Just thought I'd add a little true experience here since it's dealing w/ red blood cells. I think I posted this before when it happened a couple of weeks ago but in case you didn't see it I will repost it.
My grandson is 3 eyars old & undergoing chemo for leukemia. After his first round of the garbage, his little body was so compromised that his red cell count was dangerously low & he could not go home b/c of it. The MDs allowed me to take him fresh oranges & he started eating 6-8 a day & within 48 hours his RBC came up so high, they immediately released him to go home. This was the week before Christmas & the MDs had already told my daughter, his mom, that there was no way he was going to get to leave the hospital, even for christmas.
I was already a fan of oranges but now I love them even more. I am staying the weekend w/ him @ the hospital & I just purchased a juicer & a large bag of organic oranges to take for him.
