Vitamins
What Are Vitamins?
Vitamins are a group of organic food substances or nutrients found only in living things, plants and animals. They are needed to maintain normal body functions. The body cannot synthesize its own vitamins so we must get our vitamins from the foods we eat, or from dietary supplements. Vitamins are essential for metabolism, growth, and physical well-being.
Why Do We Need Vitamins?
To put it plainly, if we did not consume adequate amounts of vitamins our bodies would not be able to function properly. Vitamins are essential to so many processes within the body that it would be very difficult for me to tell you all of the things vitamins are needed for. The fundamentals of cells depend greatly upon vitamins. Vitamins are responsible for keeping cells strong, binding tissues, fighting infections, etc. Without vitamins our cells would not function properly and thus our organs would suffer and eventually we would no longer be able to survive. Vitamins help regulate metabolism, help convert fat and carbohydrates into energy, and assist in forming bone and tissue.
Vitamin A works in our immunological systems strengthening membranes thus fighting infections, it works in our eyes aiding vision, it helps our ears by treating otosclerosis, it helps jawbone and tooth formation, healthy mouth membranes and gums, keeps our skin clear and keeps our reproductive systems healthy including fertility and sperm production.
The vitamin B complex is probably one of the most essential groups of vitamins to our health. There are twelve B vitamins: B1, B2, B3, B5, B6, B12, biotin, pantothenic acid, choline, folic acid, inositol, and PABA. These vitamins together are responsible for helping enzymes releas...

In 2011, the University Of Minnesota took women who take vitamins daily and studied them(Offit, Paul., 2013). The result was the same in that there was no supporting evidence that favors Pauling’s claims and statements. In conclusion, the general public believed the words of a man who had no specific evidence to support his own claims over researches done by trusted establishments who had evidence towards their own claims against Linus Pauling. Vitamin D is essential in many aspects especially during growth periods such as adolescents and infancy as indicated by Winston Koo and Nitin Walyat who are the respective authors of “Vitamin D and Skeletal Growth and Development”. Vitamin D is essential for the body as it helps development organ cells; without the development of organ cells, the body cannot fight against harsh diseases and it will eventually cause severe diseases which can lead to delayed growth rate(Koo, Winston ., 2013, p.188).. Children who drink breast milk are more prone to vitamin D deficiency because breast milk does not contain as many vitamins as mineral (Koo,
Vitamin C is a necessary vitamin for the body to carry out its functions properly. It is also known as ascorbic acid. It is a water-soluble nutrient that is found in some foods. It acts as an antioxidant in the body which helps to protect cells from the damage caused by free radicals, which are formed when our bodies convert the food we eat into energy. The body needs vitamin C to make collagen which is the protein required in wounds, healing. Moreover, vitamin C promotes the absorption of iron from fruits and vegetables and helps in promoting the immune system. Vitamin C is also important to protect our body from cardiovascular disease, prenatal health problems, eye disease, and skin wrinkling. We can obtain vitamin C from food and other sources.
According to Witney and Rolfes 2012, Vitamin C is a water-soluble vitamin that is necessary for normal growth and development. Water-soluble vitamins dissolve in water and leftover amounts of the vitamin leave the body through the urine. Hence the reasons why we need a continuous supply of this vitamin our diet. Vitamin C in humans must be ingested for survival. It is an electron donor, and this property accounts for all its known functions. As an electron donor, vitamin C is a potent water-soluble antioxidant in humans.

Vitamin A helps a lot in the maintenance of a healthy skin, mucus membrane, teeth and other soft tissues of the body.
Mary Wollstonecraft Shelley was born in Somers Town on August 30th of 1797 in London, England. Shortly after her birth her mother died due to puerperal fever, leaving her father William Goodwin to care for her and her three year old half-sister Fanny Imlay. Elanor Ty said, “Mary became his favorite child. He called her “pretty little Mary” and relished evidence of her superiority over Fanny.” At the age of seventeen Mary had her first relationship with a man known as Percy Bysshe Shelley who later became her husband. On a cold stormy night in 1816 Percy and Mary spent their time reading about ghost stories and which later prompted Mary to write her first sketch of what is known as today as Frankenstein or The Modern Prometheus.
Vitamin C is an essential in the body's defenses against infection. Susceptible children will not tolerate relatively unimportant infections and this can lead to prolonged illness and in the case of behaviorally disturbed children of symptoms previously well managed. Vitamin C is an extremely safe substance which is immensely beneficial to the brain and body in a multitude of ways. Its potential for preventing and treating autism has barely been touched. Vitamin C is heavily concentrated in the brain, but its exact role in brain function has not been fully understood. A recent search turned up 400 references referring to vitamin C and the effects of the brain, but the mystery still remains.
