Being a Nutritionist Essay

What is a nutritionist? A nutritionist is an health practitioner who works with a person’s diet to help heal or prevent disease. A doctor who calls himself/herself a nutritionist may have several different levels of education. They could have a degree in Nutrition or Dietetics from a University or certification in Nutrition Education or Counseling from a professional training school. Most people who have a degree in Dietetics in the United States will be registered with the national board and will call themselves Registered Dieticians or R.D.’s. These professionals have a slightly different perspective from the more holistically oriented Certified Nutrition Educators or Counselors also called C.N.E’s and C.N.C’s. While a nutritionist may have a vast scientific knowledge of the body and nutrition, they are often quite strict in their approach to patient care. Their focus is entirely within the focus of western medicine, meaning they have guidelines when it comes to dietary recommendations. They often work directly with medical doctors or in hospitals. In many ways, they are trained to treat the disease rather than the person as a whole. They might help a patient by helping them make a diet plan, or even suggesting them to other kinds of doctors that can help the patient recover or prevent an illness. For example, the reason the patient is not getting many nutrients since he/she doesn’t eat much food could be because of stress or not getting enough sleep; therefore, the nutritionist would send the patient to the sleep holistic doctor, or a stress management program or professional. One important fact that makes nutritionist so important is that they link the patient with many other doctors that could help them. They help make the connection between proper diet and a good holistic health. They can make the link on how eating the right food can either prevent a disease or even treat a disease. They are the experts in the area of food, nutrients, and vitamins. It is imperative that once a patient faces a problem with diet, he/she must visit a nutritionist. Since most health problems are linked to some kind of factor, nutritionists are connected to other kinds of doctors, such as social coordinators and sleep holistic doctors. Nutritionists are important in the field of disease treatment and prevention. Visiting a nutritionist can increase better knowledge on one’s diet and what they should eat more. Finally, they are the kind of doctors that can change one’s life.

Racist Speech

As a society, we need to realize that with honesty, you have a certain responsibility and walk a fine line between offending people and possibly making racial statements. Therefore, the main difference between my interpretation and the conventional one is my focus is on unintentional vs.. Intentional racist speech. The Balance between racist speech and expression in a college environment can be difficult to decipher; students are encouraged and should express themselves while n campus, this embraces their creativity, passion, talent and allows them to feel Like they're in a safe environment.However, there is a fine line between expressing themselves in an offensive way vs.. An effective way. The article written by Derek Book titled Protecting Freedom of Expression on the Campus focuses on a situation that occurred at Harvard, stating that â€Å"Two students hung Confederate flags in public view, upsetting students who equate the Confederacy with slavery'. According to my deflation t his Is clearly racist speech and started quite the commotion among the Taft at the prestigious university and caused some other colleges to take racist speech too new level.In Books article his statement of colleges â€Å"some have enacted codes to protect their communities from forms of speech that are deemed to be insensitive to the feelings of other groups. † Even the words â€Å"Insensitive to the feelings of other groups† degrades the first amendment and could lead to racism. While some colleges chose not to enforce any restrictions, others varied In their approach and seventy of retribution.There are many ways to deal with this issue but the fact that each institution deals with it differently proves that racist speech continues and the answer remains elusive. Even though communities have the right to regulate speech they must do so very cautiously. If they do, they must apply the rules and limitations across the board and cannot enforce selectively to prohibit c ertain kind of messages and allow others that they think are acceptable; which can again be portrayed as racist speech.He goes on to say that â€Å"I am sure that the vast majority of Harvard students believe hat hanging a Confederate flag in public view-or displaying a swastika in response-is insensitive and unwise because any satisfaction It gives to the students who display these symbols Is far outweighed by the discomfort It causes to many others. † When freedom of speech does not guarantee that the choice made by the student's will be the same choice Book would make. Right after that quote, Book states â€Å"l share this view', but we forget that the flag symbolizing slavery was not the intent but rather an unintentional form of racist speech.If you are an agency of the government including public universities the free speech clause in the first amendment will be upheld even if the event offends the feelings or believes of that community. Book says in his article  "l have difficulty understanding why a university such as Harvard should have less free speech than the surrounding society- or than a public university'. In response Harvard is a private university which means it is not obligated to all government rules and regulation, the problem comes from the ambiguous limitations of the first amendment.Who's to say what is offensive or not in the eyes of the law, there are no tangible words for racist speech which results in many different interpretations. Colleges are not the only institutions with this problem; racist speech can be found everywhere. Even President Barack Obama is trying to end discrimination regarding the military and people who have different sexual preferences. The controversial â€Å"don't ask, don't tell†, passed in 1993, prevents gay men and lesbians from revealing their sexual orientation, and prevents the military from asking about it.This discuss policy has been in effect for over 15 years, and it's been suppor ted by our military at all levels. However, this law of the â€Å"don't ask, don't tell† policy is unconstitutional because the main purpose of the First Amendment is freedom of speech, if lesbians and gay men are not allowed to have this right in the military; then the military and congress who approved this law are both racist. This is an example of racist speech and our government is acting as if it were a private institution and not part of a government that is owned by the people.President Barack Obama wants to put an end to the anti-gay policy because it clearly sends a message of discrimination regarding the right to freedom of speech. It is a battle between our right to freedom of speech and the Military right to pass a law only because it can. Although these incidents seem quite manageable they can easily become a much bigger problem. For instance what if someone decides to burn the offensive flag at Harvard down, we now have crossed the freedom of speech line and ha ve committed an illegal act.Can you imagine what would happen in our public schools if we tried to enforce â€Å"don't ask, don't tell†. Speech can cross over to action which causes racial tension but is also considered a crime. If you minimize racist speech you put a spotlight on racism only making the situation worse igniting the flames that started the problem in the first place. Book says â€Å"it would be better to ignore† however ignoring the problem is a Band-Aid not a solution. In order to come to a universal agreement that will end racism, means making it a priority to our first amendment.Book says â€Å"The fact that speech is protected by the tuition from Harvard the students who felt offended by the flag that symbolized slavery through their eyes, would strongly disagree with Book protesting that it is our right. However our leaders in congress seem to strongly agree, by their actions of standing by â€Å"Don't ask Don't Tell†, they must believe gay men and lesbians do not have the right to voice talk or congregate with others of their persuasion while in the service of our government about their sexual preference. As long as there is freedom of speech, it is considered wrong to tell someone what they can or can't say.

