Adding more lycopene-rich foods to the diet might help reduce the symptoms of Parkinson’s disease, according to a study on animals from Annamalai University in India. Lycopene was supplemented in doses of 5, 10, and 20 milligrams/kg body weight/day in the diets of animals with Parkinson’s. Results showed lycopene protected dopamine receptor sites in the animals’ brains in a dose-dependent fashion. It also lowered oxidative stress and improved motor abnormalities. The researchers conclude that, “…lycopene…offers promise as a strategy in the treatment of this neurodegenerative disease.”
