Debunking Myths About Stevia
As Americans are increasingly reducing their added sugar intake, the door has opened for sugar alternatives, like stevia, to sub in for sugar. With all the sweetness and none of the calories, stevia has quickly become a popular option used in processed goods and at home.
Learn more about what exactly stevia is as we debunk some of the biggest myths surrounding this sugar alternative.
What is stevia?
Stevia is a non-nutritive or zero-calorie alternative to sugar. The sweetener comes from the leaves of the Stevia r
ebaudiana plant, a shrub native to South America1. The indigenous population there has been using the leaf of the stevia plant for its sweetness for over 100 years.
The plant’s sweet taste can be anywhere from 180-400 times sweeter than table sugar. Plus it contains so few calories it’s considered “zero-calorie”, making it a popular sweetener used in soda, baked goods, canned fruits, dairy products, and more for those looking to cut back on sugar.
What is the difference between sugar and stevia?
While sugar gets a bad rap, it actually plays an important function in our body: providing us with the energy our cells need to survive. Sugar is a class of carbohydrate found naturally in many foods like fruit, vegetables, and other plants. There are three types of simple sugars: glucose, fructose, and galactose. These simple sugars are the building blocks that make up all types of carbohydrates.
The table sugar you pour into your coffee or add to your baked goods is called sucrose. It’s a compound that’s made up of two molecules—glucose and fructose—and, thus, will be broken down into these simple sugars once digested. Most table sugar you buy is made from sugar beets or sugar cane.
Stevia, on the other hand, is a non-nutritive sweetener because it offers zero nutritional value to the body. The stevia leaf extract is a compound that is not metabolized like sugar. Rather, it passes through the body and is primarily excreted in the urine, meaning it provides sweetness without the calories.
While this sugar alternative has some pretty sweet benefits compared to sugar, there are still myths that need busting on the role of stevia in your diet.
Myth 1: Stevia is an artificial sweetener
Stevia is a natural sweetener because it comes from the Stevia rebaudiana plant. Artificial sweeteners, such as aspartame and acesulfame K, are man-made or chemically modified in a lab.
Both stevia extract and artificial sweeteners are Generally Recognized as Safe (GRAS) by the U.S. Food and Drug Administration (FDA); however, whole leaf stevia is not GRAS approved and is still under review. This means any stevia you consume is an extract from the leaf as opposed to the whole leaf itself. This extraction process is where stevia often gets mislabeled as an artificial sweetener even though the sweetener itself is natural.
Myth 2: Stevia is bad for you
Stevia and other non-nutritive sugar alternatives have zero calories and zero nutritional value, but that doesn’t mean they have zero benefits. Non-nutritive sweeteners can support a healthy diet by helping you limit your sugar intake because consuming too much added sugar is linked to various health concerns. (Reminder: stevia and other non-nutritive sweeteners such as aspartame, saccharin, sucralose, cyclamate, and acesulfame K are not added sugars.)
When eaten in excess, sugar can be addictive; anyone embarking on a no added sugar diet knows how hard it can be to cut out added sugar. This is because sugar activates your brain’s reward center much like the addiction response of certain drugs. Scientists at the U.S. National Institute on Drug Abuse were among the first to show that sugar can change the way your brain is wired, much like cocaine or alcohol. The more sugar you eat, the more you need to satisfy your cravings. When you stop eating sugar your body goes into a state of withdrawal, similar to other addiction recovery responses.
As a result, non-nutritive sweeteners are often used to help limit the amount of added sugar in the diet while still providing sweetness. By replacing your sugar-sweetened beverage or food with a non-nutritive sugar alternative like stevia, you can reduce your added sugar intake without completely removing sweets from your diet. The American Heart Association encourages this as a potential strategy for reducing sugar-sweetened beverages and food items.
While researchers are still examining how the body processes all sugar alternatives, stevia has been shown to be a helpful tool for reducing or limiting your added sugar intake.
Myth 3: Stevia doesn’t help with weight loss
Sugar, particularly sugar-sweetened beverages, is associated with an unhealthy diet, increased calorie consumption, and obesity. By replacing added sugar with a zero-calorie sweetener like stevia, you could help reduce that calorie consumption to support your weight loss goals.
