Any subject. Any type of essay. Carcinogens have plagued our society for many years. For example, radon and arsenic have been around since the Paleolithic era. According to the American Cancer Society: Long-term exposure to radon can lead to lung cancer. Radon gas in the air breaks down to other radioactive elements radon progeny. Radon progeny are tiny radioactive particles that can lodge in the lining of the lungs, where they continue to break down into other radioactive elements by releasing radiation American Cancer Society 1. Not only do we have to be conscious of the natural causes, but we have artificially manufactured cancer into everyday habits.
From smoking food additives essay to ingesting processed ingredients as harmless as diet soda, forms of cancer-causing agents inhabit within these products. Food additives essay rays can be found in medical environments used to diagnose patients for broken bones, torn ligaments, and other bodily anomalies. The problem lies not within the use of these instruments, but the control and the amount of allowable concentration before the chemicals inside cause mutations within the cells. Gerard Tortora, Berdell Funke, food additives essay, and Christine Case have stated: A mutation is a permanent change in the base sequence of DNA. Such a change in the base sequence of a gene will sometimes cause a change in the product encoded by that gene. For example, when the gene for an enzyme mutates, the enzyme encoded by the gene may become inactive or less active because its amino acid sequence has changed.
Carcinogens take the place of natural food as quickly as their chemical counterpart has been recalled and taken off the shelf. Although we recognize the problem, the profits gained from the distribution food additives essay certain products outweigh the long-term effects associated with them. John Casely of Nutrition and Food Science reports: The sweet taste of the compound N-L-[alpha]-aspartyl-L-phenylalaninemethyl ester Food additives essay was discovered in December by the pharmaceutical company G. Chemist James Schlatter was synthesising the tetrapeptide gastrin when the APM intermediate spilled on his hand, food additives essay, and because he knew the amino acid mixture was not toxic, he did not bother to wash it off.
For example, what had James Schlatter originally been trying to yield using these chemical components? Esters are primarily aromatic compounds that arise from the combination of a carboxylic acid and an alcohol. Coincidentally, these chemicals also form hydration reactions, increasing combustibility, nuclear activity, and toxicity, food additives essay. Specifically, allowing copious amounts of a harmful substance into the body increases susceptibly of immune system responses, which raises a red flag. The safe or allowable amount food additives essay be ingested should not be in question. You would not ask yourself how long you should be able to expose yourself to the sun until you have cancer.
As farfetched as this may sound, even a small portion of carcinogens may cause mutations genetically, while altering metabolic pathways and decreasing necessary products to make ATP. ATP or Adenosine Triphosphate, known for its necessity in cellular metabolism, fuels energy for cells to replicate, thrive, and survive harsh conditions. However, mutations cause a drastic change in the genetic food additives essay of the genome, while not only altering the processes of transcription of translation, but also severely hindering protein synthesis from making a sufficient protein to catalyze a chemical reaction. For example, Beta-galactosidase primarily breaks down lactose into glucose and galactose.
Food additives essay functions as a catalyst for metabolism, breaking down in the process known as glycolysis, and through the Prep Step, Citric Acid Cycle, and Electron Transport Chain, creates 36 ATP. In the event that Beta-galactosidase cannot be produced, the amount of necessary energy for cellular function lowers to a dangerous level, causing cellular dysfunction and possibly death. Now, you might ask why we do not take action to stop this from occurring. However, the problem lies within the amount of counterevidence suggesting that while these chemicals may pose a threat to the livelihood of modern society, as long as we control the amount we ingest, we do not have to worry about the negative consequences.
An assumption like this shows why proactive campaigns against smoking have become prevalent within the past twenty years. If someone with a shred of credibility can convince the general public its safety does not need to be of concern, everyone turns a blind eye toward the subject and moves on. Food additives essay the other hand, what if the evidence suggesting that chemicals in food preservatives such as nitrates, food additives essay, aspartame, and MSG poses a larger threat than what we have originally believed? Scientific trials might show that exposing mutagens in moderation causes little to no change in the base sequence of DNA within cells, but the problems associated with the chemicals still exist, food additives essay. Today, scientists concoct artificial products with low concentrations of cancer-causing agents found in sweeteners, diet soda, condiments, and even bacon and hot dogs.
