What sounds okay today?

Tap whatever's hardest right now. These are simple things many people find easier to manage on treatment days — a starting point for tonight, not a treatment plan.

If nausea is the problem

Cold and bland foods tend to be easier on a queasy stomach — strong smells are often the trigger.

  • Dry toast, crackers, or plain bread
  • Clear broths or light soups
  • Ginger tea or ginger chews
  • Popsicles, sherbet, or gelatin
  • Room-temperature or cold foods
  • Sipping fluids slowly between meals

Tip: Cold foods give off less aroma than hot ones, which can help a lot when smells set off nausea. Try eating away from the kitchen if cooking smells bother you.

If nothing sounds good

Smaller, more frequent bites are often easier than sitting down to a full plate.

  • 5–6 small meals instead of 3 big ones
  • Smoothies with fruit, yogurt, or nut butter
  • Scrambled eggs
  • Full-fat yogurt or cottage cheese
  • Toast with nut butter or avocado
  • Soups with added beans or lentils for protein

Tip: It's okay to eat whatever stays down, even if it's the same thing a few days in a row. Getting calories and protein in matters more than variety right now.

If your mouth or throat is sore

Soft, smooth, and mild is the goal — anything acidic, spicy, or crunchy can sting.

  • Mashed potatoes
  • Oatmeal or cream of wheat
  • Smoothies or milkshakes
  • Scrambled eggs
  • Soft, well-cooked pasta
  • Avoid citrus, tomato, and rough crackers/chips

Tip: Letting hot food cool to warm or room temperature before eating can make a real difference if your mouth is tender.

If everything tastes metallic

A common chemo side effect — a few simple swaps can help.

  • Marinated chicken or fish
  • Fresh herbs (basil, mint, cilantro)
  • Tart foods like lemonade, if your mouth isn't sore
  • Plastic utensils instead of metal
  • Cold or room-temperature meals
  • Sucking on mints or chewing gum between bites

Tip: Red meat often tastes "off" first — chicken, fish, eggs, and beans are usually easier during this stretch.

If you're too tired to cook

This is a great time to lean on convenience — that's not a failure, it's a strategy.

  • Frozen meals prepped on a good day
  • Protein shakes or meal-replacement drinks
  • Hard-boiled eggs (make a batch in advance)
  • Canned or pre-made soups, with beans added
  • Pre-cut fruit and veg, or frozen versions
  • Asking a friend or family member to bring one meal

Tip: Treatment days are a good time to ask your care team's infusion nurse about light snacks — many centers keep crackers, juice, or popsicles on hand.

These are general ideas, not medical advice. Some chemo regimens call for extra food-safety precautions — like avoiding raw produce or unpasteurized foods when your immune system is low. Check with your oncology team about what applies to your treatment.

Why this feels so different

Chemo doesn't just treat cancer — it changes how food works

Treatment can dull your sense of taste, turn favorite meals into "no thanks," and make ordinary things — an empty stomach, a strong smell, a full plate — much harder to deal with. Add fatigue, and even reheating leftovers can feel like a project. None of that is unusual, and small changes can make a real difference.

Taste changes

Chemo can make food taste bland, bitter, or metallic — sometimes meal to meal. What sounds good can change quickly, and that's normal.

Appetite shifts

Nausea, fatigue, and stress can all reduce appetite. Eating smaller amounts more often is usually easier than three full meals.

Extra fatigue

Cooking, chewing, and even shopping take more energy during treatment — which is exactly when your body needs steady fuel the most.

From readers in treatment

What people going through chemo say

★★★★★
"I had terrible side effects from chemo until I started Dr. Quillin's nutritional program. My energy returned, nausea disappeared, and my overall health improved. My oncologist said I was one of her 'star patients.'"
Maria L. — Colon Cancer, Amazon review
★★★★★
"When I was diagnosed with cancer and going through chemotherapy over 20 years ago, I felt overwhelmed and terrified by the brutal side effects. I read Beating Cancer with Nutrition cover to cover while sitting in the chemo chair, and it gave me practical strategies that helped me manage the nausea, fatigue, and weakness far better than I expected. I truly believe it made a real difference in how I tolerated treatment — and more than twenty years later, I still keep this dog-eared, highlighted copy as a go-to resource."
Lisa R. — Cancer Survivor, Amazon review

Common questions

Will this help with nausea or appetite loss during chemo?

A large part of the book focuses on practical, food-based approaches to exactly these side effects. It's not a guarantee or a substitute for anti-nausea medication, but many readers use it alongside their treatment plan to make eating easier.

Does this replace what my oncology team tells me?

No. This book is designed to complement your treatment, not replace it — especially around food safety. Some chemo regimens require extra precautions, like avoiding raw produce when your immune system is low. Always check specifics with your care team.

I'm too tired to read right now — is there an audio version?

Yes — it's available on Audible. A lot of readers going through treatment say the audiobook is easier to get through on low-energy days.

Is this only for people currently in chemo?

It's written with active treatment in mind, but caregivers, survivors, and people newly diagnosed use it too — for meal planning, supporting a loved one, or preparing for what's ahead.

Is this based on real research?

Yes — the book references more than 1,000 studies, alongside Dr. Quillin's decades of clinical experience. See "Where this comes from" above for a few starting points if you'd like to read further yourself.
