40 Side Effects of Drinking Too Much Soda

A single 12-ounce can of soda packs an average of 39 grams of sugar—that’s more than three times the amount you’d get in a Krispy Kreme glazed donut, and yet, we’re still drinking the stuff by the gallon. The CDC reports that 49% of adults in the U.S. drink at least one regular soda or other sweetened beverage per day, which adds up to a ton of calories, sugar, and extra weight per year.

While soda sweetened with sugar or high-fructose corn syrup comes with its own risks—from increased risk of ailments like diabetes and tooth disease—the diet stuff isn’t much better. In fact, research suggests that diet soda drinkers have an increased likelihood of weight gain and increased waist measurements. Not great news. So, if you’re eager to get on the right track toward healthier habits, check out these potential side effects of drinking soda that will make you quit the sweet stuff for good. Then, be sure you stock up on The 7 Healthiest Foods to Eat Right Now.

It probably comes as no surprise to you that drinking soda has been linked to obesity. While this may be partially due to the types of high-calorie foods that tend to accompany sodas and fizzy drinks, a single can of soda packs 140 calories but is almost guaranteed to be of no help when it comes to your hunger. Add a soda to every meal for 30 days and you could be gaining more than three pounds by the time the month is done. Related: Here’s the one drink that’s worse for you than soda.

Think switching to diet soda is doing you any favors in terms of your blood sugar? Think again! Both regular and diet soda have been linked to an increase in type 2 diabetes. The sugar spike you get from soda forces the body to transform that sugar into fat in your liver. Over six months, the fat deposits in your liver may have increased by as much as 150%, increasing your risk factor for diabetes along the way. Similarly, research published in the Yale Journal of Biology and Medicine suggests that artificial sweeteners may actually increase your cravings for real sugar, putting you at greater risk for diabetes. Lower your risk of chronic disease starting today by avoiding these 50 worst foods for diabetes.

A single 12-ounce can of soda contains almost ten packets of sugar, coating your teeth and gums every time you crack open a can. In fact, multiple studies have shown just how deleterious soda can be to your teeth; left in soda for sufficient time, human teeth will actually dissolve. Unfortunately, despite the claims pushed by some toothpaste companies, tooth enamel can’t be regrown after it’s eroded—once it’s gone, it’s gone for good.

If you feel like your gum line is receding faster than your hair, your soda habit might be to blame. The sugars, preservatives and artificial colorings found in your average soda can get trapped beneath your gums. If that area isn’t cleaned thoroughly, bacteria feeds on the trapped particles causing deterioration, infection, and the destruction of gum tissue, which is nearly impossible to regenerate. Fortunately, giving up soda now can reduce your risk of receding gums and keep that smile healthy and bright as you age. Related: 25 Foods You Had No Idea are Good for Your Teeth

Sporting a spare tire? Blame your soda habit. The refined sugar in soda is quickly absorbed, causing your blood sugar to spike. This sudden surge in blood sugar triggers the production of insulin and can turn that sugar into fat—particularly those pounds around your waist—in no time.

Often called the most excruciating pain this side of childbirth, kidney stones are the result of an accumulation of minerals in the kidneys over time, which eventually pass through the urethra. Unfortunately, those with regular soda habits are at an increased risk for this unpleasant condition; both excessive sugar consumption and dehydration are associated with increased risk of kidney stones, and soda just so happens to contribute to both.

You might not be the only one in your family affected by your soda consumption. The plastic bottles soda comes in often contain BPA, a chemical used to harden plastics, which has been shown to contaminate substances that come in contact with it. The result? Potential behavioral problems in your offspring—researchers at Columbia University, the National Center for Environmental Health, and the CDC have found a link between exposure to BPA and an increased risk of behavioral health issues.

Your risk for stroke increases with each sip of soda you take. Soda is directly responsible for increased fat stores in the body, some of which can cause hardening of your arteries, including the ones close to your brain, increasing your stroke risk.

Drinking sodas is directly linked to unhealthy dietary habits. Researchers at the University of Bordeaux believe that sugar can be as addictive as illicit drugs, triggering the same reward centers in the brain as amphetamines and opiates. Unfortunately, this means that a single soda can have a snowball effect — that one drink makes you crave more and more, leading to out-of-control sugar consumption in no time. Soda is also generally served with less-than-healthy meals, like fast food, creating food associations that are difficult to break.

If you’re eager to keep your cardiovascular system strong as you get older, now’s the time to kick your soda habit for good. The Journal of General Internal Medicine suggests that soda drinkers are at a higher risk for stroke, heart attack, or death from vascular disease — in fact, even when controlling for other contributing factors to cardiovascular disease, like smoking, lack of exercise, and poor diet, soda drinkers were more likely to be affected by CVD than their abstinent counterparts.

Commit to lower cholesterol and a longer life by ditching those sodas from your diet today. A single can of soda has more sugar than you need in an entire day, and research published in the Journal of the American Medical Association suggests that a diet rich in sugar is linked to high levels of LDL, or “bad” cholesterol, and low levels of HDL, also known as “good” cholesterol. Combined with the sugars that sneak their way into your diet by way of other foods, you are risking your health with every sip of soda you take.

The gut bacteria living in your intestines can affect everything from your digestive health to your mental stability, making your gut health of the utmost importance to your overall well-being. Unfortunately, all that sugar in soda gives the bad bacteria in your belly plenty to feed on without providing much in the way of nutrition for the good bacteria that keeps you healthy. If you think diet soda is better, think again; a study conducted by the American Association for the Advancement of Science reveals your gut bacteria may react negatively and cause metabolic changes after being exposed to the artificial sweeteners in soda, putting you at increased risk for obesity, cognitive impairment, and digestive stress, among other health problems.

When your body’s leptin receptors are working effectively, they tell you when you’ve had enough to eat and help you maintain a healthy weight. However, when you drink soda, they’re not such a sensitive tool; the American Journal of Physiology states that overconsumption of fructose, a sweetener used in many sodas, has been linked to a shutdown in leptin response. Over time, this can lead to hunger, weight gain, diabetes, and put you at increased risk for a number of chronic illnesses.

Soda’s shelf-stability may come at a serious cost to your health and fertility. Certain citrus sodas contain brominated vegetable oil, also known as BVO, an additive that maintains soda’s flavor and appearance.

If you think you’re hydrating by drinking soda, you’re likely off-base. The caffeine in many sodas has a diuretic effect, causing dehydration if you don’t adequately supplement with extra water. Over time, this can lead to a slower metabolic rate, electrolyte imbalances, water retention, and even heart arrhythmia. Hydrate and get healthy with the Best-Ever Foods That Fight Fat!

Sneezing your way through allergy season? It might be your soda habit.

You won’t find happiness at the bottom of that can. Sodas are high in fructose, which can react negatively with the amino acids that accompany our happiness chemical, serotonin. Fructose damages those amino acids which then become unavailable, thereby reducing the amount of serotonin in the brain. Over time, this can contribute to your depression risk. Soda’s not so sweet after all, is it?

Drinking alcohol isn’t the only way you’re harming the health of your liver. The excess sugars in sodas have been linked to non-alcoholic fatty liver disease. Because sodas contain exorbitant amount of sweetener, the body cannot adequately process it, turning it into fat in the liver. Over time, this can lead to fatty liver, which can increase your risk of metabolic syndrome and early death over time. Get your liver healthier in no time with these Healthy Ways to Detox!

If you’re having trouble sleeping, it might be time to reevaluate your soda consumption.
