Corn is not high in potassium compared to foods such as soybeans and seaweed, but it is high in potassium compared to foods such as cucumbers. The potassium content of corn is not very high compared to many foods, for example, according to nutritional research statistics, every 100g of fresh corn contains only 238mg of potassium, dry white corn contains about 262mg of potassium, while the same 100g of soybeans, nori, respectively, contains 1503mg and 1796mg of potassium. However, corn is not the lowest potassium food, for example, 100g of cucumber contains only 102mg of potassium. Potassium is widely present in the body’s intracellular fluid, not only to maintain normal intracellular osmotic pressure, as well as intra- and extracellular ions, acid-base balance, but also to the neuromuscular play a role in the normal physiological functions, to maintain normal carbohydrate and protein metabolism, so that the cardiac muscle to play a role in the normal function of the positive role. Those with severe potassium deficiency may have abnormal reactions such as cardiac arrhythmia and muscle weakness, and such patients should actively go to the hospital for treatment.
