetables such as potatoes, green peas, and corn. Whole grains are considered good carbohydrates, while processed grains, such as white flour or white rice, are considered bad due to their low fibre and nutrient content.
Lean proteins are also important for providing the body with energy and helping to build and repair tissues. Examples of lean proteins include seafood, poultry, eggs, beans, peas, soy products, and unsalted nuts and seeds. Plant-based sources of protein tend to be lower in fat and cholesterol and provide additional fibre and nutrients.
By including a variety of these foods in your diet, you can ensure that you are getting sufficient complex carbohydrates and lean protein to support your overall health and energy levels while managing polycythemia vera.

Iron-rich foods can help prevent iron deficiency
Polycythemia vera is a chronic blood disorder in which the bone marrow makes too many red blood cells. This condition can cause many symptoms and complications, including blood clots, increased blood thickness, decreased blood flow, and atypical platelets. Over time, it may progress to blood cancer and cause bone marrow damage, increasing the risk of bone fractures.
While polycythemia vera is not caused by dietary factors and cannot be managed with a specific diet, certain dietary habits can help minimize complications and improve overall health. It is recommended to reduce the intake of foods containing purines, oxalates, and those high in fat or sugar, as they can exacerbate serious complications. Instead, it is beneficial to include foods that provide complex carbohydrates and lean protein, such as fruits, vegetables, whole grains, poultry, eggs, tofu, and low-fat dairy.
In addition to managing polycythemia vera, it is important to prevent iron deficiency, as it can lead to anemia and fatigue. Iron is a mineral that serves important functions in the body, and a deficiency can occur if your intake is too low. Iron-rich foods include meat, especially red meat, liver, and ground beef; seafood, including shellfish, tuna, and oysters; and eggs. For non-meat eaters, plant-based sources of iron are also available, such as legumes, nuts, seeds, and vegetables like spinach, broccoli, and leafy greens. Fortified foods, such as tofu, grains, bread, and cereal, are also good sources of iron.
To enhance iron absorption, pair iron-rich foods with vitamin C-rich foods like citrus juices or other sources of vitamin C. This helps your body better absorb dietary iron. Additionally, aim to include a source of protein with each meal, as protein can help you meet your daily iron needs.

Frequently asked questions
Polycythemia Vera (PV) is a type of blood cancer that causes your bone marrow to produce too many red blood cells. It is a chronic blood disorder that can cause serious complications such as blood clots, heart attacks, strokes, and pulmonary embolisms.
In the advanced stages of PV, mutated blood cells can crowd out normal cells in the bone marrow, replacing them with scar tissue. This is known as the "spent phase" of the disease, where the bone marrow can no longer produce healthy blood cells, leading to anemia and an increased risk of hemorrhage.
While there is no specific diet to reverse or manage PV, dietary changes can help prolong good health and minimize complications. A Mediterranean-style diet, rich in fruits, vegetables, nuts, olive oil, and whole grains, is recommended to help prevent heart disease and improve overall well-being.
Foods containing purines, oxalates, high fat, or sugar should be avoided as they can exacerbate complications. Additionally, due to an increased risk of kidney stones, it is recommended to limit foods high in oxalates, such as beans, berries, and leafy greens.
Many people with PV do not notice any symptoms. However, some common symptoms include headache, dizziness, tiredness, blurred vision, itchiness after a warm bath or shower, numbness or tingling in the extremities, and a feeling of fullness after eating.
