Fascinating series. Watch it even if you are not overweight. You'll learn a lot. The villain in this piece is fructose, found in table sugar or corn syrup. Of particular interest is part 4 about addiction. It turns out that fructose, like heroin or cocaine, downregulates dopamine receptors in the pleasure center of the brain, the nucleus accumbens causing addiction. It also turns out that the nucleus accumbens is in the basal ganglia in close proximity to the substantia nigra. Is it not possible that receptors there are also downregulated?
It is thought that the dopamine receptors in PD are not destroyed but merely dormant in many cases. If so, could PD be the result of excess sugar consumption? PD did not become prevalent until the industrial revolution when sugar appeared in our diet in large amounts. Perhaps some people have a genetic predisposition to sugar sensitivity in that part of the brain.
