Quick Navigation
If you're going through chemotherapy, you already know: nausea can turn every meal into a challenge. What you eat—and just as importantly, what you avoid—can make a real difference in how you feel.
But with so much conflicting advice out there, it's hard to know where to start. Should you force yourself to eat? Which foods actually help? And why does everything suddenly taste like metal?
We created this guide to cut through the confusion. Below, you'll find research-backed foods that help reduce nausea, the ones that typically make it worse, and practical strategies you can implement today.
Why Chemo Causes Nausea (and Why Food Matters)
Chemotherapy drugs target rapidly dividing cells—including cancer cells, but also the cells lining your digestive tract. This disruption triggers nausea, vomiting, taste changes, and appetite loss.[1]
The good news? Strategic food choices can help:
- Gentle foods are easier on your compromised stomach lining
- Bland options don't trigger additional nausea
- Cold or room-temperature foods reduce triggering smells
- Ginger and other natural remedies provide fast-acting relief
- Proper hydration prevents the dehydration that worsens nausea
Let's break down exactly what helps—and what doesn't.
Foods That Help Chemo Nausea: What to Reach For
These foods are commonly recommended by oncology dietitians and frequently mentioned by patients as easier to tolerate during treatment:[2]
| Food Category | Examples | Why It Helps |
|---|---|---|
| Bland Carbohydrates | Crackers, toast, plain rice, oatmeal, pretzels, plain pasta | Easy to digest, absorb stomach acid, provide gentle energy without overwhelming your system |
| Cold Foods | Popsicles, smoothies, chilled fruit, yogurt, cottage cheese, cold sandwiches | Less aroma means fewer nausea triggers; soothing on irritated throat; provides hydration |
| Ginger-Based | Ginger tea, ginger ale (real ginger), ginger chews, crystallized ginger, ginger supplements | Natural anti-nausea properties backed by research; calms digestive system quickly[3] |
| Mild Protein | Chicken broth, scrambled eggs, tofu, plain chicken breast, protein shakes, Greek yogurt | Maintains strength and muscle mass without heavy digestion; provides sustained energy |
| Salty Snacks | Saltines, pretzels, broth, pickles, salted crackers | Replaces electrolytes lost through vomiting; settles stomach; easy to nibble |
| Mild Citrus | Lemon water, lemon popsicles, mild citrus fruits (if tolerated) | Cuts through metallic taste; refreshing; can stimulate appetite |
| Soft Fruits | Bananas, applesauce, canned peaches, watermelon, cantaloupe | Easy to digest, naturally sweet, provides vitamins and hydration |
Patient Insight: Keep a "nausea kit" by your bed with crackers, ginger chews, and room-temperature water. Having these items within reach when you wake up can prevent morning nausea before it starts.
Foods That Make Chemo Nausea Worse: What to Avoid
These foods are commonly reported as nausea triggers during chemotherapy. If you're struggling, try avoiding these temporarily:[4]
| Food Category | Examples | Why It Hurts |
|---|---|---|
| Fatty/Greasy Foods | Fried foods, pizza, burgers, heavy cream sauces, butter-heavy dishes, fast food | Slows digestion significantly; sits heavy in stomach; increases nausea |
| Spicy Foods | Hot peppers, curry, spicy sauces, heavily seasoned foods, hot sauce | Irritates already-sensitive digestive lining; increases stomach acid production |
| Strong-Smelling Foods | Fish, onions, garlic, strong cheeses, hot foods with strong aromas | Smell alone can trigger nausea reflex; overwhelming to sensitive senses |
| Very Sweet Foods | Candy, pastries, sugary drinks, desserts, sweetened cereals | Blood sugar spike followed by crash worsens nausea; can be cloying |
| Acidic Foods | Tomato sauce, orange juice, vinegar-heavy foods, citrus (for some) | Can irritate sensitive stomachs; increases acid reflux (though mild citrus helps some people) |
| Caffeine/Alcohol | Coffee, energy drinks, alcohol, strong tea | Dehydrating; can increase stomach acid; may interact with medications |
| Tough/Dry Foods | Tough meats, dry chicken, crusty bread without toppings | Difficult to swallow; requires too much chewing; can irritate throat |
Important Note: Everyone's body responds differently. Some people tolerate foods on the "avoid" list just fine. Keep a simple food journal to track what works for you. What triggers nausea one week might be fine the next—your tolerance will change throughout treatment.

When to Call Your Doctor
While nausea is common during chemotherapy, some symptoms require immediate medical attention:
- You can't keep down any food or liquids for 24+ hours
- You're vomiting blood or material that looks like coffee grounds
- You have severe abdominal pain
- You're showing signs of dehydration (dark urine, dizziness, extreme thirst, confusion)
- Your anti-nausea medications aren't working
- You're losing weight rapidly (more than 5% of body weight)
- You're too weak to perform basic daily activities
Don't wait. Your oncology team can adjust your anti-nausea medications, provide IV fluids, or refer you to an oncology dietitian. These resources exist to support you—use them.
You're Doing Your Best—And That's Enough
Going through chemotherapy is one of the hardest things anyone can face. Some days, just getting a few crackers down is a victory. Be gentle with yourself.
What works one day might not work the next, and that's completely normal. Keep experimenting, stay in touch with your care team, and remember: you're not alone in this journey.
