Recent research on Alzheimers disease is revealing that a diet chronically high in carbohydrates combined with low cholesterol is associated with the development of a brain based insulin resistance (now being called Type 3 Diabetes) which can lead to an imbalance in the cellular function and repair mechanisms of the brain.
The brain is extremely active metabolically, and it is in a constant state of maintaining a balance between the destructive aspects of burning sugar for energy and rebuilding its neurons (brain cells) from incoming cholesterol molecules. If blood cholesterol levels fall too low, and blood sugar is chronically high, this delicate balance is upset, and the destruction of the brain cells begins to take the upper hand as oxidative stress increases.
Because the affected brain lacks enough cholesterol for rebuilding its neuronal cell walls, it substitutes beta-amyloid substances instead. This leads to the buildup of the amyloid plaques associated with Alzheimers disease. For more information on this theory, see Alzheimer’s Solved: Condensed Edition by Henry O. Lorin, DMD.
Other Alzheimers disease research has found that cholesterol plays an essential role in the mechanisms of neuronal synaptic function and plasticity.
We have been conned into considering cholesterol as a toxic molecule but it is the complete opposite: cholesterol is vital for health and vitality and as this research shows is especially important for brain health.
