Ads for big brand named sports drinks are everywhere we look and our favourite athletes or our children’s idols all seem to be promoting and advocating these rehydrating drinks.
But are sport electrolyte drinks necessary? And how to choose the healthiest rehydration drink for you and your family?
Sports nutrition can be very confusing and misleading, but there are some great products out there, you just need to know what ingredients to avoid and when to consume such supplementary products.
When is it necessary to rehydrate yourself or your kids with an electrolyte-based drink?
For the average adult or child who engages in 30-45 minutes of low-moderate intensity exercise, sports drinks are generally unnecessary and water is more than sufficient to achieve optimal hydration. Examples of low–moderate exercise are 30-45 minutes of yoga, walking, gentle weights, medium paced bike riding or swimming, or light netball, cricket and footy drill based sessions.
In contrast, electrolyte replacement is required post high intensity exercise of 30-45 minutes plus. The best way to gauge if an electrolyte replacement is needed is:
- If a serious sweat has been broken
- You are exercising at a high intensity
- You have competed in a long distance race
- You have engaged in a competitive game like football or netball
- If the exercise has lasted for more then 60 minutes
When choosing an electrolyte drink what should you avoid?
Probably surprisingly for most people, Gatorade and Powerade are not ideal rehydration formulas for a number of reasons. Both contain high amounts of processed sugar, from 25g up to 40g per serving, which is more processed sugar then any athlete needs!
If you go for the low or no sugar option these are filled with artificial sweeteners, which are even worse for us then sugar. They both also contain artificial flavours and colours, which is why they are so bright and colourful – appealing to kids, but not so appealing to our insides.
Here are some examples of what is in these drinks and why to avoid these ingredients:
- Red#40: a suspected carcinogen, linked to allergic reactions in sensitive individuals
- Yellow#5: can promote asthma attacks, behaviour disturbances and is a suspected carcinogen
- Blue#133: may cause allergic reactions in sensitive individuals, hyperactivity and is a suspected carcinogen
- Sucralose: artificial sweetener found to cause adverse effects on gut tissue, may case DNA damage in the gut and is found to reduce beneficial gut bacteria levels
- PEG: can’t be absorbed in the digestive tract properly, and can induce diarrhoea which is not what an athlete wants, it can also commonly cause cramps, bloating and in sensitive people vomiting.
What are the healthier options on the market?
- Endura endura.com.au – free from artificial colours, flavours, sweeteners and PEG. Contains an even balance of easily absorbable key electrolytes. However most Endura products contain about 15-20g of sugar per serve, so this should not be drunk in excess and I would only recommended this rehydration formula for higher intensity exercise, where carbohydrate replacement is necessary.
- Bioceuticals Ultra Muscleze – Free from artificial colours, flavours, sweeteners, processed sugar and PEG. It is high in magnesium, contains key electrolytes as well as some B vitamins and amino acids, which assist with optimal muscle recovery and rehydration. Found only in health food stores or from a natural health practitioner.
- Organic pure coconut water: a great completely natural option. It has been found in studies to rehydrate athletes just as well as commercial sports drinks and was tolerated by athletes significantly better then commercial sports drinks post exercise with no gastric complaints recorded. It contains lower all natural sugar levels, but is slightly lower in optimal sodium and magnesium levels for higher intensity athletes.
There are a lot of healthier alternatives, but organic pure coconut water is my number one choice post exercise for moderate to short high intensity sessions. However for more endurance exercise, I would still recommend coconut water, but complement it with some Ultra Muscleze or Endura, to ensure optimal magnesium and sodium chloride levels are obtained.
