...Reflections on Nutrition SCI/241 4/4/2011 Summer Groff Week 9 Checkpoint Reflecting on what I have studied so far on nutrition, using my assignments completed up until this point is that I have come to the knowledge of how the human body works from the moment food enters the mouth through digestion and coming out as waste. I have also obtained knowledge about how the body changes through aging, and how diet and exercise can actually help the body’s digestion and growth process. I have learned through doing research throughout my course on nutrition, which has helped me gained understanding on what to do to stay healthy as I age. The assignment that I enjoyed throughout this class is the three day activity analysis. After completing the analysis I became aware of what I was eating and made me aware that food is the body’s main source of fuel, which means that nutrients in food gives the body cells energy to function. I am now cautious and made changes of what I eat. Making healthy decisions and adding daily exercise to my life style has improved my health. Another assignment I enjoyed was week 5 on dehydration. I learned much about the importance of water and how the body needs water to function adequately. Water washes away and cleanse out toxins, it also assists the cell functioning, and is the primary aid of the ear, nose and throat functioning. Water also bathes the cells in the body and serves as a lubricant; it cleanses both external and internal surface...

...The Human Digestive System Human Digestive SCI/241 Nutrition November 22, 2012 Mr. Brain Oddi By: Lenicia Ridley The Human Digestive System Human Digestion 1. How long does it take for food to go through the digestive system? Salivary glands begin the digestive process at the sight and smell of food. After, food enter the mouth and is moistened by, saliva and chewed by the teeth, it transforms into a bolus. Once the bolus leaves the mouth, it moves into the pharynx where it can be swallowed. The bolus then moves from the pharynx into the esophagus, which connects the pharynx to the stomach. Once the bolus reaches the stomach, it is mixed with acid secretions to transform the bolus into chime, a semiliquid food mass. Food is partially digested into the stomach, and chime usually empties from the stomach in 2 to 6 hours. This timeframe is determined by the size and type of meal ingested. 2. How does digestion occur...

...Understanding Your Fats and Fiber Lori Siegele SCI/241 Nutrition May 23, 2013 Denice Mittelstaedt Understanding Your Fats and Fiber Understanding Your Fats and Fibers Lori Siegele May 23, 2013 SCI/241 Nutrition Denice Mettelsteadt According to “Face the Fats” the bad fats are the saturated and the Trans fats, better fats are the monsaturates and the polyunsaturated fats, and the best facts are the omega-3s. (B, 2012). There have been so many illness that are blamed on fats, I don’t think there is one out there that hasn’t been, from heart disease to cancer. The bad fats have got to be limited and when you are putting them in your body you want to make sure that you are staying with the low percent. The good fats you want to make sure that you are staying on the higher percent. So in other words the bad fats have got to be 5 % and lower and the better/best fats need to be 20 % and higher. A Saturated fat is known as a fat that is a type of single-bond animal or vegetable fat. (These are mostly found in butter, meat, egg yolks, and coconut or palm oil) it is known to increase the cholesterol level in the blood. A fat having a chain of unsaturated fatty acid is known as a unsaturated fat. Trans-fatty acids are known as an unsaturated fatty acid formed by partial hydrogenation of vegetable oil that is also believed to raise the blood cholesterol levels in the body. The differences in the stability between saturated and unsaturated fats are known as hydrogenated...

...Dehydration XXXXXXXX Axia College of University of Phoenix Dehydration Water is a major component of blood, helps to lubricate joints, and allows electrolytes to power nerve responses. Grosvenor and Smolin wrote in Nutrition: Everyday choices (2006) that the average person’s body is 60% water weight, and keeping enough water in the body is a continuing task for everyone. The loss of one to two, up to four or more liters of water each day in sweat alone is an indicator of how important consuming enough water is. (Grosvenor & Smolin, 2006). By examining the functions of water and what can happen when the body does not receive enough of it, this essay will outline the important role water plays in keeping humans alive and healthy. Of the many essential nutrients humans consume to sustain their healthy lives water is by far consumed in larger quantities and with more urgency. (Grosvenor & Smolin, 2006). So much water is needed to power the body that even though 90% of water is reabsorbed during digestion Grosvenor and Smolin (2006) cite the Institute of Medicine, Food and Nutrition Board’s recommendation for water intake: 2.7 liters for females and 3.7 liters for males, every day. Grosvenor & Smolin go on to inform that one of the main ways the body loses much of this water is through the elimination of excess vitamins, minerals and waste products. The more of these particles one’s body has to expel, the more water it needs to eliminate them. This elimination...

