Sodas and health


| 6 Comments

We have talked about sodas and the effects to our health in class. We have also talked about the risk factors in following the new "rules"about drinking soda, which should be compared with cigarettes in terms of how society is receiving it. In a new study, analysis involved 194,095 participants; over a median follow-up of more than 8 years, 4462 incident cases occurred. There was a 23% higher risk of developing kidney stones in the highest category of consumption of sugar-sweetened cola compared with the lowest category and a 33% higher risk of developing kidney stones for sugar-sweetened noncola; there was a marginally significant higher risk of developing kidney stones for artificially sweetened noncola.

Kidney stones are no joke.  Over 200 components have been found in the stones, and they are mostly deposited while urinating. This is incredibly painful for somebody that is trying to pass a kidney stone. It is commonly known that fr every 4 men that form a kidney stone, one woman has one. Does anybody think that the experiment above could have ben caused by chance? Andrew has made it clear that everything can be caused by chance. But Is there a higher probability in this case?

Interesting. I wonder whether sex has anything to do with the likelihood of developing a kidney stone. Is it that men typically drink more sugary drinks than women? According to a study in this article (http://www.gallup.com/poll/156116/nearly-half-americans-drink-soda-daily.aspx), men are only 9% more likely to drink soda than women. This does not come close to a man's increased chance of developing a kidney stone. Perhaps chance is to blame, but third variables could also have something to do with it! I would like to see more studies like this.

This study seems like it is completely observational. Therefore, the results can't be used to establish significant a cause-effect relationship between drinking soda and developing kidney stones. However, I was impressed that the sample size was so big (194,095 participants) and the timeframe was so long (>8 years). Your post made me wonder whether kidney stones have any negative long term effects on a person even after they've been passed. I found a pretty good site that addresses it:

It's apparently not just kidney stones that are a culprit: tea plays a factor as well. The mixture oxalate, one of the key chemicals that lead to the formation of kidney stones. "For people who have a tendency to form the most common type of kidney stones, iced tea is one of the worst things to drink," said Dr. John Milner, assistant professor, Department of Urology, Loyola University Chicago Stritch School of Medicine. OVerall, the best way to prevent is to drink plenty of water.

It seems like it could very well be a legit thing. It seems like the numbers are close but when you think of it as being out of 194000 people 6 percent represents close to 12 thousand people. I don't think that would just happen by coincidence. Maybe since there are a lot more chemicals in the non cola sugar sweetened soda that your kidneys to need filter out that they are more likely to build up kidney stones. Either way kidney stones are being created due to soda wether it non cola or not. But what should they do about it, people aren't gonna stop drinking soda because of kidney stones because they still happen so rarely. In the huffington post article they say if you exercise and drink a lot of water its a good way to help protect yourself from kidney stones, which makes sense because exercise and hydrating help against anything.

I think chance could definitely have played a part in this study, but then again like you mentioned chance is always a potential factor. In regards to the study though i feel like there are a lot of variables that could have affected the kidney stones in the 8 years the study was conducted. For example like Greg said, gender could play a role in the development in kidney stones. Personally, the first thing that came to my mind was maybe it isn't sod that's the problem but sugar in general. Is it excess sugar that is causing the increase in kidney stones? Well, I looked into it and according to the National Kidney Foundation, in order to decrease your chances of developing kidney stones it is smart to limit the amount of sugar and sugary foods you consume! Yu can check out the National kidney Foundation and get more information about kidney stones here -> http://www.kidney.org/atoz/content/kidneystones.cfm

It seems like there is always a heightened risk with artificially sweetened colas, yet no one can seem to prove that they are in fact bad for you, I wonder why? Possible government/industry collusion?

Anyway, I find it funny that while I was researching your the topic I came across this article: http://www.straightdope.com/columns/read/3062/will-coke-and-asparagus-cure-kidney-stones - that actually talks about coke and asparagus curing kidney stones.

I do find it worrying that articles like the ones you cited are not more publicly known, shouldn't we be made aware?
