- Pancreatic amylase (starches -> disaccharides)
- Monosaccharides -> liver -> glucose
CHO Digestion/Glucose Conversion Occurs In
- Small intestine (monosaccharides are converted to glucose)
Type 1 vs Type 2 Diabetes
- Type 1: autoimmune destruction of insulin-producing cells (little to no insulin produced)
- Type 2: cells become resistant to insulin (90% of cases)
Postprandial CHO Digestion