...The sight and smell of food begins the digestion process with the salivary glands. Once food enters the mouth it is moistened by the saliva and grounded down by the teeth. The food transforms into a bolus. The bolus leaves the mouth and moves into the pharynx, where it is swallowed. The bolus moves from the pharynx to the esophagus, which moves the food to the stomach (University of Phoenix and Axia College, n.d.). The stomach is an organ in the digestive tract that mixes food and secretes gastric juices. Once the bolus reaches the stomach, it mixes with the acid secretions to transform into chime, a semi liquid food mass. Food is partially digested in the stomach, and chime empties from the stomach in two to six hours, depending on the size and type of meal ingested (University of Phoenix and Axia College, n.d.). After chime leaves the stomach it enters into the small intestine, which is divided into three parts known as the duodenum, the jejunum, and the ileum. Here the majority of digestion and absorption of nutrients from food takes place. Once food is in the small intestine, bile from the liver and gallbladder help with the digestion and absorption of fat, while enzymes and bicarbonate from the pancreas aid in the digestive process (University of Phoenix and Axia College, n.d.). Materials not absorbed in the small intestine enter the large intestine through the sphincter. The sphincter keeps material from the large intestine from re-entering the small intestine...

...Checkpoint Protein Article Search Nutrition SCI/241 Professor Zachary Lahlou July 16, 2012 The article I reviewed was “Does Milk Hurt Kids” written by Mary Carmichael for Newsweek magazine in 2006. The article relates to the protein needs of infants or toddlers compared to adults. The author believes that American children are not getting the proper nutrition because so many parents are substituting rice or soy milk which lack needed vitamins. This article was very informative and clearly explained that while soy and rice milk have good benefits for adults it can cause serious health conditions for infants and children. These products lack the proper amount of vitamin D and protein needed for good development. As noted by the Center for Disease Control (CDC), lack of proper vitamins and nutrition can result in rickets (a severe vitamin D deficiency) and kwashiorkor (protein deficiency) which are normally only found in third world countries. The reason why rice and soy milk cause issues for younger children is because their diets do not contain a wide variety of foods and so they lack vitally needed protein and vitamins. Adults eat such a wide variety of foods that substituting rice or soymilk for dairy milk does not typically have any affect on the amount of vitamins and protein consumed. According to Albert Yan, “a pediatric dermatologist at the University of Pennsylvania, babies' skin becomes like "flaky paint"...

...Amino Acids and How They Relate to Athletics SCI/241~Nutrition July 8, 2010 Amino acids serve in many different ways in an athlete body. Typically amino acids were prescribed many years ago known as a “branched-chain amino acids (BCAA)” (Weider, 2003), characterized as supplement for body building. Muscles are generally made up of amino acids, athletes are encouraged to supplement with the loss. Another characteristic of BCAA is to generate energy. Amino acids taken before a workout will strengthen the athlete muscles. The intake of protein is encouraged before a workout also. Boost in the brain of an athlete mental capacity is consumed with the amino acids before a work out. However, an athlete must mentally stable their mind to do a tedious workout. Your immune system must functions at a healthy status at all times, in order to be an athlete. This is why amino acids help promote the building of a strong immune system. Sometimes the lack of a nutrient in the body can have an effect on the brain. Taking precautions is recommended to insure that supplemental intake of BCAA may not cause any problems to the brain; one should consult a physician before taking BCAA.

