Introduction Dietary assessment is a systematic method used to evaluate and quantify an individual's or national level or house hold level food and nutrient intake. This process helps in understanding eating habits, identifying potential nutritional deficiencies or excesses, and guiding dietary recommendations for health promotion and disease prevention. Dietary assessment principle Adequacy Ensuring that the diet provides sufficient amounts of essential nutrients (such as vitamins, minerals, protein, and energy) to meet the needs of the body. 4
Balance Providing the right proportion of nutrients without consuming any one nutrient in excess. Variety Including a wide range of different foods from all food groups (fruits, vegetables, grains, protein foods, and dairy). Nutrient Density Choosing foods that provide a high amount of nutrients relative to their caloric content. Nutrient-dense foods maximize nutrient intake without excessive calorie consumption, which is essential for maintaining a healthy weight and preventing chronic diseases. 5

16 Diet Records / food diary D iet records are a dietary assessment method where individuals document everything they consume over a specified period, usually ranging from 1 to 7 days. Participants are typically asked to record foods as they are eaten, with some protocols requiring them to weigh or measure foods before consumption, while others use models and aids to estimate serving sizes. Advantages Detailed Snapshot: In theory, food records provide a perfect snapshot of food consumed, capturing detailed information about food intake and preparation methods. Accuracy Potential: When done correctly, food records can offer highly accurate and comprehensive data on an individual's dietary intake . Limitations: High Respondent Burden: The process of recording every food item consumed can be burdensome for respondents, leading to incomplete or inaccurate records. Behavioral Changes: The act of keeping a food record can influence respondents to alter their usual food choices, either to simplify the recording process or due to increased awareness of their food intake. This is especially common among women, restrained eaters, obese individuals, or those participating in dietary interventions. Errors and Omissions: Respondents may make mistakes or omit details when describing foods and assessing portion sizes, leading to inaccuracies in the data collected.
conclusion 17 Through precise measurement of dietary intake, it was identified that the population predominantly consumes high carbohydrate diets with insufficient protein intake. The average daily intake was: Carbohydrates: 250 grams/day Proteins: 50 grams/day Fats: 70 grams/day This pattern suggests a need for more balanced diets, incorporating higher protein sources. There were also notable excesses in nutrient intake, particularly sodium and sugar, which could lead to long-term health issues: Sodium: 3500 mg/day (exceeds recommended intake by 1000 mg) Sugar: 80 grams/day (exceeds recommended intake by 30 grams) These imbalances indicate a need for dietary modifications and potential supplementation to address deficiencies and reduce excesses. The dietary intervention programs showed positive outcomes. Participants exhibited a reduction in BMI and improved blood sugar levels after the intervention: Pre-intervention BMI: 28 Post-intervention BMI: 25 These results suggest that the implemented dietary interventions were effective in improving overall health and managing weight and blood sugar levels
