Cancer management requires various lifestyle changes, besides adhering to a doctor-recommended treatment.
The most important changes are regarding nutrition.
Certain foods aid in the recovery process, while others should be avoided.
This post focuses on foods for cancer patients to avoid.
Continue reading to understand the significance of proper nutrition for cancer patients and discover which foods should be excluded from your daily menu.
Why should cancer patients adjust their diet?
Dietary modifications for cancer patients are essential to enhance resilience and manage the side effects of cancer treatment.
A proper diet helps cancer patients feel better, become stronger, lower the risk of infection, reduce inflammation, heal and recover faster, and maintain their weight.
As reported in the Annual Review of Nutrition, dietary intervention has been shown to reduce toxicity, enhance chemotherapy efficacy, and lower the risk of long-term complications in cancer patients.
A healthcare provider may recommend specific dietary adjustments for patients, or they may involve a nutritionist or dietitian in the process.
10 foods for cancer patients to avoid
Cancer patients need a nutrient-rich diet to keep their bodies strong. o optimize your diet, it’s crucial to avoid or limit the consumption of the following foods.
1. Raw seafood
Cancer patients, especially those undergoing chemotherapy, should avoid raw seafood. Raw or undercooked shellfish, like oysters, could carry the hepatitis A virus.
At the same time, raw fish is rich in mercury. Due to a weakened immune system, cancer patients should avoid these foods. Plus, there’s also the risk of cross-contamination with bacteria when raw meat is involved.
2. Unpasteurized dairy products
Unpasteurized dairy products, like raw yogurt or raw milk, may harbor bacteria that pose health risks.
Cancer patients, with compromised immunity, are more susceptible to health risks. Eating these foods could increase the risk of infection.
3. Raw eggs
Eggs are healthful and contribute to a well-balanced diet, being rich in nutrients and vitamins.
Cancer patients don’t need to avoid eating eggs entirely. However, you do need to avoid eating raw or lightly cooked eggs or any meal that contains them.
Why? Raw eggs contain Salmonella bacteria. These bacteria can cause infection, which is exactly what you need to prevent.
To sum up, you can keep eating eggs and foods containing them, but make sure they’re properly cooked. You also need to avoid adding eggs to smoothies. Many people do that, but they risk developing an infection.
4. Unwashed fruits and vegetables
Everyone should avoid eating unwashed produce, especially cancer patients. These fruits are full of dirt and also fertile ground for bacteria. Consumption of unwashed produce could lead to infection and sickness.
To avoid these problems, you should always wash fruits and vegetables. Do so even when they’re labeled “pre-washed.”
Pay extra attention to leafy greens, produce you grow yourself, and homegrown or store-bought fresh herbs such as thyme or basil.
Remember, you need to wash fruits or vegetables even if they have a peel that you won’t eat. If you don’t wash them, you are still at risk of infection because cutting them through brings dirt and bacteria from the outside to the inner portions of the produce.
5. Raw vegetable sprouts
Speaking of vegetables, cancer patients should avoid consuming raw sprouts. While they’re popular nowadays, raw vegetable sprouts increase the risk of contamination.
Some types of bacteria, such as E. coli, don’t come off that easily while washing. For that reason, the best thing you can do to prevent contamination and infection is to avoid raw vegetable sprouts entirely.
6. Foods with strong flavors
Cancer treatments such as chemotherapy and radiation have various adverse reactions, including nausea, vomiting, sores in the mouth, and sore throat.
In order to prevent irritation of the sores or worsen other side effects, the best thing to do is to avoid foods with strong flavors.
Ideally, you should avoid foods that are tart, acidic, sour, and spicy. Try not to eat them even if they’re among your favorite foods.
Instead, focus on more bland flavors and foods such as cream-based soups, milkshakes, pudding, and cooked or canned fruits and vegetables.
7. Raw honey
Cancer patients, like babies, shouldn’t eat honey. You see, raw honey may carry botulism toxin and could make you ill.
Consult your doctor or dietitian regarding the alternatives. After all, honey is beneficial for our health, and it could help people in many ways.
American Cancer Society recommends commercial, grade A, heat-treated honey instead of raw honey.
8. Undercooked meat
In the same way cancer patients should avoid raw seafood, they should also say no to undercooked meat.
This kind of meat may contain bacteria and viruses that cause foodborne illnesses. If you like eating your steak rare, you may want to stop doing so. Always make sure meat is properly and thoroughly cooked before eating.
9. Moldy cheese
Everyone loves cheese, and while there are plenty of options that are good for you, moldy cheese is not. You see, the mold responsible for the distinct taste and color of this cheese is a fungus.
While in healthy people, the organism is strong enough to tackle this fungus, cancer patients have weaker immunity. Their body isn’t strong enough to handle these tiny organisms that could cause infections. That’s why you need to strive and avoid moldy cheese.
10. Junk food
The reality is that junk food is bad for everyone. Not only is it low in nutrients, but it’s high in salt and bad fat content.
Salt is dehydrating, but as a cancer patient, you need to stay hydrated throughout the day. Additionally, junk foods have quite intense flavors that may contribute to your nausea. If you simply love junk food and have to eat it, make sure to do it in moderation.
Conclusion
Men and women with cancer need to modify their diet in order to improve strength and energy levels, reduce inflammation, and decrease the side effects of their treatments. Some foods may worsen a cancer patient’s health.
Ideally, cancer patients should avoid unwashed produce, raw meats, and foods with strong flavors. All these foods can either contribute to infections or worsen the side effects of cancer treatment.
Strive to focus on healthy foods that are prepared thoroughly and supply your body with a wide range of vitamins, minerals, and other nutrients. Adhere to the doctor’s or dietitian’s instructions regarding food intake during cancer treatment.
