Some people may have a sensitivity to MSG, but it’s safe for most people when used in moderation. Preservatives are natural or man-made chemicals that are added to foods to stop them from spoiling. The use of thimerosal as a preservative in vaccines has markedly declined due to reformulation and development of new vaccines in single-use presentations. Artificial coloring. Thimerosal as a Preservative Thimerosal is a mercury-containing organic compound (an organomercurial). (Note- one vaccine, Fluvirin’s single-dose presentation utilizes thimerosal as part of its manufacturing process, not as a preservative, and a trace remains in the final presentation). (2002) The three modern faces of mercury. (2009) Mercury levels in premature and low birth weight newborn infants after receipt of thimerosal-containing vaccines J Pediatr. From this experience, the Royal Commission recommended that biological products in which the growth of a pathogenic organism is possible should not be issued in containers for repeated use unless there is a sufficient concentration of antiseptic (preservative) to inhibit bacterial growth. 2003;290:1763–6.

Natural and artificial preservatives are added to many foods to extend shelf life and stop them going bad (food additives). Still, more research is needed to evaluate the safety and potential health effects of artificial food coloring for humans. Food preservatives can be extrinsic (intentionally added), intrinsic (normal constituent of food), or developed (produced during fermentation) (Potter and Hotchkiss, 1995; Jay, 1996). In one study, 61 people who reported being MSG-sensitive were given either 5 grams of MSG or a placebo. Thompson, WW., et al.

(2004) Neurotoxic effects of postnatal thimerosal are mouse strain dependent. One study found that the red blood cell production in rats was significantly reduced after they were fed artificial flavorings for seven days. All vaccines routinely recommended for children 6 years of age and younger in the U.S. are available in formulations that do not contain thimerosal. Madsen KM, Hviid A, Vestergaard M, Schendel D, Wohlfahrt J, et al. Guar gum is high in fiber and has been associated with a multitude of health benefits. A higher intake of nitrites and processed meats may be linked to a higher risk of several types of cancer. However, keep in mind that these studies used a much more concentrated dose than you might find in food, and further research is needed to determine how artificial flavoring in the amounts found in foods may affect humans. However, depending on the vaccine formulations used and the weight of the infant, some infants could have been exposed to cumulative levels of mercury during the first six months of life that exceeded Environmental Protection Agency (EPA) recommended guidelines for safe intake of methylmercury. There is a robust body of peer-reviewed, scientific studies conducted in the United States and countries around the world that support the safety of thimerosal-containing vaccines. The U.S. Food and Drug Administration is the chief federal government agency responsible for regulating vaccines in the U.S. and therefore provides … Immunization Safety Review: Vaccines and Autism. It’s rich in a type of simple sugar called fructose, which can cause serious health issues when consumed in high amounts. FDA Actions Pertaining to Thimerosal in Vaccines. A key word here is artificial and should give you a good indication that something unnatural is in the product. In some cases, preservatives are added during the manufacturing process to prevent microbial growth. Preservatives can keep food fresher for longer periods of time, extending its shelf life. However, not all preservatives are created equal. Xanthan gum has been associated with several health benefits. Chemical food preservatives.

That being said, some people do have a sensitivity to MSG and may experience symptoms like headaches, sweating and numbness after eating a large amount. BioThrax is not recommended for routine use by CDC’s ACIP. Under the FDA Modernization Act of 1997, the FDA compiled a list of regulated products containing mercury, including those with thimerosal (Federal Register 1999). Also the freezing, boiling, smoking, salting are considered to be the natural ways of preserving food. Vaccine Safety: Examine the Evidence. By extension, preservatives reduce food cost, improve convenience, lengthen shelf life and reduce food waste. American Academy of Pediatrics. Such practices date to prehistoric times. Learn about the importance and methods of preservation. Wilson GS. According to the International Institution of Health, here are some of the chemical food preservatives that are widely used-Benzoates (such as sodium benzoate, benzoic acid) Other studies suggest that nitrosamine exposure may also be linked to a higher incidence of type 1 diabetes, although findings are inconsistent (18). It’s found in a variety of processed foods like frozen dinners, salty snacks and canned soups. Mercury accumulates in the aquatic food chain, primarily in the form of the methylmercury, an organomercurial. The risk of contamination of vaccines cannot be completely eliminated even with the use of preservatives. J Appl Toxicol 21(1):1-5.

