Coke Zero is a popular no-calorie soft drink that contains artificial sweeteners instead of sugar. There has been a lot of debate about whether diet sodas like Coke Zero are healthy options. This article will examine the ingredients in Coke Zero and weigh the potential pros and cons of drinking it.
What is in Coke Zero?
The main ingredients in Coke Zero are:
- Carbonated water
- Caramel color
- Phosphoric acid
- Aspartame
- Potassium benzoate
- Natural flavors
- Potassium citrate
- Acesulfame potassium
Coke Zero gets its sweet taste from a blend of aspartame and acesulfame potassium. These are artificial sweeteners that provide the taste of sugar without the calories.
Coke Zero contains no sugar, calories, or carbohydrates. The caramel color and natural flavors provide the signature Coca-Cola taste.
Potential benefits of drinking Coke Zero
Here are some of the touted benefits of drinking Coke Zero:
Zero calories
One of the main benefits of Coke Zero is that it has zero calories and sugar. This makes it an appealing option for people watching their calorie and sugar intake.
Drinking calorie-free sodas like Coke Zero can help reduce overall daily calorie consumption, which may aid weight loss or maintenance.
Provides taste without calories
Coke Zero provides the fizzy, cola taste without any calories or sugar. The combination of artificial sweeteners mimics the taste of full-sugar Coke.
For people who enjoy sugary sodas, Coke Zero offers the experience of drinking a Coke without the calories and carbs. This gives it an advantage over plain water.
Doesn’t impact blood sugar
Since Coke Zero has no sugar or carbs, it does not raise blood sugar levels. This makes it a good soda option for people with diabetes who need to monitor their blood sugar.
Studies show that swapping out regular soda for diet sodas like Coke Zero may help control blood sugar spikes and manage diabetes.
May support dental health
The sugar in regular soda can damage tooth enamel and lead to cavities and tooth decay. Because Coke Zero has no sugar, it does not have this impact on dental health.
Drinking Coke Zero instead of regular soda may help reduce the risk of cavities. However, the acidity of all sodas can still erode tooth enamel over time.
Potential downsides of drinking Coke Zero
Despite the benefits, there are also some potential downsides to consider with Coke Zero:
Contains artificial sweeteners
Coke Zero contains the artificial sweeteners aspartame and acesulfame potassium instead of real sugar.
While the FDA has approved these for use, some people worry about the effects of excessive artificial sweetener consumption. There is still debate about whether they are truly safe in the long run.
Acidity can damage teeth
Like all sodas, Coke Zero is highly acidic due to the carbonation and phosphoric acid. This acidity can erode and damage tooth enamel over time and lead to dental issues.
Lack of nutrients
Soft drinks like Coke Zero provide no nutritional value. They do not contain vitamins, minerals, fiber, protein or other nutrients.
Drinking Coke Zero instead of beverages like milk or juice means missing out on important nutrients.
May trigger sweet cravings
Artificially sweetened sodas may still trigger cravings for actual sugar because the taste buds sense sweetness. This could lead to overeating sugary foods later on.
Some studies suggest that consuming artificial sweeteners may increase appetite and food intake at subsequent meals.
Safety of aspartame and acesulfame potassium
Given that Coke Zero contains artificial sweeteners, it’s understandable to have concerns about their safety. Here is an overview of what science says so far about aspartame and acesulfame potassium:
Aspartame
- FDA approved its use in 1981 after reviewing extensive testing data.
- Present in over 6,000 products worldwide.
- Well over 200 studies support its safety.
- No credible evidence linking it to serious side effects in humans at typical doses.
- Considered safe for consumption by regulatory agencies worldwide.
Acesulfame potassium
- Approved for use by the FDA in dry products in 1988 and sodas in 1998.
- Over 90 studies confirm its safety.
- Does not accumulate in the body and is rapidly eliminated unchanged.
- No evidence of carcinogenicity or other serious side effects.
- Acceptable daily intake is 15 mg/kg of body weight, much higher than amounts present in Coke Zero.
At this time, there is no solid evidence from human studies that typical consumption of aspartame and acesulfame potassium is harmful. However, more research is still needed on the long-term effects.
Effect on health conditions
There are also some considerations about how Coke Zero may impact certain health conditions.
Diabetes
Studies show Coke Zero may help blood sugar control in people with diabetes since it does not raise blood sugar levels. However, concerns remain about it triggering sweet cravings that could lead to overeating.
Bone health
Some research links increased diet soda consumption to lower bone mineral density and increased fracture risk. But findings have been mixed. More research is needed specifically on Coke Zero.
Kidney health
One study linked diet sodas to a higher risk of kidney decline and kidney disease. But other research shows no adverse impact. Overall, there is no strong evidence linking Coke Zero itself to kidney problems.
Pregnancy and fertility
While Coke Zero offers an appealing no-calorie option for pregnant women concerned about excess weight gain, there are mixed opinions about whether it is safe during pregnancy. There have not been sufficient studies to confirm its safety.
