The Scary Truth About Energy Drinks

The Scary Truth About Energy Drinks

The Energy Drink industry is massive and their marketing campaigns are just as big with Red Bull spending 40% of their entire revenue on marketing.  These companies convince you that these drinks are a convenient way of increasing energy and stamina, sharpening alertness, improving concentration and even maximising workouts and training to push you to extreme physical levels.  But what they don’t market is all the side effects of these beverages that could be causing you harm.  These companies main focus is on the vitamins and herbal extracts in these beverages that claim to make you feel invincible.  And as the FDA does not currently regulate these drinks, because they are categorised as dietary supplements the manufacturer does not need to prove their claims of efficacy or safety.  Recently in Australia, the Australian Beverages Council has rejected calls for a ‘tighter regulation’ on energy drinks arguing that Australia is already one of the most heavily regulated markets in the world.  This response by the Australian Beverages Council is part of an ongoing response by the industry concerns regarding energy drinks.  Currently the Australian regulations restrict the amount of caffeine in Australian energy drinks to 80mg for a standard 250mL can.  Even if we do have tighter regulations in Australia, the energy drinks available on our shelves still have potential side effects.  Here are a few of those potentially harmful side effects that you should consider…

The two main ingredients in energy drinks that could be doing you harm are caffeine and sugar.  Research suggests that 500 millilitres of caffeinated energy drinks a day lead to a faster heartbeat and a 10-point jump in systolic blood pressure which is a major risk if you are living with heart disease.  Too much caffeine in your diet can lead to rapid heart rate, interfere with sleep, increase urination as a diuretic, lead to nausea, headaches and anxiety.  It can also lead to muscle tremors from overstimulation of the nervous system and a decrease in bone mass density as it interferes with the body’s ability to absorb calcium.  If irregular, rapid heartbeat and increased blood pressure from excess caffeine isn’t enough to get you concerned then consider this:- 

In 2007, a 28-year-old Australian man suffered a cardiac arrest after consuming eight cans of an energy drink over 7 hours.  The drink contained 80 mg of caffeine each and the man had no previous history of chest complaints. 

One of the concerning things about the caffeine contained in these drinks is that their marketing strategy is youth orientated with a prominent presence at sporting events.  66% of energy drink consumers are aged between 13 and 35.  They are packaged in such a way that it is easy for adolescence to have instant access to large amounts of caffeine.  The inappropriate marketing to youth can increase the risk of overdose, abuse and dependence.  A major concern with our adolescence is the mixing of alcohol and energy drinks leading to an increased risk of alcohol injury and dependence.  According to the Journal of the American Medical Association, mixing alcohol and energy drinks may keep people awake for longer, allowing them to consume more alcohol then they ordinarily would.  A 2011 study of about 1,100 university students found those who consumed energy drinks where about 2.5 times more likely to meet the diagnostic criteria for alcohol dependence then those that did not consume energy drinks. 
 Energy drinks are calorie bombs, containing as much as 8-10 teaspoons of sugar.  This amount of sugar in combination with the caffeine will increase your blood sugar levels and give you an initial energy burst but this is usually followed by a sudden fall in blood sugar levels.  A drop in blood sugar levels can cause that ‘crash’ lethargic tired feeling again, causing ‘hypoglycaemia’ symptoms which are superficially relieved by consuming more sugar.  Hypoglycaemia occurs when the pancreas overreacts to the large amount of sugar in the blood and releases too much insulin.  Overwork on the pancreas can put stress on the pancreas as it eventually fails to produce adequate insulin when blood sugar levels rise.   Aside from the risk of insulin resistance and diabetes, excessive sugar intake can lead to obesity and open the gateway for many other chronic medical issues.  Sugar that is ingested and not absorbed can provide a good meal for harmful bacteria, candida and other fungi spores in the intestinal tract. Metabolic issues can arise when you overload your body with excessive amounts of additives and sugar.  Your body may go into overdrive to process this overload and produce stress hormones such as cortisol, to cope with the task. 
 Claims that these beverages can improve cognitive function may be so but in the short term.  Over time these drinks can decrease your ability to function due to the disruption on sleep cycles.  This can lead to sleep deprivation, nervousness, irritability and anxiety.  These symptoms can further increase you dependence on these beverages.   They become highly addictive and can produce mood swings and headaches when you finally realise what is going on and try to quit. 

Many argue that there are health benefits that come with energy drinks due to the natural herbal ingredients.  Ginseng acts on the adrenal glands, giving you energy and endurance, Gingko Biloba enhances memory and relieves stress and Guarana, also a caffeine containing stimulant believed to prevent atherosclerosis and remove lactic acid from your muscles.  While these herbal ingredients can be beneficial to your health after all the commercial processing you may not end up with a standard extract in your beverage that will have any of these health benefits at all.  To add to this argument the sugar and caffeine contained in these drinks can prevent the absorption of any of these nutrients.

