Key Points

Vitamin E & Parkinson's Disease

1. High Vitamin E = Less Parkinson's Disease Risk

Those who have a lot of Vitamin E in their diet also have a significantly lower risk of developing Parkinson's Disease.

2. Vitamin E Rich Foods

Legumes, including peas and chickpeas, have a particularly strong protective effect against Parkinson's Diseases

3. Prevention, Not Cure

However, as far as we know, this effect only applies to preventing Parkinson's Disease, not curing it.

Study 1

Vitamin E & Parkinson's Disease Risk
One study found that those who ate more food with Vitamin E had a significantly lower risk of Parkinson's Disease

Eating a diet rich in vitamin E was associated with a reduction in Parkinson's Disease risk, 0.68 (95% CI, 0.49 to 0.93), compared to those who ate the least Vitamin E. Supplements did not decrease risk. Similar, nuts, a food high in Vitamin E, also decreased risk of Parkinson's Disease: "for ≥5/week vs <1/month, pooled RR, 0.57; 95% CI, 0.34 to 0.95"

Our Take

This study suggests that a diet rich in Vitamin E may protect against Parkinson's Disease. However, taking supplements themselves may not help.

Data Source

"Use of vitamin supplements and high intake of carotenoids do not appear to reduce the risk of PD. The reduction in risk of PD associated with high dietary vitamin E intake suggests that other constituents of foods rich in vitamin E may be protective. "

Study 2

Legumes, Vitamin E, and Parkinson's Disease
Another study further supports the argument that Vitamin E may be beneficial for Parkinson's Disease prevention. Eating lots of legumes, which include foods such as lentils, peas, and chickpeas, may help prevent Parkinson's Disease.

A Case-Control study found that those who ate lots of legumes, including lentils and peas, had a significantly lower risk of developing Parkinson's Disease: adjusted OR = 0.27, 95% CI 0.09 to 0.78.

Our Take

This study suggested that eating lots of Legumes, including peas and lentils, correlated with a significantly lower risk of Parkinson's Disease. While the study doesn't specifically find benefits for Vitamin E, the high Vitamin E content of these foods supports the link between Vitamin E and Parkinson's Disease.

Data Source

"Though consistent with prior reports of PD protection afforded by legumes, and with speculation on the possible benefits of dietary or supplemental vitamin E in preventing PD, these preliminary data do not conclusively document a beneficial effect of dietary vitamin E on PD occurrence."

Study 3

A meta-analysis confirms this relationship. They analyzed 8 studies and determined that consuming vitamin E in your diet correlates with a significant reduction in your risk of developing Parkinson's Disease.

A meta-analysis found that those who ate lots of Vitamin E also had a lower risk of Parkinson's Disease. This was found for both moderate intake, "relative risk 0·81, 95% CI 0·67–0·98", and high intake: 0·78, 0·57–1·06

Data Source

"We conclude that dietary vitamin E may have a neuroprotective effect attenuating the risk of PD. These results require confirmation in randomized controlled trials."

Vitamin E Benefits

"The body also needs vitamin E to help keep the immune system strong against viruses and bacteria. Vitamin E is also important in the formation of red blood cells. It helps the body use vitamin K. It also helps widen blood vessels and keep blood from clotting inside them."

Risk Factors for Parkinson's Disease

"Most experts agree that PD is caused by a combination of genetic and environmental factors (chemicals, toxins, head trauma). The interactions between genes and the environment can be quite complex. Some environmental exposures may lower the risk of PD, while others may increase it. "