Regardless, food dyes are found primarily in processed foods, which should be limited in a healthy diet. Thimerosal contains a different form of mercury called ethylmercury. Preservatives are important. A vaccine containing 0.01% thimerosal as a preservative contains 50 micrograms of thimerosal per 0.5 mL dose or approximately 25 micrograms of mercury per 0.5 mL dose. MMWR Surveill Summ 2016;65:1-23. On the 17th, 20th, 21, and 24th January, Dr. Thomson injected subcutaneously a total of 21 children without ill effect. For the same reason, human food has preservatives as well.

Cutting processed foods out of your diet is the easiest and most effective way to decrease your trans fat intake. 2-Phenoxyethanol is an organic chemical compound that is sometimes used in cosmetics and antiseptics. The function of emulsifiers, stabilizer and thickeners in food is to stabilize the emulsions of fat and water so that the product remains stable, not melted, not separated between the fat and water parts and has a compact texture. Test-tube and animal studies have found that carrageenan triggered inflammation, as well (36, 37). The documented antimicrobial properties of thimerosal contribute to the safe use of vaccines in multi-dose vials, and the ability to package certain vaccines, such as those for seasonal and pandemic influenza, in multi-dose vials helps facilitate immunization campaigns in the United States and globally that save lives. Some of these substances have been associated with adverse health effects and should be avoided, while others are safe and can be consumed with minimal risk. It’s also often added to foods at restaurants and fast food places. Note that certain types of artificial sweeteners like aspartame may cause headaches in some people, and studies show that certain individuals may be more sensitive to its effects (32, 33).

Here are 12 of the most common food additives, plus recommendations for which ones to keep out of your diet. The literature contains several reports of bacterial contamination of vaccines despite the presence of a preservative, emphasizing the need for meticulous attention to technique in withdrawing vaccines from multi-dose vials. (2001) An assessment of thimerosal use in childhood vaccines. A population-based study of measles, mumps, and rubella vaccination and autism. This article examines its benefits and side effects to determine how it affects your health.

The Lancet 360:1737-41. Xanthan gum may help reduce levels of blood sugar and cholesterol. Abscesses complicating DTP vaccination. One small study found that when people in remission from ulcerative colitis took a supplement containing carrageenan, they experienced an earlier relapse than those who took a placebo (39). They are used in vaccines to prevent microbial growth in the event that the vaccine is accidentally contaminated, as might occur with repeated puncture of multi-dose vials with a needle. This article takes a look. For example, one study found that combining sodium benzoate with artificial food coloring increased hyperactivity in 3-year-old children (41). The ingredients that serve as emulsifier include egg yolk, egg white (albumin), gelatin, lecithin… Artificial sweeteners may help promote weight loss and blood sugar control. Artificial flavors are chemicals designed to mimic the taste of other ingredients. While the use of mercury-containing preservatives has declined in recent years due to the development of new products formulated into single-dose presentations that do not require preservatives, thimerosal has been used in some immune globulin preparations, anti-venins, skin test antigens, and ophthalmic and nasal products, in addition to some vaccines. If you experience any negative side effects after consuming MSG, it’s best to keep it out of your diet. It has been generally recognized as safe by the FDA, but several studies have uncovered potential side effects that should be considered (40). The scientific evidence collected over the past 15 years does not show any evidence of harm, including serious neurodevelopmental disorders, from use of thimerosal in vaccines. A review of three studies also found that people who took guar gum along with a meal had increased feelings of fullness and ate fewer calories from snacking throughout the day (20). It is also currently used as a preservative in three FDA-approved available vaccines, Pneumovax 23 (for prevention of pneumococcal disease caused by the 23 serotypes contained in the vaccine) and Typhim Vi (for prevention of typhoid fever) and ACAM2000 (for prevention of smallpox); each of these vaccines contains 0.25% phenol. It is used in over-the-counter hand and body washes. Unfortunately, current research on the effects of carrageenan is still very limited and more studies are needed to understand how it may affect people. MSG is used to enhance the flavor of many processed foods. However, this additive is likely to have little to no effect on human brain health as it’s unable to cross the blood-brain barrier (2). An assessment of thimerosal use in childhood vaccines. (2007) Early thimerosal exposure and neuropsychological outcomes at 7 and 10 years. Pichichero ME, Gentile A, Giglio N, Alonso MM, Fernandez Mentaberri MV, Zareba G, Clarkson T, Gotelli C, Gotelli M, Yan L, Treanor J. Nevertheless, guar gum is generally considered safe in moderation. At high exposure levels methylmercury can be toxic to people. This article takes a look at the evidence. It is metabolized or degraded to ethylmercury and thiosalicylate. Not only that, certain flavors like chocolate, biscuit and strawberry were also found to have a toxic effect on their bone marrow cells (55). Xanthan gum is a common additive that’s used to thicken and stabilize many types of food such as salad dressings, soups, syrups and sauces.

