Nutrition / Diet

Priority resource reviews

• Estimated Energy Requirement (EER): this is our highest-priority nutrition-equation update. The current page is based on the 2002/2005 DRI framework and still references MyPyramid. We plan to implement the 2023 National Academies Dietary Reference Intakes for Energy and clearly distinguish EER from BMR/RMR.
• BMR Multi-Calc: we plan to retain Harris-Benedict, revised Harris-Benedict, Mifflin-St Jeor and Schofield for comparison while replacing the outdated EER component, revisiting activity multipliers and improving the explanation of predictive uncertainty versus indirect calorimetry.
• Harris-Benedict / RMR / Schofield pages: we plan to simplify repeated background material, remove outdated “latest guideline” wording, improve activity-factor explanations, and clarify when body composition or illness makes prediction less reliable.
• Ireton-Jones Critical-Care Energy: we plan to update its role relative to indirect calorimetry and current ASPEN critical-care nutrition guidance instead of presenting the older predictive-equation literature as the contemporary standard.
• Protein Requirements Calculator: we plan to preserve the core DRI values while replacing older athlete references and broad claims about excess protein with a modern framework for healthy adults, athletes, older adults, sarcopenia, pregnancy, illness/recovery, obesity and CKD.
• Essential Amino Acid / Protein Review: we plan to update food-protein quality, leucine/anabolic response, plant-based patterns, complementary proteins, aging and the difference between minimum adequacy and condition-specific protein goals.
• Total / Soluble Fiber Calculators: we plan to refresh food values using current USDA FoodData Central where appropriate, update cardiovascular and bowel-health context, and better distinguish total fiber, viscous soluble fiber, fermentable fiber and resistant starch.
• Daily Fiber Requirements: we plan to align the explanatory material with current Dietary Guidelines / DRI context and make age/life-stage assumptions clearer.
• Oxalate Calculator: we plan to update the food database, quantify uncertainty across food assays and preparation methods, and connect the tool to modern calcium-oxalate stone prevention rather than implying that broad oxalate restriction is appropriate for everyone.
• Calcium & Vitamin D Requirements: we corrected the portal destination to the appropriate requirements calculator. We next plan to update its clinical context using current NIH ODS material, targeted screening principles, supplementation safety and bone/kidney considerations while retaining the established DRI framework.
• Weight Management Agents: our current table includes historical products such as lorcaserin/Belviq and predates contemporary incretin-based obesity pharmacotherapy. We plan to revise this resource in coordination with Endocrinology so nutrition therapy, lifestyle intervention and current pharmacotherapy are presented within an integrated obesity-management framework.
• BMI / body-composition calculators: we plan to retain the simple equations while improving language around BMI limitations, waist/visceral adiposity, sarcopenic obesity, ethnicity, athletic body composition and the difference between screening and diagnosis.
• TPN Calculator: this is a major clinical-nutrition update. We plan to replace the older indication text, add modern malnutrition/refeeding assessment, enteral-versus-parenteral decision support, macro/micronutrient planning, electrolytes, glucose/lipid monitoring, line safety and ASPEN-linked verification.
• Clinical malnutrition: we plan to add a dedicated screening/assessment pathway rather than treating nutrition support as a calorie calculation alone.
• Food composition: we plan to migrate older manually maintained food tables toward a documented USDA FoodData Central source strategy where the nutrient or food component is represented reliably.
