Diet Soda And Diabetes [UK]: Is Diet Soda Good For Diabetes In 2023?

As a person with diabetes, it’s essential to pay close attention to what you consume, especially when it comes to sugar content. While diet soda may seem healthier due to its low or zero-calorie content, you still need to consider the potential risks of artificial sweeteners.

Although diet sodas may serve a purpose as a short-term replacement for sugar, water should always be your go-to drink when managing diabetes.

This article will help you make an informed choice about your beverage intake and how best to manage your blood glucose levels if you consume daily soda.

What Is Diet Soda?

Diet soda is a popular beverage choice for those looking to cut down on sugar and calories. Unlike sugar-sweetened beverages, typically loaded with sugars and high in calories,^[1] diet soda is sweetened with artificial sweeteners. By choosing diet soda, you can enjoy a refreshing drink without the added sugars that can negatively affect your blood glucose levels and overall health.

One of the primary features of artificially sweetened beverages is that they are typically calorie and carbohydrate-free. This makes it an attractive option for those with diabetes or who want to lower their calorie intake for weight reasons. Artificial sweeteners such as aspartame, sucralose, and saccharin^[2] are often used in these beverages to mimic the taste of sugar while contributing minimal or no calories.

When considering whether artificially sweetened beverages suit you, it’s essential to understand potential health risks, your unique dietary needs, and the importance of moderation in consumption. Remember to consult a registered dietitian or a healthcare professional certified in diabetes education for personalized advice on managing your blood sugar levels. 

Does Diet Soda Raise Blood Sugar?

So does diet soda raise blood sugar? The answer is that diet soda doesn’t directly impact your blood sugar^[3] or A1C levels. However, you should still be cautious about other factors indirectly affecting your blood sugar levels.

In a study, researchers found a significant link between diet soda consumption and the development of high blood sugar levels and belly fat,^[4] two indicators of metabolic syndrome.^[5] 

Another 2022 study highlighted the adverse effects^[6] of numerous sweeteners on the gut microbiome, adversely affecting glucose tolerance over time. The worst offender in this study was sucralose, although saccharin, aspartame, and stevia affected the gut microbiome to some degree.

And, while aspartame may be found in carbonated beverages with just as many carbohydrate calories as sugar, far less is needed to achieve desired sweetness; thus, it is not known to impact glycemic control. Two clinical trials found that those who consumed foods sweetened with aspartame affected glucose and insulin levels, although the results of these and other studies were contradictory.

It is always important to be mindful of your overall diet and lifestyle choices to manage your diabetes effectively. Here are a few tips to help you make better choices regarding diet soda and blood sugar management:

• Opt for water, unsweetened tea, or black coffee when possible, as they will not impact your blood sugar levels.
• Limit your overall consumption of artificially sweetened products, as some individuals may not be able to manage blood glucose levels effectively in response to these sweeteners.
• Stay active and maintain a healthy weight to reduce the risk of developing conditions like metabolic syndrome.

Remember, you can make informed choices about your health and diet. 

Diet Soda And Diabetes

As we have discussed, the risks associated with diet soda mean it is no magic bullet for people with diabetes. 

Diet soda has long been marketed as a healthier alternative to regular soda, especially for people with diabetes who must watch their sugar intake.

 However, studies have shown that diet soft drinks may increase the risk of developing type 2 diabetes. This is because diet soda contains artificial sweeteners, such as aspartame and sucralose, which can disrupt the body’s ability to regulate blood sugar levels and insulin response. In addition, the sweet taste of diet soda can also trigger cravings for sugary foods —leading to overeating and weight gain, which are both risk factors for diabetes.

So, is diet soda bad for diabetes? More research is needed to understand the link between diet soda and diabetes fully. However, people with diabetes should be cautious about consuming these beverages. Instead, they should opt for healthier alternatives such as water, unsweetened tea, or sparkling water with a splash of fruit juice. Small changes to one’s diet and lifestyle can significantly impact diabetes management and overall health.

Risks Of Drinking Diet Soda

Although consuming diet soda may seem like a better alternative for managing blood glucose levels than drinking sugary drinks, it comes with its own risks. One major concern is that diet soda consumption correlates with an increased risk of cardiovascular disease,^[7] although there is no evidence they increase^[8] blood pressure. These conditions can be particularly concerning for people with diabetes, who are already at a higher risk for heart problems.^[9]

Drinking diet soda may also be linked to weight gain rather than loss. Although the drinks are low in calories, research has shown they can stimulate your appetite.^[10] This can lead to overeating and, ultimately, weight gain. This can be particularly problematic for people with diabetes, as maintaining a healthy weight is essential for managing the condition. 

Alternative Drinks For Diabetes

As a person who struggles with sugar cravings and managing blood glucose levels, you may be looking for healthier alternatives to diet soda or natural sweeteners to use, and luckily, there are several options to choose from. Here are a few suggestions that taste great and provide essential nutrients to support your health.

Water Infused With Fruits Or Herbs

Staying hydrated is crucial for everyone, especially those with diabetes. Infusing water with fruits or herbs adds flavor and enjoyment and has minimal impact on your blood sugar levels. Feel free to get creative by mixing and matching different fruits, such as lemon, cucumber, strawberry, or mint. The result is a refreshing, low-calorie drink to keep you hydrated throughout the day.

Unsweetened Iced Tea

Unsweetened iced tea is a refreshing beverage. Opt for herbal teas or green tea, which contain antioxidants that may benefit your overall health. Remember to avoid adding any sugars. If needed, you can lightly sweeten your iced tea with a natural, low-calorie sweetener like monk fruit.

Vegetable Juice

Vegetable juice is a nutrient-dense alternative to diet soda. Tomatoes, carrots, and leafy greens are excellent choices for juicing. Just be mindful of portion sizes and remember to consume vegetable juice without any added sugars. 

Low-fat Milk Or Unsweetened Almond Milk

Low-fat milk or unsweetened fortified almond milk can be a nutritious alternative, providing you with essential nutrients^[11] such as calcium, protein, and vitamin D. However, keep an eye on portion sizes, as milk does contain some natural sugars. 

Choosing alternative drinks or supplements low in carbohydrates and sugars can help you manage your diabetes effectively. Enjoy exploring these refreshing alternatives to diet soda and quench your thirst for a healthier lifestyle.

The Bottom Line

The impact of foods and beverages on blood sugar levels is important to consider when managing diabetes. Although the evidence may be contradictory about diet soda raising blood sugar levels, it contains artificial sweeteners that might not be the best for blood sugar control. These have been linked to a higher risk of type 2 diabetes, some with weight gain and others with metabolic syndrome. 

Both diet and regular soda intakes have also been linked to increased risks of diabetes and metabolic syndrome. Therefore, it is recommended to opt for healthier alternatives such as water, low-calorie flavored drinks, and teas and coffee without sweeteners. Overall, prioritizing healthier beverage options can better manage diabetes and overall health.
