Treating Parkinson's disease with velvet beans.

0:04.0

I have several videos on foods that may trigger Parkinson's disease,

0:07.5

but how can diet be used in treatment?

0:11.0

This video in the next look at beans for treating this disease. Two centuries have passed since James Parkinson's essay on the shaking palsy,

0:30.4

described a disease characterized by tremor and problems with movement.

0:34.9

Today, treatment options include surgically implanting electrodes into the

0:39.3

brain. There has to be a better way.

0:43.3

We've known since the 1950s that Parkinson's disease is manifested by a dopamine deficiency

0:49.3

in the brain. Well, then, why not eat a dopamine diet? A variety of fruits and vegetables contain the same dopamine made by our brain.

0:58.0

Unfortunately, dopamine can't cross the blood-brain barrier and hence is ineffective as therapy.

1:03.0

However, the dopamine precursor, known as L-dopa or L-dopa,

1:08.0

can get from the blood up into the brain, where it can then be converted

1:12.5

to dopamine within the brain by an enzyme called decarboxylase.

1:16.9

We don't want the Leverdopa to be converted to dopamine outside the brain, because then it can't

1:21.5

get in, so we give people a decarboxylase inhibitor, which itself can't get into the brain, so that keeps

1:28.2

levodopa from prematurely turning into dopamine before it gets into the brain where we need it.

1:34.0

So eating dopamine-rich foods doesn't help, but what if we ate Leva-Dopa-rich foods?

1:39.7

More than 1,500 years before Dr. Parkinson came on the scene, an Indian physician seemed to have

1:46.0

nailed it and even suggested a treatment.

1:49.7

Velvet beans, the plant with the highest amount of al-Dopa.

1:55.3

Huh.

1:57.2

So might there be a way to forestall the epidemic of Parkinson's disease through plant-based remedies, after all?
