How IBDPal nutrition baselines work

  • Baseline macronutrient and micronutrient targets follow U.S. Dietary Reference Intakes (DRI) from NIH, adjusted by age and sex.
  • Calorie, protein, and fluid estimates also consider basic profile inputs such as current weight. A single formula like 30 kcal per kg is not enough for every patient.
  • Higher calorie, protein, vitamin, or mineral needs during active disease, malabsorption, or deficiency are clinical decisions made with your gastroenterologist or IBD dietitian.
  • IBDPal tracks food and fluids against general reference levels. It does not prescribe supplements or replace medical nutrition therapy.
  • AGA guidance and IBD research explain when labs and dietitian visits matter. DRI tables define population reference ranges; your team personalizes targets.
