I just did a quick check of our nutrient data tool, and I find it hard to believe that she could become hypokalemic (pathologically low in potassium) in such a short time.

(note - 100g = 3½ oz)

- 100g average beef cut provides 380 mg potassium

- 100g average pork cut provides 390mg potassium

- 100g tuna packed in water provides 240mg potassium

- 100g chicken .. 230mg potassium

- 100g plain sole fillet ... 360mg potassium

- 100g cheese provides 750mg calcium

Low calcium levels tend to be a chronic condition ... it doesn't just happen in 2 weeks. If there's insufficient calcium coming from the diet, then the body turns to bone and uses that. Unless there's a metabolic disorder, such as hypoparathyroidism or kidney disease.

I'd stamp this one with a big question mark.
