Do lentils contain levodopa?

As far as a know the only foods containing levodopa are macuna puriens and fava beans.

On Monday and yesterday I ate large amounts of red split lentils, about 50gm dried weight in total. I found that I was "on" all day with just one dose in the morning of Stalevo, plus the other non-levodopa drugs I take. Put another way, I went without about 250mg of levodopa without effect.

(Note, I'm not saying this was better than my normal drugs, just that it was an alternative way to give the same effect.)

Today, lentil-free I'm back on my normal drug regime.

Googling around I came up with one reference:

"Determination of levodopa by capillary zone electrophoresis using an acidic phosphate buffer and its application in the analysis of beans."

Zhang, Zhai and Hu write:

"A simple capillary zone electrophoresis method has been developed for the quantification of levodopa in broad bean and lentil."

Unfortunately, I can't get through the pay wall to get to the results, so I can't be sure that the paper above shows that lentils do contain levodopa.
