Nutritional Science Essay

Shani Pinckney Mr. Jackson Biology 10 -31-12 My purpose on writing this paper is to inform you about Nutritional Science that pertains to health performance, metabolism, and effects on disease process. Health performance is the ability of sciences that go on within your body, health performance ties to nutritional science because a physiological response of the body is to diet.

With advances in the fields of molecular biology, biochemistry, nutritional immunology, molecular medicine and genetics, the study of nutrition is increasingly concerned with metabolism and metabolic pathways: the sequences of biochemical steps through which substances in living things change from one form to another. Metabolism is the life-sustaining chemical activity in which a series of processes like food is converted into the energy and products needed to sustain life. My chief reason on researching this topic is to let you know about YOUR life and the sciences that go on within your body, and how to manage this.

I plan to approach this topic by researching, studying, looking at actual data, school reviews, class reviews and looking up information on the internet, and also books. Nutritional science is a factual study. It can be a taken as a major at certain schools. It can also be a problem because many people don’t know how to address the fact of nutritional science or what it really means. The major points in my essay are health performance, metabolism, and effects on disease process. People should read my paper because nobody knows you like you.Everyone wants to be healthy or be fit or be desirable to one’s image but no one knows exactly where to start. You should read my paper because it deals with YOUR life, YOUR body, and YOUR wellness in life and the sciences that go on within YOUR body.

The human body contains chemical compounds, such as water, carbohydrates ; sugar starch, and fiber/ amino acids ; in proteins, / fatty acids ; in lipid , / and nucleic acids ; DNA and RNA. All of these chemical compounds occur in all types of forms and combinations: hormones, vitamins, and phospholipids both in the human body and in the plant and animal organisms that humans eat.These are my arguments to support my thesis statement. There are six major classes of nutrients: carbohydrates, fats, minerals, protein, vitamins, and water. Carbohydrates are the body’s main source of energy and should be the major part of total daily intake.

Fat supplies energy and transports nutrients. Minerals are vital to our existence because they are the building blocks that make up muscles, tissues, and bones. They also are important components of many life-supporting systems, such as hormones, oxygen transport, and enzyme systems.Protein supplies amino acids to build and maintain healthy body tissue. There are 20 amino acids considered essential because the body must have all of them in the right amounts to function properly. Twelve of these are manufactured in the body but the other eight amino acids must be provided by the diet.

Vitamins are organic substances present in food and required by the body in a small amount for regulation of metabolism and maintenance of normal growth and functioning. Last but not least water, water helps to regulate body temperature, transports nutrients to cells, and rids the body of waste materials.
