Doc said that likely helped starve the cancer.
"Dietary change" went from a 'cup-of-soup'/day down to nothing/day for the last week. (so, the specific amino acids didn't matter)
bone broth is a good nutritious thing when one can’t eat due to chemo or whatever- even good to have while fasting from solid foods-
I had colon cancer in 1996. My main side effect from chemo and radiation was severe diarrhea. The only food I could begin to hold in was rice soaked with chicken broth. I lost about 40 pounds over the 7 week period of diarrhea.
After the end of the diarrheal period, and after the internal radiation burns healed up, my doc said I needed to gain weight. That was not a problem at all, because I was always hungry and everything tasted wonderful. After 3 months I had gained all the weight back, and then some.
