Sugar substitutes can be divided into four general categories: artificial sweetener, sugar alcohols, natural sweeteners, and dietary supplements such as Stevia and Lo Han
Artificial sweeteners can actually be far worse for you than sugar and fructose, and scientific evidence backs up that conclusion
Furthermore, numerous studies show they increase weight gain and worsen insulin sensitivity to a greater degree than sugar
Natural sweeteners such as honey and agave may seem like a healthier choice, but not only are they loaded with fructose, many are also highly processed
In moderation, some sugar alcohols can be a better choice than highly refined sugar, fructose or artificial sweeteners. Of the various sugar alcohols, xylitol is one of the best. When it is pure, the potential side effects are minimal
Three of the best sugar substitutes are all-natural Stevia from the whole plant, Lo Han Guo, and dextrose (pure glucose). Contrary to fructose, glucose can be used directly by every cell in your body and as such is a far safer sugar alternative


different sugar substitutes, which fall into four general categories:
•Artificial sweeteners
•Sugar alcohols
•Natural sweeteners
•Dietary supplements

(Reuters) - U.S. health regulators warned Hain Celestial Group Inc. about a potentially unsafe herb in some of its teas, saying it might be dangerous to blood sugar, reproductive, cardiovascular and renal systems.
The U.S. Food and Drug Administration sent a letter to Hain, dated August 17, calling the herb, a natural sweetener made from a South American herb called stevia, "an unsafe food additive." The agency released the letter on its Web site on Tuesday.
Stevia, derived from a South American herb and several hundred times sweeter than sugar but with no calories, is approved as a dietary supplement, but not as a food additive in the U.S.
Boulder, Colorado-based Hain said in a statement the FDA agreed that the company could change the products' labels to reflect that they are supplements and not food.
這是2007 年路透社文章!!
......Stevia is being eyed by big beverage makers looking for new low-calorie sweeteners. In May, Coca-Cola Co and Cargill Inc said they would work together to develop and market a new sweetener using stevia. While not approved as a food additive in the United States, stevia has been approved in a dozen other countries including Japan, China and Brazil
Stevia(甜葉)是中南美洲使用1500年以上的茶飲,日本是在1970 年代引入日本種植!!!

Siraitia grosvenorii is an herbaceous perennial vine of the Cucurbitaceae (gourd) family, native to southern China and northern Thailand. The plant is cultivated for its fruit, whos
extract is nearly 300 times sweeter than sugar and has been used in China as a natural low-calorie sweetener for cooling drinks, and in traditional Chinese medicine to treat diabetes and obesity---羅漢果!!!從唐代就是漢藥了, 主制肺炎(止咳化痰!!)....請自己參考!!!

Story at-a-glance
Despite being promoted for weight loss, foods and beverages with artificial sweeteners have never been proven to help weight loss. In fact studies that look at this actually find artificial sweeteners promote weight gain
Research has also demonstrated that aspartame worsens insulin sensitivity to a greater degree than sugar, posing a hidden health threat to diabetics who follow the recommendation to switch to diet sodas to manage their condition
To combat the bad publicity, Coca-Cola has resorted to fake “infomercials” that look like public service announcements touting the “scientifically proven” safety and benefits of aspartame for those struggling with their weight
The most comprehensive and longest human study looking at aspartame toxicity found a clear association between aspartame consumption and non-Hodgkin's Lymphoma and leukemia


Ditching ALL sweetened beverages can go a long way toward reducing your risk for chronic health problems and weight gain. Your best, most cost effective choice of beverage is pure filtered tap water
Diet Sodas May Double Your Risk of Obesity
June 30, 2005 | 40,002 views--Mercola com.

The prevalence of obesity has reached epidemic proportions and many Americans are making efforts to side-step extra calories. They are turning to diet soft drinks -- Diet Coke, Pepsi, Dr. Pepper and Sprite -- as their beverage of choice.
University of Texas San Antonio, middle-aged adults who drink diet soft drinks may be drastically increasing their risks of gaining weight later on.
• Participants were 65 percent more likely to be overweight if they consumed one diet soda a day compared to if they drank none.
• Two or more low- or no-calorie soft drinks raised the odds of becoming obese or overweight even higher.
• Those who drank diet soda had a greater chance of becoming overweight than participants who drank regular soda.

his article explores the hypothesis that migraine with aura is associated with a state of central neuronal hyperexcitability. The authors propose that this central neuronal hyperexcitability involves overactivity of the excitatory amino acids, glutamate, and possibly aspartate. Stimuli that activate the migraine attack evoke neuronal depolarization, slow depolarization shifts, and spreading suppression of spontaneous neuronal activity possible by glutamate and K+ dependent mechanisms. A low brain Mg2+ and consequent reduced gating of glutamatergic receptors may provide the link between the physiologic threshold for a migraine attack and the mechanisms of the attack itself by promoting glutamate hyperactivity, neuronal hyperexcitability, and susceptibility to glutamate-dependent spreading depression

Despite the widespread use of chemical food additives, few criteria exist to evaluate consumer reports of adverse reactions.
We analyzed 231 consumer complaints associated with the food additive aspartame. We developed a methodologic approach to evaluate all complaints by adapting general criteria used to investigate adverse reactions to medications. Complaints were ranked according to the effects of cessation and rechallenge. Using this method, we found no clear symptom complex that suggests a widespread public health hazard associated with aspartame use; however, we identified some case reports in which the symptoms may be attributable to aspartame in commonly-consumed amounts. The systematic application of pre-defined review criteria, such as those described here, to monitor consumer complaints related to food additives will help identify products that warrant more focused clinical studies.

The use of the artificial sweetener, aspartame, has long been contemplated and studied by various researchers, and people are concerned about its negative effects. Aspartame is composed of phenylalanine (50%), aspartic acid (40%) and methanol (10%). Phenylalanine plays an important role in neurotransmitter regulation, whereas aspartic acid is also thought to play a role as an excitatory neurotransmitter in the central nervous system. Glutamate, asparagines and glutamine are formed from their precursor, aspartic acid. Methanol, which forms 10% of the broken down product, is converted in the body to formate, which can either be excreted or can give rise to formaldehyde, diketopiperazine (a carcinogen) and a number of other highly toxic derivatives. Previously, it has been reported that consumption of aspartame could cause neurological and behavioural disturbances in sensitive individuals. Headaches, insomnia and seizures are also some of the neurological effects that have been encountered, and these may be accredited to changes in regional brain concentrations of catecholamines, which include norepinephrine, epinephrine and dopamine. The aim of this study was to discuss the direct and indirect cellular effects of aspartame on the brain, and we propose that excessive aspartame ingestion might be involved in the pathogenesis of certain mental disorders (DSM-IV-TR 2000) and also in compromised learning and emotional functioning.
