...I think the assignment that I enjoyed the most was the Lifespan Nutrition needs Presentation. I found that before this assignment I did learn a lot; basically what are healthy food to eat and what unhealthy foods can do to your body. To me everyone knows that they should eat healthy and such but at least for me I found it more interesting to find out what I am supposed to eat as I grow up; and to also divide it between man and woman made it interesting to see any differences as well. I also though found the Multivitamin Review to be very informative. I printed everything out actually because I think it will be extremely helpful to know what vitamins and minerals that each food has. To know how much sodium is in either chicken or beef. I find it very helpful in making grocery list and just using to help change my eating habits in my life. I think the Multivitamin Review has definitely affected my life in terms of everyday health and nutrition habits. This whole class had helped me drastically concerning my family and I eating habits. Before this class my family and I didn’t really care about what we ate. If we were hungry, we ate. I did a little bit, trying not to eat fast food or going out all the time, but it was hard when my husband has such a high metabolism that he could eat fast food and junk food all day and not gain a pound. However, after this course, and all the information and tips that I know now; my family will be eating healthier, smarter, and much...

If you read other materials while writing your paper, but you did not actually cite them, you may want to include them on a separate page; since they are not actually cited, they must not appear on the works cited or reference page. • You must list all sources that you cited in your paper, including dictionary and encyclopedia entries. • Attention to detail in a works cited or references page is important because it can help you to avoid plagiarism, it demonstrates academic integrity, and it helps your reader to find and use the same sources that you did. • Regardless of whether you use a references or works cited page, your entries must be listed in alphabetical order based on the first word of the entry (usually the author’s last name, but sometimes a piece may not have an author, so you will have to use a different piece of information.

Nutrition health and life. My favorite assignment was the three day diet analysis. I have learned so much about my current diet and what I needed to change to make it healthier. I thought I was eating a balanced diet and found I was lacking in almost every area and eating way to much sodium. I am starting to watch the labels on the food I buy watching for that sodium that is so high in so many foods. There are several assignments that have affected me and some of my nutrition habits are the three day diet analysis, the dehydration assignment multivitamin review, and the lifespan nutrition needs. From the three day diet analysis and the lifespan nutrition needs I have learned what I need to eat and what I need to watch for in my diet now and going forward. The dehydration assignment taught me about needing to drink water. Drinking water is a challenge for me I drink too much diet soda and sugar free flavored tea. I am now making it a habit to drink my daily water requirement every day. The multivitamin review made me realize that my vitamin has too much of quite a few vitamins and minerals and is very lacking in others. I have since found a vitamin that is more balanced in all of its ingredients. Overall I think this course has helped me in my diet and activity level. I have been improving my lifestyle for the past few years and now I have learned what I need to improve on going forward. I thought I was pretty balanced in most areas but have found I needed to......
