There's no way around it—chemo has some nasty side effects. From nausea to diarrhea to constipation to foods just tasting weird in general, it can be hard to even think about eating. Keep reading to find out the best foods to eat, and 10 foods to avoid during chemo.

10 Foods to Avoid During Chemo Treatments


Foods to Avoid During Chemo:

1. Raw eggs

Raw eggs aren't generally recommended for consumption by anyone, but those with lowered immune systems are especially cautioned to avoid raw eggs and foods that contain raw eggs, such as raw cookie dough, homemade mayonnaise, hollandaise sauce, and Cesar salad dressing. Even cooked eggs with a runny yolk are a no go; stick to scrambled and hard boiled eggs only.


Foods to Avoid During Chemo:

2. Unwashed fruits/vegetables

DO eat lots of fruits and vegetables, but make sure you wash them first! Even pre-washed vegetables can still have nasty germs, bacteria, and dirt clinging onto them that can be problematic for those with lowered immune systems.

When eating out, avoid eating raw fruits and vegetables altogether; you do not know if they are clean, or if they have been cross contaminated. Do not eat at buffets and salad bars, and avoid ready-to-eat salads.


Foods to Avoid During Chemo:

3. Unpasteurized dairy

Unpasteurized dairy is dairy that has not been sterilized. It may be good for baby cows, but it contains bacteria that can be harmful for humans. Fortunately, most dairy products you can buy at the grocery store are pasteurized and safe to consume. Make sure the container has the word "Pasteurized" on it.

Keep in mind, however, that many dairy products can magnify the effects of nausea and constipation experienced by many cancer patients.


Foods to Avoid During Chemo:

4. Moldy cheeses

Cheeses with fungus and mold such as blue cheese, Camembert, brie, Stilton, Gorgonzola, feta cheese, goat cheese, and queso fresco have a lot of flavor, but they also have a lot of bacteria. While safe for most adults, these cheeses should be avoided by those undergoing chemotherapy treatments. Stick to cheddar, Swiss, mozzarella, cottage cheese, and cream cheese.


Foods to Avoid During Chemo:

5. Raw honey

Raw honey and local honey are touted for people with allergies, but they contain bacteria that can be harmful to those with lowered immune systems.


Foods to Avoid During Chemo:

6. Raw fish

Due to the bacteria in raw fish, you should avoid, sushi and raw oysters.


Foods to Avoid During Chemo:

7. Under-cooked Meat

Make sure all meat you consume is cooked through, especially hamburger meat and poultry. Also make sure to cook any lunch meats, deli meats, and hot dogs you may consume.


Foods to Avoid During Chemo:

8. Raw nuts and raw nut butter

Raw nuts contain—you guessed it—bacteria that can be harmful to those undergoing chemotherapy treatments. Additionally, raw nuts contains phytic acid, which can prevent the body from absorbing vital nutrients and vitamins.


Foods to Avoid During Chemo:

9. Greasy foods and fried foods:

Aside from being generally unhealthy, greasy and oily foods can worsen diarrhea and other side effects of chemo.


Foods to Avoid During Chemo:

10. Spicy foods

Like fried foods, spicy foods can make diarrhea worse.

More tips:

  • We recommend eating bland foods to start with to help prevent nausea. Slowly add more flavor to your foods.
  • Even if you are having a hard time eating, don't skip meals; an empty stomach will often make your side effects worse.
  • If you are having trouble keeping food down or don't have an appetite, try eating 6-8 small meals and snacks throughout the day.
  • Try using milk substitutes and lactose free milk, as they are easier on the stomach than regular milk.
  • Eat foods that you enjoy eating.
  • Don't eat "fat free" and "diet" foods, and don't worry about eating too many calories. No one likes gaining weight, but your health and recovery is the most important thing right now; your body needs the extra calories, fat, and energy to fight.
  • Another factor to keep in mind is who’s prepping your meals - restaurants and fast food could end up further compromising your immune system.
