Stevia is a sugar substitute that contains very few calories. There is growing interest in its use to help people with diabetes manage their blood sugar levels.
Stevia is a natural sweetener that comes from a shrub that is native to North and South America. It is an ingredient in many brands of sweetener, including SweetLeaf, Truvia, and Pure Via.
Although they are sweet, steviol glycosides can leave a bitter aftertaste, so most stevia products contain other ingredients to counteract this.
As a sweetener, stevia has grown in popularity, especially among people with diabetes. In this article, we look at the benefits of stevia for people with diabetes and if there are any risks when consuming this sweetener.
In a joint statement, the American Heart Association (AHA) and the American Diabetes Association (ADA) said that stevia and similar sweeteners can be beneficial for people with diabetes if they use them appropriately and do not compensate by eating extra calories at later meals.
The research found that blood glucose levels started to reduce 60–120 minutes after eating the jelly, even before the secretion of insulin.
Scientific studies we highlight in this article suggest that stevia may offer the following benefits for people with diabetes:
- possible antioxidant properties to fight disease
- blood sugar control, both when fasting and after meals
- improved satiety and reduced hunger
- less desire to eat extra calories later in the day
- protection against liver and kidney damage
- reduced triglyceride and cholesterol levels
Another benefit of stevia is its versatility. It is suitable for hot and cold beverages, and people can sprinkle it over oatmeal or fruit.
Stevia may also be suitable for baking, depending on the particular sweetener product and the recipe. However, it does not caramelize and is not a substitute for sugar in all types of cooking and baking.
Stevia extracts are usually safe for most people in moderate amounts.
In the United States, the Food and Drug Administration (FDA) categorize steviol glycosides as “
Steviol glycosides are often present in sugar-free drinks, jams, and dairy products.
Several studies have investigated the effects of stevia on blood sugar levels.
The researchers concluded that stevia is safe for people with diabetes to use as a substitute for sugar and other sweeteners.
A 2013 study in rats reported that using whole stevia leaf powder as a dietary supplement led to lower blood sugar levels. The results also suggested that stevia could reduce liver and kidney damage in the animals.
Stevia may also reduce hunger and improve satiety in people.
The sucrose preload had 493 calories, while both the stevia and aspartame preloads only contained 290 calories. Despite this, all three groups of participants reported similar hunger and satiety levels.
The people who ate the stevia preloads had significantly lower blood glucose levels after meals when the researchers compared them with the sucrose group. They also had lower insulin levels than those in both the aspartame and sucrose groups.
However, a more recent
It is also important to note that most of the research uses dried stevia leaf rather than stevia extracts.
Stevia extracts typically contain other ingredients, some of which may affect blood sugar levels. However, stevia leaf does not have GRAS status with the FDA, who do not allow manufacturers to use it as a sweetener.
Due to the focus on stevia for people with diabetes, many people wonder if it can treat or cure the condition.
There is currently no cure for diabetes, but people can manage the condition with medications and lifestyle changes. Stevia can help to support these lifestyle adaptions.
Using stevia in place of sugar in sweetened foods and drinks may help people with diabetes stabilize their blood glucose levels.
This replacement for sugar may also reduce the number of calories that a person consumes, which is likely to aid weight loss. Excess weight is a risk factor for type 2 diabetes and its complications, which include heart and kidney problems.
Safety studies on stevia
Some stevia products contain additives that may cause side effects. For example, sugar alcohols may cause the following symptoms in some individuals:
- nausea and vomiting
- stomach pain and cramping
- other digestive issues
However, sugar alcohols are otherwise safe for people with diabetes. According to the ADA, sugar alcohols contain fewer calories than sugar and do not affect blood glucose levels as much as other carbohydrates.
People with diabetes should check that their chosen stevia product does not contain other sweeteners that might increase blood glucose levels.
Other artificial sweeteners may help people with diabetes manage any cravings for sweet foods and beverages.
According to the ADA, the FDA have approved the following artificial sweeteners:
- acesulfame potassium (Sunnet, Sweet One)
- aspartame (NutraSweet)
- saccharin (Sweet’N Low, Sugar Twin)
- sucralose (Splenda)
Some of these sweeteners are available for purchase online, including Sweet’N Low and Splenda.
The body does not break down these sweeteners with the exception of aspartame. Instead, they pass through the digestive system and leave the body in the urine and stool. As with stevia, these sweeteners do not provide extra calories.
Sugar alcohols also increase sweetness without affecting blood sugar levels. The sugar alcohols that manufacturers commonly add to foods and beverages are:
However, many foods with artificial sweeteners as an ingredient still contain calories and carbohydrates. Sometimes, these foods can have almost as many carbohydrates as the sugar-rich versions.
For this reason, people should check nutrition labels carefully before selecting products to eat or drink.
Stevia is a sugar substitute that has almost no calories. Stevia products contain a highly purified extract from the stevia plant that the FDA consider to be generally safe.
Some scientific evidence suggests that stevia may help people reduce their risk of diabetes or help those with the condition manage their blood sugar levels.
However, research is often inconclusive, and other substances often accompany stevia extract in a consumer product due to stevia’s naturally bitter aftertaste.
Stevia alone is unlikely to affect a person’s blood sugar control significantly, but it could be beneficial alongside other treatments and lifestyle changes.
When choosing a stevia product, it is always essential to check the label for other ingredients that may affect blood sugar levels. Anyone who is unsure should seek advice from a doctor or dietician or contact the manufacturer of the sweetener.
