Purpose: To evaluate the risk of PD associated with tea consumption. Material and Methods: We reviewed all observational studies that evaluated the association between PD risk and tea consumption. Only, 12 studies were identified: 11 case-control and 1 cohort. These studies were carried out between 1981 and 2003. The studies represented different populations from 3 continents; North America, Europe and Asia. The 3 studies from Asia were case-control studies of Chinese populations. Results… 
Tea consumption and risk of Parkinson ’ s disease : A meta-analysis
The meta-analysis showed that tea consumption was associated with a reduced risk of developing Parkinson’s disease when case–control studies and prospective cohort trials were considered together and the results of the subgroup analysis suggested that people who drinking more than one cup of non-black tea daily might have a reducedrisk of developing PD.
Non-genetic factors associated with the risk of Parkinson's disease in Iranian patients.
Coffee and tea consumption may exert a protective effect against Parkinson's disease, while evening work and stress may be risk factors for the development of the disease.
Epidemiology of Parkinson's disease
The prevalence and incidence of Parkinson’s disease in Asians will be reviewed and the strength of the association of epidemiological factors with PD will be graded by weighing the evidence for each of these factors.
Epidemiology of Parkinson's disease in South central India-A longitudinal cohort study
PD was found to be more common in males and in patients above the age of 60 with rural habitation in south-central India, where it represents varied geographical, social, economic, cultural ethnicity among rural/urban population.
Association of Tooth Loss with New-Onset Parkinson's Disease: A Nationwide Population-Based Cohort Study
The number of tooth loss was positively related to an increased risk of new-onset Parkinson's disease development and the frequency of tooth brushings and dental clinic visits for any causes as well as competent dental care were negatively related to the development of the disease.
Therapeutic Potential of Polyphenols in Parkinson’s Disease
There is a tremendous momentum to develop newer treatments involving disease modifying, restorative, possibly curative drugs with lesser side effects so as to protect the dying neurons thus preventing further neuronal loss.
Tea Polyphenols in Parkinson's Disease.
Consistent mechanistic data on the neuroprotective and neuroregenerative effects of tea polyphenols indicate that they do not just possess anti-oxidant or anti-chelating properties but may directly interfere with aggregation of the αS protein and modulate intracellular signalling pathways, both in vitro and in animal models.

Tai Chi had the potential to slow down the progression of symptoms of Parkinson's disease and delayed the introduction of levodopa (level of evidence: III).


Diet and Parkinson's disease I
The intake of certain foods may be associated with the development of Parkinson's disease, and the intake of sweet foods may enhance the transport of L-dopa across the blood-brain barrier.
Risk Factors for Parkinson’s Disease: The Leisure World Cohort Study
Several environmental factors that may be related to the development of Parkinson’s disease are suggested and support a multifactorial etiology.
Concerns are raised about generalization of the conclusion previously settled by many cohort and case-control studies that smoking induces debrisoquine 4-hydroxylase, which is responsible for the metabolism of antipsychotic drugs and the detoxification of certain environmental toxins known to cause dopaminergic neural damage in Chinese populations.
A meta‐analysis of coffee drinking, cigarette smoking, and the risk of Parkinson's disease
There is strong epidemiological evidence that smokers and coffee drinkers have a lower risk of Parkinson's disease, and further research is required on the biological mechanisms underlying this potentially protective effect.
Prospective study of caffeine consumption and risk of Parkinson's disease in men and women
A possible protective effect of moderate doses of caffeine on risk of Parkinson's disease is supported, with the lowest risk observed at moderate intakes of coffee/day, or the third quintile of caffeine consumption.
Worldwide occurrence of Parkinson's disease: an updated review.
The actual prevalence variation for PD is probably lower than previously reported in geographically diverse populations and geographic variation is unlikely to be due exclusively to racial factors, and environmental risk factors for PD might differ regionally.
Parkinson's disease risks associated with cigarette smoking, alcohol consumption, and caffeine intake.
Findings are presented regarding associations of PD with smoking, caffeine intake, and alcohol consumption from a case-control study conducted in western Washington State in 1992-2000.
Risk‐factors for Parkinson's disease: case‐control study in the province of Cáceres, Spain
Rural living, well‐water drinking, positive family history for PD and postural tremor, and alcohol‐drinking habit in males were associated to an increased risk for PD, with results regarding exposure to pesticides near to statistical significance.
Cigarette smoking and protection from Parkinson's disease
A protective association of cigarette smoking for Parkinson's disease may constitute an important etiologic clue.
