answer:Well Chemotherapy is a radical therapy aimed to destroy cells in a certain area, it also damages good cells but this is all in good practice. First off we must understand what an anti-oxidant does. In a nut shell it’s a cell repairer. An oxidant is something that oxides, so anti-oxidant is good. Flavonoids, like Vitamin C (ascorbic acid) is an anti-oxidant that helps repairs cells. So instead of losing those cells and your body having to remake them and using energy there, an anti-oxidant can revitalize cells, so that it functions normally again. I’m a binge reader so I don’t retain accurate accurate facts for long or know exactly how to explain it, I’m no expert. I know staying away from inflammatory/processed foods can help reduce the risk of cancer and of course loading up on vitamins is good. You know a good source to reference these sort of questions I use “LIVESTRONG.COM” simply type in your question and 80% of the time it’s there! (That’s been my experience at least.) Nutrition is a fairly new science if you think about the whole existence of man kind. There have been tons of observations with lab rats who in take tons of antioxidants vs those who don’t.