Another study showed that consuming sucralose for three months had no effect on blood sugar control in 128 people with diabetes (31). (2005) Are Nitrates and Nitrites in Foods Harmful? Thimerosal is an organomercurial compound and derivative of thiosalicyclic acid with antibacterial and antifungal properties [L1672]. Guar gum may also cause mild symptoms like gas, bloating or cramps in some people (24). Ethylmercury is an organomercurial that should be distinguished from methylmercury, a related substance that has been the focus of considerable study. However, improvements in manufacturing technology have markedly decreased the need to add preservatives during the manufacturing process. Since then, thimerosal has been the subject of numerous studies (see Bibliography- Notable Studies and Assessments Supporting the Safe Use of Thimerosal in Vaccines) and has a long record of safe and effective use preventing bacterial and fungal contamination of vaccines, with no ill effects established other than minor local reactions at the site of injection. It has been associated with better digestive health, lower levels of blood sugar and cholesterol, as well as increased feelings of fullness. However, the use of thimerosal as a preservative in U.S. FDA-licensed vaccines has significantly declined due to reformulation and development of new vaccines presented in single-dose containers. Canned food requires fewer preservatives than dry food as it is protected from oxidation by its airtight storage. Bernier RH, Frank JA, Nolan TF. Xanthan gum is a common food additive that has some people worried, while others claim it has health benefits. Hviid A, Stellfeld M, Wohlfahrt J, Melbye M. Association between thimerosal-containing vaccine and autism. Some animal studies have found that artificial flavoring may be toxic to bone marrow cells. All vaccines routinely recommended for children 6 years of age and younger in the U.S. are available in formulations that do not contain thimerosal. However, most foods only contain a small amount of added yeast extract, so the glutamate and sodium in yeast extract are unlikely to cause much of a problem for most people. This is because it can swell 10 to 20 times its size, potentially causing issues like obstruction of the esophagus or small intestine (23). High-fructose corn syrup is a sweetener made from corn. On the 27th an additional 21 children were injected. Sulphites destroy thiamine (Vitamin B1) so some experts recommend that foods which are a significant source of thiamine, such as meats, dairy foods and cereals should not be sulphited. Thimerosal, which is approximately 50% mercury by weight, has been one of the most widely used preservatives in vaccines. Ball LK, Ball R, Pratt RD. Barregard L, Rekic D, Horvat M, Elmberg L, Lundh T, Zachrisson O. Coffee powder and soup are dehydrated and freeze-dried for preservation. A number of potential health risks have been associated with trans fat intake, and the FDA even recently decided to revoke their GRAS (generally recognized as safe) status (46). Toxicol Sci 101(2):294-309. … Taurine: Taurine is a substance that helps maintain water and electrolyte balance in the blood. Tragic consequences have followed the use of multi-dose vials that did not contain a preservative and have served as the impetus for this requirement. In large amounts, it may cause digestive issues like gas and soft stools. The United States Code of Federal Regulations (the CFR) requires, in general, the addition of a preservative to multi-dose vials of vaccines; and, worldwide, preservatives are routinely added to multi-dose vials of vaccine. It is also currently used as a preservative in one FDA-approved available vaccine, Ipol, for the prevention of polio, at a concentration of 0.5%. As with pediatric vaccines, vaccines for adolescents and adults are available in formulations that do not contain thimerosal. Food dyes are artificial chemicals added to foods in order to change their color. Methylmercury makes its way through the food chain in fish, animals and humans. Food allergy is actually more often caused by the food itself. These are the traditional preservatives in food that are also used at home while making pickles, jams and juices etc. Test-tube and animal studies have also found that fructose can trigger inflammation in the cells (27, 28). Interestingly, 36% experienced an adverse reaction to MSG while only 25% reported a reaction to the placebo, so MSG sensitivity may be a legitimate concern for some people (6). (Note- one vaccine, Tetanus and Diphtheria Toxoids Adsorbed, single-dose presentation, manufactured by Mass Biologics utilizes thimerosal as part of its manufacturing process, not as a preservative, and a trace remains in the final presentation).
