“Boiling potatoes can reduce their nutritive value by causing the loss of minerals, including potassium, in which potatoes are rich, [causing them to] leach into the cooking water,” Akhavan noted.
Toby Amidor, MS, RD, CDN, FAND, an award-winning nutrition expert (who, full disclosure, is a partner with Idaho Potato), adds that in addition to fiber, potassium and iron, potatoes contain ...
The average potato has 0.075 mg solanine/g potato, which is equal to about 0.18 mg/kg based on average daily potato consumption. [ 19 ] Calculations have shown that 2 to 5 mg/kg of body weight is the likely toxic dose of glycoalkaloids like solanine in humans, with 3 to 6 mg/kg constituting the fatal dose. [ 20 ]
Deep frying potatoes at 170°C (338°F) is known to effectively lower glycoalkaloid levels (because they move into the frying fat), as does boiling (because solanine is water soluble), while microwaving is only somewhat effective, and freeze drying or dehydration has little effect.[10] [11] This does not make sense to me.
Potassium is the eighth or ninth most common element by mass (0.2%) in the human body, so that a 60 kg adult contains a total of about 120 g of potassium. [84] The body has about as much potassium as sulfur and chlorine, and only calcium and phosphorus are more abundant (with the exception of the ubiquitous CHON elements). [85]
She also notes that yams have more potassium, making sweet potatoes a better option for people with kidney disease who need to limit this nutrient. Related: 50 Easy Sweet Potato Recipes for the ...
Low potassium is caused by increased excretion of potassium, decreased consumption of potassium rich foods, movement of potassium into the cells, or certain endocrine diseases. [3] Excretion is the most common cause of hypokalemia and can be caused by diuretic use, metabolic acidosis , diabetic ketoacidosis , hyperaldosteronism , and renal ...
