USDA Dietary Analysis

For this project, Kayla and Kathy wanted to know how many calories they ate per meal in proportion to the USDA regulations. They also wanted to compare the percent of macronutrients; protein, carbohydrates and fat, they ate compared to the USDA dietary guidelines. They believed that calculating the mean would show the data the best because it constricted the mass amount of data collected in this study. Kathy and Kayla wanted to analyze these specific components because they are prominent factors in the everyday diet. Through comparing the data sets of Kathy, Kayla, and the USDA guidelines, there a few noticeable differences and similarities. The following bar graph displays the average amount of macronutrient intake per day: These pie charts…show more content…
Kathy ate an average of 1211.04 calories per day throughout the experimental week and Kayla ate an average of 1266.29 calories per day. Using the pie charts, one can infer that the data shows that Kayla ate more of her calories during lunch at 43%, while Kathy at the majority of her calories during dinner at 44.2%. Kathy ate an average of 170.71 calories for breakfast, 505.57 calories for lunch, and 534.76 calories for dinner. Kayla ate an average of 259 calories for breakfast, 544.71 calories for lunch, and 462.57 calories for dinner. These numbers, as well as the wedge sizes and percents shown on the pie graphs allows the data to be analyzed such that Kayla has a greater caloric intake during breakfast than Kathy. Kayla’s average caloric intake for lunch was greater than Kathy’s by 39.57 calories. Kathy’s average caloric intake for dinner was greater than Kayla’s by 72.19 calories. The USDA recommends that an equal distribution of caloric intake for each meal is healthy; 33.3% of daily calories eat at each meal. Kathy and Kayla did not really follow these guidelines, as their distribution was not equal between meals. Kathy at 14.1% of calories at breakfast, 41.7% of calories at lunch, and 44.2% of…show more content…
They also learned about the percent of macronutrients and the amount of calories they ate per meal in proportion to the USDA regulations. In brief, Kayla and Kathy have eaten close to the guidelines for their intakes of the macronutrients, fat and protein, with their deviations in between +18.014 and - 17.97. However, in the carbohydrate category, Kayla’s deviation from the USDA guideline of 225 grams is -62.93 grams, and Kathy’s with her deviation as -48.37. They learned that though their fat and protein consumption are rather healthy, their carb intake needs to be changed in order to have a healthy eating habit. To summarize, their average calorie proportions, are a little bit similar when compared together. However, Kathy had a higher in calorie dinner, but low calorie breakfast. Kayla, in this topic, had a more proportioned calorie distribution than Kathy. Kayla has a standard deviation of 148.89, while Kathy had a standard deviation of 201.84. With Kayla’s standard deviation being the one closer to the number zero (meaning that the diet would be exact with the USDA guidelines), Kayla had the better of the two diets in that

    (moderate activity). Their dietary intake was assessed by three-day food records that included two weekdays and one weekend day. Instructions on how to record foods and beverages consumed were given to each gymnast with pictures and common household measurements to determine portion size. They were also asked to record any medications or supplements they were taking. Nourish-Check, with access to the USDA Nutrient Database, was used as a standard for nutrient intake. For analysis, the gymnasts were divided
