Do Diet Sodas Increase Your Risk Of Stroke?

Author: Dr. Stephen Chaney

diet soda badIs diet soda bad for you?  With over two third of Americans overweight or obese, it is clear that we are in a midst of an obesity epidemic. Multiple studies have shown that over consumption of sugar-sweetened beverages (soft drinks, energy drinks, and “fruit” juices that aren’t made from real fruit) are major drivers of the obesity epidemic. Because of these trends, many experts recommend substituting artificially sweetened beverages for sugar-sweetened beverages in the American diet.

Is that advice sound? Do diet sodas help prevent weight gain? Are they safe? The answers to those questions are not as clear as you might expect.

Do Diet Sodas Prevent Weight Gain?

diet soda make you fatThe answer to that question would seem to be a no-brainer. Substituting beverages with no calories for beverages with calories should lead to less weight gain. However, as I summarized in a previous “Health Tips From the Professor” article Do Diet Sodas Make You Fat, the answer is not clear at all. Some studies suggest that diet sodas help people lose weight. Other studies suggest diet sodas cause just as much weight gain as sugar-sweetened sodas.

With so much confusion in the literature, what should we believe? More importantly, what do the experts say? This January an international consortium of experts reviewed all of the pertinent literature and published a position paper on whether artificially sweetened beverages were of value in responding to the global obesity crisis (Borges et al, PLOS Medicine, DOI: 10.1371/journal.pmed.1002195).

These authors concluded:

  • “In summary, the available evidence…does not consistently demonstrate that artificially-sweetened beverages are effective for weight loss or preventing metabolic abnormalities [pre-diabetes and diabetes]. Evidence on the impact of artificially-sweetened beverages on child health is even more limited and inconclusive than in adults.”
  • “The absence of evidence to support the role of artificially sweetened beverages in preventing weight gain and the lack of studies on their long-term effects on health strengthen the position that artificially-sweetened beverages should not be promoted as part of a healthy diet.”

Is Diet Soda Bad For You?

In previous issues of “Health Tips From the Professor,” I have discussed other studies showing that diet sodas are just as likely as regular sodas to increase risk of diabetes Artificial Sweeteners and Diabetes and heart disease Soft Drinks and Heart Disease.

Even worse, a study published earlier this month (Pase et al, Stroke, DOI: 10.1161/STROKE.AHA.116.016027 ) concluded that diet sodas may significantly increase the risk of stroke and Alzheimer’s disease.

This study looked at 2888 participants of the Framingham Heart Study. The participants evaluated for risk of stroke had a mean age of 62 on enrollment. Those evaluated for risk of dementia had a mean age of 69 on enrollment. All subjects were followed for 10 years. Three food frequency questionnaires were administered during that 10-year period to evaluate consumption of diet and sugar-sweetened sodas. The results of the study were:

  • People consuming at least one diet soda per day over a 10-year period were 3X more likely to have a stroke or develop dementia (primarily Alzheimer’s disease) than people consuming no diet sodas.
  • No increased risk of stroke or dementia was seen for people consuming sugar-sweetened beverages. However, that does not mean that sugar-sweetened beverages are good for you. Previous studies have shown they increase the risk of obesity and diabetes.
  • When the data were corrected for hypertension, cardiovascular disease, and obesity (waist to hip ratio), diet sodas still increased the risk of having a stroke by 2.6-fold.
  • This is not the only study to show a link between diet sodas and stroke. Two other studies have come to the same conclusion, and in both of those studies the increased risk was also seen only with diet soda consumption, not with sugar-sweetened soda consumption.

The author of the study concluded by saying: “As the consumption of artificially sweetened soft drinks is increasing in our community, along with the prevalence of stroke and dementia, future research is needed to replicate our findings and to investigate the mechanisms underlying the reported association.”

I agree. Current evidence does not definitively prove that diet sodas cause stroke and Alzheimer’s, but these are life-changing adverse health outcomes. Further research to test this association is desperately needed to know whether or not diet soda is bad for you.

