ENERGY DRINK

Energy drinks can be useful when you’re training hard and need an extra boost for a tough session.

They can also be used as a quick pick-me-up during a slow afternoon at the office, but it’s important you don’t get to the stage where you become reliant on them.

When used in the right context, consuming energy drinks in moderation as part of a balanced diet can have advantages.

When you sweat, your body doesn’t just lose water — it gets rid of electrolytes as well. Not replacing these electrolytes can lead to a drop in performance and dehydration.

The Dietitians of Canada website advises looking for an energy drink that contains between 460 and 690 milligrams of sodium per liter. Those performing long-duration sports events may need slightly higher concentrations though.