We cannot be certain that allowing a small amount of these chemicals to enter our bodies pose no harm to us. We have to stay proactive and conscientious instead of letting someone else think for us. Too often have patients been found in immunocompromised situations under little to no belief from their healthcare provider that anything other than genetic heredity and natural causes have allowed cancer to inhabit their bodies. Although I cannot suggest a valid food additives essay other than avoiding the chemicals associated, I would like to present a credible amount of evidence from well-respected sources in an attempt to raise public awareness about the situation as a whole. Instead of leaving the issue on the backburner, I want to bring the situation to light and inform those who may have been left in the dark about the problem altogether.
First, we must take a look at the overall control distributing these potentially toxic chemicals into the economy. Similar to organizations in the United States, the SCF, FAC, and COT regulate specific products distributed in the United Kingdom to prevent caustic chemicals from being circulated into the economy. Caseley and Dixon have stated: A new additive which requires authorisation [sic] must go through an exhaustive safety assessment process. The manufacturer of the potential new additive must not only produce evidence that there food additives essay a real need for the substance, but also commission research into that substance. The research must include toxicological tests tests to determine whether a substance is harmful including tests to assess the mutagenic potential of the compound, that is the ability to interfere with genetic material in the body, which could lead to the development of cancer or adverse effects in future generations.
The Food and Drug Administration in the United States oversees the distribution of potentially toxic chemicals, food additives essay. However, their concern with aspartame remains absent. As stated before, food additives essay, aspartame contains a dipeptide ester bond within its structure. In order for these chemicals to synthesize, they undergo hydration reactions, which increase combustibility and toxicity. Unstable compounds in even the smallest amounts could have catastrophic effects in the body. First, food additives essay, break apart the simplest component of the compound.
The dipeptide bonds contain nitrogen, hydrogen, and a carbonyl food additives essay that help synthesize them into proteins. Proteins can be denatured or unraveled, making them unstable and possibly harmful in large amounts. Examples food additives essay denaturation include a change in pH, temperature, food additives essay, the presence of salt, reactions with heavy metals, and several other environmental changes. With that being said, our bodies maintain a constant body temperature and pH, depending on the location and current immunological condition. Under a laboratory setting, trace amounts of aspartame have been found to be stable. However, food additives essay, under current environmental conditions within the lab, we have no possible way to maintain homeostasis, let alone test a stable pH.
The human body contains variable pH levels systemically, from the blood to the stomach. Who can say with certainty that ingesting allowable amounts of this chemical in the body will be harmless? Proteins within aspartame must undergo the same chemical reactions that we produce proteins in the body. Translation, food additives essay, also known as protein synthesis, creates a series of amino acid chains that food additives essay into functional proteins. However, one slight change in the sequence of the chain could cause mutations, leading to genetic disorders and even cancer. The problems lies not only within the chemical compounds, but also the way they are handled, food additives essay, synthesized, and broken down in the body.
Until we can confirm that these chemicals pose no threat, the best way to substitute the chemical in foods would be by using its original derivative, pure cane sugar. Along with aspartame, food additives such as nitrates and nitrites also pose potential threats to the sustainability of a healthy life. Food additives essay to researchers from Tufts University: Both compounds contain nitrogen and oxygen; nitrate has an extra oxygen atom. Animal experiments have shown that nitrite-whether directly from food, naturally converted from dietary nitrate or formed from nitric food additives essay combine with other dietary elements to form cancer-causing nitrosamines. However most people believe the consumption of nitrites and nitrates pose no harm, since several organic foods such as vegetables contain both Tortora, Funke, Case While natural compounds within nitrites and nitrates have been found in natural foods, synthesized chemicals remain absent.
Again, we must ask ourselves whether or not the risk factor matters. Nitrite in high doses is also linked with cancer as it can make carcinogenic nitrosamine and N-nitroso compounds. For example, low levels of nitrite may act as a growth signal to cancer cells. He also wonders why nitrite in drinking water seems to be more potent than nitrite in food. It may be, for example, that a continuous low level of nitrite sends a stronger cancer growth signal than high short-term levels fluctuating from a very low base Tickell Given the facts, one might conclude that nitrates and nitrites pose no harm.
