...Phoenix Nutritional Needs Nutrition is the major intrauterine environmental factor that alters expression of the fetal genome and may have lifelong consequences. This phenomenon, termed “fetal programming,” has led to the recent theory of “fetal origins of adult disease.” Namely, alterations in fetal nutrition and endocrine status may result in developmental adaptations that permanently change the structure, physiology, and metabolism of the offspring, thereby predisposing individuals to metabolic, endocrine, and cardiovascular diseases in adult life. Animal studies show that both maternal undernutrition and over nutrition reduce placental-fetal blood flows and stunt fetal growth. Impaired placental syntheses of nitric oxide (a major vasodilator and angiogenesis factor) and polyamines (key regulators of DNA and protein synthesis) may provide a unified explanation for intrauterine growth retardation in response to the 2 extremes of nutritional problems with the same pregnancy outcome. There is growing evidence that maternal nutritional status can alter the epigenetic state (stable alterations of gene expression through DNA methylation and histone modifications) of the fetal genome. This may provide a molecular mechanism for the impact of maternal nutrition on both fetal programming and genomic imprinting. Promoting optimal nutrition will not only ensure optimal fetal development, but will also reduce the risk of chronic diseases in adults. Maternal nutrition plays a critical role...

...Toni Mia Duran Bio 314- Nutrition Professor Sillanpaa October 16, 2013 The Differences There is lipid and proteins in many things we eat. One healthy example of a lipid would be grilled chicken. Chicken is a good source of protein when it is not soaked in olive oil and the extra fattening products that can be added. Grilling the chicken cuts back the intake of lipids. An unhealthy lipid would be a hamburger. Either way you get the hamburger meat whether you get the patties ready or make them yourselves, they are filled with grease. Unlike chicken, the grease stays in the hamburger patty. There are also healthy and unhealthy amino acids and proteins. Fish would be a good example of healthy protein. It is considered on of the best intakes for protein. It is not only good for that, but helps the brain too. An example for an unhealthy amino acid and protein would be maltodextrin. This is used is in artificial dietary fiber. It is made from corn and is very hard to digest. One thing it does do is make a person feel full for the meantime. As bad as it is, I like some fatty foods such as hamburgers. I do not eat them every day, but they are fast and easy. Chicken is very good as well. It is so easy to eat junk food. It is so convenient and so fast to either grab or even make at home. One thing I do not like AT ALL is fish, any of it.

...Gregory Smith Professor Virginia Uhley FNS 370 14 April 2014 The Vegan Diet: A Healthy Risk Consuming foods rich in nutrients is more likely to reduce the risk of degenerative diseases than taking a broad array of supplements for many reasons. Research has shown that people who eat more vegetables and fruits have lower risks of several diseases including heart disease, cancer, diabetes, and high blood pressure. Supplements cannot provide all of the nutrients of food. Although many of the same vitamins are provided, it is not proven that vitamins are solely responsible for reducing disease. Whole foods also contain many other naturally occurring substances that help protect you from many diseases. For example, grains provide essential fiber that prevents diabetes and heart disease (Mayo Clinic, 2013). Supplements containing too many individual nutrients can actually cause health problems due to toxicity and vitamin interactions. Since there is no significant data to suggest that vitamin intake is the sole reason for reducing specific diseases, healthy food consumption is a better route to good health. * Some people believe that consuming food is not any more likely to prevent the risk of degenerative diseases than taking supplements. Many of the same vitamins in minerals found in whole foods are provided in supplements. Many Americans are struggling to meet daily recommendations in their diet. Poor food consumption is damaging health and a broad array of supplements can...

...NUTRITION PROJECT I think my diet is very interesting and shows both sides of how I can eat. As you can see, three of my entries show how much salt, fat and calories I can consume along with not drinking enough water. There is also an entry I added to show my current eating habit which is optimal. I just purchased an elliptical/treadmill and started working out for at least an hour a day with my heart rate up and sweating. When I start working out, I am conscious of what I eat. I drink more water, lay off processed and refined foods and honestly I feel better mentally and physically. I will begin with the first three entries logged on my fitness pal. My diet is defiantly high in sodium. I should know better because at the age of 25 (and in a high stress/competitive nursing school) I was hypertensive and taking 10 mg of lisinopril a day. I feel poor diet choices, lack of exercise and low water consumption may have added to this. Luckily now, at the age of 31, I am no longer taking any sort of medication for this. The average recommended dietary intake of sodium for adults is 1,500 mg. The human body actually only needs approximately 180-500 mg/day according to the Centers for Disease Control and prevention. Their website also gives information stating the tolerable level of sodium defined: which is "the highest daily level of sodium that poses no risk of adverse health effects to almost all individuals" is 2,300...

