If the news reports are to be believed, it's a frightening fad: teens gulping down protein shakes and ending up in hospital. According to the Sydney Morning Herald, some protein shakes bought online are dangerous and cause a wide range of health problems, as well as death. Here we delve deeper into the issue.
Protein Shake Investigation
In 2011, the NSW Food Authority embarked on an investigation into sports foods, including protein shakes. This followed concerns that there had been a rising number of hospital admissions for dizziness, vomiting, increased heart rate and death due to protein powders.
The investigation resulted in the Therapeutic Goods Administration (TGA) banning the ingredient 1,3-dimethylamylamine (DMAA) which can be found in some protein powders.
DMAA has been linked to high blood pressure, strokes, bleeding in the brain and several psychiatric disorders.
Beyond DMAA
With DMAA banned, we can assume that less dangerous protein drinks and powders will be sold to Australian consumers. However, experts are still concerned that products containing DMAA can be bought online from overseas suppliers.
But what about protein shakes that don't contain DMAA? Are they still healthy?
The British Dietetic Association says it depends on how much you have. They say consuming extra protein over time places pressure on the kidneys and liver.
Peter Day, director of enforcement and compliance at the Food Authority agrees. He says many people – particularly teens who want to bulk up – ignore the manufacturer's instructions and take more than double the recommended amount of protein powder.
"They don't read the instructions and end up with a high heart rate and risk of a stroke," he told SMH.
The Healthy Way to Get Protein
Before adding protein to your diet, it's wise to consult a naturopath, dietitian or nutritionist. They'll be able to assess your diet and evaluate your need for additional protein.
If you decide to use protein powders, always read the directions. If the tub says to use one scoop, stick to one scoop.
And if you're looking to lose weight, check the sugar content on the pack. Many protein powders are full of sugar, which won't help your waistline.
Above all, remember that the best way to get all the nutrients you need is through a balanced diet of fresh whole foods.
