Drinking two or more diet drinks a day has been linked to a higher risk of strokes, heart attacks, and early death in women over 50, according to a study. The study, which focused on postmenopausal women with no history of diabetes or heart disease, found that those who consumed two or more artificially sweetened beverages each day were 31% more likely to have a clot-based stroke. While the results do not suggest that diet drinks directly cause strokes, the association has raised concerns about how artificial sweeteners may be affecting the body.

What You'll Learn
Obese and African-American women are at a higher risk of strokes
A study published in the UW School of Public Health found that diet drinks are linked to an increased risk of stroke, particularly in obese and African-American women. The study, which included more than 80,000 postmenopausal US women, found that consuming two or more diet drinks per day was associated with a 23% increased risk of all strokes in women. Obese and African-American women who consumed this amount of diet drinks had an even higher risk of stroke, with their risk of small artery occlusion more than doubling. Small artery occlusion is a specific type of ischemic stroke that occurs when blood flow is blocked in a very small arterial vessel.
Obese and African-American women are already at a higher risk of strokes due to various factors. Obesity is a well-known risk factor for stroke, and obesity rates have been steadily increasing in the United States. In 2011-2012, the prevalence of obesity in the US was 16.9% in youth and 34.9% in adults. Obese individuals have a higher risk of hypertension, diabetes, and other metabolic issues, which are all risk factors for stroke. In addition, cultural determinants may also play a role in the higher prevalence of obesity among African-American women.
African-American women also face additional stroke risk factors beyond obesity. Hypertension, or high blood pressure, is more prevalent among African-American women and is a significant risk factor for stroke. Diabetes is another risk factor that is more common among African-American women. These risk factors can interact with obesity to further increase the risk of stroke in this population.
While the exact reasons for the link between diet drinks and stroke risk are not yet known, researchers have proposed several theories. One theory suggests that people who are overweight or have diabetes may be more likely to choose diet drinks over sugary ones, and their heightened stroke risk may result from these underlying health issues rather than their beverage choice. Additionally, artificial sweeteners may contribute to weight gain and cravings for sugary, high-calorie foods, which could indirectly increase the risk of stroke.
It is important to note that the study on diet drinks and stroke risk was observational and could not establish a cause-and-effect relationship. Further research is needed to confirm the findings and guide clinical recommendations. In the meantime, water is recommended as the best alternative to sugary drinks, as it does not contain artificial sweeteners or added sugars.

Diet drinks and artificial sweeteners
Several studies have found a link between drinking diet beverages and an increased risk of stroke, particularly in postmenopausal women. However, it is important to note that these studies are observational and cannot prove a direct cause-and-effect relationship.
One study, published in the journal Stroke, found that women who drank two or more artificially sweetened drinks per day had a 23% higher risk of any type of stroke and a 31% increased risk of having a clot-based stroke, specifically in the smaller blood vessels of the brain. This type of stroke, called small-artery occlusion, is caused by the blockage of the smallest arteries inside the brain and is a common subtype of ischemic stroke. The study also found that the risk was highest for obese and African American women, who were 2.5 times more likely to experience this type of stroke if they were heavy consumers of diet drinks.
Another study, led by researchers from the Albert Einstein College of Medicine, found a modest increased risk for stroke among women who consumed diet beverages. However, the researchers cautioned that it is too early to draw definitive conclusions and that more studies are needed to replicate the findings.
While the exact reasons for the link between diet drinks and stroke risk are not yet known, some researchers have suggested that artificial sweeteners may compromise the body's ability to break down glucose properly, leading to impaired glucose control, which is a risk factor for diabetes, heart disease, and circulatory problems. Additionally, people who are overweight or have diabetes may be more likely to choose diet drinks, and their heightened stroke risk may be related to these underlying health conditions rather than their beverage choice.
It is worth noting that the studies on this topic have focused on the consumption of diet drinks, such as diet soda and diet fruit juice, and have not specifically examined the impact of artificial sweeteners in isolation. As such, more research is needed to understand the specific role of artificial sweeteners in stroke risk. In the meantime, some experts recommend reducing the intake of sugary drinks and diet drinks, instead encouraging the consumption of water or other low-sugar alternatives.

