Although the FDA does not approve the consumption of raw stevia, pure extracts are considered safe. The FDA approved only highly purified steviol glycosides from stevia leaves as they are considered safe to use.

While some types of sweeteners in this category are considered low in calories (e.g.
steviol glycosides are not absorbed in the upper gastrointestinal tract and therefore do not provide calories or affect blood glucose levels. When they reach the colon, intestinal microbes break apart glucose molecules and use them as an energy source. The remaining vertebral column of steviol is then absorbed through the portal vein, metabolized in the liver, and excreted in the urine. 1.2 YES.
The metabolism of stevia is the same in healthy children as in healthy adults. 11 Therefore, the FDA and JECFA have concluded that high-purity stevia sweeteners are safe for children consume them within the recommended daily dosage. Stevia sweeteners can add sweetness to a child's food and drinks without contributing to the calories consumed or the intake of added sugars. Stevia sweeteners are not cariogenic, so they do not increase the risk of dental caries5. In order to reduce the consumption of added sugars in recent decades, the number of food products and beverages containing low calorie sweeteners has increased.
Although observational research among children and adults has demonstrated an increase in the percentage of people who report daily consumption of products containing low calorie sweeteners,12 the current intake of low calorie sweeteners is considered to be within acceptable levels, 8,70 A model study estimated the intake of sweeteners with stevia in children with type 1 diabetes, who may be at greater risk of exceeding ADI due to the need to reduce the consumption of added sugars, 13 The researchers concluded that there is little chance that children with type 1 diabetes will: exceed the ADI for stevia sweeteners. Foods and beverages made with stevia sweeteners are often recommended to people with diabetes as an alternative to sugar-sweetened foods and drinks and as a way to help these people satisfy their desire for sweet taste and, at the same time, control their intake of carbohydrates. Extensive research shows that stevia sweeteners do not raise blood glucose levels or otherwise affect blood glucose control in humans. 19-23 Recent consensus statements from experts in nutrition, medicine, physical activity and public health cite the neutral effects of low calorie sweeteners on hemoglobin A1C, postprandial glucose and fasting insulin levels and conclude that the use of low calorie sweeteners for personal diabetes care may contribute to better glycemic control.
Making a single change, such as replacing low-calorie sweetened options with high-calorie, sugar-containing products, is just one approach. Behavioral and lifestyle practices, such as eating healthy, exercising regularly, getting enough sleep, and maintaining social support networks, are important factors in achieving weight loss and maintenance goals. While research on the gut microbiome is still in its infancy, it's been recognized that the microbes that live in our intestinal tract can contribute significantly to our health. The gut microbiota is an integral part of steviol glycoside metabolism, a process that research has demonstrated has a limited effect on the composition of the human gut microbiome itself, 61 as observed in an in vitro study in 2003, 62 However, no randomized clinical trials have yet been conducted in humans and, to date, there is no evidence that stevia sweeteners have a significant impact on the composition or function of the gut microbiome. Adopting an active and healthy lifestyle that fits personal goals and priorities is vital to supporting personal well-being.
Choosing foods and beverages sweetened with low-calorie or no-calorie sweeteners, such as stevia, is one way to reduce the consumption of added sugars and keep calories under control, important components for maintaining health and reducing the risk of lifestyle-related diseases. New research on stevia, a plant-based sweetener, indicates that the sugar substitute may have negative implications for gut health. You can find stevia powder or liquid in grocery stores and health food stores in the aisles of bakery products or health foods. The antioxidant properties of stevia extracts depend on the methods of processing the extract, including the drying and extraction steps.
If you find whole stevia leaves or raw stevia extracts at your local health food store, don't buy them. According to the results of a previous study, stevia extract reduced the fertility of rats by up to 21% compared to the control group of rats. Whole stevia leaves and raw stevia leaf extracts are not approved food additives because there isn't enough toxicological information available, according to the FDA. Six leaf extracts and three stevia flower extracts obtained with different solvents showed good antibacterial activity against all the microorganisms tested.
Stevia preparations are used in many ways, such as fresh and dried stevia leaves, powdered stevia leaves, liquid extracts and concentrates. Pure sweet glucosides and raw stevia extracts with 50% glycosides are used actively in the food market. The researchers plan to study stevia more closely and use their findings to shape guidelines for stevia consumption. It may also explain why participants in another human experiment did not consume additional food to compensate for the lack of calories when given stevia extract, unlike participants who consumed sucrose (Anton et al.
Products that are considered safe contain words on their ingredient list, such as stevia extract or stevia rebaudiana. Unfortunately, many commercial stevia products are highly purified stevia extracts and aren't always as healthy as some of their “natural” labels would have you believe. Many studies have suggested the benefits of stevia extract over sugar and artificial sweeteners, but it's not yet a very popular sugar substitute. In tests, pure stevia extract has been found to have no effect on blood glucose levels (and may even improve the body's ability to metabolize glucose).
