As I'm sure you're aware, we could find potassium in so many common foods such as spinach, carrot, orange and yogurt. Moreover, I've recently read that dry figs and other dried fruits have a high concentration of potassium. But how could we keep our potassium optimal levels every day? I don't know, but I'm sure that lots of fast foods are low in potassium. Of consequence, it's best to concentrate on eating a wide variety of whole foods every day.
After I had wrote this post I tried to find potassium in the meal :) So, we cooked potatoes with garlic, low-fat cheese and olive oil. And we didn't lose much time to cook it.
