Re: hoping to attract Cesium Chloride users

Yes, I would definitely do a combination.

Here's a list of the foods which are richest in potassium:

All meats, poultry and fish are high in potassium.

Apricots (fresh or dried, not canned)
Avocado
Banana
Cantaloupe
Honeydew
Kiwi
Lima beans
Milk
Oranges and orange juice
Potatoes (baked are highest, you must eat the peel)
Prunes
Spinach
Tomatoes
Vegetable juice
Winter squash

I hope this helps!