...Capstone: reflections on Nutrition Michelle A. Lilley SCI/241 May 25, 2011 Mike Esposito Capstone: reflections on Nutrition This class has been very enlightening for me and I have truly enjoyed it, but I think that the assignment I liked most was the human digestion system in week two. This was very interesting to me to see exactly how this process works and all the different areas that we have that work as one for the digestion process to occur. I did try a new diet plan that USDA Food Guide Pyramid suggested and ate more different kinds of foods that were recommended out of my normal routine. I felt that it just was not for me. Although I did start eating more dark green vegetables and other types of vegetables that I normally would not eat because of the type of diet lifestyle I was on, and I feel it has made me feel better about myself that I am getting the nutrients that I need to be healthy. I started this in the week one assignment: Fundamentals of health and diet. This lesson also taught me the importance that introducing the different kinds of vegetables and foods to my diet was more healthful to me. I also learned this in week five: The impact of water, Vitamins and Minerals. I feel this week was the most useful to me and helped me understand the importance of water in our diets and the importance of vitamins and minerals to keep us healthy. Overall I truly enjoyed everything I learned in this class and hope to use all the tools for the rest...

...Dehydration Denise Crago Sci 241 October 3, 2010 Matthew Badtke Dehydration Dehydration is defined as a loss or insufficient levels of water and important blood salts like potassium and sodium in your body. Important organs like the kidneys, brain, and heart can not function properly without water and salt. Dehydration is most common in underdeveloped countries, were diseases like cholera and dysentery kill millions every year. Unfortunately infants and small children are the most likely victims. Still, if the right conditions are present like severe vomiting or diarrhea even those in modern countries like the U.S. can become dangerously dehydrated. Water is the single most important element in the world. It is the very basis for all life on Earth. As babies, water accounts 70 to 80% of our body mass. The older we get the more this percentage decreases, eventually balancing at approximately 60 to 65% for men and 50 to 60% for women. The most important organ in the body, our brain, consists of 80% water. The amount of adipose tissue in our bodies determines the natural percentage of this element. Women tend to have more of this fatty tissue thus decreasing the amount of water present. The chemical make up water, hydrogen and oxygen, are crucial to sustaining life because of the weak chemical bonds made with other molecules. This allows water to act as the primary solvent for many bodily functions like digestion. Water is also an incredibly efficient conductor of...

...Protein and the Body Robert Jacob SCI/241 NUTRITION March- seventh-2014 Dr. Nearor Protein and the Body Protein has six primary bodily functions. Protein is used to repair and maintain body tissue as well as your skin, hair, and eyes. It is also used as a major energy source for the body and is involved in the creation of some hormones. Protein increases the rate of chemical reactions in the body in the form of enzymes, and it aids in transportation of certain molecules like hemoglobin; which is a protein that transports oxygen throughout the body. Protein is also responsible for forming antibodies that help stop infection, illness and disease. The "Centers For Disease Control And Prevention" (n.d.) website lists the the two types of proteins as complete proteins; being the one that provides all of the essential amino acids, and incomplete proteins; sources that are low in one or more of the essential amino acids needed to form a complete protein. Complete proteins or high quality proteins are found in meat, poultry, fish, milk and eggs. Incomplete proteins can be found in rice and dry beans. But when consumed together, the rice and beans contain enough amino acids that the body needs. Amino acid content and the sequence of amino acids of a specific protein is determined by the sequence of the bases in the gene that encodes the specific protein. Within the amino acid sequences of proteins we can find the necessary information that will determine how the protein...

