Taste,enjoyment, culture, environment, social reasons, and popular trends. 2. Discuss examples of at least three of the factors identified in question 1. Taste is considered the number one factor when it comes to choosing foods. Foods that are salty and sweet are among the top choices. Culture plays an important role in choosing food. Foods that are easily available to a group of the population are more likely to be eaten over foods that are rare to the location. Someone from China may have different choices than someone from Italy. Social trends also have a role to play in choosing food. What family and friends eat and foods considered popular may be chosen over other foods, despite health concerns. **Make sure to read â€Å"The Take-Home Message† for this section (Pg. 7) What is Nutrition? 1. Explain how the focus of the study of nutrition has changed over time. Nutrition began a few hundred years ago as a science relating nutrients to diseases and its affects, but today is used as a way to promote good health and long life by healthy eating. ​** Make sure to read â€Å"The Take-Home Message† for this section (Pg. 9) What are Nutrients? 1. List the six categories of nutrients found in foods and in the body. Carbohydrates, Lipids (fats), Proteins, Vitamins, Minerals, and Water 2. Which nutrients provide energy? Carbohydrates, lipids, and proteins. Alcohol also provides energy but is not considered a nutrient. 3. When we use the term â€Å"calorie† to describe the energy content of food, are we actually referring to the word â€Å"calorie† or are we referring to the word â€Å"kilocalorie†? Explain. Kilocalorie, not calorie, is the correct term when referring to the energy content of food. Calorie is a much smaller unit of measurement. 4. How many kilocalories are provided in a gram of carbohydrate? Protein? Fats? Carbohydrates and Proteins have 4 kilocalories and Lipids or fats have 9 kilocalories. **Make sure to read â€Å"The Take-Home Message† for this section (Pg. 13) What Are the Primary Roles of the Individual Nutrients? 1. For each of the 6 classes of nutrients, briefly describe their primary role in the body. Use the table below to guide you. Macronutrients include carbohydrates, proteins, fats and water. Carbohydrates are the body’s Mai’s source of energy. Proteins provide the building blocks, or amino acids, for tissue in the body. Fats are also a source of energy but in a more concentrated form. Water makes up a majority of the fluids in the body, as well as its tissues. Micronutrients include vitamins and minerals. Vitamins help regulate metabolism and use other nutrients, while minerals assist in body processes. 2. List some food sources for carbohydrates, lipids and proteins. Carbohydrates include bread, cereals and nuts. Lipids include butter and oils. Proteins include meat and dairy. 3. Classify the vitamins according to whether they are water soluble or fat soluble. Water soluble vitamins include vitamin C and the 8 B-complex vitamins. Fat soluble vitamins include A, D, E, and vitamin K. 4. Give examples of major minerals and trace minerals. Major minerals include calcium and magnesium, while Trace minerals include iron and zinc. **Make sure to read â€Å"The Take-Home Message† for this section (Pg. 16) What is Credible Nutrition Research? 1. What are some questions you can ask yourself to evaluate the credibility of published nutrition information (in print or on the internet)? Was the research findings published in a peer-reviewed journal? Was the study done on animals or humans? Is this the first time I have heard this? Do the study participants resemble me? 2. Describe the steps of the scientific method. Scientists observe the natural world, ask questions, and put forth or submit an explanation, called a hypothesis, bases on what they observed. Next they test this hypothesis to determine if it is correct or not. After testing or conducting an experiment, it can be determined if the hypothesis is supported or not by the findings. If supported, the findings can be published. If not supported, the scientist then must revise or redo the hypothesis. 3. Why is a double-blind placebo-controlled study considered the â€Å"gold standard† of research? This study is the gold standard because all variables are the same and controlled for the groups with no bias toward any group or researcher. 4. How does sample size affect the credibility of research results? The sample sizes must be large enough so that any differences in the study are related to treatment and not just chance. **Make sure to read â€Å"The Take-Home Message† for this section (Pg. 21) What Is Nutrition Assessment and What Does It Involve? 1. Briefly describe the different methods for assessing the nutrition status of individuals. Which one is the â€Å"best† method? Explain your reasoning. Anthropometric data is used to determine body size or composition. Data gathered is compared to reference standards, which can help determine risk factors for developing disease. Biochemical tests assess nutrient levels in body fluids, how fast nutrients are excreted through urine, and metabolic by products of nutrients found in urine. Clinical tests inspect the body for over or under nutrition by inspecting hair, nails and lips. Dietary intake can be measured by interviews and questionnaires to reveal lifestyle habits. The most important of the four would be anthropometric due to its ability to evaluate for disease such as diabetes. **Make sure to read â€Å"The Take-Home Message† for this section (Pg. 27) How Do We Assess the Nutritional Status of a Population Group? 1. How are nutritional assessment methods for a population group different than those which would be used for an individual?