Are Diet Sodas Safe and Effective?

diet soda dangerousAs you might expect these studies have caused quite a bit of controversy. Some experts have embraced these studies and have concluded that health professionals should stop recommending diet sodas as a safe and effective alternative to sugar-sweetened sodas.
Others have been unwilling to change their recommendation of diet sodas for people who are obese and/or diabetic. Their rationale is 3-fold:

  • These studies merely show that diet soda consumption is associated with weight gain, diabetes, heart disease, stroke and Alzheimer’s. Association does not prove causation, so their viewpoint is that there is no conclusive proof that diet sodas cause weight gain and health risks.
  • The obesity epidemic is a major health crisis, and consumption of sugar-sweetened beverages plays an important role in weight gain.
  • They are convinced that most people are so addicted to the sweet taste of sugar that they would be unwilling to switch to calorie free options like water or herbal teas.

In short, they are desperately clinging to the hope that substituting diet sodas for sugar-sweetened sodas will put a dent in the obesity crises because they don’t believe there are any other viable options.

What Do These Studies Mean For You?

I side with those experts who have looked at the data from the opposite perspective and concluded there is no convincing evidence that diet sodas are either safe or effective.

If the conversation were just centered around weight gain, diabetes, and heart disease, this could be considered an academic discussion. One could argue that diet sodas might have some benefit, and, at the worst, would have the same health risks as the regular sodas they replaced.

However, the possibility that diet sodas may increase the risk of stroke and dementia is a game-changer in my mind. That’s because consumption of sugar-sweetened sodas does not appear to increase the risk of either stroke or dementia. If true, that means that substitution of diet sodas for sugar-sweetened sodas is not a neutral substitution. It could cause serious harm.

With no good evidence that diet sodas help people control weight and the possibility that they may have serious health risks, it is difficult to see how anyone in good conscience can continue to recommend diet sodas in place of regular sodas.

My recommendation is to substitute water and other unsweetened beverages for the sugar sweetened beverages you are currently consuming. If you crave the fizz of sodas, drink carbonated water. If you need more taste, try herbal teas or infuse water with slices of lemon, lime, or your favorite fruit. If you buy commercial brands of flavored water, check the labels carefully. They may contain sugars or artificial sweeteners. Those you want to avoid.

So, is diet soda bad for you?  Well, it’s not good for you.

The Bottom Line

  • This January an international consortium of experts reviewed all of the pertinent literature and concluded: “The available evidence…does not consistently demonstrate that artificially-sweetened beverages are effective for weight loss or preventing metabolic abnormalities. The absence of evidence to support the role of artificially sweetened beverages in preventing weight gain and the lack of studies on other long-term effects on health strengthen the position that artificially-sweetened beverages should not be promoted as part of a healthy diet.”
  • This April a study was published reporting that people consuming at least one diet soda per day over a 10-year period were 3X more likely to have a stroke or develop dementia (primarily Alzheimer’s disease) than people consuming no diet sodas. Two other studies on the effect of diet sodas on the risk of stroke have come to similar conclusions.
  • We cannot yet say definitively that diet sodas cause stroke and dementia. Further research is clearly needed to test these associations. However, at this point it is safe to say there is no convincing evidence that diet sodas are either safe or effective.
  • With no good evidence that diet sodas help people control weight and the possibility that they may have serious health risks, it is difficult to see how anyone in good conscience can continue to recommend diet sodas as a substitute for sugar-sweetened sodas.
  • My recommendation is to substitute water and other unsweetened beverages for the sugar sweetened beverages you are currently consuming. If you crave the fizz of sodas, drink carbonated water. If you need more taste, try herbal teas or infuse water with slices of lemon, lime, or your favorite fruit. If you buy commercial brands of flavored water, check the labels carefully. They may contain sugars or artificial sweeteners. Those you want to avoid.

