Autonomous Multi-Member Household Dietary Optimization & Bioavailable Nutrition Modeling

A rigorous algorithmic framework transforming multi-member household dietary planning, nutritional therapy, and grocery procurement economics into an exact solvable optimization model. Formulated in accordance with ICMR-NIN 2024 Dietary Guidelines for Indians, FSSAI statutory standards, and Digestible Indispensable Amino Acid Score (DIAAS) protein kinetics.

1 Mathematical Formulation of Household Nutrition

Conventional meal planners rely on generic recipe databases or static single-person caloric estimates. In real multi-generational households, meal planning is a complex constrained system: multiple individuals share common cooked dishes (lunch and dinner) while requiring distinct personal nutrient intakes, activity multipliers, and medical dietary restrictions.

Our mathematical optimization engine models every grocery item, meal slot, and family member across a multi-day planning horizon through exact linear and integer decision variables.

Core Optimization Objective: Multi-Objective Trade-Off

Balancing Procurement Budget vs. Palatability & Taste Satisfaction

The engine simultaneously minimizes grocery expenditure and maximizes family culinary satisfaction using a configurable Pareto weighting factor:

Procurement Cost Minimization Calculates actual bulk grocery purchase costs across all required food items, rewarding seasonal and cost-effective nutrient sources.

Palatability & Variety Maximization Scores meal preferences across each individual family member, ensuring high adherence and culinary enjoyment.

Clinical & Operational Constraint Families

Precise Caloric Energy Balance: Daily caloric intake is strictly constrained within ±5% of each individual member's Total Daily Energy Expenditure (TDEE), preventing caloric deficits or unwanted surplus.

45 Bioavailable Micronutrient Bounds: Every essential mineral and vitamin is bounded between ICMR-NIN 2024 Recommended Dietary Allowances (RDA) and Tolerable Upper Intake Limits (UL), adjusted for digestive absorption efficiency.

Essential Amino Acid Completeness: Guarantees complete protein bioavailability with Leucine ≥ 44 mg/kg and Branched-Chain Amino Acids (BCAA) ≥ 96 mg/kg, ensuring high DIAAS scores across vegetarian and mixed meal combinations.

Shared-Pot Cooking Proportionality: Common cooked preparations (staples, dals, curries) are cooked in a single family pot, with individual serving portions mathematically allocated based on each member's caloric share of the household total.

Variety Memory & Culinary Rotation: Anti-fatigue rotation rules prohibit repeating identical staple or pulse dishes consecutively within a rolling 3-day window.

2 Nutrition & DIAAS Bioavailability Kinetics

45 Bioavailable Nutrients

Rather than tracking crude dietary mass, our database models bioavailable absorption factors across minerals and vitamins (e.g. non-heme iron absorption modifiers, phytate-to-zinc molar ratios, calcium-to-phosphorus balance, and active vitamin A retinol equivalents).

Therapeutic Medical Modifiers

Automated clinical constraints dynamically adapt recipes for common chronic and metabolic conditions:

• Diabetes: Daily Glycemic Load strictly capped (GL ≤ 80) with high dietary soluble fiber.
• Hypertension: Strict sodium restriction (≤ 2,000 mg/day) balanced with DASH potassium targets.
• Kidney Care (CKD): Controlled protein (≤ 0.8 g/kg body weight) with strict phosphorus management.
• Bone Health: Calcium-to-phosphorus molar ratio optimized between 1:1 and 1.5:1.

3 Shared-Pot Cooking & Grocery Logistics

Cooking individual dishes for every family member is impractical. The engine models proportional shared-pot preparation: the primary lunch and dinner staples, dal, and vegetable preparations are prepared in bulk, with portion distribution dynamically scaled according to each member's personal caloric share of the family total.

Simultaneously, parallel individual substitutions (such as vegetarian or egg/fish alternatives) are harmoniously balanced within the same total household grocery procurement schedule. Items are categorized into weekly perishability buckets (1–3 days for leafy greens, 5–7 days for root vegetables, 30 days for dry staples) to minimize kitchen food waste.
