2006-03-04T12:06:00.000-08:00

Stevia is completely natural and doesn’t affect blood sugar levels like sugar does, or pollute our bodies like artificial sweeteners do. Plus, you don’t need to use much, since it is very concentrated. You most likely won’t find Stevia on your grocer’s shelves yet, but it is available at whole food and natural food stores everywhere. It generally comes in liquid or powdered form. For those concerned with sugar intake, Stevia is a wonderful alternative.

Stevia: Inexpense and non-patentable

2006-02-26T10:39:00.000-08:00

"The principal importance of Ka he'e (stevia) is due to the possibility of
substituting it for saccharine. It presents these great advantages over
saccharine:

1. It is not toxic but, on the contrary, it is healthful, as shown by
long experience and according to the studies of Dr. Rebaudi.
2. It is a sweetening agent of great power.
3. It can be employed directly in its natural state, (pulverized leaves).
4. It is much cheaper than saccharine."

Unfortunately, this last point may have been the undoing of stevia.
Noncaloric sweeteners are a big business in the U.S., as are caloric
sweeteners like sugar and the sugar-alcohols, sorbitol, mannitol and
xylitol. It is small wonder that the powerful sweetener interests here, do
not want the natural, inexpensive, and non-patentable stevia approved in
the U.S.

Are the sugar moieties of stevioside safe for diabetics?

2006-02-11T16:37:00.000-08:00

Stevioside, the main sweet component of Stevia, is about 300 times sweeter than table sugar. Therefore, only small amounts need to be used for sweetening purposes. It is not taken up by the intestines and is not metabolised by enzymes of the gastro-intestinal tract as the sugar bonds in stevioside are beta-glucosidic bonds. However, it is degraded to steviol and sugar moieties by bacteria of the human colon. To substitute for the total amount of added sugar in the food (± 131 g per person per day in Belgium) less than 400 mg stevioside are required per day. This means that in the colon only about 240 mg of glucose is released from the 400 mg stevioside. It can be estimated that about 1/3 of this glucose is metabolised by the bacteria of the colon, 1/3 is excreted and about 1/3 is taken up (± 80 mg) which of course is a neglectible amount of glucose.

Stevia and Body Building

2006-02-11T16:32:00.000-08:00

Due to its almost zero calorie nature, Stevia is extremely useful to bodybuilders or obese persons that are attempting to lose body fat. Because it is sweet, it reduces cravings for sugary foods. Stevia essentially fools the body into a state of satiation. This will result in less food being craved [and thus consumed], and reduce caloric intake. Stevia will help with the reduction of cravings, and the suppression of the appetite, without having to resort to products containing stimulants. Extracted from here

Stevia and Agriculture and Agri-Food Canada

2006-02-11T16:29:00.000-08:00

Agriculture and Agri-Food Canada has a large research effort aimed at developing an agricultural production system for stevia and, through breeding, to optimize its sensory characteristics. Stevia is a plant that produces a variety of high-potency low-calorie sweeteners in its' leaf tissue. Stevia sweeteners are in used in food products a number of countries including Japan, Brazil and China. Here in North America, the movement of society towards more natural foods has created a great deal of public interest in stevia. Complete article

Stevia rebaudiana Bertoni is one of 154 members of the genus Stevia. It is a member of the Compositae family and as such is related to sunflower, marigolds etc. Stevia has an alternate leaf arrangement and herbacious growth habit with flowers arranged in indeterminate heads. The flowers are small and white with a pale purple throat. The pollen can be highly allergenic. Stevia is self-incompatible and probably insect pollinated, the seeds are small, have very little endosperm and are dispersed in the wind via a hairy pappus.

