Kohlenhydratreiche Ernährung als Wegbereiter für Alzheimer... weniger Kohlenhydrate und mehr Fett und Cholesterin als vorbeugende Maßnahme... klingt doch sehr danach, als würde eine Paleo-Ernährung ziemlich genau in die richtige Richtung weisen, sollten die wissenschaftlichen Erkenntnisse sich weiter erhärten.

Nutrition and Alzheimer's disease: The detrimental role of a high carbohydrate diet
Zitat:
In this paper, we have highlighted that AD may also be caused by a deficiency in the supply chain of cholesterol, fats, and antioxidants to the brain. We have provided much evidence of the importance of these nutrients to brain function, and have shown that AD patients are deficient in cholesterol and fats in the cerebral spinal fluid. We suggest that a diet high in high-glycemic index carbohydrates, particularly fructose, and relatively low in fats and cholesterol, leads to a destructive process that begins with glycation damage to blood serum lipid supply as well as to proteins important to the metabolism of astrocytes. The impairment of astrocytes is accelerated by the excess
energy requirements associated with increased cholesterol synthesis in the absence of a sufficient supply from the bloodstream. Neurons begin to suffer damage as well, once the astrocytes can no longer supply adequate amounts of cholesterol, fats and antioxidants.
(...)
Simple dietary modification, towards fewer highly-processed
carbohydrates and relatively more fats and cholesterol, is likely a
protective measure against Alzheimer's disease.
ferner:
"A ketogenic diet has been found to be therapeutic in AD patients
. It involves an extremely high fat diet, with up to 88% of
calories derived from fats. This benefit may be likely due in part to the
bioavailability of a plentiful supply of fats to repair damaged membranes."

Interessant auch die These, dass es sich bei Alzheimer um eine dritte Form von Diabetes handeln könnte:
