One good thing I learned in this book is that Potassium is so very important.
There are three pages on Potassium but of the many things he talks about one caught my eye is that when potassium in low, there is a greater risk of life-threatening arrhythmias, heart failure and stroke. hmmm don't want any of that....

Pot's main duty of to maintaining the proper function of our cell walls. It's second duty is to support the concentration of Magnesium, a major heart nutrient.

It talks about water pills depleting the potassium and many people take those, not me but many.
He recommended eating foods with higher potassium which are almonds, halibut, cod, turkey, chicken breast, and sirloin. Some veggies are mushrooms, chard, and spinach. Fruits he recommended are Cantaloupe and Avocados.
