A low sodium diet is a dietary intervention in which reduced sodium intake reduces the excretion of water but does not appear to influence overall body weight, or systolic blood pressure. The American Heart Association has recommended a sodium intake of fewer than 1500 milligrams per day for healthy adults. In other words, a low-sodium diet is one that limits sodium consumption to no more than 1500 mg every day. In addition to being good for your heart, a low-sodium diet can help boost your energy levels and help you lose weight. Conversely, consuming excess amounts of salt may lead to increased blood pressure and chronic diseases such as diabetes and Alzheimer's Disease.
