They found the effect of the drinks on the teeth was the same and sometimes greater than the effect of orange juice, a drink which is already known to soften tooth enamel. Now some of their offspring are taking part in the Framingham Osteoporosis Study which involves extensive testing every four years by researchers from Tufts University in Boston. Read about our approach to external linking. But in 2001, the Birmingham team examined seven different brands of mineral water, again pouring them over extracted teeth to see what happened. The combination of a high sugar content coupled with acidity caused by the carbonisation that makes it fizzy, isn’t good. Carbonated water is a refreshing beverage and good alternative to sugary soft drinks. The eroding effects of sweet fizzy drinks add up over time (Credit: Getty Images). So if you want a change from plain old water, then although it’s mildly acidic, so far there isn’t strong evidence to suggest that it’s harmful to your bones, your stomach or your teeth. They looked in detail at the different types of drink consumed by more 2,500 taking part in the study. The reason is that phosphoric acid in the drink removes the oxide coating that has built up on the coin. Maybe not. Again, the evidence so far suggests not. But if you want to play safe and keep it away from your teeth, when you answer the question “still or sparkling”, perhaps you should also ask for a straw. If you drink a lot of sparkling water you might find you feel bloated, but researchers in Japan have found that this side-effect could be put to good use. It’s possible that it might somehow block calcium absorption – but no one yet knows how. But when it came to the erosive potential of that weak acid on the teeth, the effect was 100-times less than that of some other kinds of fizzy drinks. Some people have warned that any sparkling drink - even water - can be bad for us (Credit: Getty Images). They found that 900ml of gas was released from just 250ml of water, so not surprisingly the women’s stomachs distended slightly and the had the perception of feeling full, even though they hadn’t eaten. He argues that it’s not just the initial pH of a drink that matters, but how strongly the drink retains that acidity in the presence of other substances, because in a real-life mouth saliva is present, as well as other foods which might affect the levels of acidity. This is known as the buffering capacity. Both conditions improved in the people drinking sparkling water and showed no improvement in those drinking tap water. Sparkling water typically doesn’t contain any sweetener, so if sparkling water satisfies your cravings for something fizzy and lets you skip soda, you’re much better off. The authors hypothesise that the effect is probably down to caffeine and to the actions of phosphoric acid (not found in sparkling water) that are not yet well understood. Lemon and lime, and grapefruit were the most acidic flavours, probably because they use citric acid to give the nice taste. A case study published in 2009 of a 25-year-old bank worker whose front teeth wore out after four years of drinking half a litre of cola a day, followed by three years where he upped that to a litre-and-a-half each day and added in some fruit juice, is enough to frighten anyone. UK researchers tested how hydrating 13 different drinks were (based on urine output) and found that sparkling water was just as hydrating as plain water. If you’re not brave enough to say “tap” then sparkling can seem like a nice change. This website is produced by BBC Global News, a commercial company owned by the BBC (and just the BBC). The Framingham Heart study began in 1948 and followed a group of people over many years to discover more about the risk factors for heart disease. But it also depends on how you drink it. But a review of this practice in children with acute gastroenteritis found there’s little evidence that it works and that compared with rehydration powders – specifically constituted to contain replacement salts and sugars in the right proportions – such drinks contain far lower levels of sodium and potassium than you’d find in rehydration drinks. Barry Owens from the University of Tennessee College of Dentistry, Memphis, USA conducted a study back in 2007 comparing different fizzy drinks. Other carbonated drinks made no difference. But what about sparkling mineral water? They found that the longer a drink stayed in the mouth, the more noticeable the drop in pH in that person’s mouth. So flavoured mineral waters shouldn’t be considered as harmless as water, but how about sparkling water with no added flavours? “Still or sparkling?” they say to you in restaurants. So as far as bones and stomachs go, so far drinking sparkling water seems to be fine. A small, Canadian study published in 2001 found that teenagers who drank lots of fizzy drinks (not sparkling water) had less calcium in their bones, but they couldn’t tell whether this was a problem with the drinks themselves or that it was because people who drank them might favour them instead of milk.
