People who ate high-sodium, low-potassium diets had a higher risk of dying from a heart attack or any cause.Ī study in the Archives of Internal Medicine found that: diet is just the opposite: Americans average about 3,300 milligrams of sodium per day, about 75% of which comes from processed foods, while only getting about 2,900 milligrams of potassium each day. Our bodies need far more potassium than sodium each day, but the typical U.S. High salt intake increases blood pressure, which can lead to heart disease, while high potassium intake can help relax blood vessels and excrete sodium while decreasing blood pressure. Both are essential nutrients that play key roles in maintaining physiological balance, and both have been linked to the risk of chronic diseases, especially cardiovascular disease. Potassium and sodium are closely interconnected but have opposite effects in the body. The functions of sodium and potassium in the body are closely related and often studied together. It is estimated that the average daily intake of potassium in adults is about 2,320 mg for women and 3,016 mg for men. For men 14-18 years of age, the AI is 3,000 mg for men 19+, 3,400 mg.For pregnant and lactating women, the AI ranges from 2,500-2,900 depending on age. For women 14-18 years of age, the AI is 2,300 mg daily for women 19+, 2,600 mg.However, the National Academy of Medicine has established an Adequate Intake (AI) for potassium. Dietary Reference Intakes state that there is not enough evidence to establish a Recommended Dietary Allowance (RDA) for potassium. Potassium also helps muscles to contract and supports normal blood pressure. Sodium, its counterpart, maintains normal fluid levels outside of cells. Its main role in the body is to help maintain normal levels of fluid inside our cells. Potassium is found naturally in many foods and as a supplement. It is sometimes referred to as an electrolyte because it carries a small electrical charge that activates various cell and nerve functions. Potassium is an essential mineral that is needed by all tissues in the body.
