Nutrition Strategy During Intensive Chemotherapy: How to Prepare for ASCT
A Practical Way of Thinking, Not a Diet Plan
During four months of high-intensity chemotherapy in preparation for autologous stem cell transplantation (ASCT), we chose healthier versions of foods we already enjoyed — using diet as damage control while still preserving pleasure whenever possible.
This is not a claim that food cures cancer. It doesn’t. But, when chemotherapy aggressively destroys malignant cells, it also places enormous strain on a living organism. Our goal with this nutritional shift was simple: don’t make the body’s job harder than it already is.
If you’re reading this as a patient, partner, or caregiver, take this as a framework, not a prescription.
The Six Systems We Tried to Protect
Rather than obsessing over calories or trends, we filtered every food decision through six questions.
A Crucial Boundary: Supplements
During Active Chemotherapy
Vitamin and mineral supplements were forbidden by the oncologist. The logic was uncomfortable, but clear: antioxidants protect healthy cells—and cancer cells too. In this phase, the priority was eliminating malignancy, even at the cost of some collateral damage.
Food stayed. Pills stopped.
After Chemotherapy Ended
At the end of the fourth chemotherapy cycle—during the pause between chemo and ASCT—his doctors actively prescribed supplements to address chemotherapy-related nutritional depletion, but in a very targeted and time-specific way. He received:
- High-dose vitamin D: 50,000 IU in oil drops, taken once a week for six weeks, for a total of 300,000 IU
- Vitamin B complex injections: a cocktail of B1, B6, and B12, administered once per week for three weeks
The message from the medical team was clear: supplements are not the enemy—bad timing is.
Once the active phase ended, the focus shifted to rebuilding nerves, bones, and overall reserves before ASCT.
Food carried him through treatment. Supplements helped restore what treatment inevitably depleted.
Hydration As a Daily Ritual
Chemotherapy disrupted his circulation and temperature regulation, and the cold winter days in Chile certainly did not help. He also was not drinking enough plain water. We solved both problems at once by making hydration warm.
Two liters of light ginger tea—made from fresh ginger root, not a tea bag—diluted and not strong, became an all-day drink. Ginger for digestion and warmth, with one bag of chamomile for calm and one bag of rosehip for flavor. Not medicine—just something the body accepted easily.
He drank mostly tea, less plain water. That was fine. Hydration was pleasant and it worked.
Meals as Containers, Not Rules
Instead of designing perfect meals, we stabilized meal roles.
Breakfast
Light option (most days): Fermented dairy, oats, nuts, berries, banana for prebiotics. Easy to digest, prepared in advance, no morning decisions.
Strong option (twice per week): Eggs, mushrooms, cheese, leftovers from dinner
Lunch
Always protein plus vegetables. Meat was non-negotiable—this is a man with a lifelong and unapologetic commitment to red meat. However, beef taught us a hard lesson during chemo: it digested poorly and caused stomach pain. Poultry, pork, smaller portions of beef, fish, lentils, and gentler cooking proved much wiser companions.
Dinner
This is where real life entered. Cholesterol-friendly? Not always. Low carbs? Yes. Low-glycemic home-made versions of comfort food kept morale intact without pushing blood sugar or digestion too far. Pizza was his favorite in our gluten-free, low-glycemic index version.
Snacks were always healthy—roasted pumpkin seeds; juice from cooked beetroot with lemon and a little yogurt; or fruit such as a pear or an apple, depending on the mood.
One simple principle guided our daily food choices:
Food that causes stress—nutritional or emotional—is not therapeutic.
Dairy and Fermentation
This period also marked a first for us: we began making cheese at home, quickly grew fond of it, and have continued ever since. As part of the cheesemaking procedure, calcium chloride was added to the milk—an additional source of calcium that aligned well with supporting bone recovery. Our weekly production averages about 700 grams of cheese.
We were already preparing yogurt and kefir at home, a habit shaped partly by the high cost of yogurt in Chile and our level of consumption. Each week we produce roughly 6 liters of yogurt and 3 liters of kefir, ensuring continuity and control over quality.
Altogether, homemade dairy—yogurt, kefir, and cheese—provided calcium and probiotic support, alongside the practical reassurance that nutrition was actively aiding recovery. Fermented foods worked in the background, contributing to gastrointestinal comfort and supporting the gradual re-establishment of internal balance.
Chemotherapy Day
Chemo days were anything but normal. Energy crashed and digestion shifted. Surprisingly to everyone, he did not experience nausea; instead, his appetite spiked, and I was practically preparing two lunches on treatment days.
Always a little more substantial. It worked well for him on treatment days. Once, after eating lightly and heading to chemotherapy, he nearly fainted during needle insertion.
Food immediately upon his return from the hospital. It had to be served at once—he was intensely hungry.
After eating, his energy gradually faded and he became tired, needing to sleep. A 1–2 hour rest restored him, and he was ready for what he called his “normal lunch.”
The “normal lunch” included a satisfying portion of meat and vegetables. Afterwards, we prepared afternoon coffee, enjoyed ten minutes of conversation, and returned to working online for the rest of the day.
A Note on Caregivers (and Sanity)
On chemotherapy mornings, while others drove him to the clinic, I had a quiet couple of hours to myself — completely cancer-free time. Without it, I might have gone off the rails.
I walked in the park. Or wrote by hand in a paper notebook — one that absolutely had to have a beautiful cover to cheer me up. Thoughts, plans, fears, and occasionally strange ideas about the universe: waves, matter, intelligent clouds as the next advanced civilization. Some of it turned into clarity. Most of it turned into laughter. And every now and then, an idea surfaced that I might start a blog one day.
Then the door opens. "Honey, I'm starving!"
Back on track. Lunch number one. Sitting on the bed next to him while he falls asleep, just to make sure he's okay. Lunch number two. Right.
Cosmic theories quietly hid away in the closed notebook. Lunch number one warmed on the hot plate. Life continued.
A blog?
Be serious. You'll never write a blog.
Next post: a one-week menu. Apparently.
