2.1.1. National Health and Nutrition Examination Survey (NHANES) 2015–2016
2.1.2. Healthy Eating Index HEI-2015

2.2.1. Food and Nutrient Database for Dietary Studies (FNDDS 2015–16)
2.2.2. National Food Prices from the USDA
2.2.3. Population-Specific Weighted Modeling Variables
2.2.4. Cost and Nutrient Density of Modeling Categories
2.2.5. Healthy US-Style Food Pattern
2.3. Quadratic Programming (QP) Optimization Models
- Model 1, H TFP: This model determined the composition of a “cost neutral” H-TFP market basket.
- Model 2, H-TFP pork: In this model, pork replaced beef and poultry and was the only source of meat. The goal was to determine whether a TFP with pork as the only source of meat would conform to Dietary Guidelines and satisfy all nutrient needs with no increase in cost. The permitted amounts of the modeling categories of beef, poultry, and cured meat were each set to zero. The constraints on having minimal and maximal amounts of meat and poultry (as per USDA Healthy US-Style Food Plan) were removed. The amounts of seafood, eggs, and nuts and seeds were determined by the QP algorithm. The QR algorithm then searched for a healthy food plan that would satisfy all nutrient requirements. In this model, cost was allowed to increase by 0.07 to achieve a feasible mathematical solution for females aged 51–70 y.
- Model 3, Vegetarian: In this model, the permitted amounts of the modeling categories of beef, poultry, cured meat, seafood, and mixed dishes with meat, poultry, or seafood were all set to zero. The requirement to include a minimum amount of seafood (per US-Style Healthy Food Plan) was removed. The requirements to include minimum amounts of “meat + poultry + egg” and total protein foods were set to 0. The range for eggs was set at between 6 and 25 g/day. The QP algorithm then searched for cost-neutral vegetarian market baskets that would satisfy all energy and nutrient requirements.
