In life, many people participate in various daily events and activities that help them enjoy being who they are. People may enjoy getting together with friends, going to the mall, going to an amusement park or simply finding relaxation in nature. However, a big part of everyone’s life is of course eating and many people find pleasure in doing so. Eating is a very enjoyable and delectable must for everyone but should be done so, like everything in life, in a smart and intelligent way. Being smart and perceptive when eating is a large part of nutrition.

To determine the level of my fiber intake from a 3 day sample of my diet, I performed a Prospective Diet Analysis. On average, I consumed 22.3 grams of fiber, just missing the recommendation of 25 grams. Coherent to the findings of the related studies, my cholesterol intake decreased and by the third day totaled 124.5 mg, which relates to 42% of the Daily Recommended Intake of 300 mg.

Proper nutrition is important in maintaining a long and healthy life. Most Americans are rushed due to their busy work schedules, and do not take the time to plan their diets properly. Like me, most Americans are unaware of the importance of eating a healthy diet and consume too many foods without the proper nutrients. Throughout my life I have been fortunate. I have not had any major health problems, and have been able to consume most foods without having to worry about gaining weight. These last two years, however, I started to gain weight and have become concerned with my diet. Changing my poor eating habits has been difficult for me, however, having this assignment has taught me that it is not as difficult as I previously

In my Diet Journal, I recorded all the food I ate over the weekend with the best accuracy I could attempt to do. But one of the factors that made my food diary inaccurate was that I couldn’t find every detail and percentage of fat, carbohydrates, and proteins in everything I ate. Also, all of the amounts and servings were approximations, not exact amounts. I was able to record everything I ate, but accuracy may have been affected by estimations and sources. The calorie intake I had over the three day period ranged from 1900-2500 calories. This was over my 1800 BMR, due to the food choices and fluctuation in diet.

Please do not use cell phone to text during class as it distracts other students.

Determine the energy per gram (kcal/g) that is estimated on the package for each food

Keeping in range your micronutrient is very important, the range provides a guide to a well-balanced nutrition in which you should not exceed the recommended ratios in order not to create excess energy in thus converting to fat. The lack of micronutrients is also important to keep in mind. Lack of these nutrients can cause malnutrition that can lead to disease complexity disorder and long term damage to your organs.

Purpose: The purpose of the lab is to find out the change in mass of the mealworms and the potato slice and compare them. It is also to find out how much carbon dioxide is in the container at the beginning and the end of the experiment.

We then recorded the initial color. We placed each tube in boiling water for one minute and recorded the color results and gave our conclusion. To test for starch using Lugol’s solution, we reused the test tubes and added a squirt of the solution. We recorded the final color and then our conclusion for each content. To test for lipids using paper towels, we placed a drop of solution and we let it stand for one minute. We then recorded our observation, if it was dry or not dry and wrote our conclusion for each sample. To test for proteins using Biuret’s reagent, we added a squirt of stock solution plus a few drops of Biuret’s solution. We wrote the initial color. We then shook the solution and waited for two minutes before recording the results. After the two minutes, we wrote the final color and conclusion for each content. For the unknowns, we wrote the odor and appearance of each content and then tested the benedict’s, starch, lipid, and protein test and wrote our conclusion.

A small calorie(symbol:cal) - 1cal is the amount of energy to required to raise one gram of water by one degree Celcius.

     Since we have been learning about nutrition in class, our task was to record a food log. Nutrition requires a well-balanced diet containing nutrient and vitamins like amino acids and fatty acids. Over the past seven days I have been recording and have been looking very carefully at my intake of nutrients, minerals, vitamins, and fats. In our task, the objective was to record the basic foods we ate during the period of seven, but it did not require recording every single detail or our intake of food. Doing this food log was a pain and it was disturbing because I never wrote about what I ate like breakfast, lunch, dinner, or additional meals. I found this food log useful because it helped me learn what I

The aim of this experiment was to test the heat of combustion over a period of time, and the energy required to combust alcohols with different carbon chain levels. It was hypothesised that the higher the carbon chain of the alcohol present, the faster the heat of combustion will occur. Meaning more energy will be released for a higher carbon chain. After calculating the results from the experiment it was found that the hypothesis was partially supported. The reasoning for this is as the alcohol that posses a higher carbon chain, generally increased there reaction rates. However there were a few exceptions to this rule.
