Nutrition: What are electrolytes for and where can you find them?
A word of advice: don't neglect what's on your plate to avoid any deficiency. Potassium? You'll find it in peas and certain fruits like bananas, papayas, and dates. But also in vegetables like spinach, cabbage, and parsley.
Dairy products…
For magnesium, focus on dark green leafy vegetables like spinach. But also pulses. Dried fruits—apricots, figs, dates, etc.—and offal—like liver—also contain significant amounts. As do oilseeds (almonds, etc.). As for calcium, it's well known: dairy products (milk, yogurts, cottage cheese) are the top sources. These are also excellent sources of phosphate, as are eggs, fish, cocoa, sesame, and wheat germ.
Diagnostic tool?
It's also worth noting that these electrolytes could be a useful diagnostic tool for detecting certain eating disorders early on. According to research coordinated by the University of Ottawa, electrolyte abnormalities appear well before the disorder in question is diagnosed. About a year!
