Regarding the effect of protein in the diet. The active molecule in Sinemet is very similar to the amino acid tyrosine. Amino acids linked together form proteins. When dietary protein and Sinemet are present together in the small intestine the uptake into the bloodstream uses the same "conduit". Thus dietary protein can/will slow the uptake of Sinemet relative to its uptake when no other protein is present. Vegetable protein sources are generally not as high in protein content as animal sources and will not compete the Sinemet as much. One suggestion is to eat most of ones dietary protein in the evening prior to bed. This fulfills the dietary need for protein and permits Sinemet uptake during the day with little protein competition.
