What You'll Learn
Increased risk of stroke
While diet pop is often seen as a healthier alternative to regular soft drinks, it has been linked to a number of adverse health effects. One of the most concerning is the potential increased risk of stroke, particularly in women.
Several studies have found a link between the consumption of diet drinks and an increased risk of stroke. One study, in particular, found that drinking two or more diet beverages per day was associated with a higher risk of stroke, heart attacks, and early death in women over 50, especially in obese and African American women. The study also revealed that small-artery occlusion, a type of stroke caused by the blockage of the smallest arteries in the brain, was 2.5 times more likely to occur in women who had no heart disease or diabetes but were heavy consumers of diet drinks.
Another study, which analyzed data from over 81,000 postmenopausal women, found that daily consumption of two or more artificially sweetened beverages increased the likelihood of having a stroke by 23% and developing heart disease by 29%. This study also noted that the risks were higher for certain groups, including obese women and African American women.
While these studies suggest a strong association between diet drink consumption and the risk of stroke, it is important to note that they are observational and cannot prove a direct cause-and-effect relationship. However, the consistent findings across different studies indicate a potential link that warrants further investigation.
The exact mechanism behind the possible link between diet pop and stroke risk is not fully understood. Some researchers speculate that it may be related to the artificial sweeteners commonly found in these drinks. These sweeteners have been shown to affect the gut microbiome, which plays a crucial role in overall health, including cardiovascular health. Additionally, some artificial sweeteners may impact insulin and blood glucose levels, which could indirectly influence stroke risk over time.

Adverse effects on gut health
Drinking diet pop or soda is believed to have several adverse effects on the body. One of the main concerns is its impact on gut health.
The artificial sweeteners commonly found in diet soda, such as aspartame, acesulfame potassium, and sucralose, have been linked to negative effects on the gut microbiome. The gut microbiome refers to the community of beneficial bacteria in the digestive tract, which plays a crucial role in immune function, nutrient absorption, and heart health. While research is ongoing, some studies suggest that these artificial sweeteners can disrupt the balance of this microbiome, leading to potential health issues.
One study found that individuals who consumed artificial sweeteners experienced increases in both insulin and blood glucose levels. This can lead to insulin resistance, which is a risk factor for Type 2 diabetes. Additionally, the consumption of artificial sweeteners has been associated with an increased risk of metabolic syndrome, which can increase the likelihood of developing heart disease if left untreated.
Furthermore, the highly acidic nature of diet soda can contribute to tooth erosion. While it does not increase the risk of cavities like sugary drinks, studies have shown that it can affect the surface roughness of tooth enamel.
The impact of diet soda on gut health is a growing area of research, and while some studies have found links to adverse effects, more comprehensive investigations are needed to fully understand the mechanisms and long-term consequences of regular consumption.

Increased risk of type 2 diabetes
While diet pop contains no sugar or calories, some research has found an association between its consumption and an increased risk of type 2 diabetes. This is because the artificial sweeteners found in diet pop may negatively affect your gut microbiome, which is the community of beneficial bacteria in your digestive tract.
A 2013 study showed that sucralose, an artificial sweetener, can raise blood sugar higher when carbohydrates are consumed later compared to those who did not consume any sucralose. Sucralose has also been found to increase insulin levels, and frequent rises in insulin have been linked to insulin resistance and an increased risk of type 2 diabetes. Another study found that people with obesity who switched to diet soda were likely to consume more calories in food than those who drank regular soda.
Furthermore, a 2018 study of 2,019 people who did not initially have diabetes found that 368 participants had developed type 2 diabetes by the follow-up. The study also showed that participants with a higher body mass index (BMI) were at an increased risk of diabetes and were more likely to be drinking diet soda. Even when using statistical methods to remove the influence of BMI, daily diet soda consumption was a significant predictor of developing diabetes among those participants who were overweight or obese at baseline.
Additionally, a Multi-Ethnic Study of Atherosclerosis (MESA) found that daily consumption of diet soda was associated with a 67% greater relative risk of type 2 diabetes compared to nonconsumption. While these studies suggest a link between diet pop and type 2 diabetes, it is important to note that they do not establish causality, and more research is needed to confirm these findings.

Negative impact on bone health
While diet soda may seem like a healthier alternative to regular soda, it may not be as harmless as it seems. Research has linked the consumption of diet soda to a range of adverse health effects, including potential negative impacts on bone health.
Several studies have examined the relationship between soft drink consumption and bone health, particularly in older women. The Framingham Osteoporosis Study found that colas, but not other carbonated beverages, were associated with low bone mineral density in older women. This study measured bone mineral density (BMD) at the spine and hip sites in a large number of participants and adjusted for various factors, including body mass index, age, physical activity, and dietary intake. The results suggested that the caffeine and phosphoric acid in colas may be contributing factors to the decreased BMD.
Another study, the Women's Health Initiative, followed 72,342 postmenopausal women and analyzed the relationship between soda intake and the risk of hip fracture over a 16-year period. While the results of this study are not yet known, it adds to the growing body of research investigating the impact of soft drinks on bone health.
The potential negative impact of diet soda on bone health is particularly concerning given the role of bone mineral density in osteoporosis and the risk of fractures. As bone mineral density decreases, the risk of fractures increases. Osteoporosis is a condition characterized by weak and brittle bones, and it is more prevalent in older adults. Therefore, the consumption of diet soda may be a contributing factor to the development or progression of osteoporosis.
While more research is needed to fully understand the relationship between diet soda and bone health, the current evidence suggests that excessive consumption may have adverse effects. It is important to note that the impact of diet soda on bone health may be influenced by various factors, including age, sex, dietary habits, and overall health. Therefore, further studies are required to understand the complex relationship between diet, lifestyle, and bone health.

Potential harm to dental health
While diet soda may seem like a healthier alternative to regular soda, it may not be as harmless as it seems, especially if you're drinking several servings per day. One of the potential adverse effects of consuming diet soda is the harm it can potentially inflict on your dental health.
Diet soda is highly acidic, and this acidity can contribute to tooth erosion. A test-tube study found that both regular and diet soda significantly affected the surface roughness of tooth enamel, indicating their potential to cause tooth erosion. Another study suggested that diet drinks slightly increased the risk of dental erosion in US adults, but more research is needed to confirm this. It is important to note that while damage to dental enamel from acidity is a concern, it is not the same as an increased risk of cavities caused by sugar content. In fact, a 2020 study found that diet soda did not promote dental cavities among children.
The artificial sweeteners found in diet soda can also have adverse effects on your dental health. These sweeteners can negatively affect your gut microbiome, which is the community of beneficial bacteria in your digestive tract. A disrupted gut microbiome can impact various aspects of health, including immune function, nutrient absorption, and heart health. Additionally, some artificial sweeteners, such as aspartame, have been linked to headaches and migraines, particularly in individuals with neurological or psychiatric conditions.
Furthermore, the caffeine content in some diet sodas can also impact dental health. Excessive caffeine intake has been associated with negative effects on bone health, which can extend to the bones in your jaw and affect your dental structure. While diet soda may not have the same cavity-causing effects as sugary drinks, overconsumption can still lead to potential dental issues.
While quitting any habit can be challenging, being aware of the potential harm to your dental health from regular and long-term consumption of diet soda can help inform your decisions and encourage moderation or alternative beverage choices to maintain optimal dental and overall health.
