RESEARCH EVIDENCE FOR HYPOGLYCEMIA
By Jurriaan Plesman, BA(Psych), Post Grad Dip Clin Nutr
Below is just a small sample of the research carried out on topics under major headings in alphabetical order which has a bearing on hypoglycemia and Clinical Nutrition. It should also be remembered that hypoglycemia is one aspect of a much wider cluster of symptoms relating to degenerative diseases in general. Thus the net may be cast wide. Because hypoglycemia shares with diabetes “insulin resistance”, much of the research findings concerning diabetes applies equally to hypoglycemia, but the reader should keep in mind the differences between the two, when assessing the data. The under-mentioned references will be updated from time to time. You can search topics in alphabetical order or finding a term by means of “FIND”. [Ctrl+F+”Term”]
"The human brain uses glucose as a primary fuel; insulin secreted by the pancreas cross the blood-brain barrier (BBB), reaching neurons and glial cells, and exerts a region-specific effect on glucose metabolism. Glucose homeostasis is critical for energy generation, neuronal maintenance, neurogenesis, neurotransmitter regulation, cell survival and synaptic plasticity. It also plays a key role in cognitive function. In an insulin resistance condition, there is a reduced sensitivity to insulin resulting in hyperinsulinemia; this condition persists for several years before becoming full-blown diabetes. Toxic levels of insulin negatively influence neuronal function and survival, and elevation of peripheral insulin concentration acutely increases its cerebrospinal fluid (CSF) concentration. Peripheral hyperinsulinemia correlates with an abnormal removal of the amyloid beta peptide (Abeta) and an increase of tau hyperphosphorylation as a result of augmented cdk5 and GSK3beta activities. This leads to cellular cascades that trigger a neurodegenerative phenotype and decline in cognitive function."
“Results suggest that glucose ingestion may affect in vitro measures of cellular immunity by increasing serum insulin, which complexes with mitogens for binding sites on lymphocytes”.
