What Should You Eat—and Avoid—During Leukemia Treatment?
When you're facing acute myeloid leukemia (AML), you may wonder whether certain foods could support your treatment or if some might interfere with your body’s response. While food is not a replacement for medical care, emerging research shows that specific compounds in everyday ingredients can influence the very pathways that drive leukemia.
Here’s what the science says—and what it means for your plate.
Key Findings:
- Lycopene in tomatoes helps protect mitochondria and reduces harmful inflammation [1, 2].
- Luteolin in lemon peel supports immune signaling and hormone regulation [5, 6].
- Butyric acid in bergamot has conflicting effects on growth pathways—making it one to approach carefully [7, 8].
- Cholesterol in anchovies and dihydrocapsaicin in cayenne pepper may inadvertently support cancer survival mechanisms [9–12].
Why Nutrition Matters in AML
AML is driven by specific genetic errors. Mutations in genes like FLT3 tell blood cells to grow nonstop. Others, like NPM1 and DNMT3A, disrupt normal cell function and repair. These changes hijack pathways that control growth, inflammation, and DNA repair.
What you eat can gently influence these same pathways. Some food compounds may help calm overactive signals. Others might accidentally fuel them. Understanding this can help you make informed choices during your treatment.

Foods That May Support Your Body’s Defense
Tomatoes: A Source of Protective Compounds
Tomatoes contain lycopene, a bright red antioxidant. In laboratory studies, lycopene has been shown to activate mitochondrial biogenesis [1]—helping cells produce energy more efficiently. It also inhibits inflammasomes [2], protein complexes that trigger harmful inflammation.
Tomatoes are also a source of folic acid. This B vitamin activates the NOTCH1 signaling pathway [3], which helps regulate cell development. In AML, controlled NOTCH signaling may help restore order to disordered growth. Folic acid also activates the mTOR signaling pathway [4], a system that helps balance cell growth and survival.
Try adding fresh tomatoes to salads, sauces, or soups. Cooking tomatoes can increase the availability of lycopene.
Lemon Peel: More Than Just Zest
Don’t discard that lemon peel—it’s rich in luteolin, a flavonoid with intriguing properties. Luteolin activates toll-like receptor signaling [5], a key part of your immune system’s first response to threats. It also supports steroid hormone biosynthesis [6], which helps maintain hormonal balance during stress.
Add finely grated organic lemon zest to dressings, teas, or baked goods.

Foods to Approach with Caution
Bergamot: A Complicated Citrus
Bergamot, often used in Earl Grey tea, contains butyric acid. The research here is mixed: some studies show it activates the PI3K-Akt signaling pathway [7], which can encourage cell growth. Others suggest it inhibits that same pathway [8]. Until we know more, it may be wise to enjoy bergamot in moderation rather than in concentrated forms.
Anchovies: Watch the Cholesterol
Anchovies are a source of dietary cholesterol. In cancer models, cholesterol has been found to activate the Wnt signaling pathway [9] and PI3K/AKT signaling [10]—both involved in cell growth and survival. If you have AML, limiting high-cholesterol animal products may be a prudent choice.
Cayenne Pepper: Spice with Care
Cayenne pepper contains dihydrocapsaicin, which gives it its heat. Laboratory studies indicate that this compound inhibits apoptosis [11, 12]—the process of programmed cell death that helps the body remove damaged or dangerous cells. In the context of cancer, inhibiting apoptosis could potentially help unhealthy cells survive.
If you enjoy spice, consider using milder options like black pepper or sweet paprika.

A Final Word
Your diet during AML treatment should support your strength and well-being. While these findings come from laboratory research—not human clinical trials—they highlight how food can interact with biology on a molecular level.
Always talk with your oncology team before making significant dietary changes. They can help you personalize nutrition in a way that supports your treatment and overall health.
