"Whether people are athletes or not, the human body is constantly losing water through normal human functions"
For generations, Gatorade and similar electrolyte beverages have been helpful tools for athletes seeking a competitive edge. In 1965, Dr. Robert Cade and a team of scientists at the University of Florida College of Medicine created Gatorade to help their football players combat heat exhaustion and muscle cramps during long practices in extreme temperatures. The drink's winning formula of water, sodium, potassium and sugar works effectively with the human body to keep users hydrated, refueling them with energy and optimizing muscle function. While I don't work for or receive funding from Gatorade, as a registered dietitian and nutrition instructor, I've watched how specific electrolyte beverages can be handpicked to boost hydration in hospitalized patients, student athletes and even myself. And while Gatorade was one of the first electrolyte beverages heavily marketed to consumers, its ingredient combination has paved the way for the creation of even more sport and electrolyte beverages on the grocery store shelves today. If you're looking to gain a specific nutritional edge from a sports drink, you can seek out a registered dietitian for an individualized plan. Otherwise, if you've ever wondered what makes these colorful beverages a nutrition attraction, here's a closer look at some key ingredients. The importance of hydration Whether people are athletes or not, the human body is constantly losing water through normal human functions such as sweating, urinating and even breathing. When water is lost, the body also excretes key electrolytes such as potassium and sodium. These electrolytes are crucial for everything from heart function to muscle contractions. Electrolytes get their "electro" name from having an electrical charge when dissolved in water. This charge allows them to work throughout the body in chemical reactions that maintain normal brain functioning, balance fluids inside and outside of body cells and even balance how acidic or alkaline your…