Without the FDA regulating it is up to the consumer to be aware of the side effects, especially when these beverages are readily available to anyone – even an 11 year-old child.  One cannot ignore the growing concern about these highly caffeinated beverages.  Researchers warn that the long-term effects are unclear but that certain susceptible people risk dangerous, even life-threatening, effects on blood pressure, heart rate and brain function.  As the potential harmful effects of excessive consumption of energy drinks far outweighs their benefits it is best to avoid them all together and consider this list of natural energy boosters:

Exercise, socialise, eat small frequent meals, avoid high sugar foods, get a good nights sleep or take a power nap, address vitamin and mineral deficiencies, increase your exposure to sunlight, drink plenty of water, and breathe fresh air!

Dairy - Is It Really Necessary?

Dairy – is it really necessary?
If you look at the latest dietary guidelines from the USDA the recommended servings of milk is two to three cups a day. In fact these guidelines specifically advise individuals to get more fat-free or low-fat milk and dairy related products. But according to a great deal of recent research, milk and dairy isn’t necessarily an essential part of a healthy diet. Above all dairy may pose many health risks and some are starting to question if humans should be consuming milk at all. So how do we make sense of this information and ensure we get the essential nutrients that dairy has to offer?
First it is important to note that the USDAs recommendations are based on the nutrients that milk and dairy have to offer, these being calcium, potassium and vitamin D, which is added to fortified milks. So why do some experts believe cows milk is for calves only?

Here are some reasons that experts believe we should reconsider milk and milk products:
  • Many dairy products contain high saturated fat content and when consumed in large amounts can be a risk factor for heart disease by raising blood cholesterol levels, obesity and some types of cancer.
  • Milk allergies are common. Some individuals either react to one of the proteins in milk or to the milk sugar, lactose, causing lactose intolerance. Lactose intolerant individuals lack the enzyme lactase to effectively digest milk and dairy products. This can cause symptoms like cramping, bloating and diarrhoea ranging from mild to severe.
  • Those with mild lactose intolerance may be able to consume small amounts of milk without noticeable symptoms. However the nutritional benefits of milk may be lost when a lactase deficient individual cannot adequately digest milk.
  • Synthetic hormones in milk could be doing you harm. Recombinant bovine growth hormone (rBGH), also known as rBST, is a synthetic version of Bovine Growth Hormone (a naturally occurring growth hormone) that is injected into a cow to artificially maintain her milk production. The Food and Drug Administration and the World Health Organisation have independently stated that dairy products from rBST treated cows are safe for human consumption. However it is well known that rBST increases levels of the growth hormone insulin-like growth factor. Read below...
  • Hormones in milk have been linked to cancer. One reason the experts have made this link is due to insulin-like growth factor (IGF-1). Milk contains IGF-1 to assist calves to grow quickly. At elevated levels of IGF-1 have been found to stimulate the growth rate cancer cells in humans.
  • The process of pasteurisation destroys any harmful microorganisms and renders milk safe for everyone to drink. However it should be considered that conventional milk pasteurisation is a process that exposes milk to high temperatures and results in the denaturing of milk proteins, making them less useful in the body, the destruction of enzymes, including phosphatase, an enzyme that helps your body absorb calcium, destruction of vitamins B12, B6, and C. Pasteurisation also destroys all the beneficial bacteria in milk, including lactobacillus acidophilus.
With the dairy industry putting such an emphasis on bone health as part of their clever marketing ploy it makes good sense that people are encouraged to consume dairy products to ensure they are not deficient in any of these essential nutrients. However what is not well known is that bone strength is the result of several different factors – not just how much calcium you consume from dairy sources.
Important lifestyle factors that can limit the amount of bone loss in adulthood include:
● getting regular exercise – especially weight-bearing and muscle strengthening
● getting adequate vitamin D
● consuming enough vitamin K
● avoiding excessive consumption of preformed vitamin A
● limiting caffeine drinks.
For alternative sources of calcium check out this list recommended by Osteoporosis Australia – notice there is no dairy………………………
Almonds Broccoli Cucumber Silver beet Mustard Cabbage
Bok Choy Celery Chickpeas Dried Figs Dried Apricots
Calcium set tofu Unhulled tahini

As Easter is nearly upon us choose dairy free dark chocolate. This is just another reason to indulge in dark chocolate – it’s dairy free as well as being high in antioxidants. Choose brands like Haighs, Lindt 70% or Whittakers Dark Chocolate.
If you still have concerns about calcium intake and bone health after reading this article then it may be worthwhile considering talking to your Naturopathic Doctor as your digestive health and hormone balance also plays an important part in determining your bone health. They can also assist you with a large range of delicious alternatives to use.

"Milk is designed as the perfect food for newborn animals. They are dependent on milk to keep development and cell differentiation going. But milk contains a chemical-- insulin-like growth factor, or IGF-1 -- which girls have naturally as teenagers to help their breasts develop. This chemical-- which is designed to stimulate cell growth- can send the wrong signal to adult breast tissue."
Studies in the US and Canada in 1998 found that pre-menopausal women with the highest IGF-1 concentration in their blood had a far higher risk of developing breast cancer (similar studies have found a link between IGF-1 and prostate cancer).
"Over 70 per cent of the world's population is unable to digest the milk sugar, lactose. Lactose intolerance may be nature's early warning system: perhaps nature is trying to tell us that we're eating the wrong food."
