potassium

In most people's minds, high blood pressure is undoubtedly linked to salt intake. But there's another mineral that should also be considered — potassium. A recent review of several types of studies strongly indicates that it's not just a proper sodium level that helps one achieve, and maintain, normal blood pressure.
US health officials have long warned that too much salt intake as a child can raise lifelong risk of high blood pressure. However, a new study published in JAMA Pediatrics suggests it s actually potassium intake that kids should be aware of.