...There were two assignments that I enjoyed doing during this class. These were the three day diet analysis and the three day activity analysis. In doing these I learned a lot about my eating habits and which changes I needed to make to receive the proper balance of nutrition for a healthy living. I thought I ate real well, but there were important nutrients that I was not getting enough of, such as calcium and Vitamin C. The three day activity analysis was fun to see how many calories I was burning. I enjoyed how it used even getting out of bed and brushing your teeth in this analysis. I am an extremely active person, and don’t sit down much, but I didn’t realize how many calories I was using in a day. The assignment that has affected my life and my eating habits the most is the three day diet analysis. Knowing that I wasn’t eating all of the necessary foods for a healthy diet made me want to change it. So, now I am more aware of which types of foods, especially fruits and vegetables that I need to intertwine in my diet. The easiest way for me to do this is to pick foods from each color of the color wheel, so that I know I am getting a variety. Over all I have enjoyed this class and learning not only about a healthy diet, but different diseases.

...Nutrition I have always had a strong desire to help others.  Nutrition has always fascinated me. I constantly look for updated information on our health and nutrition, but I haven’t had the opportunity to consult with anyone in my field, until I met Renita Dastrup. The interview gave me a great outlook on nutrition.  As a result of the interview I found out that I want to study the physiological approach to nutrition rather than the Chemistry aspect. After a few days of playing phone tag, I contacted Dastrup. She gladly accepted the opportunity to let me interview her. I was able to meet with her, it was late afternoon. A slight breeze blew and the heavy clouds moved slowly resulting in brief moments of piercing sunlight. We agreed to meet outside the clubhouse of my apartment building. She is a blonde-haired blue eyed lady, she has and athletic build.  As she looked in my direction,  her eyes lit up, and the corners of her mouth displayed her smile, it beamed like a perfect pearl necklace. The dimples in her cheeks appeared as her whole face showed amusement upon meeting me. Dastrup a mother of two, worked as a Real Estate and Mortgage Broker for over eighteen years.

Nutrition plays an important role in the reducing the risk of infection and wound healing after surgery. Understanding how nutrition can benefit as well as hurt recovery after surgery when caring for all patients. Malnutrition as a result of critical illness has been defined as ‘acute disease or injury-related malnutrition’, which is associated with severe, acute inflammation. During periods of critical illness, the inflammatory response elevates energy expenditure and nitrogen excretion that is only partially attenuated by the provision of nutritional support. Contributing to this weight loss is inadequate nutritional intake with ICU patients only receiving 60–80% of their prescribed energy and protein requirements.( JCN, 2014) These suboptimal intakes result from delays in initiating feeding and feed interruptions due to nausea, vomiting, abdominal distension, large gastric aspirates, tube displacement, investigations and prolonged fasting for procedures. Oral diet following extubation from mechanical ventilation has also been shown to be inadequate. Peterson assessed the oral intake of 50 patients for the first...

...Comparing Nutrition Labels Nutrition labels are intended to help people make healthier choices when it comes to the food they eat. Consumers recognize nutrition labels as tools to help improve their health and can find an abundance of valuable information pertaining to specific items. The presence of nutritional information may influence the consumer to switch from unhealthy food products towards healthy food products, but only if they understand how to read a nutrition label. Reading a food label at first can be confusing, however it will help the consumer to select foods that will provide the accurate amount of nutrients and energy that the body needs. There are specific things to look for on a food label that can differentiate an unhealthy food from a healthy food. When comparing an avocado to Ben and Jerry’s Chunky Monkey ice cream, we know that an avocado is the healthier choice, but it is important to understand why. When comparing nutrition labels, the first place you should start is the serving size and the number of servings in the package. Serving size is used to make it easier to compare similar foods. The serving size on a package affects the number of calories and all nutrient amounts within the product. For example, the serving size for an avocado is based on 1/5 of a medium avocado, or 1 oz. With such a small portion size, an avocado is packed with vitamins, minerals, and essential. Conversely, Ben and Jerry’s Chunky Monkey nutrition label offers a much larger...