Sleep Deprivation in Teens - Free Essay Example

Sample details Pages: 2 Words: 596 Downloads: 9 Date added: 2019/07/29 Category Health Essay Level High school Tags: Sleep Deprivation Essay Did you like this example? You might be wondering what is sleep deprivation is. Sleep deprivation is basically not getting Enough sleep. So sleep deprivation is not a big problem for me, but for other people, it is a big problem. Don’t waste time! Our writers will create an original "Sleep Deprivation in Teens" essay for you Create order Experts are calling it a National Health Crisis. So if experts are calling it National Health crisis, why are we not doing something about it? If we did something about it wouldnt it solve most of the problems in the school system? Am I the only one who thinks that. It also as a greater increase in anxiety in 9 out of 12 people. So if anxiety makes people panic, right? So if getting more sleep would make people panic less, which in turn would make it so teens would do better on a test. Which bring us to our next topic. America’s grades racking in the world. Firstly, without any sleep, you are at higher risk of getting many health problems. Such as high blood pressure, heart disease, obesity, and diabetes. Sleep is important for overall health, and inadequate sleep is associated with numerous health problems. And is some rare cases death. How cannot getting effect sleep can cause death. Also can cause Hormonal imbalances, illnesses, hallucination, disorientation, moodiness. Who could have thought you not getting enough sleep could do all this. Sleep has a direct correlation with America’s grades racking in the world. Maybe that is why were so low in the ranking. If students like me could more sleep maybe we could do better on tests and other things. This is very Apparent and college students. People think its all your phones falt, but its also because of school. Staying up so we study for tests, is another reason for sleep deprivation. I mathematics Americas lowest Average out of all of Americas averages. The middle average of America is science. and the highest average in America is reading. Maybe if we gay kids must sleep, maybe more kids to get into Ivy League colleges like brown Harvard or Yale. So most teens must head to school before theyve gotten the 8.5 to 9.5 hours of sleep recommended by the American Academy of Pediatrics (AAP). So if research and Common sense tell you that sleep helps the grades why dont professionals and experts do something about it. I dont know why They dont do something about it they just dont. In 1965, 17-year-old high school student, Randy Garder stayed awake for 264 hours. That’s 11 days to see how he’d cope without sleep. On the of his test, his eyes stopped focusing. Next, he lost the ability to identify objects by touch. By day three, Gardner was moody and uncoordinated. At the end of the test, he was struggling to concentrate, had problems with his short-term memory, became paranoid, and started hallucinating. Although Gardner recovered without long-term psychological or physical damage, for other losing shuteye can result in hormonal imbalance, illness, in extreme cases, death. We’re only beginning to understand why we sleep, to begin with, but we do know it’s essential. Adults need seven to eight hours of sleep a night, and adolescents need about ten. We grow sleepy due to signals from our body telling our brain we are tired, and signals from the environment telling us it’s dark outside. The rise in sleep-inducing chemicals, like adenosine and melatonin, send us into a flight doze that grows deeper, making our breathing and heart rate slow down and our muscles relax. This non-REM sleep is when DNA repaired and our bodies replenish themselves for the day ahead.
