High intake of cholesterol shown to actually repair damaged brain

(NaturalNews) Including high-cholesterol foods as part of a healthy diet may not be the poor dietary choice we have all been told it is, suggests a new study published in the journal Nature Medicine. It turns out that cholesterol actually helps increase production of an important component of the nervous system that facilitates proper nerve cell communication, and prevents the onset of brain diseases such as Parkinson's and Alzheimer's disease.
The study focused specifically on patients with a condition known as Pelizaeus-Merzbacher disease (PMD), in which nerve cells are unable to properly manufacture protective myelin sheaths. It is these myelin sheaths, which are composed of lipid fats and proteins, that allow nerves to communicate and send appropriate electrical signals that trigger movement and cognition, and that protect nerves from damage.
Cholesterol, which is commonly dismissed as harmful and something that people should avoid, actually contributes to producing and maintaining myelin sheaths. Without it, as evidenced by the recent studies, individuals with PMD -- and potentially all individuals -- are at a higher risk of developing cognitive illness and brain degradation. And particularly those with PMD, low-cholesterol diets are almost sure to leave them exceptionally prone to nerve damage.
"This six-week-long cholesterol treatment delayed the decline in motor coordination," wrote the scientists in their report. Researchers from the Max Planck Institute of Experimental Medicine in Germany fed a group of mice with PMD a high-cholesterol diet for six weeks, as well as another group of PMD mice a low-cholesterol diet. Those on the high-cholesterol diet stopped experiencing cognitive decline, while the low-cholesterol mice continued to get worse.
