Plant-Based Diet & Eye Health: Retinal Protection
A plant-based diet may safeguard your eyes! New research indicates a healthful plant-based diet is linked to thicker retinal sublayers, hinting at neuroprotective benefits for retinal ganglion cells.This study, published in The Journal of Nutrition, Health and Aging, observed associations between diet and retinal health in over 13,000 participants. The Healthful Plant-Based Diet Index, focusing on whole grains, fruits, and vegetables, showed the strongest connection, notably in women and younger adults. Researchers suggest this diet’s protective effects could be linked to cholesterol levels and hormonal differences.

Plant-Based diet May Benefit Retinal Health, Study Suggests
Adhering to a plant-based diet, while not strictly vegetarian, may contribute to healthier retinal ganglion cells and potentially reduce early neurodegeneration detectable via OCT, research indicates. The findings appeared in The Journal of Nutrition,Health and Aging.
Qian Zhu, of Shanghai Jiao Tong University School of Medicine, and colleagues noted that retinal sublayer thickness is linked to ophthalmic conditions like glaucoma, as well as neurodegenerative diseases such as multiple sclerosis, Parkinson’s, and Alzheimer’s.
The researchers analyzed data from 13,993 participants in the UK Biobank, assessing their diets and conducting OCT measurements. they examined the relationships between retinal sublayer measurements and four dietary patterns: the Alternate Mediterranean Diet, the Anti-Empirical Dietary Inflammation Index, the Alternate Healthy Eating Index-2010, and the Healthful Plant-Based Diet Index.
Only the Healthful Plant-based Diet Index showed a consistent association with retinal sublayer thickness. This index considers intake of whole grains,fruits,vegetables,and “moderate healthy animal food,” according to the researchers.
Notable associations were found between higher scores on the Healthful Plant-Based Diet index and the thickness of several retinal sublayers, including the central retinal macular layer (P = .001) and the macular ganglion cell complex (P = .025).
Cholesterol levels appeared to mediate the relationship between the Healthful Plant-Based Diet Index and the thickness of certain retinal layers.The association between the diet score and retinal layer thickness was more pronounced in women and younger individuals, the researchers reported.
Zhu and colleagues suggest that hormonal differences and age-related retinal changes may explain the variations observed between sexes and age groups.
“Potential reasons for this variation could include differences in hormonal profiles, lifestyle factors or biological responses to diet between sexes,” they wrote. “As an example, estrogen in females has been shown to have protective effects on neural tissues, which might interact with dietary factors differently compared to males.”
the study supports the potential neuroprotective benefits of a healthful plant-based diet for retinal ganglion cell health and related processes. Further research is needed to confirm these findings,the researchers said.
What’s next
Additional studies are needed to explore the potential neuroprotective effects of the Healthful Plant-Based Diet Index and to determine the specific mechanisms by which diet impacts retinal health.
