6. WHAT’S HOT! 5. Suggest a health risk associated with high intake of sodium? http://health.ninemsn.com.au/dietandnutrition/nutrition/693802/sports-drinks-the-real-facts The sodium in sports drinks plays a valuable role in improving fluid absorption and the desire to drink. Sodium can also play a role in replacing the large salt losses that can occur in long events (e.g. ironman triathlons) or for salty sweaters. Sports drinks have a similar sodium content to foods such as milk, bread and breakfast cereal, but are much better tolerated during exercise. You should always experiment with sports drinks in training before using them in competition. Not drinking enough sports drink, or drinking a lot in a short period of time, can cause gastrointestinal upset. Drink small amounts frequently to minimise problems.