In one study comparing stevia, sugar, and water consumption, researchers found that drinking a stevia-sweetened beverage before a meal can help reduce your appetite and total energy intake more than both a sugar-sweetened beverage and water.
However, it’s key to keep in mind that stevia by itself is not a magic pill for weight loss. It’s not stevia that aids in weight loss, but rather the lack of added calories through sugar. It’s one piece of the puzzle to a healthier lifestyle.
It’s often the choices you make alongside your stevia consumption that result in weight gain or weight loss. Weight loss requires a lot of work outside of just swapping your soda with a stevia-sweetened beverage. A healthy lifestyle involves everything from healthy eating, to exercise, to sleep, and more.
Myth 4: Stevia impacts your digestive health
Some artificial sweeteners, like sucralose, aspartame, and saccharin, have been found to potentially disrupt the gut microbiota. In a study done on mice, this disruption resulted in impaired glucose tolerance, which is a major risk factor for several metabolic diseases. Another study on mice with eight weeks of exposure to aspartame also led to impaired glucose tolerance. Neither of these studies involved stevia.
However, research is divided on the topic of gut health and sweeteners. Another literature review and panel of experts found no conclusive evidence that low-calorie sweeteners like stevia impact human gut microbiota2, especially when you consider the low concentrations of stevia in your food and beverages.
Another study from Glasgow, UK that measured the effect of thirteen different food additives, sweeteners, and hygiene products found that stevia was one of the few that had no or minimal effect on the gut.
Although we need more research in this area, the evidence so far today suggests that stevia does not play any major positive or negative role in your digestive health.
Luckily, that’s what OLIPOP is here for instead! We've assembled a global team of leading human gut microbiome research pioneers to craft a soda focused on supporting your gut health with plant fiber, prebiotics, and botanicals.
Myth 5: Stevia is bad for diabetics because it affects blood sugar
Sugar-sweetened beverages spike your glucose and insulin levels as your body works hard to manage all this sugar running through your system. Whether sugar substitutes or sweeteners impact your body in the same way is up for debate.
In one study, participants had a higher blood glucose level after drinking maltodextrin, glucose, and sucrose beverages compared to both water and stevia9. Other studies have found opposite results with a larger increase in glucose levels after stevia consumption compared to sugar. One study reports a 22% higher incidence of diabetes among non-nutritive sweetener consumers; however, this study is observational and thus does not prove that non-nutritive sweeteners increase risk of developing diabetes.
Most studies show that stevia promotes a much lower glucose response than sugar. This suggests that any links between diabetes and non-nutritive sweeteners could be the result of reverse causality or confusion around cause and effect.
For example, an obese individual might be more likely to drink a non-nutritive sweetened beverage as part of a weight-loss solution. Obesity is a risk factor for diabetes, meaning that obesity may be the cause of diabetes, not the sweetener.
Given the research suggesting stevia’s much lower blood glucose levels compared to sugar, stevia-sweetened beverages are often recommended to people with diabetes as an alternative to high-sugar foods and drinks.
The 2021 American Diabetes Association Standards of Medical Care in Diabetes15 states that:
“For some people with diabetes who are accustomed to regularly consuming sugar-sweetened products, nonnutritive sweeteners (containing few or no calories) may be an acceptable substitute for nutritive sweeteners (those containing calories, such as sugar, honey, and agave syrup) when consumed in moderation. Use of nonnutritive sweeteners does not appear to have a significant effect on glycemic management, but they can reduce overall calorie and carbohydrate intake, as long as individuals are not compensating with additional calories from other food sources.”
Consuming stevia in moderation and in replacement of sugar could help support diabetes prevention and management. However, it is important to consult with your doctor about what solutions make the most sense for your situation.
Does OLIPOP use stevia?
Stevia extract is one of the sweeteners we use in OLIPOP. We’ve spent years formulating a unique sweetening blend that combines natural sugars from fruits, cassava syrup, and a high-quality, mild strain of stevia leaf extract for maximum enjoyment.
This is how we can make a delicious drink without adding artificial sweeteners or high fructose corn syrup. Instead, stevia offers a naturally sweet taste with none of the calories, which is how some of our flavors contain 95% less sugar than the leading soda brand. Plus we've loaded each bubbling flavor with digestive health supporting ingredients for better gut health along with a refreshing taste.
