It sold sports nutrition 180 million in Norwegian sports shops this year, according to Dagens Næringsliv . But now a new Doctoral degree that sports drinks are not good for your teeth.
– Sports drinks seem to be more dangerous for teeth than we have thought. In addition to that there is a sour drink, so we drink it while we train. Then we often have less saliva in the mouth and saliva is very important for our teeth. Thus exacerbated the destructive effects of sports drinks, says Jenny Bogstad Søvik.
She is a research fellow at the Dental Faculty of the University of Oslo, and defended Wednesday with his doctorate.
Two-thirds had acid damage
The study charted she occurrence of acid damage to teeth to 795 youngsters aged 16-18. It turned out that two of the three had acid damage of mild or severe. This she examined against data youngsters gave about including lifestyle, diet and drinking methods. The conclusion was that two things gave more acid damage to teeth than other things: sports drinks and sour candy.
– The higher intake of sport drinks and acidic candies was, the greater the chance of acid damage to teeth, says Søvik.particular, acid damage large for those who ate candy three times a week, and / or drank more than 0.75 liters of sports drink daily. Those who also drank soda, diet soda and taste of water, were particularly vulnerable.
Things to eat and drink
The findings are supported by other research in the area. One study found that children who ate sour candy two to four times a week, had eight times the risk of acid damage compared to those who ate. Several other studies have shown that sports drinks provide higher risk of acid damage to teeth, including Milosevic and Moazzez ‘.
– I advise people to avoid sports drinks, and using water as a thirst quencher when coach says Søvik.– How does sports drinks from other sweetened beverages?
– Diet soda and taste of water, also provides acid damage. But we found a clear distinction with sports drinks, says Søvik.
Acid Injuries can make your teeth very sensitive. Then it can be painful to eat, drink and brush your teeth. Many will also have aesthetic ailments, as the teeth change color or get pits. If etching of tooth enamel is allowed to develop, one can at worst have greater problems, such as infections of the jaw.
– Do not sport drinks
On the fitness iTrain in Bergen, few sports drinks to see. Where they resort to water.
– Personal I drink it, but it might work for those who drink it. I grew up with that one should not drink like that. Mom said it was not good, and I’ve held on to since I was little, says Gustav Wictor (21).
– I do not drink like that drink. I think water is best. It increases my energy level, says Anna Melnuchuk (23).Truls Raastad professor of sports physiology at the Norwegian School of Sport Sciences. He believes few recreational athletes need sports drinks while exercising. But can you participate in competitions lasting for over an hour and a half, or ball games lasting over an hour, then a sport drink better performance, says Raastad referring to research in this area.
– The longer duration and higher intensity of competition, the more important it becomes a sports drink. Runs one marathon, a tratlon or bicycles Birken, for instance, so one needs to be supplied with fast carbs, says Raastad.
How can you make “sports drink”
Jonny Hisdal physiologist at Oslo University, agrees that sports drinks can be useful if you train intensively and long. But he believes a homemade recipe of juice and water can do as good advantage.
– If you exercise longer than an hour and a half of high intensity, beginning with carbohydrate depleted. Then it is wise to ingest carbohydrates. It is best to provide this through drink, because it goes faster in the blood. However, a mixture of one liter of juice and a liter of water, can make as good use as a sports drink. It is the same sugar content as you have in your blood.
– Drinking one soda or juice, which contains 10 to 12 percent sugar, it will take longer before it enters the bloodstream. Then pull fluid out of the blood into the intestine, says Hisdal.
The genes affecting
Jenny Bogstad Sovik also did a complex gene analysis in his doctorate. When she found that not only is the food and drink that can give you acid erosion of teeth.
– We saw that variasjener in our genes that build the enamel, can affect how susceptible they are to acid damage, says Søvik .
This is the first study indicating an association between genes and the widespread dental problem.
– What matters most to whether we get acid erosion of teeth, genes or what we eat and drink?
– Although you are more susceptible to acid damage due to your genes, so you still need to be exposed to acid. But it becomes the most during everyday life. But here further research is needed to say for certain, says Søvik.