For instance, glycolysis, the breaking down of glucose, occurs within the first few steps of making ATP. When carcinogens take over metabolic food additives essay, they undergo reverse transcription, which produces proteins made from RNA or ribosomal nucleic acid. Usually, mRNA codes for specific amino acids from a DNA template. However, when we flip the script, we cause several problems within a cell, including its functionality, behavior, recognition to other cells, food additives essay, and many other issues as well. Food additives essay instance, when a cell recognizes itself as foreign, immune responses signal B cells and T cells to fight the pathogen and destroy the host cell. When our body starts to attack its own cells, we find ourselves in immunocompromised situations.
A far stretch to the imagination as this may seem, the truth lies within the science supporting the claim. The more caustic substances we put into our body, the higher the chances of receiving such conditions. Finally, food allergies have been found prevalent in food additives, increasing hypersensitivity and immune system food additives essay. Food allergy hypersensitivity is due to an immunologic reaction resulting from the ingestion of a food. For instance, anything the body recognizes as foreign immediately sends a response to basophils, specific white blood cells that release histamine, a chemical used in alleviating allergic reactions. However, when too much histamine released from the basophil does not alleviate symptoms, separate white blood cells arrive and try to destroy the antigen, while potentially harming healthy human cells as well Goode Doguc and Gultekin continue their analysis: The spectrum of food-induced reactions ranges from benign manifestations of disease, such as flushing or rhinorrhea to life-threatening symptoms such as systemic anaphylaxis with shock or enterocolitis syndrome.
Following immunemediated [sic] mechanisms are the basic mechanisms of adverse food reactions: IgE-mediated, non-IgE-mediated, eosinophilic disorders and allergic responses due to combinations of immune mechanisms. The most usual type of food allergy occurs due to IgE-mediated mechanism, of which anaphylaxis should be the best example for this type of allergy. When these types of white blood cells become disrupted and can no longer function, pathogens we could fight off before can easily enter the body and harm healthy cells Goode Specifically, food additives essay antigens start to target white blood cells, causing autoimmunity, food additives essay, we have little to no defense against symptoms as common as the flu.
Food additives increase the chances of these responses occurring, especially to those who have been genetically predisposed to allergens. These agencies have performed tests to prevent one possible outcome, but with one comes two more. We always expose ourselves to risks when we delve into what cannot be controlled, food additives essay, especially concerning chemicals. Even the slightest change could drastically affect the chemical composition within the body. Although I cannot prevent everyone from ingesting such chemicals, I can inform with valid claims and supporting arguments. I will leave it up to the reader to evaluate whether the risk factor outweighs the urge to consume.

When these types of white blood cells become disrupted and can no longer function, pathogens we could fight off before can easily enter the body and harm healthy cells Goode This food additives essay is basically an advantages and disadvantages essay.
Do the dangers derived from the use of chemicals in food production and preservation outweigh the advantages? In my opinion, the potential dangers from this are greater than the benefits we receive. However, make sure your essay supports your opinion. For example, if you have said there are more disadvantages, it would not make sense to then write mostly about advantages. As you can see from the model answer, advantages are discussed, but the focus is on the disadvantages as this is what it is stated are greater in the thesis statement.
You should spend about 40 minutes on this task. Give reasons for your answer and include any relevant examples from your own experience or knowledge. Most foods that are purchased these days in small stores and supermarkets have chemicals in them as these are used to improve production and ensure the food lasts for longer. However, there are concerns that these have harmful effects. There are several reasons why chemicals are placed in food. Firstly, it is to improve the product to the eye, and this is achieved via the use of colourings which encourage people to purchase food that may otherwise not look tempting to eat.
Another reason is to preserve the food. Much of the food we eat would not actually last that long if it were not for chemicals they contain, so again this is an advantage to the companies that sell food as their products have a longer shelf life. From this evidence, it is clear to me that the main benefits are, therefore, to the companies and not to the customer. Although companies claim these food additives are safe and they have research to support this, the research is quite possibly biased as it comes from their own companies or people with connections to these companies. It is common to read reports these days in the press about possible links to various health issues such as cancer. Food additives have also been linked to problems such as hyperactivity in children.
To conclude, despite the fact that there are benefits to placing chemicals in food, I believe that these principally help the companies but could be a danger to the public. It is unlikely that this practice can be stopped, so food must be clearly labeled and it is my hope that organic products will become more readily available at reasonable prices to all.
