2. INTRODUCTION
• Good nutrition is essential for our overall health and
well-being. It provides the necessary nutrients to
support our body functions, prevent diseases, and
maintain a healthy lifestyle.
• Assessing our dietary habits is crucial to
understanding whether we're meeting our nutritional
needs. In this presentation, we’ll study various
methods of dietary assessment, focusing on both
food and fluid intake.

3. WHY ASSESS
DIETARY
INTAKE?
Highlight the importance of
dietary assessment for
health and nutrition.
It helps identify nutrient
deficiencies, excesses, and
imbalances.
It enables personalized
recommendations for
improved health.

4. TRADITIONAL
METHODS - 24-
HOUR RECALL
Subjects are asked to report all foods
and beverages consumed in the past
24 hours. This can be done via
telephone or face-to-face interview.
Advantages: Quick, Does not alter
eating behaviors, Less subject burden
Limitations: Relies on memory, not
representative of usual intake.

5. TRADITIONAL METHODS - FOOD FREQUENCY
QUESTIONNAIRES (FFQ)
• Subjects report how frequently certain food and
beverage items were consumed over a specific period
of time. Most FFQ versions ask portion size questions
of every food item, as well as general questions about
common cooking.
• Advantages: Long-term assessment, capturing food
patterns, Captures habitual intake
• Limitations: Relies on reporting accuracy, may not
capture recent changes.

6. TRADITIONAL METHODS - DIET RECORDS (FOOD
DIARIES)
• Subjects record all food and beverages consumed over three consecutive days
(two weekdays and one weekend day).
• Advantages: Detailed data, identifies daily variations, Does not require recall,
Allows self-monitoring which can influence behavior change, Provides typical
meal and food pattern information
• Limitations: High Burden, Requires multiple records

7. TRADITIONAL
METHODS -
BIOMARKER
MEASUREMEN
TS
Examples:
Blood
Tests:
Urine
Metabolic
Markers
Nutritional biomarker is a characteristic that can
be objectively measured in different biological
samples and can be used as an indicator of
nutritional status with respect to the intake or
metabolism of dietary constituents

8. TRADITIONAL
METHODS -
BIOMARKER
MEASUREMEN
TS
Advantages: Objective data,
useful for research, specific
information.
Limitations: Expensive, may
not reflect recent changes,
complex interpretation.

9. ADVANCED METHODS - DIETARY PATTERNS
ANALYSIS
• Dietary Pattern Analysis is a method to identify and characterize the collective
consumption of foods and beverages over a defined period, aiming to assess the
overall dietary habits of individuals or populations.
• Examples:
1. Mediterranean Diet
2. Western Diet
3. Plant-Based Diet

10. ADVANCED METHODS - DIETARY PATTERNS
ANALYSIS
Advantages: Identifies overall eating habits, real life
picture, actionable.
Limitations: Subjective interpretation, data collection,
changes over time.

11. ADVANCED METHODS - NUTRIENT ANALYSIS
• Nutrient Analysis is a scientific method used to evaluate the nutrient content of
foods and beverages. It involves quantifying the various essential nutrients, such
as vitamins, minerals, proteins, fats, carbohydrates, and dietary fiber, present in a
given food item or meal.
• Key Aspects of Nutrient Analysis:
1.Quantitative Assessment.
2.Labeling and Regulation
3.Dietary Planning

12. ADVANCED
METHODS -
NUTRIENT
ANALYSIS
Advantages: Precision ,
customisable.
Limitations: Sample
variation, labor and
resources, potential errors.

13. EMERGING TECHNOLOGIES - MOBILE APPS AND
DIGITAL TOOLS
• "Emerging technologies in the context of dietary assessment refer to mobile
applications (apps) and digital tools designed to facilitate the monitoring, analysis, and
management of individual or population dietary intake.
• Advantages: Convenient, real-time data collection,
Personalization
• Limitations: User commitment, accuracy depends
on input, subscription charges.

14. EMERGING TECHNOLOGIES - MOBILE APPS AND
DIGITAL TOOLS
Some Free Apps
• Eat This Much
• Simple Habit
• FoodData Central India (FSSAI)
• HealthVault India
• Nutritionix

15. EMERGING TECHNOLOGIES - WEARABLE
DEVICES
• "Wearable devices in health monitoring refer to compact, sensor-equipped electronic gadgets
designed to be worn on the body, typically as accessories like wristbands, smartwatches, or
other portable devices.
Examples:
Fitbit: A popular brand that tracks activity, heart rate, sleep, and some models offer food tracking
features.
Apple Watch: Besides activity tracking, it can also monitor heart rate, ECG, and offers health
apps.
• Advantages: Continuous monitoring, insights into health impact, motivation.
• Limitations: Battery life, accuracy challenges, cost.

16. SELF-MONITORING AND BEHAVIOR CHANGE
• It involves the systematic observation, recording, and analysis of one's own
behaviors, activities, or physiological responses, often with the goal of promoting
positive behavior change.
• Benefits:
Awareness, Accountability, Behavior Change.
• Examples:
Food Diary, Activity Tracker, Mood Journal.

17. SELF-MONITORING AND BEHAVIOR CHANGE
• Limitations:
• Honesty: To get the best results, you need to be honest in your tracking.
• Consistency: Self-monitoring needs to be consistent for it to be effective.
• Realistic Goals: It's important to set achievable goals based on your findings.

18. PERSONALIZATION AND NUTRITIONAL
RECOMMENDATIONS
• When it comes to nutrition, there's no "one size fits all." Personalization is the key
to creating dietary recommendations that work best for each individual. By
considering unique factors like age, health status, activity level, and preferences,
we can tailor nutritional advice to optimize health and well-being.
• How It Works:
1.Assessment
2.Analysis
3.Tailoring Recommendations

19. CHALLENGES AND CONSIDERATIONS
Challenges:
