  • Food Additives - 1,055 words
    Food Additives Food Additives Food additives have been used for thousands of years. In prehistoric times, salt was probably used to preserve meat and fish. Our ancestors also found that large amounts of sugar helped preserve fruit and that cucumbers could be preserved in a vinegar solution. The ancient Egyptians used sulfites to stop bacterial growth and fermentation in wine. They also used extracts from beetles for food coloring. Vegetable dyes from juniper fruits or beech-root juice were popular colorings in the Middle Ages, although wary kings began to employ garglers to test their mealsperhaps for additives that did not originate in the kitchen (Editors of Prevention Magazine 1993).

FSIS and FDA work with the industry to ensure that material used in processing and packaging meat and poultry products are safe, perform their intended function, and comply with food safety laws (FDA 1998). In their book, The Rubbish On Our Plates, Perucca and Pouradier warn that many of the late twentieth centurys major diseases, such as Alzheimers and cancer, can be traced to the chemicals in our food from both industrial farming and environmental pollution. They also believe that the modern multi-national food industry is so complex and fast moving that it is impossible for the authorities to monitor the proliferation of new chemicals and irregular practices (Pe ...

  • Adhd - 931 words
    Adhd Attention Deficit Hyperactivity Disorder Attention deficit hyperactivity disorder (ADHD) is one of the most common mental disorders among children. About 3 percent to 5 percent of American children are affected by this disorder. This disorder is commonly mis-diagnosed in children who are very hyperactive, assuming that very hyperactive kids have this disorder. In this paper I plan to discuss ideas such as: the symptoms, theories of causation, risks, and how this disorder is looked at and treated. There are signs that a child may be affected by ADHD, which are very noticeable in some cases. Some of the physical symptoms that are involved include hyperactivity, inattention, and impulsitiv ...

  • Air Pollution - 1,546 words
    Air Pollution Air Pollution is addition of harmful substances to the atmosphere resulting in damage to the environment, human health, and quality of life. One of many forms of pollution, air pollution occurs inside homes, schools, and offices; in cities; across continents; and even globally. Air pollution makes people sick, it causes breathing problems and promotes cancer, and it harms plants, animals, and the ecosystems in which they live. Some air pollutants return to earth in the form of acid rain and snow, which corrode statues and buildings, damage crops and forests, and make lakes and streams unsuitable for fish and other plant and animal life. Pollution is changing the earth's atmosph ...

  • Allergies - 1,744 words
    Allergies An allergy is an abnormal reaction to ordinarily harmless substance or substances. These sensitizing substances, called allergens, may be inhaled, swallowed or come into contact with the skin. When an allergen is absorbed into the body it triggers white blood cells to produce IgE antibodies. These antibodies attach themselves to mast cells causing release of potent chemical mediators such as histamine, causing typical allergic symptoms. A person who has allergies doesnt have a poor immune system, rather an over protective one. Their immune system fights the allergen when it comes in contact with it even though the allergen isnt harmful. To diagnose allergies a physician will clean ...

  • Animal Testing - 1,180 words
    Animal Testing Medicines, household products, food, and basically everything involved in the life of an average person has to under go a form of testing before it is legal to be placed on a shelf and if available to the public. The same tests are performed on every medical procedure that is introduced to surgeons. Since the only way to directly mimic the human body is to use it itself, scientists were forced to find the closest and best alternative. That is where animals were introduced to the medical profession. Experimentation on animals date back to as early as 500 BC, making this form of medical validation one of the oldest known to humans. It is not only one of the oldest but one of the ...

  • Antibiotics - 1,650 words
    Antibiotics Antibiotics have played a major role in our society thanks to Sir Alexander Fleming's careful observations in 1928. Without it, many lives would be in danger due to infectious diseases. Antibiotics are chemical substances produced by various species of microorganisms and other living systems that are capable in small concentrations of inhibiting the growth of or killing bacteria and other microorganisms. These organisms can be bacteria, viruses, fungi, or animals called protozoa. A particular group of these agents is made up of drugs called antibiotics, from the Greek word anti ("against") and bios ("life"). Some antibiotics are produced from living organisms such as bacteria, fu ...

    Attention Deficit Hyperactivity Disorder Understanding the Behavioral Disorder: Attention Deficit Hyperactivity Disorder (ADHD) Imagine living in a fast-moving kaleidoscope, where sounds, images, and thoughts are constantly shifting. Feeling easily bored, yet helpless to keep your mind on tasks you need to complete. Distracted by unimportant sights and sounds, your mind drives you from one thought or activity to the next. Perhaps you are so wrapped up in a collage of thoughts and images that you don't notice when someone speaks to you. "Tommy can't sit still. He is disruptive at school with his constant talking and clowning around. He leaves the classroom without the teacher's permission. Al ...

  • Clean Air Act - 1,133 words
    Clean Air Act 1990, the federal Clean Air Act was passed to improve air quality in the United States. President Bush's proposed amendments to the Clean Air Act initially would have led to the introduction of alternative, non-petroleum fuels. The petroleum and oxygenate industries responded by offering a reformulated gasoline program as a substitute for most of the alternate fuel proposals. As a result, the amendments to the federal Clean Air Act adopted in 1990 required steps to achieve lower vehicle emissions, including programs to oxygenate and reformulate gasoline. Oxygenated gasoline is designed to increase the combustion efficiency of gasoline, thereby reducing carbon monoxide emissions ...

  • Cost Of Stability In Brave New World - 1,631 words
    Cost Of Stability In Brave New World The Cost of Stability in Brave New World David Grayson once said that Commandment Number One of any truly civilized society is this: Let people be different. Difference, or individuality, however, may not be possible under a dictatorial government. Aldous Huxley's satirical novel Brave New World shows that a government-controlled society often places restraints upon its citizens, which results in a loss of social and mental freedom. The conditioning of the citizens, the categorical division of society, and the censorship of art and religion carry out these methods of limiting human behavior. Conditioning the citizens to like what they have and reject what ...

  • Death Returns To Formula One Racing - 1,178 words
    Death Returns To Formula One Racing Jesse Oleet !0/5/98 English 10 Short Story Death Returns to Formula One Racing My first hint that something was wrong came Sunday afternoon when I logged on to the BBS (bulletin board service, a central computer acting as a host for other users to exchange messages) for auto racing. Someone posted a short but gripping note, I think I just witnessed the death of Ayrton Senna, he said. My eyes widened as I exclaimed what, in shock and dismay. A few hours later, the facts became clearer. Senna had crashed on the sixth lap of the San Marino Grand Prix while leading the race. It happened at a section called Tamburello - a gentle bend taken at top speed, about 1 ...

  • Evironmentalism - 2,824 words
    Evironmentalism Evironmentalism: The Next Step Broad Social Change Through Personal Commitment Introduction In the last thirty years, America has witnessed an environmental revolution. New laws like the 1963 Clean Air Act and the 1974 Safe Drinking Water Act forged new ground in political environmentalism. Social phenomena like Earth Day, organized by Dennis Hayes in 1970, and the beginning of large-scale recycling, marked by Oregon's 1972 Bottle Bill, have help change the way Americans think about the environment. As we approach the third millennium, however, we must reconsider our place on the planet and reflect on our efforts and progress towards a sustainable society. As global warming b ...
