Stevia bio antioxydant naturel puissant

Stevia rebaudiana (Bertoni) is a South American plant native to Paraguay that traditionally has
been used to sweeten beverages and make tea. The word “stevia” refers to the entire plant and its
components, only some of which are sweet. The sweet tasting components of the stevia plant are
called steviol glycosides. Steviol glycosides can be isolated and purified from the leaves of the stevia plant and
are now added to some foods, beverages and tabletop sweeteners in the U.S. and elsewhere. The process of
isolating the sweet tasting, steviol glycosides is similar to “steeping” tea leaves.
While the word “stevia” actually refers to the entire plant, for the purposes of this web site, the term “stevia sweeteners”
will be used to refer to steviol glycosides which are the sweet components isolated and purified from stevia leaves. For an

Safety of Stevia Sweeteners/Steviol Glycosides
Studies clearly support the safety of stevia sweeteners. Further, clinical studies show that steviol
glycosides, meeting purity criteria established by the Joint FAO/WHO Expert Committee on Food
Additives (JECFA), have no effect on either blood pressure or blood glucose response, indicating
stevia sweeteners are safe for use by individuals with diabetes.
Recent studies, including human studies on safety, metabolism and intake, support the safety of
stevia sweeteners. JECFA has conducted a thorough scientific review of the existing scientific data on
steviol glycosides and concluded that they are safe for use in food and beverages. Based on the wealth
of published research, independent scientific experts in both the U.S. and globally have concluded
that stevia sweeteners are safe for people of all ages and populations and an Acceptable Daily Intake
(ADI) of four mg/kg body weight (expressed as steviol) has been established. The estimated intake
of steviol glycosides even among the highest consumers does not exceed the ADI. Food and Chemical
Toxicology published a special supplement on the topic of stevia sweetener safety in May 2008.
Metabolism
Based on studies conducted in the past several years, the Joint FAO/WHO Expert Committee
on Food Additives (JECFA) has concluded that stevia sweeteners are metabolized by a common
pathway. This begins in the gut where the steviol glycosides are broken down to steviol. Steviol
is excreted in the urine as steviol glucuronide. The metabolized components of steviol glycosides
essentially leave the body and there is no accumulation.
Regulatory Status
In December 2008, in response to Generally Recognized As Safe (GRAS) notifications submitted to the US Food
and Drug Administration (FDA), the FDA stated it has no questions regarding the conclusion of expert
panels that rebaudioside A is GRAS for use as a general purpose sweetener in foods and beverages, excluding
meat and poultry. Rebaudioside A is a stevia sweetener isolated and purified from the leaves of the stevia plant.
In June 2009, FDA stated it has no questions regarding the conclusion of an expert panel on the GRAS status of
another steviol glycoside extract with high rebaudioside A content for use as a tabletop sweetener. Similar GRAS
notifications are before FDA for other steviol glycoside extracts isolated and purified from Stevia rebaudiana.
In Europe, stevia is approved as a dietary supplement but not yet for use as a sweetener. The
European Food Safety Authority (EFSA) is currently conducting a safety assessment. In Canada,
stevia is sold as a natural health product. Stevia and steviol glycosides have a long history of use in
several countries, including Japan and Paraguay. Stevia sweeteners are approved for use in many
other countries, including Korea, Mexico, Taiwan, China, Russia, Australia, Argentina, New
Zealand, Colombia, Peru, Uruguay, Brazil and Malaysia.

What are some common and trade names for stevia sweeteners?
Enliten®
PureVia™ Reb A Rebiana Stevioside Sun Crystals® Stevie
What is rebaudioside A?
Rebaudioside A is a sweet tasting steviol glycoside purified from the leaves of the stevia plant.
What is stevia?
Stevia is a plant of the Chrysanthemum family, the leaves of which have been used as a sweetener
in South America for hundreds of years. Extracts from the stevia leaf have been available as dietary
supplements in the U.S. since the mid-1990’s and many contain a mixture of both sweet and non-
sweet components of the stevia leaf.
What is the difference between stevia, rebaudioside A and steviol glycosides?
The term stevia typically refers to a crude preparation (powder or liquid) of dried stevia leaves. It
may contain a mixture of many substances, only some of which are sweet. Steviol glycosides can
be isolated and purified from the leaves of the stevia plant and can be used to sweeten foods and
beverages and used as tabletop sweeteners. Rebaudioside A is one of the steviol glycosides purified
from the leaf of the stevia plant. Other steviol glycosides include stevioside, rebaudiosides B, C, D, F,
steviolbioside, rubusoside, and dulcoside A.
Natural
What is natural?
Although there is no clear definition of “natural,” some consumers prefer ingredients derived from natural
sources that undergo minimal processing and that are not altered during production. New products with
natural claims such as stevia sweeteners give consumers more products from which to choose.

Are foods labeled “natural” better or more healthful?
Not necessarily. Since there is no clear definition or labeling requirement, the primary difference
between foods labeled “natural” and foods that do not bear this claim is preference.
Foods and Beverages with Stevia Sweeteners
In what types of foods are stevia sweeteners used?
Stevia sweeteners can be used in beverages and foods such as desserts, sauces, yogurt, pickled foods,
breads and confections.
Weight Control and a Healthful Lifestyle
How many calories do stevia sweeteners contain?
Steviol glycosides have zero calories. Stevia-based tabletop sweeteners can have zero or minimal calories
per serving, depending upon the other food ingredients with which they are combined. For example, some stevia
sweeteners may be mixed with sugar as a bulking agent and these stevia sweeteners will contain some calories.
How are stevia sweeteners helpful in weight control?
With zero calories, stevia sweeteners can help reduce or replace calories in foods and beverages and offer low and
no calorie alternatives for people looking to lose and control weight. Consuming beverages and foods with
stevia sweeteners as part of a healthful diet and lifestyle, including regular physical activity, can assist with weight
control and weight loss.
Metabolism
How are stevia sweeteners metabolized?
Based on studies conducted in the past several years, the Joint FAO/WHO Expert Committee
on Food Additives (JECFA) has concluded that stevia sweeteners are metabolized by a common
pathway. This begins in the gut where the steviol glycosides are broken down to steviol. Steviol is
excreted in the urine as steviol glucuronide and the metabolized components of steviol glycosides
essentially leave the body and there is no accumulation.
Safety and Dietary Intake
What is Generally Recognized As Safe (GRAS) status?
In order for a new food or beverage ingredient to enter the U.S. food supply, the ingredient must either be a
Food and Drug Administration (FDA) approved food additive or GRAS. The quality and quantity of scientific
evidence required for a substance to achieve GRAS status are the same as for FDA food additive approval.
For GRAS, however, there is a general knowledge requirement and acceptance of that knowledge by
qualified scientists. Publication in a peer reviewed scientific journal is the mechanism normally used to
establish that the necessary scientific information is generally available.

How has the safety of stevia sweeteners been
established?
Studies of stevia sweeteners clearly support the safety of these ingredients. Further, clinical studies show that
stevia sweeteners meeting purity criteria established by JECFA have no effect on either blood pressure or blood
glucose response, indicating stevia sweeteners are safe for use by persons with diabetes. In December 2008, the
US Food and Drug Administration (FDA) stated it has no questions regarding the conclusion of expert panels
that rebaudioside A is Generally Recognized As Safe (GRAS) for use as a general purpose sweetener. To date,
FDA has stated that it has no questions in response to three separate stevia sweetener GRAS notifications.
What is the Acceptable Daily Intake (ADI)?
The Joint FAO/WHO Expert Committee on Food Additives (JECFA) defines Acceptable Daily
Intake (ADI) as “An estimate of the amount of a substance in food or drinking water, expressed on
a body-weight basis, that can be ingested daily over a lifetime without appreciable risk (standard
human = 60 kg). The ADI is listed in units of mg [milligram] per kg [kilogram] of body weight.”
Consuming more than the ADI does not mean an effect will occur because the ADI includes a wide
margin of safety above what is deemed the “No Observed Effect Level.” JECFA has assigned an ADI
of four mg/kg bw for steviol glycosides, expressed as steviol.
How are stevia sweeteners useful for people with diabetes? Research has shown that stevia
sweeteners do not affect blood glucose levels or interfere with insulin. With zero calories, stevia
sweeteners offer people with diabetes greater variety and flexibility in budgeting total calorie intake
and assisting with weight management.
Are there any known allergies to stevia sweeteners? There are no known allergies to stevia sweeteners.
Cooking and Baking
Can stevia sweeteners be used in cooking and baking? Stevia sweeteners provide an excellent
alternative when sweetening foods such as cereal, yogurt and fruit. Some recipes allow for cooking
and baking with these sweeteners, however appropriate usage levels vary according to the stevia
sweetener that is used. For best results, follow the directions outlined by the manufacturer.

Stevia rebaudiana is a South American plant, native to Paraguay that has long been used to
sweeten beverages and make tea. The term stevia typically refers to sweeteners made from a crude
preparation (powder or liquid) of dried stevia leaves. These preparations may contain a mixture of
many substances, only some of which are sweet. While the word “stevia” refers to the entire plant,
only some of the components of the stevia leaf are sweet. These sweet components are called steviol
glycosides. Stevia is grown and harvested in many countries around the world, predominantly in
China and Brazil.
Stevia sweeteners are also ingredients in many products, such as ice cream, bread and soft drinks,
throughout Asia and South America. In the US, stevia sweeteners are primarily found in tabletop
products and reduced calorie beverages. Heightened regard for caloric consumption and increased
demand from consumers for a greater variety of low calorie products has provided an impetus to
incorporate stevia sweeteners into foods and beverages.

Steviol Glycosides
Steviol glycosides are found in the leaves of the stevia plant and each has a particular taste profile
and sweetness intensity. Steviol glycosides can be isolated from the leaves of the stevia plant. The
process of isolating the sweet tasting steviol glycosides from the leaves of the stevia plant is similar
to “steeping” tea leaves. Steviol glycosides are approved for use in countries such as Australia,
Brazil, China, Japan, Korea, New Zealand and Paraguay. In the U.S., steviol glycosides with high
rebaudioside content are Generally Recognized As Safe (GRAS) for use as a tabletop sweetener.
Rebaudioside A
Rebaudioside A is one of the many steviol glycosides in stevia leaves that provide sweetness. In the
US, rebaudioside A is Generally Recognized As Safe (GRAS) for use as a general purpose sweetener
and may be used in foods and beverages, excluding meat and poultry products. Rebaudioside A is
approximately 250 to 300 times sweeter than sucrose.
Components of stevia sweeteners contain zero calories, which mean these sweeteners may sweeten
food and beverages resulting in fewer calories. Further, research has shown that stevia sweeteners
do not contribute calories or carbohydrates to the diet and do
not affect blood glucose or insulin response, which allows people with
diabetes to consume a greater variety of foods and comply with a healthful
meal plan. Stevia sweeteners are an excellent alternative for use in foods
and beverages such as diet beverages.
The sweet components in stevia sweeteners are naturally occurring
which may further benefit consumers who prefer foods and beverages they
perceive as natural.
