As is well known, for patients with hypertension, proper potassium supplementation has a regulatory effect on blood vessels and can prevent the occurrence of stroke.
Among many foods, besides soybeans, the highest in potassium are surprisingly three dried vegetables—dried shiitake mushrooms, dried tremella, and dried chili peppers. Professor Li Shuyuan, a standing director of the Chinese Nutrition Society, said that these three dried vegetables each contain over 1000 milligrams of potassium per 100 grams, far exceeding the potassium content of other foods. Regular consumption of these three foods means you don't have to worry about insufficient potassium intake in your body. The reason these three dried vegetables are the highest in potassium is that these vegetables are already high in potassium when fresh. After being made into dried vegetables, they become more concentrated than before, but the potassium content is not reduced or destroyed at all, thus becoming the three foods with the highest potassium content.
When we mix vegetables, we can occasionally add some dried chili peppers, which can not only supplement potassium but also add flavor. For dried shiitake mushrooms and dried tremella, they can be simply rehydrated and then steamed or used in soups, which is more conducive to potassium absorption. Such a diet can be chosen by patients with cardiovascular and cerebrovascular diseases. However, if there are also patients with kidney disease or renal failure, it is best not to eat this way, because in patients with chronic renal failure, the kidney's ability to regulate potassium metabolism is significantly reduced, making it difficult to maintain the balance of potassium metabolism, leading to hyperkalemia.
