Nutrition Assessment and Dietary Recommendations Case Study

Introduction and Patient Overview

The patient is a young woman who attributes her disordered eating to a dislike of the unhealthy food her mother prepares and to her job as a salsa instructor, which she feels demands that she regulate her weight. She sometimes eats only one meal per day, occasionally forces herself to vomit when she feels she has eaten too much junk or fried food, and is overly concerned with her weight and diet. She is currently on no medication, although she occasionally takes multivitamins. She weighs 117 pounds and is attempting to return to her former weight of 110 pounds.

Based on her height of 5 feet 2 inches and weight of 117 pounds, her Body Mass Index (BMI) is 21.4. This places her squarely in the normal weight range. For reference, a BMI below 18.5 is classified as underweight, 18.5–24.9 as normal weight, 25.0–29.9 as overweight, and 30.0 or above as obese (U.S. Department of Health and Human Services; National Heart, Lung, and Blood Institute). She is therefore in the middle of the healthy range and does not need to lose weight.

BMI Calculation and Weight Status

A healthy eating plan emphasizes fruits, vegetables, whole grains, and fat-free or low-fat milk and milk products. Several areas in the patient's current diet require improvement.

Dietary Analysis and Areas for Improvement

Breakfast: The patient needs to eat a healthy breakfast, ideally consisting of a nutritious cereal — preferably one containing bran, a beneficial carbohydrate. Benton and Parker (1998) found that breakfast consumption improved memory performance on three tests and that even relatively low glycemic index foods (produced from slowly absorbed carbohydrates) had a positive impact on memory enhancement. Studies have consistently found that breakfast positively influences declarative memory, such as recall for stories and word lists.

Gibson, as cited in Lovett (2007), demonstrated that the type of carbohydrate consumed is more important than the amount, and that even a small quantity of carbohydrate can improve performance on standardized laboratory memory tests. Gibson further found that the best memory-boosting foods were those with a high glycemic index value — in his case, All-Bran cereal — whereas high-GI foods such as coco-pops produced a somewhat lower effect, though still greater than consuming no carbohydrates at all. The current breakfast of fried beans and rice should be eliminated entirely, as fried food is nutritionally counterproductive.

Lunch: The current lunch appears reasonably balanced in carbohydrate, protein, and vegetables, but it may be too small given the patient's high level of physical activity. However, it is also top-heavy on protein and too light on carbohydrates and vegetables. One slice of turkey should be sufficient, while the carbohydrate and vegetable portions should be increased to support her energy needs as an active instructor.

Dinner: Dinner needs modification as well. The carbohydrate load is too high — one tortilla may be sufficient — and any fried components should be removed. With those adjustments, the meal would reflect a good balance of carbohydrate, protein, and vegetables. The patient should also consider making dinner her lightest meal of the day, as some researchers suggest that the heaviest meal is best consumed at midday rather than in the evening.

Missing food groups: There are no milk or dairy products in the patient's current diet. She would benefit greatly from incorporating them, along with greater portions of fish, which is considered a particularly healthy addition. Other factors worth investigating include whether the rice and tortillas she consumes are whole grain, whether the skin has been removed from her poultry, whether her turkey and chicken are low-fat, whether fruits and vegetables are fresh, and the sodium content of her canned beans. I would also recommend incorporating eggs and unsalted nuts, as well as periodic healthy snacks throughout the day. This would reduce her reliance on junk foods.

The patient appears to manage her portion sizes to some extent, though her intake fluctuates. Greater consistency is recommended, along with a conscious effort to keep meals low in saturated fat, trans fat, cholesterol, sodium, and added sugars. She should also drink more water and maintain a regular schedule of three meals per day supplemented by healthy snacks. Given her exercise regimen, a daily intake of 1,200–1,600 calories would be appropriate.

Conclusion

The patient does not need to lose weight. On the contrary, her active lifestyle as a salsa instructor calls for a consistent, balanced eating plan of 1,200–1,600 calories per day that adequately supports her energy expenditure. Key priorities include eliminating fried foods, incorporating dairy, fish, eggs, nuts, and iron-rich vegetables, reducing sodium from processed and canned sources, and ensuring all three daily meals are nutritionally balanced. Adherence to these recommendations would address her elevated sodium and low iron levels, support her physical performance, and reduce the disordered eating behaviors that currently put her health at risk.
