1) Diabetes
Research has shown that stevia sweeteners do not contribute calories or carbohydrates to the diet. They have also demonstrated no effect on blood glucose or insulin response. This allows people with diabetes to eat a wider variety of foods and comply with a healthful meal plan.

There are many causes of overweight and obesity, such as physical inactivity and increased intake of energy-dense foods that are high in fat and added sugars.

The intake of added sugars has been shown to contribute an average of 16 percent of the total calories in the American diet. This has been linked to weight gainTrusted Source and reduced control of blood glucose levels.

Stevia contains no sugar and very few, if any, calories. It can be part of a well-balanced diet to help reduce energy intake without sacrificing taste.

3) Pancreatic cancer
Stevia contains many sterols and antioxidant compounds, including kaempferol.

Studies have found that kaempferol can reduce the risk of pancreatic cancer by 23 percentTrusted Source.

4) Blood pressure
Certain glycosides in stevia extract have been found to dilate blood vessels. They can also increase sodium excretion and urine output.

A 2003 study showed that stevia could potentially help lower blood pressure. The study suggested that the stevia plant might have cardiotonic actions. Cardiotonic actions normalize blood pressure and regulate the heartbeat.
