Everyone is different and many cannot get the exercise they need, I'm one of them. I exercised a LOT into my 60's and then with OA getting worse, I had to back down. With this narley hip replacement, I have a hard time walking.

I cannot get 4700mg of potassium from foods, I'd be sitting around eating lbs all day. Many don't even know about the need for potassium.

I had a friend who is now gone, but she was paranoid about salt intake, didn't know much about potassium but ate a banana daily 400mg and the other foods she ate.... but was no where getting enough potassium in her body.

She would pass out a lot and end up in the ER and was found to be so potassium deficient and had to have potassium IV's to be released... She was aging and again the old folks mostly are happy to be walking. Not many 80 yr old marathoners.

Kiwi, it's good that you can meet your country's RDA with foods...is the RDA the same as in the U.S., just curious.
