I’ve mentioned before that I have an enormous extended family and today I’m delighted to be able to share some insights from one of my family members. My cousin, Dr Lawrence Spriet, Professor and Chair of the Department of Human Health and Nutritional Sciences at the University of Guelph, was recently interviewed by The Ontarion about the proper use of sports drinks. I thought I’d share some of the key points from the article…

Dr. Lawrence Spriet
Sports drinks can be found everywhere these days, from your local gym to your local 7-eleven or corner shop. So are they just another every-man’s drink that we can drink whenever we like?
Dr Spriet points out that sports drinks were originally designed for elite athletes, so unless you’re training twice a day for hours at a time, they’re completely unnecessary for you. Water is perfectly adequate.
So what makes a sports drink so special? Sports drinks are made up of water, sugars (carbohydrates) and a small amount of electrolytes. These elements are vital for elite athletes who need to replace the copious amount of fluids they’ve lost through sweating.
As Dr Spriet explains, the water in your body contains 0.9% salt and your kidneys ensure this level remains constant. However, when you sweat the body can’t reproduce the liquid and salt without consumption of an outside source. If you’re an elite athlete it is critical these levels are corrected immediately and so the sports drink becomes essential.

Before you consume a sports drink consider whether your level of physical activity warrants it
Not to mention that the sugar contained in sports drinks helps fuel the brain. As many sports require quick decision making, keeping the brain fueled is just as important as keeping the body hydrated.
So, there is definitely a time and place for the not so humble sports drink. However, for the ordinary person who only exercises moderately… beware of the high sugar content contained in these drinks. They may taste good, but unless you’re going to burn all that sugar off, it’s just going to convert to fat!
