There are many products that contain uncooked eggs, and these products are among the types of food prohibited for cancer patients, such as salad dressings and mayonnaise.

Unpasteurized dairy products and moldy cheeses

Unpasteurized milk and dairy products should be avoided, as should moldy cheeses, due to the inability of the immune system in cancer patients to deal with cheese mold normally.

Some vegetables and fruits

Some types of vegetables and fruits may be difficult to clean, such as lettuce, strawberries, and raspberries, so it is preferable to avoid eating them in case of neutropenia.

Nutrition during chemotherapy

When it comes to feeding cancer patients during chemotherapy, foods that are light in flavor, easy on the stomach, and rich in nutrients are the preferred options. Here are some foods that are beneficial for Nutrition for cancer patients:

Oats from nutrition during cancer treatment

Oats provide many nutrients that help the body during chemotherapy, as oats contain large amounts of carbohydrates, protein, and antioxidants, in addition to healthy fats. It also helps in regulating the intestines because it contains beta-glucan, a type of soluble fiber that feeds the healthy bacteria in the intestines.

Oatmeal’s neutral flavor and creamy texture are especially useful for reducing common side effects of chemotherapy such as dry mouth or mouth ulcers. To make a simple oatmeal dish, oats can be soaked in milk and refrigerated overnight. And in the morning you can add fresh berries, honey, and nuts.

Avocado from nutrition in cancer

Avocado is a suitable food in case of anorexia, as it contains calories and essential nutrients for the diet. It is a smart choice for people suffering from dry mouth, constipation, mouth ulcers, or losing weight, as it is filling, light and versatile at the same time. To eat, it can be mashed and spread on a piece of toast, or cut into slices and placed on top of a salad or soup.

Eggs is one of oncology nutrition

General fatigue is a common side effect of chemotherapy, and nutritional advice for better chemotherapy results urges eating eggs to combat fatigue due to their supply of protein and fat (one medium-sized egg contains approximately 6g of protein and 4g of fat). While fat provides the body with energy, protein helps maintain and build muscle mass, which is important during chemotherapy. Eggs can be prepared boiled or fried, as the soft texture of eggs makes them suitable if the patient suffers from mouth ulcers.

Eat Gravy

Taste changes are normal during chemotherapy, and in some cases, patients experience a change in the taste of water as well. It is a healthy alternative to keep your body hydrated and prevent dehydration in these situations. This boiling process makes the broth rich in sodium, potassium, chloride, and calcium which help the body perform its functions well. And eating broth can be useful in the event of loss of salt through vomiting due to chemicals, diarrhea, or heavy sweating.

It can be prepared by boiling water with vegetables and herbs, and poultry or meat can be added in addition to the bones. And to add more nutrients, especially in the case of dry mouth or decreased appetite, a spoonful of flavorless protein, such as collagen powder, can be consumed.

Almonds and nuts

Doctors and nutritionists encourage eating nuts a lot, such as almonds and cashews, to get better results from chemotherapy. This is because they can be eaten easily and at any time, in addition to containing abundant amounts of protein, healthy fats, vitamins, and minerals.

Nuts contain powerful antioxidants that help fight free radicals that damage cells. Nuts can be added to oatmeal or other dishes. In the case of a dry mouth, it may be difficult to eat nuts. In such cases, one can choose nut butter instead.

Pumpkin seeds

Pumpkin seeds are a healthy option to eat as a snack for cancer patients between treatment appointments. They are rich in fats, protein, and antioxidants like vitamin E, which can help fight inflammation.

It should be noted that some treatments, such as a blood transfusion, may increase the risk of high iron in the blood, and in such a case, one should be careful not to eat pumpkin seeds and other iron-rich foods.

Eat Broccoli

Broccoli contains a large amount of vitamin C, which is essential for the immune system. Research has shown that sulforaphane in broccoli helps reduce inflammation and protects cells from damage, which is especially significant when undergoing chemotherapy.

Broccoli can be cooked or grilled with olive oil and a bit of salt. Lemon juice can be squeezed over it if you suffer from changes in your sense of taste.

Fish from diet during and after cancer treatment

It is healthy to eat two servings of fish per week during the chemotherapy period, as it contains protein and omega-3 fatty acids. With regard to the nutrition of cancer patients during the period of chemotherapy, it is extremely crucial that their diet includes omega-3 acids, which are characterized by their anti-inflammatory properties.

In addition, eating foods rich in protein and fats, such as fish, helps avoid weight loss during chemotherapy.
