What’s in the News - The Dark Side of ‘Energy Drinks’
Are you or your teenager using energy drinks? Think dance parties, staying up late to study for exams or pushing yourself to meet work deadlines. With our increasingly busy lifestyles many people are looking for a quick fix to get them through their day – or pumping throughout the night! Hello energy drinks. But recent research suggests these beverages could have a dark side and result in serious health consequences, particularly if you or your loved one consume large quantities.
What is an energy drink?
An energy drink is basically a sugary beverage with added caffeine and a few other ingredients, usually guarana (an additional, natural source of caffeine), taurine, ginseng, some vitamins and amino acids. Banned in certain countries, and once forbidden in Australia, multiple brands of energy drinks are now readily available at your local petrol station with the biggest sellers being Red Bull and V.
Celebrities often endorse energy drinks. Marketing is also highly geared towards young people, young adults and professionals promising improved concentration, performance and endurance. The result: the average age of consumption for energy drinks is about 17 years and energy drinks are seen as hip and cool. It is no wonder these drinks now account for 20 % of all beverages sold in convenience stores.
Why are there concerns?
According to recent research published in the Medical Journal of Australia, there has been a considerable rise in the number of toxic reactions and serious hospitalisations in young people due to the consumption of energy drinks.
Emergency calls to the NSW Poisons Information Centre (NSWPIC) have increased significantly over a seven year period, with reports of serious symptoms after drinking these beverages, such as heart palpitations, tremor, agitation, GI upset and chest pains. Other long-term effects of highly caffeinated drinks include hallucinations, seizures and a reduced blood supply to heart. There have even been reports of sudden death from heart attacks in young people directly linked to guzzling these caffeinated beverages.
But why the rise in health problems? People have been enjoying caffeinated drinks (both hot and cold) for decades. The concern among health authorities mainly revolves around the fact that it is super easy to unknowingly take in very high doses of caffeine from energy drinks. Consider this: one serve of energy drink can deliver to your body between 1.5 - 2 times the caffeine you would ingest from a cup of coffee, or three times the amount you’d get from a can of cola! See table 1 below. Although some flavoured iced coffees can supply as much or more caffeine per carton, young people are less likely to down multiple cartons of flavoured milks at a party as compared to taking ‘shots’ of energy drinks in succession.
Research has found that the average number of energy drinks consumed by people who make a distress call to NSWPIC is 5! This would be equivalent to you drinking about 7.5-10 cups of coffee in succession! But help calls have occurred even after one drink. It’s also quite common for these drinks to be taken with other caffeinated beverages, caffeine tablets, alcohol and even ecstasy - clearly a recipe for disaster!

Better ways to boost your energy levels
Due to the ease with which you could consume toxic doses of caffeine through energy drinks, and the increasing reports of harmful effects in young people, Australian researchers are calling for more specific health warnings to appear on pack.
In our opinion, as there is no universally safe level of intake for energy drinks, these are best avoided. Some people are so highly sensitive to caffeine they can develop a rapid heart rate and agitation to doses as small as 50 mg – the amount you would get from, say, a cup of black tea or one third or one quarter of a typical energy drink. One young client presenting to our Clinic for a separate reason reported she had previously taken energy drinks as they helped keep her full so she wouldn’t eat! But after an unexpected visit to the hospital emergency department triggered by these drinks, the girl was left with some permanent heart damage and now regrets ever taking a sip!
If you are flagging and need an energy boost it’s important to remember that your body is probably trying to tell you something - it needs rest or at least a mental break. Try to listen to your body’s cues more and organise more catch up sleep, regular rest time or earlier nights rather than trying to override these signals and pushing your body into overdrive with the aid of highly caffeinated drinks. Smarter beverages to temporarily boost energy levels in young people include flavoured mineral water and freshly squeezed juices. The quick acting carbohydrates will raise blood sugar levels very rapidly providing a lift. Often, however, a simple glass of water can also aid with concentration and performance.

The ideal yoghurt to use for this recipe is the ‘strained’ Greek variety, which gets naturally thickened as the liquid whey is drained. Unlike many yoghurt varieties, it contains no added gelatin or other animal based thickeners. Until recently however, you had to go to Greece to get it!
Enter Chobani Greek Yogurt. We tasted this ‘new kid on the block’ and have to say, we’re impressed! We’ll be using the plain fat free and 98 % fat free versions generally in cooking and for the above recipe idea.

What’s Fresh – Blueberries
Have you tried blueberries? Blueberries have long been regarded as one of natures ‘superfoods’ and with good reason. In addition to being low in energy - a handful will cost you only 158 kJ - blueberries are low in fat, low GI and provide a source of vitamin C. Blueberries are also packed full of antioxidants, being one of the highest sources of antioxidants of any fruit or vegetable.
Getting your daily dose (1/2 - 1 cup) of antioxidant-rich blueberries is important to help protect you from chronic diseases such as cancer and heart disease. Studies in rats have shown that a blueberry boosted diet can improve coordination and reverse the short-term memory loss associated with ageing. Blueberries are also an extremely rich source of anthocyanin, a phytonutrient important for your eye health. Similarly to cranberries, they have proven themselves useful in both preventing and treating urinary tract infections - something worth remembering.
Originally from North America, premium quality blueberries have been grown in Australia since the 1970s and you can buy fresh blueberries for 10 months of the year from July through to April. Farms now exist in Western Australia, South Australia, Tasmania, Southern NSW, Victoria, Southern QLD and Northern NSW.
There are three common varieties of blueberries known as the lowbush, highbush and rabbiteye. As their names suggest, the low and highbush shrubs grow at different heights whereas the rabbiteye got its name due to its ‘rabbit eye’ appearance during ripening. Although it won’t be stated on pack, you are most likely to see the highbush variety in your supermarket punnet as this variety accounts for more than 80 % of annual blueberry production.
Blueberries should always be refrigerated and stored in an airtight container away from moisture as leaving these delicate blue gems at room temperature will lead to early spoilage. Stored under the correct conditions your blueberries will keep fresh for up to two weeks.
3 ways with blueberries:
1. Start your day with a hearty breakfast of Swiss muesli topped with blueberries. Check out our easy recipe for Swiss Muesli with Mixed Berries Ideal if you have diabetes or a high cholesterol.
2. Take a whole punnet to school or work and eat at your desk when you get the munchies. A great healthy snack, which you can enjoy guilt-free straight from the packet!
3. Toss into a fruit smoothie for a really cool purple-blue colouring effect. Kids will love this!

Kitchen Tip - How to Store Leftover Ginger
Tired of finding your leftover fresh ginger dried out or mouldy the next time you go to use it?
As more and more recipes call for fresh ginger, this anti-inflammatory root vegetable is fast becoming a favourite in Australian households. However, few people realise you can successfully store leftover fresh ginger for future use and minimise your waste.
A great way to extend the life of your ginger rhizome is to freeze it. Examine the piece you have left and check there are no obvious blemishes on the skin. Then rinse (with the skin on), pat dry, wrap in paper towelling and pop into a paper bag before placing into the freezer.
Next time a recipe calls for ginger, simply grate the frozen ginger piece and add to your dish for a wonderfully fresh lift. Ginger stored under these conditions can last for up to two months.