Diet drinks and diabetes
While there is no direct evidence that diet drinks cause strokes, studies have found a link between their consumption and an increased risk of stroke. One such study, published in Stroke, found that diet drinks were particularly associated with blood clots in the small arteries. The study also found that the risk was higher for certain groups of women, including African-American women and obese women. However, it is important to note that this study was observational and could not prove cause and effect.
Turning to the topic of diet drinks and diabetes, there are a few key points to consider. Firstly, while diet drinks are often viewed as a healthier alternative to sugary drinks, they may not be the best option for people with diabetes or those trying to prevent it. This is because diet drinks have been linked to weight gain and metabolic syndrome, which can worsen diabetes or increase the risk of developing type 2 diabetes. Research has shown that participants who drank diet soda on a daily basis had nearly quadruple the waist gain compared to those who did not consume it. Additionally, a 2018 study found that consuming more than four cans of diet soda per week was associated with a more than twofold risk of proliferative diabetic retinopathy (PDR) in people with diabetes. PDR is an advanced form of diabetic eye disease.
It is worth noting that some studies have suggested that drinking diet sodas may lead to low blood sugar due to an imbalance in insulin secretion. However, the results of this research have been inconclusive. Furthermore, while artificial sweeteners in diet sodas do not directly raise blood sugar, they may still promote health risks by affecting the balance of healthy bacteria in the intestines, which can indirectly impact insulin sensitivity and appetite hormones.
On the other hand, some doctors recommend switching to diet soda for people with type 2 diabetes. This is because it is generally accepted that soda with artificial sweeteners does not raise blood sugar. The American Diabetes Association recommends that people with diabetes primarily drink water, unsweetened iced or hot tea, and sparkling or infused water, which have no calories and few nutrients. However, they also suggest that milk and 100% fruit juices can be better choices due to the nutrients they provide, although these should be limited because of their natural sugar content.
In conclusion, while diet drinks may not directly cause strokes or directly impact diabetes, they have been linked to an increased risk of stroke and may worsen diabetes or increase the risk of developing type 2 diabetes due to their association with weight gain and metabolic syndrome. Therefore, it is advisable to consume them in moderation and prioritize healthier alternatives whenever possible.

Diet drinks and heart disease
Several studies have found a link between drinking diet beverages and an increased risk of stroke and heart disease. One study, in particular, found that women who consumed two or more diet drinks per day were 23% more likely to have any type of stroke and 31% more likely to have a clot-based stroke. The study also found that these women were 29% more likely to develop coronary heart disease and 16% more likely to die from any cause.
It is important to note that these studies are observational and cannot prove cause and effect. There may be other factors contributing to the increased risk of stroke and heart disease in these individuals. For example, people who choose diet drinks may already be at a higher risk for stroke due to obesity or diabetes. Additionally, the artificial sweeteners in diet drinks may have negative effects on the body, such as impairing the body's ability to break down glucose properly, which can lead to diabetes and heart disease.
While the exact mechanism is not yet understood, the link between diet drinks and an increased risk of stroke and heart disease is concerning. More research is needed to determine the specific effects of artificial sweeteners on health and to develop clinical recommendations for the consumption of diet drinks. In the meantime, it may be prudent to limit the intake of diet drinks and artificially sweetened beverages, especially for those at risk for stroke and heart disease.
Water is always the best choice for hydration, but if you're looking for something with more flavor, there are other options besides diet drinks. Try flavoring flat or sparkling water with a splash of fruit juice, or add frozen fruit, cucumber, or crushed mint. Unsweetened tea is another option, and some people find that it provides a similar level of satisfaction to soda without the added sugar or artificial sweeteners.

Diet drinks and early death
Several studies have found a link between drinking two or more diet drinks per day and an increased risk of stroke, heart attacks, and early death in women over 50. The risk was highest for obese and African American women, who were 3.93 times and four times more likely, respectively, to have a clot-based stroke than Caucasian women. The study also found that women who consumed two or more diet drinks per day were 23% more likely to have any type of stroke, 29% more likely to develop coronary heart disease, and 16% more likely to die from any cause.
The reasons for these links are not yet fully understood, and researchers caution that the studies were observational and cannot prove cause and effect. One theory is that people who are overweight or have diabetes may switch from sugary drinks to diet drinks, and their heightened stroke risk may be due to their underlying health conditions rather than their beverage choice. Another theory suggests that artificial sweeteners may compromise the body's ability to break down glucose properly, leading to diabetes and an increased risk of circulatory problems.
The American Heart Association (AHA) recognizes that diet drinks can help replace high-calorie, sugary beverages, but they recommend water (plain, carbonated, or unsweetened flavored) as the best no-calorie drink option. While the studies do not prove causation, they raise concerns about the potential health risks associated with high consumption of diet drinks. More research is needed to understand the specific effects of artificial sweeteners and the mechanisms underlying the observed associations.
It is worth noting that the studies focused on postmenopausal women, and the results may not be generalizable to younger women or men. Additionally, the studies did not differentiate between specific brands of drinks or types of artificial sweeteners. Further research is needed to determine whether certain artificial sweeteners are more or less associated with adverse health outcomes.
In conclusion, while the exact mechanisms remain unclear, the current evidence suggests that excessive consumption of diet drinks may contribute to an increased risk of stroke, heart attacks, and early death, particularly in older women. As a result, it may be prudent to limit the intake of these beverages and prioritize water and other healthier alternatives until more definitive conclusions can be drawn.
