The upside to modern cancer treatment, like chemotherapy, is obvious; people are living more, and living longer. The downside is that some food tastes terrible.
Chemotherapy, by design, kills all fast-growing cells in the body. As cancer cells die, so do all the healthy fast-growing cells, including the cells responsible for hair growth and taste buds. So your hair falls out and everything tastes metallic.
"Here they are, critically ill, needing good nutrition more than ever, and they can't enjoy food? It's beyond unfair," said Dan Han, a psychologist at the University of Kentucky.
