Beyond Carrots: The Gut–Eye–Brain Connection to Prevent Vision Loss

9 hours ago

The Eye Is an Extension of the Brain – Over 50% of the brain’s pathways are dedicated to vision. The retina is neurologic tissue, meaning eye health reflects brain health. Eye exams can reveal early signs of high blood pressure, diabetes, high cholesterol, and even neurodegenerative disease.
Carrots Are Not Enough – While carrots contain beta-carotene (Vitamin A), they are only one piece of the puzzle. Macular carotenoids like lutein and zeaxanthin are critical for protecting against vision loss and can reduce risk by over 40%. Dietary diversity—3–5 cups of colorful plants daily—is essential to nourish the eye’s 200+ cell types.
The Gut Drives Ocular Inflammation – The gut-eye axis is real. Microbiome imbalances and certain pathogens can trigger inflammatory eye conditions like uveitis. Supporting gut health, lowering stress hormones like cortisol, and reducing systemic inflammation are foundational for protecting vision.
