While there are vastly differing opinions on the health benefits or detriments of soy lecithin, it is still easy to explain who would not want to use it: People with severe soy allergies who want to play it safe. People who avoid refined oils – soy lecithin is made from soy oil, which is usually made through a chemical process using hexane. People concerned about GMOs.  Unless a product is certified non-GMO, you can assume that the soybeans used have been genetically modified.  Products marked non-GMO or USDA organic should be non-GMO, but have been found on occasion to contai..
Acesulfame potassium  also known as Acesulfame K or Ace K is 180-200 times sweeter than table sugar. Although it has been approved by the Food and Drug Administration, its safety is still questioned by bodies such as the Center for Science in the Public Interest (CSPI). During the manufacture of acesulfame potassium, methylene chloride is used as a solvent, which otherwise is used in other commercial applications like paint stripper, degreaser and propellant gas. Its use in the food industry is contentious, and exposure to this chemical compound over a prolonged period of time can result ..
Carrageenan is safe for most people in food amounts. There is a chemically altered form of carrageenan that is available in France to treat peptic ulcers. This form might be UNSAFE because there's some evidence that it might cause cancer.   ..
LIKELY SAFE for most people. Side effects are usually mild. Some people have reported dizziness, headache, nausea, vomiting, constipation, anddiarrhea.

There is some concern that saw palmetto might cause liver or pancreas problems in some people. There have been two reports of liver damage and one report of pancreas damage in people who took saw palmetto. But there is not enough information ..
Pyridoxine is LIKELY SAFE for most people. In some people, pyridoxine might cause nausea, vomiting, stomach pain, loss of appetite, headache, tingling, sleepiness, and other side effects. Long-term use of high doses is POSSIBLY UNSAFE. It might cause certain brain and nerve problems. Special Precautions & Warnings: Pregnancy and breast-feeding: Pyridoxine is LIKELY SAFE for pregnant women when taken under the supervision of their healthcare provider.

Synthetic fats, produced from glycerol and natural fatty acids, mainly from plant origin, but also fats of animal origin may be used. The product generally is a mixture of different products, with a composition similar to partially digested fat. The body metabolises the products as any other fat. The individual components are also produced normally in the body when digesting normal fat. Although mainly vegetable oils are used, the use of animal fat (incl. pork) can not be excluded. Several groups, such as vegans, Muslims and Jews thus avoid these products. Only the producer can give detailed i..
Polydextrose is a synthetic food additive. Acting as a bulking agent to enhance the taste is commonly used as a substitute for sugar, starch and fat in many commercial food products. Polydextrose is generally well tolerated in those who use it in moderation. However, in large quantities or in particularly sensitive people, polydextrose can cause a variety of side effects, including abdominal cramping, bloating and excessive gas. Those who are newly integrating polydextrose into the diet should begin with small amounts, as new users may experience a laxative effect.   ..
Can produce adverse reactions in sensitive people - aspirin allergy or asthmatics. Reactions include nettle rash and oedema. ..
In the United States, the U.S. Food and Drug Administration banned the sale of cyclamate in October of 1969 after lab tests in rats involving a 10:1 mixture of cyclamate and saccharin indicated that large amounts of cyclamates causes bladder cancer, a disease to which rats are particularly susceptible. Cyclamates are still used as sweeteners in many parts of the world, including Europe. A 2003 paper reports the first epidemiological study designed to investigate the possibility of a relationship between cyclamate and cyclohexylamine and male fert..
There is insufficient reliable information available about the safety of D-phenylalanine. Special Precautions & Warnings: Pregnancy and breast-feeding: Having too much phenylalanine in the mother’s system during pregnancy can increase the chances of birth defects.  Phenylketonuria (PKU) and other conditions that cause high levels of phenylalanine: Phenylalanine should be avoided in people with certain inherited disorders that cause their bodies to build up too much phenylalanine.  People with this disorder can develop mental retardation, high blood pressure..
In 2006, the European Ramazzini Foundation published a study on aspartame consumption in rats and linked its consumption to an increase in the incidence of cancer. There are over 92 different health side effects associated with Aspartame consumption. Aspartame dissolves into solution and can therefore travel throughout the body and deposit within any tissue. The body digests aspartame unlike saccharin, which does not break down within humans easly. Depending on the quantities, you could experience the following side effects after consuming a large quantity of aspart..
Vegetable gums are failsafe. Guar and xanthan are used extensively by coeliacs. Carrageenan (407) used in  some yoghurts, icecreams and some health suppliments and has been linked to cancer and is not recommended in large quantities for young children.   ..
Side effects include increased gas production, diarrhea, and loose stools. These side effects usually decrease or disappear after several days of use. High doses of guar gum or not drinking enough fluid with the dose of guar gum can cause blockage of the esophagus and the intestines. Special Precautions & Warnings: Pregnancy and breast-feeding: Taking guar gum during pregnancy in typical amounts is POSSIBLY SAFE. But not enough is known about the safety of taking guar gum during breast-feeding. Stay on the safe side and avoid use. Gastrointestinal (GI) obs..
Acesulfame-K is a potassium salt containing methylene chloride, a known carcinogen. Reported side effects include; nausea, headaches, mood problems, impairment of the liver and kidneys, problems with eyesight and possibly cancer. Acesulfame-K may contribute to hypoglemica. Among all artificial sweeteners, Acesulfame-K has undergone the least scientific scrutiny. Early studies showed a potential link between the sweetener and development of multiple cancers in laboratory animals.  ..
Long term use of Anticaking Agent (551) or(Silicon dioxide) has been shown to give kidney damage in some studies  .People with pre-existing kidney or heart disease are at a much higher risk if you have a medical history of either cardiac or kidney disease, it is strongly advised that you avoid taking Silicon Dioxide. Long term use of silicon supplementation may further increase the diuretic effects and possibly lead to dehydration, advises the University of Maryland Medical Center. A further health problem that may result from excess urination is hypokalemia. ..
