What is Cancer’s Fav Food? Red meat, chicken, fish, eggs, cheese, tofu… to some these may sound like “clean” or “high-protein” foods, but for many cancers, they’re actually a buffet of glutamine, the amino acid tumors are addicted to. In cancers like brain, breast, lung, pancreatic, cervical, and colorectal, glutamine becomes the real powerhouse, not glucose. It fuels cell division, DNA repair, antioxidant defense and generates up to 22 ATP per molecule, compared to just 2 ATP from glucose in cancer cells. Even though cancer cells take in lots of glucose, they use it inefficiently. Healthy cells get ~36 ATP from glucose. Cancer cells? Just ~2 ATP , most of the sugar is dumped as lactate. That’s the Warburg Effect, and it’s like filling a leaking bucket. According to a study from the Siteman Cancer Center (Patti et al., 2022), cancer cells try to use glucose normally, but their system gets overwhelmed. And in Wise & Thompson’s study (J Clin Invest, 2010): “To the cancer cell, gluta...
