People’s quest for beverages like soda, energy drinks, diet soda, sweetened or unsweetened fruit juice, and cold drinks increases during the summer season. Consequently, the search for healthy beverages and the pros and cons of having any favourite drink increases. Because of rising health concerns, diet soda is becoming a popular beverage among people.

This drink has zero calories and suits several palates. That’s why some consider it a safe option for people with diabetes. In addition, unlike other beverages, it will not spike blood sugar immediately. But is it safe to drink for them, and does it help prevent diabetes? 

We address these concerns, including diet soda’s benefits and possible risks. And recipes for some alternative healthy summer drinks.

Is Diet Soda Safe for Diabetes?

Sugar needs to be kept low in people’s diets. Therefore, one may wonder if artificial sweeteners are a good alternative. Artificial sweeteners have negligible calories. Hence, people consider them good options. They are added extensively in soft drinks, and brands market them as a choice for health-conscious people.

Sadly, this is a marketing gimmick. Research claims that artificial sweeteners increase the risk of diabetes rather than controlling it. It further states possible side-effects of popular artificial sweeteners:

  • Saccharin: Bladder Cancer
  • Aspartame: Chronic Fatigue, Brain Tumour
  • Acesulfame: Carcinogenic (it has the potential to cause Cancer)
  • Neotame: Neurotoxic, Immunotoxic, Excitotoxic
  • Sucralose: May impact insulin sensitivity and cause DNA damage

Although, stevia is the only artificial sweetener that the research does not link with a side effect. 

Benefits of Diet Soda

Diet soda contains no nutrients, hence providing no health benefits. But it has some comparative advantages over regular soda. Here is the list of advantages:

  • Unlike regular soda, it doesn’t contain any calories. So, people can drink diet soda in moderation.
  • Secondly, as the quantity of sugar is zero too, so for individuals with insulin-dependent diabetes, it doesn’t require an additional affront dosage.

Once in a while, people with diabetes can enjoy refreshing diet soda with proper diet and exercise.

Diet Soda and Health Risks

The intake of artificially sweetened (diet) and sugar-sweetened (regular) soda can lead to a higher risk of diabetes. 

Research suggests that daily diet soda consumption can lead to a 36% higher relative risk of metabolic syndrome and a 67% higher risk of type 2 diabetes than nonconsumption.

Another study claims that you cannot exclude diet soda as an independent diabetes risk factor. Therefore, switching to artificially sweetened diet beverages may not lessen your risk of diabetes. On the other hand, as per the study, sugar-sweetened drinks contribute to diabetes. 

It’s advisable for people with diabetes to make their delicious Diabetes-friendly soda. As mentioned above, stevia has no recorded side effects. Therefore, people consider it a safe alternative to sugar used in soda. Furthermore, instead of using store-bought, processed stevia, people can opt for the dried leaves from the stevia plant itself.

Research shows that stevia extract significantly reduced fasting glucose levels, random glucose levels, and glycosylated haemoglobin. Furthermore, it improved the insulin and liver glycogen levels in rats. Hence, stevia does not only have side effects, but it betters diabetic conditions. 

The water used to make soft drinks can also quickly be carbonated at home to create fizz.

Alternative Healthy Drinks for People with Diabetes 

While it is best to avoid excess consumption of salt, carbohydrates, and sugar, moderation in these components can help people enjoy their favourite foods and beverages. Moderation does not imply that one needs to eliminate particular foods from their diet. Instead, people can occasionally consume these foods in small quantities. Try out these alternative healthy drink recipes mentioned below:

Sour Mango Sharbat

  • Servings: 2
  • Preparation Time: 15 mins


  • Semi-raw mango: ½ a semi-raw mango
  • Mint leaves: 1 sprig
  • Cold Water: 450ml
  • Dried and crushed stevia leaves to taste
  • Pink salt to taste

Method of Preparation

  • Peel and cut one side of your mango.
  • Blitz it in the grinder to a pulp.
  • Add equal amounts of the pulp into two glass tumblers.
  • Add a pinch of salt and stevia to taste.
  • Wash and tear mint leaves to release juices and add them to the tumblers.
  • Add cold water and mix.
  • Serve fresh or make in a big batch to store for a week in the fridge.

Moderation prevents depression caused by the feeling of being restricted about necessities such as food. Moreover, discipline in the timing of each meal can help manage diabetes. Research says that having meals timely can help maintain blood glucose levels. Similarly, eating an early dinner boosts lipid metabolism and improves blood glucose levels. If you want to add some refreshing sweet beverages to your your diet, you can connect to the HealthifyPro nutritionists, and gain insight on this.

Other Delicious Alternatives

People with diabetes should avoid artificial sweet drinks, and they can opt for tender coconut water that provides hydration and various antioxidants. Also, one should avoid adding extra sugar to homemade beverages.

Traditional Indian cold drinks such as buttermilk (chaas) and sharbat are also deemed safe for consumption in diabetics. Therefore, one can opt for a cold glass of buttermilk when they are craving something cold like a soft drink. However, one should remember that they ought not to add more salt than recommended salt intake because even that is harmful to people with diabetes. 

Another option for a cold and refreshing drink is to make sharbat. Sharbat, just like homemade soda, uses water as a solvent. Instead of sugar, you can also use stevia leaves or fresh fruits as natural sweeteners.


Everyone knows that diabetes is a chronic condition that affects how food converts into energy in bodies. When the body breaks down food to glucose, insulin lets it into the body’s cells. However, in diabetes, the body is either producing low quantities of insulin or does not use insulin optimally. Hence, it is crucial to control the blood glucose levels in the body.

There are tremendous benefits from eating healthy and exercising. A healthy diet and regular movement help regulate blood glucose levels. Research says that dietary components tend to impact our blood glucose levels significantly. For example, the body derives sugar or glucose from carbohydrates present in food. That is why it is advisable to avoid excess consumption of carbohydrates when diagnosed with diabetes.

Both the choice of food and its quantities are relevant in this case. The amount of carbohydrates in foods and beverages is significant. In addition, one of the prevalent beverages among all age groups and equally damaging to health is carbonated beverages. Therefore, one should opt for healthier drink options like buttermilk, tender coconut water etc. 

With all these alternatives and healthy moderations, people with diabetes can indulge in their drinks of choice while also ensuring good health.

  1. I have diabetes-2. But I love to drink pop. Sadly, I have read conflicting reports about whether diet pop is better to drink or the so called zero-sugar is better. Any help?

    • I have been a type 1 diabetic for 73+ years. I rely on sugar-free pop to drink daily. I know of little to no problems associated with drinking zero sugar Coke. I just limit the number that I have each day to 1.

      • Sugar-free or diet soda, pop or similar drinks have artificial sweeteners. Recent studies suggest that artificial sweeteners long term, daily or frequent, use may increase the risk of heart issues, insulin resistance or glucose intolerance and also affect digestive health. So for a healthier alternative, try pure 100% stevia. Water, lemon water, and green or herbal tea are way better than pop or coke.