...Sci241 Final In: Science Sci241 Final SCI/241 FINAL Project Personalized Nutrition and Exercise Plan January 13, 2012 Ruby Warner In my family we have a lot of major health problems. The one health problem that most of my family members suffer from is High Blood Pressure. “Blood pressure is the force of blood against the walls of the arteries as the heart pumps blood throughout the body. Many factors affect blood pressure, causing it to change from day to day and throughout the day. We are unable to control some of the factors that increase the risk of developing high blood pressure like being African American, over the age of 35, family history of high blood pressure, or having diabetes, gout or kidney disease, but the good news is that there are some that we can change”!(mckinley.illinois.edu/handouts/blood_pressure_factors.html). In order to maintain a good blood pressure I should have an exercise plan that involves my cardiovascular, I need to exercise at least 2.5 hours a week. These exercises include cycling, walking, and swimming. Also I may want to talk with my doctor to make sure my body is healthy before I start my exercise program. Nutrition is very important in helping to control my blood pressure and helping with not getting this because I have a family history. The way I need to do this is eating well balanced meals. Here is a way to do this. “The DASH (Dietary Approaches to Stop Hypertension) eating plan is recommended if your blood pressure is high...

...SCI/241 Protein Article Research Proteins We all live active lifestyles for the most part depending on how much exercise we get or depending on the type of work we do. Just even walking or cleaning the house our bodies get damage done to them. Were kind of like a car and always needs repair even if we don’t think we do. In our part we eat to provide essentials to help our bodies do the repairs we need to and these foods contain one important thing we need and that’s protein. They can be good but too much or too little can have some impact on our body repairs. Proteins are basically building blocks called “Amino acids” which contain 20 or more essentials that come together to help repair the body’s damages. According to our text “proteins are essential to every cellular function” (Moore 166). These proteins come in essentials and non-essentials which the essentials are what the body cannot produce. The daily intake of proteins really determine on age and weight. For example a male my age and my weight needs 56 grams of protein a day. I weigh 150 pounds so someone who is like above 180 might need more protein to have repairs go smoothly. My son though is one and the recommended intake is 13 grams a day. Good sources of protein come from poultry, fish, nuts, and red meat. There are concerns though especially with protein intake which is whether you have to much or not enough. There is what is call protein deficiency and our text says “protein deficiency occurs when...

...Understanding Food Labels Jacqueline Allen SCI/241 February 7, 2013 Professor John Menez Abstract The purpose of this paper is to provide consumers with the knowledge they need to choose the right food to bring themselves to their healthiest level. Based on their lifestyle and medical issues they can get the right balance by using the 5/20 rule as well as the six key label facts to assist them in making good decision choices and getting the nutrients they need for overall good health. Understanding Food Labels The 5/20 rule is used to judge the value of nutrients that are needed or healthy and for those things in the foods that are not needed or not so healthy. 5 stands for 5% or lower of a nutrient is not enough and 5% of something that is not needed or unhealthy for example; fats, sugars, etc. is acceptable. The 20 in the 5/20 stands for 20% of a nutrient needed or healthy for example; vitamin C or Protein is acceptable at 20% or more however 20% of an unneeded or unhealthy nutrient is unacceptable. Using this rule allows consumers to make better and healthier choices about their eating habits. The nutrition labels are divided into these six key fact sections; Serving Size, Amount of Calories, Limit these Nutrients, Get enough of these Nutrients, Percent (%) Daily Value, and Footnote Daily Values. When reading a food label the amount of calories is figured per serving. If the bag or container lists the serving size as four then the calories shown on the label...

...Three Day Activity Analysis Tonya Spaulding SCI/241 September 2, 2011 Summer Dale Three Day Analysis Some of the everyday changes I would make to increase my energy levels into my everyday activities would be to exercise in the morning. I believe taking a walk or doing floor exercises would help increase my energy levels on a everyday basis. I believe that exercising and giving yourself a good workout in the morning or even before one goes to bed. Before one goes to bed it will help one sleep in the morning exercising will help give extra energy that is needed throughout the day. I think if one incorporates physical activity at least half of an hour to an hour in the morning helps one in many ways with increasing energy and overall maintaining a healthy lifestyle in general. There are days that I do not want to take walks and if that is the case I will do an alternative exercise. Some other activities like riding a bike, jogging in place, aerobics, sit ups, yard work, or spending a bit more time getting ready in the morning all of these activities will burn calories to help keep ones body healthy. There are some activities that can not be performed year round especially if one lives in parts of the United States were the winters are bad and...
