Nutrition Science

The science of how food fuels the human body — from calorie balance and macronutrient ratios to glycemic response, vitamin bioavailability, and hydration dynamics.

Nutrition science bridges biochemistry and everyday life. Every meal triggers a cascade of metabolic processes — glucose entering the bloodstream, amino acids rebuilding muscle, fatty acids fueling mitochondria. Yet most dietary advice oversimplifies these elegant systems into fads and slogans.

These simulations let you explore the actual mechanisms behind nutrition. Calculate your basal metabolic rate and see how calorie balance drives weight change. Optimize macronutrient ratios for different goals. Watch how glycemic index affects blood sugar curves. Discover why some vitamins need fat for absorption. Model hydration and electrolyte equilibrium in real time.
