BIO-319 Applied Nutrition

Assignment 11: Three-Day Diet Analysis Project and Eating Behavior Journal

1. Assessment Overview

Unit/Program: Pre-licensure BSN / Health Sciences prerequisite
Course: BIO-319 Applied Nutrition
Assessment Type: Individual diet analysis project with attached logs and worksheet (benchmark assignment)
Placement: Early to mid course, following introductory content on macronutrients, micronutrients, and diet planning
Length: Approximately 1,200–1,500 words of written analysis embedded in a structured worksheet and short narrative sections, plus a three-day food and behavior log
Weighting: 15–20% of course grade and designated as a major project in BIO-319

This project develops your ability to record real dietary intake, evaluate it against evidence-based nutrition recommendations, and design realistic dietary and behavioral changes that support long-term health and disease prevention.

2. Task Components and Submission Requirements

You must submit three required documents together in one upload, as outlined in the BIO-319 Three-Day Diet Analysis Project instructions and rubric.

1. Diet and Wellness Plus Combination Report PDF covering three consecutive days, including two weekdays and one weekend day

2. Eating Behavior Journal documenting food choices and contextual influences across the same three days

3. Three-Day Diet Analysis Worksheet completed in full with thoughtful written responses

If any one of these components is missing, the assignment grade may be recorded as zero until all materials are submitted, with late penalties applied according to course policy.

3. Task Description

3.1 Data Collection: Three-Day Intake and Eating Behavior Journal

Over three consecutive days, including two typical weekdays and one weekend day, record all foods and beverages consumed and enter them into the required diet-tracking software. Export a Combination Report PDF covering those dates.

• Include portion sizes, brand names when relevant, and preparation methods to improve accuracy

• Ensure your personal profile is complete so that dietary reference intakes and energy targets are calculated correctly

At the same time, complete the BIO-319 Eating Behavior Journal for each day.

• Record what you ate, when and where you ate, and the reasons for your food choices such as hunger, stress, convenience, or social context

• Identify patterns such as snacking frequency, emotional eating, late-night intake, or skipped meals

3.2 Three-Day Diet Analysis Worksheet (Written Analysis)

Using your Combination Report and Eating Behavior Journal, complete each section of the BIO-319 Diet Analysis Worksheet. The worksheet guides you through a structured evaluation of dietary intake and eating behaviors.

i. Energy and Macronutrient Intake

• Compare average daily kilocalories and grams of protein, carbohydrate, and fat to your dietary reference intakes and acceptable macronutrient distribution ranges

• Label each intake level as met, high, or low and propose realistic improvement strategies where needed

ii. Micronutrient Intake

• Identify at least three micronutrients where intake is significantly above or below recommendations

• Use reputable sources to suggest food-based strategies for improving balance

iii. Diet Quality and Eating Patterns

• Evaluate overall diet quality using an established framework such as MyPlate or national dietary guidelines

• Summarise key patterns identified in the Eating Behavior Journal and explain how they influence nutrient intake

iv. Health Risks and Long-Term Implications

• Discuss one or two potential long-term health implications associated with observed intake patterns

• Support statements with current nutrition literature or guidelines

v. Nutrition Change Plan

• Propose five to seven specific nutrition and behavior changes for the next month

• Explain why each change is beneficial and how it is realistically achievable

The worksheet expands as you type, and additional rows may be added where required. Responses should reflect engagement with your personal data rather than generic nutrition advice.

4. Assignment Requirements and Formatting

• Length: Approximately 1,200–1,500 words across worksheet sections plus three days of food and behavior logs

• Structure: Use the official BIO-319 Three-Day Diet Analysis Worksheet and retain original prompts

• Sources: Use reputable nutrition references and include at least two to three external sources

• Style: Follow the required referencing style consistently

• Academic Integrity: All intake data and reflections must be your own work

6. Your Study Bay

Average energy intake across the three days slightly exceeded estimated requirements, with excess kilocalories primarily derived from added sugars and solid fats. Replacing one sugar-sweetened beverage and an evening snack with water, fruit, and nuts on most days improves micronutrient density and satiety while reducing overall energy intake. Over time, consistent small substitutions such as these may lower cardiometabolic risk and support healthier body composition (Schwingshackl et al., 2019).

Diet self-monitoring assignments encourage students to develop greater awareness of eating behaviors and their nutritional consequences. Research indicates that structured food tracking combined with reflective analysis improves nutrition knowledge, supports healthier dietary patterns, and increases the likelihood of sustained behavior change among young adults when paired with realistic goal setting (Burke et al., 2018).
