    A study from the University of Miami has found daily consumption of diet soda can increase a person's risk of suffering a heart attack or stroke. The study was published in the Journal of General Internal Medicine.

    Reuters reported on the study and said researchers found drinking one can of diet soda per day raised a person's risk of suffering what are otherwise known as "vascular events" by as much as 44 percent.

    How does diet soda increase the risk of heart attack and stroke?

    Scientists aren't sure, although Reuters quoted the lead researcher, Hannah Gardner, as saying people who drink diet soda "may tend to have more unhealthy habits" overall. She noted participants who drank diet soda were also more likely to have weight issues and other health problems such as diabetes or high cholesterol.

    How was the study conducted?

    The report in the Journal of General Internal Medicine states the research involved some 2,564 participants in the Northern Manhattan Study. The participants were followed for 10 years. Their dietary habits and overall health were tracked to determine the correlation between diet soda consumption, and the 591 participants who experienced some sort of vascular event during that time span.

    What were the vital statistics of the participants?

    Of those who participated, 36 percent were male. The median age was 69 at the beginning of the study. 1,948 of those studied drank a diet soda less than once a month, while 453 were considered "light" diet soda consumers. Only 163 participants responded they drank diet soda daily.

    What are the implications?

    Private MD asserts the study could have long-range considerations for how the obesity epidemic in the U.S. is looked at. Many Americans are turning to diet soda in the belief that not only will doing so curb weight gain, but it is a healthier alternative to regular soda, which has been linked to diabetes and other major health issues. It might also be recommended in the future that doctors who treat people that consume diet soda pay extra attention to the health of those patients' hearts, including cholesterol tests and other health monitoring.

      The study does NOT say that 'daily consumption of diet soda can increase a person's risk of suffering a heart attack or stroke', as the author irresponsibly says. The author's logic is totally flawed. There is a link, just as there is a link between having pants with a 50" waist (diet soda) and being obese (heart attack). If those same people stop buying pants with a 50" waist (diet soda), they're no less likely to be obese (have a heart attack). Much more likely and logical is the probability that people who drink a diet soda every day are already overweight and therefore more susceptible to heart attack.

        Exactly. If I'm obese, I'm probably drinking diet soda in an effort to lose the weight. Similarly, if I'm diabetic (another heart attack causative factor), I'm probably drinking diet soda to avoid the sugar in regular soda.

        Scott, you're twisting yahoos lies with the truth. Shame on you. lol

      Am I reading correctly that old, overweight people who have bad eating habits and who happen to drink diet soda are at a higher risk of stroke or heart attack?

        I'll believe Aspartame and Acesulfame potassium are good for me when: 1) The methodology of scientific studies is refined to better examine the potential long-term risks of consuming these artificial sweeteners. 2) Said studies are conducted within the highest standards of scientific integrity and objectivity AND actually demonstrate a consistent body of evidence showing BENEFICIAL effects. 3) The FDA reinstates its database and reporting system for adverse reactions among consumers of these substances. 4) The FDA reforms itself to root out any conflicts of interest and regulatory capture 5) Whatever unstated, un-codified law that currently exists requiring all chewing and bubble gums on the market to contain one or both of these sweeteners is repealed 6) I can actually drink a can of Coke Zero without feeling like I'm dying.

      So, is it because people who drink diet soda, eat a lot of burgers and other bad food, or are there actually something in diet soda, that's bad for you? Be more specific please.

      This article is a sad specimen of amateur reporting and sensationalist, unfounded conjecture. I got rid of my television due to poor programming, I need to cut down on taking the Yahoo bait, too. Old-school, I can say this is very poor writing.

        Pajaru, You are right on about Yahoo. They have no journalistic integrity at all.
    • Grey  •  3 mths ago
      This is a Flawed science experiment.

      They did not conduct Health screenings of the participants, as they already may have been at risk for the same disease prior to consumption of the diet soda.

      They failed to show what the TRUE link between the two were.

      Is there a thumbs down button on this page anywhere? Also, when an article is titled "Diet soda linked to increased risk of heart attack and stroke", you want to actually have something in the article that proves this.... IE: "How does diet soda increase the risk of heart attack and stroke? Scientists aren't sure". Really?? So they have no proof but published this article? Man, must be a slow week in the news.....
      • John 3 mths ago
        Come on Zack, do you really expect to see many facts in a yahoo article ? They just want views with their junk articles. That's why they post headlines that have little or no facts or truth in them.

        It's a neurotoxin. Many countries in Europe and New Zealand have banned it altogether.
      • YT 2 mths ago
        LadyAgent, mmm, no it's not a neorutoxin. You're a neurotoxin. I read about you on an alternative-holistic-health marketing site. It's where I buy my broccoli pills. They tell the truth and you ARE a neurotoxin. Europe already banned you.

      If the diet soda contains nutrasweet then it contains methanol,aspartic acid and phenylanaline. Methanol can damage the conductive tissue in the heart and too much phenylanaline and aspartic acid can cause chemical imbalance,brain tumors,and possibly stroke.

      23% of the study had cardiac events. But the vast majority, 76% only drank diet drinks once a month or less. Only 2% drank diet drinks daily. Of the 23%, how many were rare, light, or heavy diet drink consumers?

      I think Juan has it right. Jack and diet coke with a triple cheesburger and onion rings just might put you under.

      the study is flawed in the sense that the age group being studied was from 60 to 80. Ofcourse they will have heart problems anyway, even if they drink no soda. The fact that young people were excluded from study resulted in a very misleading finding.
    • John  •  Fresno, California  •  3 mths ago
      This is absolutely typical of Yahoos misleading, alarmist headlines, which allot of times are just plain wrong. I usually drink diet Coke everyday, but I am also 5'11" tall and weigh 172 lbs. and exercise allot. This article is all about people who are obese and drink diet sodas to help curb there weight and not about diet soda itself causing these high numbers. Yahoo is the National Enquirer of the internet. They're pathetic. John

      1 word: Aspartame.... That's all you guys need to know. Just research what Aspartame is and what it does to the rats they test it on. Not to mention they discovered it while developing chemical weapons in WWII. It's amazing how many people don't know what it is. Aspartame=bacteria's waste#$%$

      Was this study done by the same morons who did the one joint a week study? Studies also show that going to college and getting a degree in something does not cure stupid. It just gives the graduate more tools to be "creatively stupid" with. Vanessa and Hannahs parents should demand their money back from the schools that educated their daughters.
    • Del  •  3 mths ago
      Splenda or Aspartame for the sweetener? Another shallow article.
    • kitsings1  •  3 mths ago
      There's no proven cause and effect here. As the researcher herself said that the correlation could be due to circumstances other than cause and effect. But now the whole country thinks for sure that diet soda CAUSES more incident of strokes. BAD REPORTING. The study did NOT prove cause and effect, and cause and effect should NOT be reported!
    • July  •  Yukon, Oklahoma  •  3 mths ago
      The chemicals in diet sodas are bad for you. When I stopped drinking diet sodas I stopped having body aches, brain fog, and irritability. Now if I drink a diet soda I feel as if someone's been beating me all over with a little hammer, which is my body's way of saying, "What's this crap? Why are you ingesting it?"
    • Justin  •  Dallas, Texas  •  3 mths ago
      Funny how my comment is the ONLY one that mentions Aspartame.... Wake up people. Simple research is easy!