Common Names used for Stevia

2006-01-22T11:40:00.000-08:00

Stevia, sweet leaf of Paraguay, caa-he-éé, kaa jheéé, ca-a-jhei, ca-a-yupi, azucacaa, eira-caa, capim doce, erva doce, sweet-herb, honey yerba, honeyleaf, yaa waan, candy leaf

Stevia Properties

2006-01-22T11:33:00.000-08:00

The dried leaf of Stevia was described as having sweet properties as early as 1899. It contains Stevisoid, a natural sweetener, which is 300 times as sweet as sugar, yet is not absorbed by the body and contains practically no calories. These properties make it useful in weight loss programs. Despite Stevia's sweetness, it does not produce tooth cavities. This may be due to its high fluoride or other high mineral content. It is frequently used by Rainforest Indians to sweeten foods and herbal teas. They also speak of the wonders of Stevia to treat diabetes, hypertension, and infections. It has been frequently reported that Stevia exhibits a hypoglycemic (lowers blood sugar) action. In one double blind study of 25 hospitalized patients, mean blood sugar dropped 35.2% six to eight hours after ingestion of Stevia. Other research reports suggest that it has hypotensive (lowers blood pressure) activity. One study found that a single oral dose of aqueous extract resulted in a decrease in systolic blood pressure of 9.5 %. Another study found that the use of Stevia for 30 days resulted in a decrease of both systolic and diastolic pressures. Stevia may also be effective against Candida albicans (yeast infection).

Stevia and Calories

2006-01-15T10:28:00.000-08:00

Because the human body does not metabolize the sweet glycosides - they pass right through the normal elimination channels - the body obtains no calories from stevia; therefore it is safe for diabetics and hypoglycemics in its pure, unadulterated form.

What makes Stevia sweet

2006-01-07T09:45:00.000-08:00

The sweet compounds found in stevia leaves are diterpene glycosides (steviol glycosides) and are synthesized, at least in the initial stages, using much the same pathway as gibberellic acid, an important plant hormone. The steviol glycoside and gibberellin pathways diverge at kaurene. In stevia, laurene is converted to steviol, the "backbone" of the sweet glycosides, then glucosylated or rhaminosylated to form the principle sweeteners. The precursor compounds are synthesized in the chloroplast, then from there are transported to the endoplasmic reticulum, Golgi apparatus and then vacuolated.

The purpose of these compounds in the stevia plant is not yet clear, but their high concentration in the leaf and the conservation of the pathway within the species would indicate that, at some point in evoluntionary time, their presence conferred significant advantage upon those individuals that possessed them. Some researchers feel that they act to repel certain insects and others speculate that it is an elaborate means of controlling levels of gibberellic acid.

The four major steviol glycosides are:
stevioside
rebaudioside A
rebaudioside C
dulcoside A

Two other glycosides that may be present in plant tissue are rebaudioside D and E; rebaudioside B has been detected but is probably an artifact formed during isolation. The normal proportions (w/w) of the four major glycosides are: stevioside 5-10%, rebaudioside A 2-4%, rebaudioside C 1-2% and dulcoside A 0.5-1%. They range in sweetness from 40 to 250 times sweeter than sugar. A number of stevia genotypes with anomalous glycoside proportions have been reported in the Korean and Japanese scientific and patent literature. It has long been known that rebaudioside A has the best sensory properties (most sweet, least bitter) of the four major steviol glycosides. Steviol glycosides are heat and pH stable, non-fermentable and do not darken upon cooking and therefore have a wide range of applications in food products.

Stevia

2006-01-07T09:25:00.000-08:00

Stevia, as it is commonly known, is native to valley of the Rio Monday in North Eastern Paraguay and is found on the edges of marshland on acid infertile sand or muck soils. The conquistadors had reported stevia to the Spanish during the 16th century but it remained in obscurity until it was again brought to the attention of Europeans in 1888 by M.S. Bertoni. Prior to any European discovery, it had had long to been known to the indigenous Guarani peoples native to that region. The Guarani called it caá-êhê, meaning sweet herb and used it to sweeten bitter drinks such as mate.

Where did Stevia come from?

2005-12-16T08:54:00.000-08:00

A sweet plant was discussed by Charles Darwin in conversations at the Royal Astromonical Society circa 1853.

Apparently on one of Darwin's last travels in South America, he found a sweet tasting herbacious plant in the Guarani valley which is on the border of Brazil and Paraguay.

Circa 1890 Moises Bertoni following Darwin's path in search of this sweet plant. Stevia got its name when Moises was asking where the plant was. They responsed by saying 'esta via', meaning over there. Hence the name as we know it 'Stevia'.

Moises' son Antonio from 1909 to 1929 identified and catalogued 318 species of the Stevia plant.
