DIETARY ANALYSIS ASSIGNMENT LIFESCI 2N03 400126922 Dina Khalaf

Proper nutrition is one of the most essential elements of being a healthy individual and living a long life. What is it that we consider “proper nutrition”? In the field of nutrition, Dietary Reference Intakes are used as reference values to assess nutritional quality (Institute of Medicine (US) Food and Nutrition Board, 1998). Estimated Energy Requirement (EER), Acceptable Macronutrient Distribution Range (AMDR) and Recommended Dietary Allowance (RDA) are different DRIs that are used in Nutrition. The EER is the dietary reference for energy intake and is dependent upon height, weight, age, sex, physical activity, energy intake and energy expenditure (Gerrior, Juan, & Basiotis, 2006). RDA is defined as the average daily level of intake sufficient enough to meet the nutrient requirements of nearly all (97%-98%) healthy people. In addition to RDA, the Acceptable Macronutrient Distribution Range provides recommendations for macronutrient intake in the context of a complete diet. The AMDR expresses intake recommendations as a percentage of total caloric intake (Wolfe, Cifelli, Kostas, & Kim, 2017). In this assignment, I used a website called Eatracker to review my personalized nutrient assessment results. This was done by recording all the food I consumed across a 3-day period onto Eatracker after inputting my weight, height, gender and age. Eatracker provided me with a detailed analysis of my daily nutrient intake. My daily physical activity was also recorded on eatracker. My daily nutrient intake was then used to make comparisons against the relevant current dietary standards taken from the essential DRIs guide. The main purpose of this assignment is to assess the adequacy of my daily nutrient intake using self-reported dietary assessment methods.This assignment has not only allowed me to apply my theoretical knowledge of Nutrition, but has also given me the opportunity to reflect on my Diet. I am now better informed of changes I need to make in my diet to meet my nutritional needs.

By tracking my food intake for three consecutive days using Eatracker, I was provided with a detailed nutrient assessment. Tables 1 and 2 were created to make comparisons between my nutrient intake collected from Eatracker and recommended intakes (DRIs, RDASs, AMDR, EER and Canada’s Food Guide). I compared my vitamin and mineral intake during all 3 days to the Recommended Dietary Allowances (RDA).Moreover, AMDR values were compared to my protein, fat and carbohydrate intake across this 3 day period. Finally, my caloric intake for all three days was compared to my Estimated Energy Requirement (EER). Throughout all three days, I exceeded the 20-35% AMDR for fats.My protein and carbohydrate consumption for all three days were within the Acceptable Macronutrient Distribution Range of 10-35% for proteins and 45-65% for carbohydrates. I consumed much less than the recommended 8 servings of vegetables and fruits during this period. Furthermore, my dietary fibre intake was much lower than the recommended 25 grams per day for all three days. Niacin consumption was observed to be much higher than the recommended RDA each of the 3 days. My sodium intake for all three days was also extremely high, exceeding the 1,500 mg/ day Recommended Daily Allowance. Consumption of the other vitamins and minerals were either too high or too low when compared to Dietary Reference Intakes. Day 1, was the only day that I performed physical activity as shown in Table 3. This physical activity was brisk walking for a duration of 40 minutes and was classified by Eatracker as “moderate intensity activity”. The activity feedback informed me that 40 minutes of the required 150 minutes of exercise per week was performed. During the other 2 days, no physical activity was performed.

Sample calculation: The following is a sample calculation of my saturated fat intake as a % of total energy on Day 1 of tracking my food intake (Monday, October 21st, 2019). The Result I calculated (15%) was then compared to the Dietitians of Canada/ Academy of Nutrition and Dietetics recommendations (Nutrition and Athletic Performance, 2016)

Table 3: Physical activity performed during 3 day period that food was tracked. The only day where physical activity was performed was on Day 1 (oct 21st). This included Brisk walking for 40 minutes, considered to be moderate intensity exercise. This data was collected using (eaTracker, 2019). Physical activity

Comparisons drawn between DRI values and my nutrient intake made it evident that my nutrient intake is extremely inadequate. Most of my daily nutrient intake fell below or above the recommended daily intake values across the 3 day period.The main cause of concern was the high fat, high sodium and low fruit and vegetable intake during this three day period. One of the major findings of this assignment, was the high level of fats consumed in my diet. During all three days, the amount of fat I consumed exceeded the Acceptable Macronutrient Distribution Range of 20-35%. During the third day, I consumed the highest amount of fat, constituting 48% of my daily energy intake. Fats are important macronutrients that have several functions in the body. Dietary fats provide our body with energy, form structural components of our cells and carry several biological functions (Thompson, Manore, & Sheeshka, 2014). However, like any other nutrient , an excess amount of fat can be very harmful. Diets high in fat have been linked to cancer and heart disease, North America’s two leading killers ( Institute Of Medicine (US) Committee on Diet and Health, 1992). It is particularly saturated fats, that have been shown to have detrimental effects on the body ( Institute of Medicine (US) Committee on Diet and Health,1992). The Dietary Guidelines for Americans and Eating Well with Canada’s food guide recommends that the proportion of energy coming from saturated fats should be less than 10% (Nutrition and Athletic performance, 2016). My saturated fat intake as a % of total energy was

calculated to be 15%, which is higher than the recommended intake. Reducing dietary saturated fats has been the number one recommendation for reducing the risk of cardiovascular diseases for decades (Hooper, Summerbell, Higgins, Thompson, Capps , Smith , & Ebrahim, 2001). A diet high in saturated fats is particularly a risk to me, due to my genetic predispositions to developing heart disease. By following experts recommendations of reducing my fat consumption, I could lower my chances of developing cardiovascular disease in the future. Another red flag found during the analysis of my diet, is the high levels of sodium that I consume. Sodium is the main mineral found in table salt.The vast majority of sodium intake is estimated to come from processed foods and restaurant foods ( Maalouf, Cogswell, Gunn, Curtis, Rhodes, Hoy, & Merrit, 2013). My diet is made up of largely of fast food, due to its convenience and availability to me. This provides an explanation for the high levels of sodium in my diet. Sodium is essential for cellular homeostasis and physiological functions (Farquhar, Edwards, Jurkovitz, & Weintraub, 2015). However, if sodium exceeds the recommended intake, it can contribute to high blood pressure (Farquhar et al., 2015). The World Health Organization (WHO) strongly recommends that individuals lower their dietary salt intake to reduce the number of deaths from hypertension, cardiovascular disease and stroke (Ha, 2014). To lower the amount of sodium in my diet, I need to decrease the amount of salt I add to my food and avoid processed foods that have increased sodium levels.Two very important components of a healthy diet are vegetables and fruits. Diets high in fruit and vegetables are widely recommended for their health promoting properties (Slavin & Lloyd, 2012). Fruits and vegetables are rich in vitamins, minerals, fibre and phytochemicals (Slavin & Lloyd, 2012).Fibre alone has a wide array of benefits, including reducing the risk of colon cancer, preventing intestinal problems and lowering

the chance of developing heart disease (Thompson et al., 2014). Canada’s Food Guide recommends an intake of 8 servings of fruits and vegetables per day (eaTracker, 2019). My Average intake across the 3 day period was only 4.1 servings of fruit and vegetables, indicating my diet is low in fruits and vegetables. This could be used to further explain the low levels of vitamins and minerals in my diet. Being deficient in vitamin D, I take daily 1000 IU vitamin D supplements to raise my vitamin D levels. However, I am not always consistent with them, explaining my low vitamin D levels. This assignment has led me to the conclusion that my overall diet is inadequate nutritionally. If I continue to eat the way I do, I could develop nutrient deficiencies and serious health conditions. By incorporating more fruits and vegetables into my diet, I would be increasing the amount of fibres, vitamins and minerals that I consume. Eating less junk food would result in lower levels of saturated fats and sodium in my diet, lowering my risk of high blood pressure, cardiovascular disease and cancer. After making these changes to my diet, I could use the same self-reported dietary assessment methods used in this assignment, to assess my nutrient intake in hopes of seeing improvement.
