The best sweetener is sugar free Natura. It is sugar derivative by adding a molecule of chlorine to sugar molecule know as Sucrolose.

Rajagaya, prevention.com has the following negatives on Natura (Sucrolose):

That little yellow packet may not be so innocent. Sucralose—the no-calorie sugar substitute most commonly known by the brand name Splenda—has been found to cause a variety of harmful biological effects in the body, according to a new research review published in the Journal of Toxicology and Environmental Health, Part B: Critical Reviews.

Early research said that sucralose passes through your GI tract undigested, so the theory was that it had little to no effect on you. But new studies show that sucralose is actually metabolized, says study coauthor Susan S. Schiffman, PhD, an adjunct professor at North Carolina State University. Enter a slew of problems, including:

Reduces good gut bacteria: Sucralose alters the amount and quality of those beneficial microbes that hang out in your belly (the same ones found in yogurt) by 50% or more. “Alteration in bacterial counts is associated with weight gain and obesity,” says Dr. Schiffman.

Makes meds less effective: The sugar substitute limits the absorption of therapeutic drugs, such as those for cancer and heart disease, rendering them less effective.

Releases toxins: Many people bake with Splenda to reduce the calories in a recipe, but it decomposes during baking, which releases potentially toxic compounds called chloroproanols.

May alter your body's responses: Sucralose can alter insulin responses and blood sugar levels, has been associated with inflammatory bowel disease, and may even alter genes, the researchers note.

Now, let’s put the research in perspective. It was performed on rats, and rats are obviously not humans. However, the FDA’s approval of how much sucralose can be consumed safely is also based on rat studies, so it’s a fair comparison.

The research also used amounts that are approved for use in food, not megadoses, and some adverse effects were seen at very low levels. For example, says Dr. Schiffman, drinking the equivalent of less than a diet soda a day was found to reduce good gut bacteria, and two diet sodas a day could limit drug absorption.

Other research published in Trends in Endocrinology & Metabolism in 2013 found that sugar substitutes are linked to type 2 diabetes, heart disease, metabolic syndrome, and obesity. So if you want something sweet, your best option is regular sugar in moderation—no more than 100 calories, or six added teaspoons a day, per the American Heart Association’s recommendations

What about stevia ? How much safe it is ?

[norreal in reply to universal]

There is one study which suggests Stevia may help reverse diabetes. It is an in thing now. There aren't enough studies yet to determine side effects.

[patliputra in reply to norreal]

A good one. Congrats.

Let us not hear tomorrow that this or that has been tried n human-rats!!!!

[mrcav]

it is research. wht has been repoted from the research resurlts may be altered and it takes much time to draw a final result. hence one should not abuse results.

Best for Diabetics is not to use any sweeteners. Allofthem are chemicals not good for the system.
