As I stutter through recovery from LungMutiny2010, I’m paying more attention to my diet. So as I try to go out for my 10-minute walk everyday, I still drink some sports drink — usually Gatorade made from the massive vat of powder you can buy at Costco.
We tend to get plenty of sodium in our diet — far too much in the U.S. actually — but I always worry about potassium when I’m sweating (Disclaimer: I am not an exercise physiologist or a cardiovascular or nephrology physician.)
I always thought that the widely-sold sports drinks were the best sources of potassium outside of eating bananas or some dried fruits. I was surprised to learn that an 8-ounce serving of orange juice contains 18-fold more potassium than an 8-ounce serving of Gatorade® (450 mg vs. 25 mg). Who knew?
I suspect this is a good thing when exercising, but perhaps a concern for hypertensive patients who must monitor their potassium levels.
Is there anyone with more practical knowledge about potassium and physiology willing to weigh in? Is a dilute, no-pulp orange juice (maybe 1:1 with water) a good adjunct to a sports drink when carrying multiple bottles of beverages on a bike ride or trail run?
