We all know we should be getting enough vitamins and minerals from the food we eat. If there's any doubt in our minds that we're missing certain nutrients, we take vitamins just to be sure. The problem is, consuming excessive amounts of certain vitamins and minerals can be harmful so check out this chart for a little recommended daily intake (RDI) refresher. Pay special attention to the amounts because some are needed in micrograms (mcg), and some are needed in grams (g).

Good to know these guidelines.
My sister's oncologist wants her to start taking loads of vitamins and supplements to help her through chemo and radiation therapies.
I started looking for the requirements for a 49 year old women and was just drawing a blank on what she needs, what's essential and what foods correspond to what vitamins. I needed to wide variety of foods because she's already a picky eater and I think she'll be even more so once the treatments start.
