Study Notes
- Carbohydrates are the major macronutrient in most human diets.
- Glucose is absorbed into enterocytes using the free energy of the sodium gradient.
- Glycaemic index measures the effect of ingesting a standard amount of carbohydrate on blood glucose.
- Low GI/GL diets have been associated with several benefits.
- Glucose tolerance test measures the response to a glucose load.
- Hyperglycaemia can cause non-enzymatic glycation of proteins, leading to AGE accumulation.
- Glycated haemoglobin gives a good indication of average glycaemia in a patient.
- Type I diabetes mellitus is caused by autoimmune destruction of the pancreatic β cells.
- Type II diabetes mellitus is caused by a combination of insulin resistance and impaired insulin secretion.
- In the fed state, glucose uptake by many tissues.
