Researchers find nicotine may prevent Parkinson’s

Previous studies have consistently found exposure to tobacco – a member of the Solanaceae ‘nightshade’ family of plants – is associated with reduced relative risk of Parkinson’s disease.

In a study of 490 Washington patients with idiopathic Parkinson’s and 644 controls, researchers found high consumption of Solanaceae vegetables such as potatoes, tomatoes and, in particular, capsicums, appeared protective against the disease, while eating lots of vegetables in general had no such association.
