As people in the United States have become more health conscious, the use of products made with artificial sweeteners has increased. People are naturally attracted to foods that taste sweet.
It has been stated that the taste of sugar may even be addictive. The next year Wiley won a small victory. Industry lawyers fought back, and regulators wavered. Instead, it argued against replacing sugar with saccharin because the former possessed food value while the latter did not. Of course, this point made saccharin immensely popular for dieters since it provided sweetness without calories. The ban on saccharin in processed food was the outcome of a bureaucratic stalemate between regulators and industry.
No incontrovertible evidence proved saccharin harmful at regular doses. Whatever its scientific merit, the prohibition had little effect on public perception. When World War I caused a sugar shortage and consequent price spike, Monsanto, then the largest saccharin producer, took its case to the public in full-page ads, arguing that widespread use of saccharin could save the country millions of dollars.
Price-conscious consumers responded, buying up saccharin tablets for 15 cents a box at local drugstores. When the war ended, saccharin use dipped as consumers returned to sugar.
But post—World War II, changing American eating habits meant saccharin soon became more than just an alternative sweetener. Had saccharin remained merely a sugar alternative, important only to a relatively small number of diabetics and weight watchers during peacetime, it probably would not have caught the eye of government regulators and scientists. In the aftermath of World War II, though, saccharin production remained high.
Fundamental changes in the American diet meant fewer people prepared meals at home, relying instead on preprocessed food. Presweetened products, often containing inexpensive saccharin—the output of an increasingly large food-processing industry—alarmed nutritionists, regulators, and health officials.
While saccharin consumption increased, the debate over its safety was never truly settled. Science, to the public, had issued too many contradictory or inconclusive opinions, so when the decision about saccharin fell to individuals, most responded to their desire for a no-consequences sweetener.
Others, like Harvey Washington Wiley before them, were skeptical. Avis DeVoto, a friend of Julia Child and an editor at Alfred Knopf, remained unimpressed by saccharin, especially by its increasing use in cookbooks. Partly in response to growing unease among regulators and the public, Congress passed the Food Additives Amendment in In preparing its legislation Congress heard testimony from members of the scientific community.
For the first time in connection with food additives, scientists used the c-word: cancer. Representative James J. Delaney, a Democrat from New York, pushed hard for the addition of language specifically outlawing carcinogens. Seemingly uncontroversial at the time—who would support adding cancer-causing agents to food? Legislators had disastrously underestimated the data necessary to definitively declare a substance carcinogenic. The two chemicals balanced each other, with cyclamate blunting the bitter aftertaste of saccharin.
Meanwhile, the use of artificial sweeteners continued to increase among weight-conscious consumers. In Constantin Fahlberg had declared saccharin harmless because he suffered no adverse effects 24 hours after taking a single dose. But post—World War II health science had begun investigating subtler, long-term effects.
Research methodology had changed accordingly: studies observed a longer span of time, for example, and tried to control for a wider range of variables. Researchers shifted away from unstructured human testing toward animal testing that included control groups. Such research produced more and better data but increased complexity. In the late s three trends converged: increasing government regulation in the food-processing industry, the rise of artificial sweeteners, and the growing complexity and sophistication of health science.
It was shown that there was no difference between the results for aspartame and those for the placebo. The effect of aspartame during reproduction, development and lactation has been evaluated in rats, mice, hamsters, and rabbits. The effect of aspartame on behavior, cognitive function, and seizures has been studied extensively in animals, and in healthy children, hyperactive children, sugar-sensitive children, healthy adults, individuals with Parkinson's disease, and individuals suffering from depression.
The effects of aspartic acid , another aspartame breakdown product, have also been rigorously examined. Administration of extremely large amounts to non-human primates produced no damage even though blood levels were greatly elevated. It is a fact that in large doses, methanol can lead to blindness and even to death. Methanol occurs naturally in foods. Even at the 99 th percentile level of 34 mg per kg of body weight consumed per day, blood levels of methanol are undetectable.
Nitrosoureas are indeed known to produce brain tumors in animals. However, in the European Food Safety Authority reviewed the study and concluded that the tumors probably occurred just by chance. National Cancer Institute researchers studied a large number of adults 50 to 69 years of age over a five-year period. There was no evidence that aspartame posed any risk. However, the study was limited in three major regards: It did not involve truly elderly people the rat studies monitored the rats until they died a natural death , the subjects had not consumed aspartame as children, and it was not a controlled study the subjects provided only a rough estimate of their aspartame consumption, and people who consumed aspartame might have had other dietary or lifestyle differences that obscured the chemical's effects.
The Italian tests remain controversial, with the industry contending that they were flawed in several ways and with the FDA stating that its scientists could not evaluate the studies because the researchers refused to provide their original data. The objectives of the Organizing Team were to identify, collect and review all published papers since the review carried out by the SCF Scientific Committee on Food in In addition the Organizing Team considered available non-peer-reviewed information and anecdotal evidence.
They analyzed 26 reviews. The areas which were considered include exposure data, brain function, satiation and appetite, allergenicity and immunotoxicity, metabolic aspects and diabetes, carcinogenicity including cancer epidemiology and genotoxicity and reported on. The National Experts consider, however, that the scientific literature needs to be monitored for further research and mechanistic explanations related to this area.
