All systems ↗Immediate processing
Motility, secretion, digestion, absorption, incretin and pancreatic signals, portal delivery, chylomicron traffic, hepatic substrate handling, and alcohol oxidation.
SYSTEMS / DIGESTIVE · LIVER · NUTRITION
A meal becomes
usable biology.
Trace food from mechanical breakdown and enzymes to intestinal transport, portal delivery, liver processing, lymphatic lipid traffic, microbial fermentation, and systemic use.

INTERACTIVE FLOW ATLAS
Four routes.
Different vehicles.
Carbohydrate and amino acids primarily enter portal blood; most long-chain dietary fat leaves in chylomicrons through lymph. Fiber reaches the colon, while alcohol is absorbed and prioritized for hepatic metabolism.

Each stage separates the transport route from its metabolic consequence.
TRANSCRIPT Narration follows the visible stage text.
Sequence is simplified: processes overlap, anatomy varies, and the amount absorbed or metabolized depends on the food matrix, physiology, medicines, disease, and timing.
QUALITATIVE MEAL SIMULATION
Change the inputs.
Compare the pathways.
The controls reuse the insulin atlas meal dimensions and add alcohol, timing, and meal size. Outputs describe directional pathway pressure only—not glucose, triglyceride, liver-enzyme, intoxication, or calorie predictions.
PATHWAY PRESSURETypical mixed meal · usual interval
Interpretation boundary
These labels do not estimate absorption completeness, blood concentrations, energy balance, intoxication, or health benefit. “Higher” means stronger qualitative involvement relative to this model’s default meal.
ABSORPTION REFERENCE
Site, vehicle,
and dependency.
Absorption is distributed, not assigned to one universal location. Deficiency risk depends on intake, digestion, transport, stores, losses, medicines, disease, and life stage.

TIMESCALE SEPARATION
A meal is not
a chronic state.
Immediate flux and long-term adaptation are shown separately to avoid turning a single exposure into a disease claim.
Repeated context
Glycogen turnover, bowel pattern, epithelial renewal, enzyme adaptation, bile-acid cycling, microbial substrate availability, and changes in habitual intake.
Cumulative adaptation
Nutrient status, microbiome ecology, body composition, metabolic risk, alcohol-related injury, steatosis/fibrosis, and disease emerge from interacting exposures and susceptibility—not one meal.
