Foods Rich in Vitamin E Lowers the Risk of Alzheimer's and Parkinson's Diseases

Vitamin E is a potent antioxidant which offers a wide array of health benefits. A regular intake of vitamin E is associated with a wide spectrum of advantages including skin improvement, prevention from degenerative disorders such as cardiovascular complications, eyesight problems, etc. An increasing line of researches have confirmed that foods rich in vitamin E have the potentiality to lower the risk for Alzheimer's disease and Parkinson's disease. Now we will reflect over few interesting facts found from different scientific studies concerning the claim.

Alzheimer's Disease and Related Studies

Over 32 million people from United States are affected with Alzheimer's disease. It is diagnosed as the most common form of dementia, usually prevalent among elderly population. At its early stages, Alzheimer's disease progresses very slowly by affecting different segments of brain area responsible for regulating thought, memory, and language. In the due course of time, the condition becomes worse and the affected individuals become unable to identify close ones or forget to accomplish simple tasks like reading or sitting in a chair.

According to the studies conducted by the National Institute of Aging (NIA), foods rich in vitamin E content may aid in protecting individuals against the onset of Alzheimer's disease. The recommended dietary allowance (RDA) in the case of vitamin E estimates as 22 IU on a daily basis. Although vitamin E supplements offer potential health benefits, dosages higher than 2000 IU in a day may heighten the risk of bleeding due to the anticoagulation property of vitamin E. Potential measures need to be taken regarding the possible interactions of other medications.

Researchers are increasingly taking their interest and effort in finding out the effectiveness of foods rich in vitamin E as well as the benefits of other antioxidants in averting or delaying age-related cognitive decline and Alzheimer's disease. No matter what the researchers suggest in recent future, a regular intake of foods rich in vitamin E with fresh fruits and green leafy vegetables can put many health complications at bay. So think.

Parkinson's Disease and Related Studies

Parkinson's disease refers to a health complication during which an individual's nerve cells are serious affected. It is believed that the secretion of dopamine neurotransmitter ends or does not function effectively for the individual suffering from Parkinson's disease. No researches have been yet confirmed the exact causes behind the development of Parkinson's disease. At its worst end, individuals experience extreme difficulty in talking, walking, moving or even performing simple tasks. Till date, there is no cure for Parkinson's disease.

According to Parkinson's Disease Society, foods rich in vitamin E may offer protection to the brain against the development of this disease. However, additional studies suggest that vitamin C does not offer any help in this particular aspect. Reports published in Lancet Medical Journal assert that people depending consistently on foods rich in vitamin E have lower risk for developing Parkinson's disease; however, there is no strong evidence in the support of supplements. However, scientists have not come under single conclusion how vitamin E helps.
