Gus raised the issue of bananas and their deteriorating effect on levodopa.
Since I eat more bananas than the average chimp I thought it worth looking into.
I found 3 articles
This refered to one patientt who had a reaction.to levodopa.
This referred to EC Dopryl administered to rats. EC Dopryl is similar to madopar
This referred to Levodopa and bananas / vitamin b6 levodopa/carbadopa were deemed ok.
I concluded banana ok with sinamet but not madopar
however be aware generally of any adverse reaction