Mary Shelley was born 1797 in London, to her influential father William Godwin, and her mother Mary Wollstonecraft who died giving birth to her. Growing up Mary was educated and tutored by her father, and because of his reputation she was surrounded by intellectuals during the Industrial Revolution. At the age of sixteen, Mary ran away to live with her future husband Percy Shelley, a free thinker that her father did not approve of. Her marriage with Percy ultimately leads to turmoil in Shelly’s relationship with her father. Mary spent the summer of 1816 in a Geneva with her husband Percy, Lord Byron, and John Polidori. The group decided to write a ghost story which eventually led to Mary Shelly’s novel Frankenstein: The modern Prometheus. The novel would be defined a...
Thesis statement: Risks of texting while driving over the past few years has become a key topic for many Americans through the country. It has been the cause of numerous deaths and injuries and remains a vast disturbance for drivers. Hence driving is one of the greatest common causes of misfortunes on roads. This can result in, physical visual and cognitive distraction and significantly increases the amount of time a driver devotes not looking at the road. Therefore police officers should seize the phones of those who text and drive.
Vitamin, any of the organic compounds required by the body in small amounts for metabolism, to protect health, and for proper growth in children. Vitamins also assist in the formation of hormones, blood cells, nervous-system chemicals, and genetic material. The various vitamins are not chemically related, and most differ in their physiological actions. They generally act as catalysts, combining with proteins to create metabolically active enzymes that in turn produce hundreds of important chemical reactions throughout the body. Without vitamins, many of these reactions would slow down or cease. The intricate ways in which vitamins act on the body, however, are still far from clear.
Texting while driving is a widespread epidemic in the United States that has unfavorable effects on our society.“Driving while texting is the standard wording used for traffic violations” (Bernstein). It causes many people to be distracted which can lead to accidents. “Eighty-nine percent of people own a cell phone” (Gardner). That is a plethora of people that are at risk of texting while driving. Also, texting has increased by ten times in three years(Bernstein). “The risk of a crash for those who are texting is twenty-three point two times greater than those who are not” (Gardner).Driving drunk only makes a person seven times more likely to be in a crash (Bernstein). This means texting while driving is three times more dangerous than driving intoxicated. One in five drivers admits to texting while driving(Gardner). This shows that that texting while driving is a widespread epidemic. When a survey asked teenagers whether they text and drive,“seventy five percent of teens admitted to texting while driving” (7).Distracted driving causes seventy-eight percent of car crashes(Bernstein). “No distraction causes as high of a risk of an accident as texting while driving” (Gardner). Also with these statistics, it is not hard to understand why accidents in teenagers that are driving have risen. The Bluetooth capability in cars gives a driver a hands-free way to talk on the phone, but is still not completely safe (8). Also, only 1 out of 3 US cars sold in 2009 had this feature. New systems are being developed that will use Bluetooth as well a global positioning technology to allow parents to monitor cell phone use and texting while driving (10).
Vitamin B-12 is essential for energy production as well as influencing the way your body uses carbohydrates.
Walt Whitman was a man that served as a nurse helping wounded soldiers in the Civil War. While he was there, he took what he saw and wrote them in his poems. Every aspect of each poem related to the time that he was in and he wrote about every experience and feeling he had about what he saw. Whitman had three themes that he used to focus all of his poems on and these themes were individuality, democracy, and freedom. With writing with these themes, Whitman could make an impact on what the reader imagined in their head while reading and he was also able to convey a certain feeling through his poems that he wanted the reader to feel. Whitman had a unique style of writing, which was free verse. Through free verse, Whitman could direct and write a poem in a way that he liked and in a way where he was able to give more detail rather than writing in a rhythmic way. Through Walt Whitman’s themes of individuality, democracy, and freedom, Whitman was able to express his feelings about war and leaders in the poems that he wrote during the Civil War time.
Mary Wollstonecraft Shelley was born in 1791 in London. She is the daughter of Mary Wollstonecraft and William Goodwin. Wollstonecraft was a radical feminist writer, and Goodwin was a writer as well as a philosopher. It was said that this couple's combined intellect was dangerous to society; however, days after Mary's birth, Wollstonecraft died due to complications from the pregnancy. Mary spent a lot of time visiting her mother's grave when she was growing up. Her father taught her how to spell her mother's name by having her trace the letters on the headstone with her fingers, an interesting yet morbid way to teach a seven year old how to spell. Goodwin raised Mary by himself for the early part of her life. When Mary was four, he married Mary Jane Clairmont, who also had children from a previous marriage. Mary never fully accepted the stepfamily; she always felt like an outsider. Many of her feelings of loneliness and longing to know her mother are issues that are prevalent in the novel Frankenstein. These issues are analogous to the search that the monster had for his creator.
