Key Takeaways

  • Eye health starts in your kitchen
  • The retina is highly metabolic and creates a lot of oxidative stress, so it needs steady antioxidant support from foods to stay healthy over time.
  • Carrots are great, sweet potatoes might be better
  • Both are rich in beta carotene that your body converts to vitamin A so your eyes can interpret light, but sweet potatoes often contain even more beta carotene per serving.
  • Leafy greens, vitamin C, omega 3s, vitamin E, and zinc are eye health power players
  • These nutrients support the macula, act like natural blue light filters, and help reduce risk for cataracts, macular degeneration, diabetic retinopathy, and dry eye disease.
  • Food first, then supplements if needed
  • Omega 3s and other nutrients work best as part of a healthy diet and any supplements should be discussed with a healthcare provider because more is not always better.
