Same goes for the word “diet”.

Whether it’s diet snacks or diet soda, those fewer calories have their price.

Diet Soda And Heart Disease

Diet soda is advertised as a healthy substitute for regular soda because it has fewer calories. But the story doesn’t end there.

One in five Americans United States admit to consuming diet drinks every day (1).

This very statistic is what sparked the curiosity of Dr. Ankur Vyas, a fellow in cardiovascular disease at Univesity of Iowa Health Care Hospitals and Clinics.

Despite the popularity of diet drinks, Dr. Vyas noticed that there was a lack of data concerning their health consequences. This is particularly true when it comes to cardiovascular health.

During his study, he discovered that people who drank “two or more cans of diet soda a day were 30% more likely to have a cardiovascular event (e.g. heart attack) and 50% more likely to die of a heart-related disease than someone who drank none.”

“This is one of the largest studies on this topic, and our findings are consistent with some previous data, especially those linking diet drinks to the metabolic syndrome,” said Dr. Vyas.

Long Time Coming

In the Women’s Health Initiative Observational Study, Dr. Vyas and his team observed 60,000 postmenopausal women over the course of nine years.

First, participants tracked and reported their consumption of 12-ounce diet sodas and fruit drinks for three months.

They were then divided into four groups:

  • 2 or more drinks a day
  • 5-7 drinks per week
  • 1-4 drinks per week
  • 0-3 drinks per month

Their health records were examined 8.7 years later to bright to light their history of disease and medical interventions.

Theses included:

  • Coronary heart disease
  • Congestive heart failure
  • Heart attack
  • Coronary revascularization procedure
  • Ischemic stroke
  • Peripheral arterial disease
  • Cardiovascular death

8.5% of the women who drank two or more diet drinks a day experienced one or more interventions over the course of the study. This compares to 6.9% in the five-to-seven diet drinks per week group, 6.8% in the one-to-four drinks per week group, and 7.2% in the zero-to-three per month group.

Women in the 2 or more a day group were significantly younger and had higher BMIs than women in the other groups, meaning that the diet soda was causing health issues in these women at an accelerated rate. They were also more likely to suffer from diabetes and high blood pressure.

Although the study unearthed some very alarming information, no official conclusion has been made by the research team.

“Based on these and other findings we have a responsibility to do more research to see what is going on and further define the relationship,” Vyas explained. “This could have major public health implications.”

Similar Studies

In 2012, University of Miami and Columbia University researchers followed 2,500 New Yorkers over the age of 40 for 10 years. All the participants had never experienced a stroke prior to the study (2).

Like the Iowa study, participants were instructed to write down their soda drinking habits. They also had to report health problems, hospitalizations, and new medication once a year during a phone interview.

Researchers found that diet soda drinkers were more likely to have had a stroke or heart attack, or to have died from vascular disease over the course of the study. They were also more likely to be former smokers and to suffer from high blood pressure. They even had, on average, higher blood sugar and larger waistlines than their regular soda-drinking counterparts.

Those who drank it every day were 36% more likely to develop metabolic syndrome and had a 67% higher risk of developing diabetes.

In comparison, participants who drank regular soda were more likely to smoke and eat more carbohydrates. However, they were less likely to have diabetes or high cholesterol.

Researchers concluded that soda consumption, both diet and regular, were equally linked to cardiovascular disease risk factors.

In a similar study, researchers at the Karolinska Institute in Sweden examined the effect of daily non-diet soda consumption (3).

After examining 42,400 men over 12 years, they found that men who drank two or more 200ml servings had a 23 percent higher risk of developing heart failure.

They also proved that in 3 604 cases, soda consumption was a direct factor in the development of heart failure. Of these cases, 509 died as a result of the condition.

Not So Sweet

Some of the medical conditions mentioned above are partially caused by aspartame, saccharin, and sucralose, which are artificial sweeteners used in diet products (4).

These sweeteners have a more intense flavor than natural sugars. Hence, over time, they may diminish your ability to taste sweetness.

They also have the same detrimental effects as regular sugar, including insulin resistance, weight gain, high blood pressure, elevated glucose levels, and raised cholesterol. These conditionsput you at risk for heart disease, stroke, and diabetes.

So next time you reach you reach for a diet soda, trade it for some organic fruit juice or healthy tea.
