Think Again About Stevia

I really have used, a lot of stevia, in all forms. I stopped when I noticed my major lung problem stopped when I didn't have my daily diet drink that Coke came out with. So then I began to look up the side effect. I noticed I needed more calcium, had heart problems and made my asthma worse with attacks at night. I stopper and I'm getting so much better. If you have some of the cautions in this post stop till symptoms are gone. Take more and see if it returns. I won't do that I had sever renal failure.

         Stevia is perhaps unique among food ingredients because it's most valued for what it doesn't do. It doesn't add calories. Unlike other sugar substitutes, stevia is derived from a plant.
The stevia plant is part of the Asteraceae family, related to the daisy and ragweed. Several stevia species called "candyleaf" are native to New Mexico, Arizona and Texas.

But the prized species, Stevia rebaudiana (Bertoni), grows in Paraguay and Brazil, where people have used leaves from the stevia bush to sweeten food for hundreds of years. In traditional medicine in these regions, stevia also served as a treatment for burns, colic, stomach problems and sometimes as a contraceptive.


Today, stevia is part of the sugar substitute market.
The U.S. Department of Agriculture estimates Americans added more sugar to their diet every year since the 1970s until 2000. When Americans dropped the added sugar, they turned to sugar like extracts. The sugar substitute market was estimated to be worth $10.5 billion in 2012, according an analysis by Markets and Markets research firm.

And the market may be growing. Just 18 percent of U.S. adults used low- or no-calorie sweeteners in 2000. Now, 24 percent of adults and 12 percent of children use the sugar substitutes, according to a 2012 review in the American Journal of Clinical Nutrition. [9 Snack Foods: Healthy or Not?]
Does stevia work?
Stevia has no calories, but it is 200 times sweeter than sugar in the same concentration. Other studies suggest stevia might have extra health benefits.
"Available research is promising for the use of stevia in hypertension," said Catherine Ulbricht, senior pharmacist at Massachusetts General Hospital in Boston and co-founder of Natural Standard Research Collaboration, which reviews evidence on herbs and supplements. Ulbricht said Natural Standard gave stevia a "grade B for efficacy" in lowering blood pressure. Other studies suggest stevia could benefit people with Type 2 diabetes, but Ulbricht says more research is needed.
A no-calorie source of sweetness is an obvious diet solution in theory. But a few studies show that replacing sugar with artificial or low-calorie sweeteners may not ultimately lead to weight loss in real life.
A 2004 study in rats found low-calorie sweeteners led the animals to overeat, possibly because of a mismatch between the perceived sweetness and the expected calories from sugar, according to the paper in the International Journal of Obesity and Related Metabolic Disorders.


The author of that study later argued that people who use artificial sweeteners may suffer health problems associated with excess sugar, including metabolic syndrome, which can be a precursor to diabetes.
"A number of studies suggest people who regularly consume ASB [artificially sweetened beverages] are at increased risk compared with those that do not consume ASB," Dr. Susan E. Swithers said in a 2013 opinion letter in the journal Trends in Endocrinology and Metabolism.
Yet there is also evidence that stevia does nothing to change eating habits or hurt metabolism in the short term. A 2010 study in the journal Appetite tested several artificial sweeteners against sugar and each other in 19 lean people and 12 obese people.
The study found people did not overeat after consuming a meal made with stevia instead of sugar. Their blood sugar was lower after a meal made with stevia than after eating a meal with sugar, and eating food with stevia resulted in lower insulin levels than eating either sucrose and aspartame.

Is stevia safe?

Can cause cramp too

The question of whether stevia is safe to consume largely depends on what someone means by "stevia." The U.S. Food and Drug Administration has not approved stevia leaves or "crude stevia extracts" for use as food additives. Studies on stevia in those forms raise concerns about the control of blood sugar and effects on the reproductive, cardiovascular, and renal systems, the FDA warns.
However, the FDA has allowed companies to use an isolated chemical from stevia as food additive, calling the chemical "generally recognized as safe." Now, products such as Truvia and others have the legal go-ahead to use Rebaudioside A, which is also found in stevia, in their no-calorie sweeteners.

But there are some health concerns surrounding the stevia plant. Stevia may cause low blood pressure, which would be of concern to some taking blood pressure medications.
"Caution is advised when using medications that may also lower blood sugar. People taking insulin or drugs for diabetes by mouth should be monitored closely by a qualified health care professional, including a pharmacist," Ulbricht said.
Stevia may also interact with anti-fungals, anti-inflammatories, anti-microbials, anti-cancer drugs, anti-virals, appetite suppressants, calcium channel blockers, cholesterol-lowering drugs, drugs that increase urination, fertility agents and other medications, Ulbricht said. People should talk with their doctor before deciding to take stevia in large amounts, she said.
