Is Coke Zero Bad for You? 7 Top Reasons

Now we’ll learn about 7 crucial reasons why coke zero is bad for you. 

1. Diabetic Risk

Coke Zero, despite being sugar-free, may not necessarily be a healthier option for individuals seeking to reduce their risk of diabetes due to the sugar substitutes it contains.

A 14-year study involving 66,118 women observed a connection between consuming artificially sweetened beverages and an increased risk of developing type 2 diabetes. Similarly, another study involving 2,019 individuals found a link between sugar-sweetened and artificially sweetened diet beverages and type 2 diabetes, suggesting that switching to diet soda may not lower the risk of diabetes.

In contrast, an 8-year study involving 64,850 women found that consuming artificially sweetened beverages increased the risk of diabetes by 21%, although the risk associated with sugar-sweetened drinks was even higher at 43%.

Interestingly, conflicting results have been found in other studies. For example, a 14-year study of 1,685 middle-aged adults did not establish an association between diet soda consumption and an increased risk of prediabetes.

Due to the conflicting findings, there is currently no exact explanation of how artificially sweetened beverages increase the risk of diabetes. Further research is required to gain a better understanding of this relationship.

2. Gut Microbiome and Disease Risk

Diet sodas, including Coke Zero, have been associated with alterations in the gut microbiome. The gut microbiome plays a crucial role in overall health and digestion. Additionally, some studies suggest that the consumption of diet sodas may be linked to an increased risk of osteoporosis, heart disease, and kidney disease.

However, it’s important to note that these associations do not necessarily imply causation and further research is needed to establish the precise relationship between diet sodas and these health risks.

3. Lack of Nutritional Benefits

Health experts generally do not recommend drinking soda, including Coke Zero, regularly due to their lack of nutritional benefits. These beverages provide no essential nutrients and may contribute to excessive calorie consumption without offering any significant nutritional value.

4. Risk of Enamel and Tooth Erosion

The acidic pH level of Coke Zero, similar to other carbonated beverages, is linked to a heightened risk of enamel and tooth erosion.  Acidic drinks can weaken the protective layer of enamel on the teeth, making them more susceptible to damage and erosion over time. However, Coke Zero may have a slightly lower acidity than regular Coke and other acidic beverages.

5. Risk of Heart Disease

A study found a correlation between artificially sweetened beverages and an elevated risk of heart disease among women without a history of heart disease.

6. Risk of Kidney Disease

The high phosphorus content in sodas, including diet sodas, may contribute to kidney damage. Research indicates that individuals who consume more than seven glasses of diet soda per week may double their risk of kidney disease.

7. Potential Increase in Osteoporosis Risk


Research has shown that daily cola intake and diet beverages may be associated with lower bone mineral density. This suggests a potential increased risk of osteoporosis.

Is it OK to Drink Coke Zero Every Day?

Consuming moderate diet soda, such as one or two cans per day, is generally considered safe and unlikely to cause harm. The artificial sweeteners and other chemicals used in diet soda are typically considered safe for most individuals, with no credible evidence linking them to cancer.

Certain types of diet soda are even enriched with vitamins and minerals. However, it’s important to note that diet soda should not be considered a healthy beverage or a magical weight-loss solution.

While switching from regular soda to diet soda may help reduce calorie intake, it remains unclear whether this can effectively prevent obesity and associated health issues in the long run.

There are healthier, low-calorie alternatives available. Below we’ll learn about them.

8 Healthier Low-Calorie Alternatives to Coke Zero

There are several healthier, low-calorie alternatives to Coke Zero That you can consider:

  1. Water: Water is the ultimate zero-calorie beverage and the best choice for hydration. It does not contain any added sugars or artificial sweeteners.
  2. Sparkling Water: If you enjoy carbonated beverages, choose plain or flavored sparkling water without added sugars. You can add a squeeze of lemon or lime for extra flavor.
  3. Unsweetened Tea: Green tea, black tea, herbal tea, or iced tea without added sugars can be refreshing and provide various health benefits.
  4. Herbal Infusions: Infused water with fruits, herbs, or vegetables can provide a flavorful, low-calorie option. Examples include cucumber-infused water, lemon-mint water, or berry-infused water.
  5. Unsweetened Coffee: Black coffee or coffee with a small amount of low-fat milk or a sugar substitute can be a low-calorie alternative.
  6. Skim or Low-Fat Milk: Skim or low-fat milk can be a good choice if you prefer dairy. They provide essential nutrients like calcium and protein while lowering calories than whole milk.
  7. Coconut Water: Coconut water is a natural, electrolyte-rich beverage that can offer hydration and a subtle sweetness. Look for brands without added sugars.

Does Coke Zero Have Benefits?

There are no significant benefits of Coke Zero except two. Below I’m describing them. 

1. Calorie-Free

Coke Zero is a calorie-free beverage that does not contribute to calorie intake. This can benefit those monitoring their caloric information in weight management or calorie-controlled diets. Individuals can enjoy the Coca-Cola flavor without adding extra calories to their diet by choosing Coke Zero instead of regular Coke or other sugary drinks.

2. Zero Sugar

One of the main benefits of Coke Zero is that it contains zero sugar. Instead, it is sweetened with artificial sweeteners like aspartame and acesulfame potassium, which provide the signature Coca-Cola flavor without the sugar content.

This can be particularly appealing to individuals looking to reduce their sugar consumption for various reasons, including weight management, diabetes management, or overall health concerns related to excessive sugar intake.