The National Experts note that no new publications were identified reporting a link between aspartame intake and enhanced susceptibility to seizures, behavior, mood and cognitive function, and conclude that there is still no substantive evidence that aspartame can induce such effects, as earlier concluded by the SCF. A study focusing on aspartame, such as that performed by Just et al.
In the literature reviewed by the Organizing Team it has been observed that the metabolites of aspartame aspartic acid, phenylalanine and methanol could affect the metabolism of endogenous and exogenous compounds. Amino acids per se have an influence on metabolic pathways and it is known that high doses of aspartame may increase plasma levels of the metabolites of aspartame.
High levels of specific amino acids can also affect transporters and protein synthesis. The National Experts note that there is very little new information about the effects of aspartame and its metabolites on the metabolism of endogenous and exogenous compounds. The available reports mainly used high doses, and focused on plasma changes in aspartic acid, phenylalanine and methanol.
The National Experts considered that research investigating whether aspartame and its metabolites affect gene expression, protein synthesis and enzyme activities of Cytochrome P enzymes in the brain could be useful to extend knowledge in this area. While the use of novel techniques such as metabolomics has not been considered in previous evaluations of aspartame, as they were not available at the time, it is recognized that such research is at the forefront of toxicological science and the results of such work may usefully increase the evidence base.
There is no evidence to suggest that aspartame is carcinogenic as discussed earlier. Overall, National experts of EFSA in have not identified any new evidence regarding the safety of aspartame. The current weight of evidence is that aspartame is safe at current levels of consumption as a nonnutritive sweetener.
Saccharin was discovered over a century ago and has been used as a non-caloric sweetener in foods and beverages for more than years.
Apart from Sugar of lead, Saccharin was the first artificial sweetener and was originally synthesized in by Remsen and Fahlberg. It had been created in an experiment with toluene derivatives. A process for the synthesis of saccharin from phthalic anhydride was developed in and currently, saccharin is synthesized by this process as well as the original process by which it was discovered. It is to times sweeter than sugar and is often used to improve the taste of toothpastes, dietary foods, and dietary beverages.
One animal study has shown that consumption of products containing saccharin may lead to increased body weight and obesity by interfering with fundamental homeostatic and physiological processes[ 15 ] Fear about saccharin increased when a study in showed that high levels of saccharin may cause bladder cancer in laboratory rats.
In , Canada banned saccharin due to the adverse effects reported in animal studies. In the United States, the FDA considered banning it in , but Congress stepped in and placed a moratorium on such a ban which required a warning label and also mandated further study of saccharin safety. Subsequently, it was discovered that saccharin causes cancer in male rats by a mechanism not found in humans.
At high doses, it forms a precipitate in rat urine. This precipitate damages the cells lining the bladder and a tumor forms when the cells regenerate.
In May , the U. Department of Health and Human Services removed saccharin from its list of cancer-causing chemicals. Later that year, Congress passed a law removing the warning notice that likely will result in increased use in soft drinks and other foods and in a slightly greater incidence of cancer. In , the United States repealed the warning label requirement, while the threat of an FDA ban had already been lifted in Most other countries also permit saccharin but restrict the levels of its use, while other countries have outright banned it.
Sucralose was discovered by British researchers in It is the only non-caloric sweetener made from sugar and considered as a latest international Zero-Calorie sugar substitute. It is a chlorinated sugar that is about times as sweet as sugar.
It is produced from sucrose when three chlorine atoms replace three hydroxyl groups. Its unique combination of sugar-like taste and excellent stability allow sucralose to be used as a replacement for sugar in virtually every type of food more than 4, food products and beverages, frozen desserts, chewing gum, baked goods, and other foods.
Unlike other artificial sweeteners, it is stable when heated and can therefore be used in baked and fried goods. Sucralose is minimally absorbed by the body and most of it passes out of the body unchanged.
The establishment of an ADI for sucralose required some additional research beyond the routine studies ordinarily carried out to evaluate the safety of a food additive. Safety concerns pertaining to sucralose revolve around the fact that it belongs to a class of chemicals called organic chlorides, some types of which are toxic or carcinogenic; however, the presence of chlorine in an organic compound does not in any way ensure toxicity.
The way sucralose is metabolized may suggest a reduced risk of toxicity. For example, sucralose is extremely insoluble in fat and thus does not accumulate in fat as do some other organic chlorides; sucralose also does not break down and dechlorinates only under conditions that are not found during regular digestion.
Sucralose is considered safe for all segments of the population, including people with chronic health problems such as diabetes. A three-month study of people with diabetes, in which sucralose was administered at a dose approximately three times the maximum estimated daily intake, showed no adverse effects on any measure of blood glucose control. Acesulfame potassium is a non-caloric sweetener with a clean, quickly perceptible sweet taste.
It has excellent stability under high temperatures and has good solubility. So it is suitable for numerous products. In , acesulfame K was approved by the US FDA for use in liquid non-alcoholic beverages and in , general use approval was granted. Neotame is a no-calorie sweetener, which is a derivative of the dipeptide composed of the amino acids, aspartic acid and phenylalanine. Advertisements fund this website.
