Natuklasan ng kamakailang pananaliksik na nag-aaral ng halos 44,000 lalaki at babae na ang mas mataas na antas ng bitamina c at bitamina E in the diet are associated with lower risk of Parkinson’s Disease1.
Bitamina C and E are antioxidants2. Pinipigilan ng mga antioxidant ang oxidative stress, na dulot ng mataas na reaktibong mga molekula na kilala bilang mga libreng radikal2. Ang oxidative stress ay may iba't ibang pinagmumulan tulad ng sikat ng araw, polusyon sa hangin, usok ng sigarilyo at ehersisyo2. Oxidative stress can cause cell damage (through damage to molecules in the body) and can contribute to many diseases such as cancer, heart disease, diabetes, Alzheimer’s disease, Parkinson’s sakit and even eye diseases2. Samakatuwid, ang mga antioxidant ay maaaring maging kapaki-pakinabang upang maiwasan ang pinsala sa molekular at mapanatili ang kalusugan ng mga selula.
Ang isang kamakailang pag-aaral sa Suweko ay ginalugad ang mga epekto ng ilang mga kadahilanan sa pandiyeta sa saklaw ng pag-unlad ng Karamdaman ni Parkinson (PD) sa halos 44,000 lalaki at babae1. These factors included dietary intake of bitamina C, bitamina E and beta-carotene1. Ang mga intake ng mga tiyak na micronutrients ay inihambing sa saklaw ng PD sa grupo1.
Ang beta-carotene ay walang kaugnayan sa panganib ng PD1. However, intake of bitamina C and E was inversely correlated to the risk of PD1 na nagpapahiwatig na ang mga antioxidant na ito ay nagbigay ng ilang neuroprotective effect na nagpabawas sa saklaw ng PD.
This study may allow the inference that it may be beneficial to increase these bitamina in the diet to reduce risk of PD, but it does not necessarily mean that the association seen was caused by the intake of these bitamina, as people ingesting more of these bitamina might just have healthier diets and lifestyles. It may be the case that there was a causal relationship but this is hard to prove from an association study. There could also be a non-causal relationship; supporting this is the finding from an older study comparing levels of antioxidants in the blood of PD patients which found no evidence that antioxidants contributed to onset or progression of PD3. Lastly, both theories may be true, where bitamina C and E in diet played a minor role. Regardless, the overall message of intaking enough vitamin C (such as through eating oranges and strawberries) and bitamina E (such as through eating nuts and seeds) is probably conducive to good health.