Stress and Jaw Pain

Get Rid Of Jaw Pain Forever

Author: Julie Donnelly, LMT – The Pain Relief Expert

Editor: Dr. Steve Chaney

 

In this article we will show a connection between stress and jaw pain. 

stress and jaw painStress is a part of everyone’s life, but the way you handle it makes a huge difference.  People think of stress coming from challenges like divorce, bills, etc., but it can also come from happy situations. Positive life changes such as getting married or having a baby can also cause stress.

For some people, the solution to stress is to take a yoga class or practice tai chi regularly.  For others, running, exercising, or listening to music eases their mind.

In my Muscular Therapy office, people frequently tell me “I hold my stress in my shoulders,” or “…in my back.” However, a common stress reaction is to clench your teeth tightly. Actually, people hold stress all over their body, from headaches and clenched jaws to foot pain. I want to discuss how clenching your jaws is a common cause of TMJ. Fortunately, it’s a condition that is easy to treat by yourself.

Stress And Jaw Pain

jaw painJaw pain is commonly caused by a shortening of the masseter muscle. The masseter muscle (circled on graphic) is the muscle that contracts to enable you to chew your food.  Normally, as you chew the muscle shortens and then lengthens as you put more food into your mouth.  How can stress and jaw pain be related?  If you are under stress and your teeth are clenched, you miss the lengthening movement. This imbalance causes the muscle to shorten.

Put your fingers on your cheeks so you are pressing into your back teeth.  Now, clench your teeth and you’ll feel the muscle bulge.  If you clench your teeth when you sleep or you tend to clench your teeth when you are upset, you are setting yourself up for TMJ.

Stress And Jaw Pain (TMJ)

TMJ (Temporomandibular Joint) pain is a condition where your jaw bone rubs or “clicks” over the bone that is just in front of your ear. It is painful, and over time it will damage the bones. When you are under stress and clenching your teeth, you are shortening your masseter muscle. A phenomenon called “muscle memory” will cause the muscle to actually get stuck in the shortened position. The now-shorter muscle prevents you from opening your jaw completely.  For example, when you yawn.  As you are trying to yawn, your jaw flips over the bone and it hurts.

Several years ago, I had a client who had such tight masseter muscles that a dental surgeon was going to sever them so she could open her mouth.  This is a terrible solution because it would mean her mouth would hang open for the rest of her life. Fortunately for this client, she had to get medical approval before she could have the surgery.  When Dr. Cohen (the doctor I worked with) felt her masseter muscles, he refused to sign the permission form. He told her that she had to see me first.  Fortunately, I was there at the time.  It took just 30 minutes for me to release the spasms and teach her how to do the treatment.  At the end of the session she was pressing into both masseter muscles and opening her mouth.  She did it easily and without pain!  She started to cry because she came within one day of having this unnecessary surgery.

Her life was changed by just a simple self-treatment!

Self-Treatment For TMJ Pain

stress and jaw pain reliefHere is how to administer TMJ pain relief to yourself.  Place your fingers as shown in the picture to the left.  Clench your teeth so you can feel the muscles bulge.

Apply deep pressure on just one side for 5 seconds. Then release that pressure and apply deep pressure to the opposite side for 5 seconds. Go back and forth until it doesn’t hurt anymore.  Then find a different “hot spot,” and repeat.  Continue doing this until you can’t find any more tender points on your muscle and jaw.

To stretch the masseter muscle, just press deeply into the original point on the muscle pain free living book coverand slowly open your mouth wide.

Hopefully, you can now see the connection between stress and jaw pain.  Stress is a killer, and is the cause for pain all over your body.  It’s also important to find the cause of stress and do all that is necessary to resolve it.

My book, “Treat Yourself to Pain-Free Living,” will show you how to self-treat painful spasms throughout your body.  Don’t let the pain caused by stress stop you in your tracks. You can become pain-free, and then go and enjoy a yoga class to release stress from your life.

Wishing you well,
