The neutropenic diet is an eating plan for people with weakened immune systems, such as those undergoing cancer treatment or living with HIV/AIDS, or those who have had an organ transplant. The aim of the diet is to reduce the risk of foodborne illnesses by eliminating raw or uncooked foods, including vegetables, fruits, meat, and unpasteurized dairy products, which may contain harmful bacteria. While the effectiveness of the diet has been debated, with some studies showing no significant difference in infection rates between those on the diet and those who are not, it is still recommended by some doctors for individuals with specific health needs and goals.

Cancer patients
A neutropenic diet is for people with weakened immune systems, including cancer patients undergoing treatments such as chemotherapy, radiation therapy, and immunotherapy. These treatments can affect how well the immune system works, leading to leukopenia, or a lower-than-normal white blood cell count, which increases the risk of infection.
The neutropenic diet is designed to reduce the risk of infection from foodborne bacteria by eliminating raw or uncooked vegetables, fruits, meat, eggs, and unpasteurized dairy products. It also includes well-cooked foods and commercially packaged foods. People following this diet should also be cautious of water, only drinking water that has been distilled, filtered, or boiled for at least one minute.
The diet is typically followed before and after certain types of chemotherapy and other cancer treatments. A blood test called an absolute neutrophil count (ANC) can help determine the body's ability to fight off infection, and when the ANC is less than 500 cells/mm3, the patient is often instructed to follow a neutropenic diet.
It is important to note that there is a lack of consensus on the effectiveness of the neutropenic diet in reducing exposure to bacteria in foods. Some experts emphasize the importance of safe food handling and preparation practices over restricting specific food groups. Cancer patients should discuss any dietary changes with their healthcare providers and follow safe food practices and precautions when preparing and eating meals.

Neutropenia
People with neutropenia may be advised to follow a neutropenic diet, which is designed to reduce the risk of foodborne illnesses in immunocompromised patients. The diet involves choosing foods and preparing them in a specific way to lower the risk of harmful microbes and bacteria. It is also known as a low-microbial diet.
The neutropenic diet has been recommended for people with weakened immune systems, including those undergoing cancer treatment, stem cell transplants, organ transplants, or HIV/AIDS treatment. The diet typically involves eliminating raw or uncooked vegetables, fruits, meat, and unpasteurized dairy products. It is important to note that the effectiveness of the neutropenic diet in preventing infection has been debated, with some studies failing to find significant differences between groups following the diet and those who are not.
Safe food practices and precautions are essential for those following a neutropenic diet. This includes thoroughly washing fresh fruits and vegetables, or opting for cooked, canned, or frozen produce. It is also recommended to avoid raw or undercooked meat, fish, and eggs, instead cooking these foods thoroughly. When it comes to dairy, it is important to avoid unpasteurized milk and yogurt, as well as soft cheeses, and opt for pasteurized alternatives. For beverages, it is crucial to ensure that water is distilled, filtered, or boiled to prevent the consumption of harmful bacteria.

Immunocompromised patients
The neutropenic diet involves choosing foods that are less likely to contain harmful bacteria and preparing, cooking, and storing them in a specific way to further reduce the risk of contamination. For example, it is recommended to avoid raw or undercooked meat, fish, and eggs, as well as unpasteurized dairy products, and to cook meat until it is "well-done". It is also important to thoroughly wash fresh fruits and vegetables before consumption, or opt for cooked, canned, or frozen produce.
The diet is often recommended for people with cancer, particularly those undergoing chemotherapy, as their immune systems may be weakened by the treatment, making them more susceptible to infections. It is also suggested for patients with neutropenia, a blood condition characterised by a low count of white blood cells, which are crucial for fighting off infections. Additionally, people who have had an organ transplant or are being treated for HIV/AIDS may need to follow this diet.
While the effectiveness of the neutropenic diet has been debated, with some studies failing to find significant differences in infection rates between those on the diet and those who are not, it is still prescribed in many institutions. However, it is important to note that dietary changes should always be discussed with a healthcare professional, as individual health needs may vary.
Other precautions immunocompromised patients may need to take include avoiding close contact with sick individuals, even family members, and avoiding public swimming pools and hot tubs due to the potential presence of pathogens. Maintaining proper sleep hygiene is also important, as a lack of sleep can further compromise the immune system.

Food preparation
The neutropenic diet is an eating plan for people with weakened immune systems, often recommended before and after certain types of chemotherapy and other cancer treatments. It involves preparing, cooking, and storing food in a specific way to reduce the risk of foodborne illnesses. Here are some detailed instructions for food preparation while on the neutropenic diet:
Wash Fruits and Vegetables Thoroughly:
Wash fresh fruits and vegetables before eating or peeling. Thick-skinned fruits like bananas, oranges, and grapefruit should be washed and peeled before consumption. Cooked fruits and vegetables are safe to eat without peeling.
Cook Meat, Poultry, Fish, and Eggs Thoroughly:
Avoid raw or undercooked meat, fish, and eggs. Meat, poultry, and fish should be cooked until well-done. All eggs should be thoroughly cooked with no runny yolks. Avoid deli meats, and opt for vacuum-packed lunch meats instead of freshly sliced meats.
Choose Pasteurized Dairy Products:
Consume only pasteurized milk and dairy products such as cheese, yogurt, and sour cream. Avoid unpasteurized milk, yogurt with live or active cultures, soft cheeses (Brie, feta), aged cheeses, and cheeses with uncooked vegetables.
Avoid Raw Starches:
Avoid consuming raw starches such as bread with raw nuts, uncooked pasta, raw oats, and raw grains. Cooked starches like bread, pasta, chips, pancakes, and cereal are safe to eat.
Be Cautious with Beverages:
Drink pasteurized milk and avoid unpasteurized fruit juices and cider. Well water is safe if it has been filtered, distilled, boiled for at least one minute, or undergone reverse osmosis.
Safe Food Handling and Storage:
Wash your hands before, during, and after food preparation and eating. Avoid cross-contamination by using separate cutting boards and utensils for raw and cooked foods. Do not place hot food directly into the refrigerator, but instead, place it in shallow pans or dishes to cool quickly. Label leftovers with a "use by" date and dispose of uneaten food within 48 hours. Keep cold foods at or below 40°F and hot foods above 140°F.

Water safety
When it comes to water consumption as part of a neutropenic diet, there are a few guidelines to follow to ensure water safety:
- Bottled water is generally considered safe, especially if it has been distilled, filtered, or undergone reverse osmosis.
- Tap water is also safe to consume in most cases, but it is essential to check with your local water authority or healthcare provider to ensure that it meets safe drinking standards.
- Well water should be avoided unless it has been properly filtered, distilled, or boiled for at least one minute. Boiling helps kill harmful bacteria and microorganisms that may be present in the water.
- It is crucial to avoid drinking water that may be contaminated. Look out for cloudy or discoloured water, and always ensure your water source is secure and protected.
- When travelling or unsure about the water quality, opt for bottled water or consider investing in a portable water filter or purification tablets to ensure safe drinking water.
- Proper hydration is essential, especially for those with weakened immune systems. Ensure you are drinking enough water throughout the day and during meals.
In addition to water safety, the neutropenic diet also recommends specific food preparation, cooking, and storage techniques to reduce the risk of bacterial infections. It is always best to consult with a healthcare professional or a dietitian before starting any new diet, especially if you have specific health concerns or conditions.
