Potassium supplementation is mainly for prevention. Elderly people who have been taking diuretic antihypertensive drugs for a long time, or those with poor gastrointestinal absorption function, can not only go to the hospital for regular examinations, but also often eat potassium-supplementing foods. Tea is a food rich in potassium; followed by beans; vegetables rich in potassium include spinach, celery, amaranth, sweet potatoes, mushrooms, etc. In addition, cornmeal, sweet potatoes, milk, eggs, carp and other foods also contain a certain amount of potassium. Fruits rich in potassium include bananas, kiwis, grapes, grapefruits, strawberries, etc. Seaweed foods are also rich in potassium, and eating more is good for your heart.

It should be noted that potassium supplementation is best through dietary supplements. The use of potassium supplementation drugs requires the guidance of professional doctors in regular hospitals. Improper or even excessive potassium supplementation can cause serious harm to the body, leading to confusion, difficulty breathing, and even cardiac arrest.