Sililoquy :: essays papers

Sililoquy I went to work as any other day, walking around the mall with my best friend, staring, gazing into every transparent glass containing items for my wish list, leaving me with â€Å"wants†, yet will never become possessions. My phone rang, as my mother, carefully, yet failing to hide her tears, told me my cousin (Joshua), two years of age, had drowned. I felt your struggle I thought you had encountered. The splash of water, as it skillfully entered your windpipes, devouring your lungs until your eyes became bloodshot red, as you gasped for that last breath of air, only to swallow more water. And then, slowly your heart stops beating as your body swam along, allowing the current to be your guide. Your body drifted down the canal, but your soul drifted towards heaven. I held my uncle close, my shoulder accepting his tears and cries unheard for his beloved son. Nothing, no pain can ever compare to the injection of a lost loved one I was given when I hugged him, as I felt every breath of sorrow moisten my chest. His firm grip on my shirt held me without a thought of letting go, as he shed his tears on me, seeping through me shirt, my pores, through my soul and directly to my heart. The sharp pain causing your breaths to shorten and uncontrollable tears to fall with no bottom to reach. I heard his unheard cries for his son. That was a want that could never be fulfilled. That was a missing piece that could never be found. A child, every child, is certainly a gift from God. The creation of every human being, the growth, the heart, the mind; never knowing the capabilities it will endow. Never knowing the fullest extent of it’s imagination, enabling them to do anything, and everything it desires; and to take effect into my life is truly one of the many mysterious ways God has worked, in my life, and everyone’s life. Joshua, two years into this earth and yet I feel he has accomplished more than a man, yet no less than an angel. How can such a tragedy being so many joys into one’s mind; one’s life? And not just one life, but many lives.

Importance of Life

Lofe is imprtantBecause it is your one chance to do anything. You can use The meaning of life is to take care of our planet. To be hard working and serve God. To help out in fixing communities – that's what life is about; you should not live only for fun but help others enjoy life too. A humanist would say we each make our own meaning by the way we live. The meaning is whatever meaning/purpose you care to assign to it†¦ or none at all. If you have a religion, you could find meaning there; a particular philosophy, ditto. If you're a nihilist, you might conclude that there is no meaning at all.To understand the meaning of life we have to turn to the source, or creator. If you believe in such things, God. If he put us here, it was for a purpose. So He may be the only one able to provide us with the answer. Some people will acknowledge that everything we need to know about the purpose of life and about God himself is found in one book, the Bible. If you believe in the Bible, the meaning of life is in God's inspired words: â€Å"If anyone would come after me, he must deny himself and take up his cross daily and follow me.For whoever wants to save his life will lose it, but whoever loses his life for me will save it. † Luke 9:23. Ecclesiastes 12:13 â€Å"Fear God and obey His commandments for this is the whole duty of man. â€Å"The irony in life these days is that, in order to find it's meaning, you merely have to Google it. To tell you the truth, I don't think anyone knows the true meaning of life. People say that the only way to know the true meaning of life is to live a full life with many near death experiences, then God tells you an instant after you have died.If you have a complex enough mind, and when God wants us to know, he will tell someone after they die and let that person be revived to tell the rest of the human race. If that never happens then we will just have to live life with many questions and as best we can. That's what God wa nts us to do. That's one way to look at it. The meaning of life is to utilize our main driving force, curiosity, without which none of us would even exist. Discover and find out new things. Space travel, for example, will lead to great new discoveries – including life near and far from us.The meaning of life is that we exist, that we are products of a force called creation, and that we should all support and affiliate with that force in every one of it's manifestations. The difference between life and the inanimate is that life has consciousness. The Serenity Prayer: God, grant me the serenity to accept the things I cannot change, courage to change the things I can, and wisdom to know the difference. Any Christian should know the purpose of life is simple: to serve God. Any Christian who doesn't know this needs to build up their relationship with God; He'll show you all you need to know.You're born, you breed, you die. Therefore the only meaning is to keep the species alive, all the other stuff is just to make it interesting. No one really knows the answer to this. Philosophers and religionists have been debating it for thousands of years. Life's meaning is what it means to you! What do you value in your life? Everyone has there own meaning and there own perception of life. Britannica says it's the sequence of physical and mental you body and go to amazing places and see amazing things.Life is a once in a lifetime thing so if you don't enjoy it then you will have wasted the most brilliant thing on earth. Dictionary. com states the meaning of life is: â€Å"The property or quality that distinguishes living organisms from dead organisms and inanimate matter, manifested in functions such as metabolism, growth, reproduction, and response to stimuli or adaptation to the environment originating from within the organism. â€Å"I believe it's the beauty of God's creation. The meaning of life is to make life meaningful.

The Health And Natural Food Stores - 2082 Words

The health and natural food stores have become increasingly noticeable with the modern diet crazes in The United States. The health and food industry extends beyond the GNC s store, health consciousness also extends to the local grocery store. In the featured writing the following will be explained, the segmentation of local market, a developed strategy for attracting a target audience chosen, a developed strategy for building long term customer loyalty, a discussion on reasons for using strategies, furthermore a list of three potential methods of measuring customer satisfaction and loyalty. Last a message for attracting the target audience. The topics discussed are ultimately going to be used for a new health food store called Phil’s†¦show more content†¦A strategy for targeting an audience is one of looking for families and individuals with disposable income and care for their wellbeing. Purchasing food items that provide important nutrients like potassium, dietary fiber, vitamin D and calcium, could add up to $380 annually to consumers’ grocery bills(Gustafson, n.d.) Americans have seen the value of foods with preservatives in them and notice they can purchase unhealthy classified items at a lower cost and shorter preparation time in contrast to a fresh cooked meal that inherently takes hours to prepare. The diet of an American differs from developing countries and others, the food in the US contains preservatives that are cause for long term health problems. The goal of Phil’s Organics is not to frighten or terrify a customer into making healthier food choice but rather giving the customer the informed alternative, with an emphasis of little advertising exposure, again to gain the customers trust and do its part to reverse obesity trends in the US. Natural, organic and eco-friendly products’ consumers have been divided into 7 shopper segments based on demographics, their lifestyle, organic purchasing history, attitudes toward organic and natural products, etc. * True Believers : These consumers want above all to keep an healthy body. They are convinced of the benefits of organic and natural products for them, their their daily lives and the environment. They like to try
