Polyphenols, homocysteine, Parkinson’s disease and Alzheimer’s disease

High homocysteine levels indicate the transsulfuration pathway (homocysteine to L-cysteine) is dysregulated. Taurine is synthesized from L-cysteine. Taurine is needed to form various bile acids. Bile acids are needed for fat absorption.

Polyphenols can increase beta-oxidation which can lead to serious difficulties if there are difficulties in the metabolism of fatty acids which are likely if there are high homocysteine levels.

Many illnesses for which polyphenols have been postulated to be treatments are associated with high levels of homocysteine, however, where there are high homocysteine levels there could be difficulties in fatty acid metabolism. Increasing levels of polyphenols, which increase beta-oxidation, would be contradicted where there are difficulties in fatty acid metabolism.

Polyphenol supplements are frequently suggested as treatments for Alzheimer’s disease and Parkinson’s disease, however, both Alzheimer’s disease and Parkinson’s disease are associated with high homocyteine levels whereby there could be difficulties in fatty acid metabolism. Polyphenol supplements could worsen Alzheimer’s disease and Parkinson’s disease. In the treatment of Alzheimer’s disease polyphenols have been full of promise but have failed to deliver effective treatments.

Caffeine pills have nowhere near the same effect as coffee. There must be more to the effects of coffee than caffeine and that something more is the polyphenol contents of coffee and the effect of those polyphenols on beta-oxidation.
