Cancer treatment can change how food tastes or smells. Try our diet tips to help you get the nutrition your body needs.

Seven tips to manage appetite during cancer treatment

If you’ve recently been diagnosed with cancer, you may notice that your favorite foods no longer taste the same.

You might have a bitter or metallic taste in your mouth, or some flavors may seem too strong, too bland or just plain off.

These changes are common and can happen for several reasons:

The emotional stress of your diagnosis

Certain medications

Side effects from treatments like chemotherapy, immunotherapy and radiation

The cancer itself

“Changes in taste can feel discouraging, but they don’t have to derail your health,” says Jacob New, MD, a medical oncologist at Scripps Clinic Torrey Pines and Scripps Cancer Center. “We have strategies to help you find foods that work for you, so you get the nutrition you need to stay strong through treatment. With the right plan, it’s possible to keep your energy up, tolerate therapies more easily and support your recovery.”

Why food tastes different during cancer treatment

Changes in taste and smell are a frequent side effect of cancer treatment. And they’re usually temporary.

“Certain foods may now taste bitter, metallic, too sweet or salty — or not have much taste at all,” says Alison Meagher, a registered oncology dietitian at Scripps. “If your sense of smell is affected, this also may change the way food tastes.”

There are many simple ways to maintain a healthy diet during cancer treatment.

Skipping your favorite foods on treatment days, trying cold or bland options, or switching to liquid meals, like smoothies, can all help.

If you’re having trouble eating or drinking, be sure to talk to your care team. A registered dietitian can help you create a plan to get the calories and nutrients you need to stay strong.

“If you experience persistent loss of appetite or feel nauseated and can’t eat for more than a day, contact your care team,” says Meagher. “A registered dietitian can help you develop a diet plan to get the nutrients and calories you need.”
Seven tips for managing taste and smell changes

These tips can help offset temporary changes in appetite, taste and smell after a cancer diagnosis:
1. If food tastes bitter

Cooler, sweeter foods are often easier to tolerate.

Eat foods at room temperature or cold

Add natural sweeteners like honey, agave or fruit preserves

Try marinades with citrus, vinegars, mustard or teriyaki

Swap red meat for milder proteins like chicken, tofu, fish, eggs, nut butters or dairy
2. If food tastes metallic

Metallic taste is common with chemotherapy. Use plastic or bamboo utensils.

Avoid metal pots and pans

Skip canned foods and drinks

Rinse your mouth with water or a baking soda solution before meals
3. If food just tastes “off”

Stick with mild, comforting foods and cleanse your palate.

Chew sugar-free gum or suck on lemon drops or peppermints

Eat starchy foods like plain rice, pasta, bread or potatoes

Choose bland options like cheese, eggs, oatmeal, creamy soups or nut butters

Try breakfast foods — they’re often mid and easy to eat
4. If food tastes too sweet

Balance flavors by cutting sweetness and adding tangy flavors.

Replace sweet fruits with vegetables

Dilute juices and sweet drinks with water or ice

Add sour ingredients like lemon, lime or vinegar (avoid if you have mouth sores)
5. If food tastes too salty

Reduce saltiness with sweetness or low-sodium alternatives.

Sweeten foods slightly with honey, syrup or fruit preservatives

Choose no-salt added or low-sodium products

Avoid adding salt when cooking
6. If food tastes bland

Boost flavor and texture to make meals more enjoyable.

Use herbs and spices like basil, mint, cinnamon, garlic or chili powder

Add flavor with mustard, vinegar, citrus juice or pickled foods (if tolerated)

Try different textures — crispy, creamy, chewy — to make food more interesting

Chew slowly to enhance taste
7. If smells make you nauseated

Reduce exposure to strong food odors:

Eat foods cold or at room temperature

Sip soups through a straw or use covered cups

Have someone else cook or eat in a well-ventilated area

Avoid slow cookers

Avoid restaurants with strong smells
Making adjustments after cancer diagnosis

With the right guidance, eating during cancer treatment can become easier, more enjoyable and even empowering. Small changes, like trying new flavors or adjusting food textures or finding recipes that fit your needs, can make a big difference in how you feel each day and how you approach meals with confidence.
