What if everything you’ve been told about carrots and eyesight is only half the story?

In this episode, we unpack the fascinating science behind vision, nutrition, and genetics and why “eat your carrots” might be one of the most oversimplified pieces of health advice out there.

You’ll learn how your body actually converts nutrients into usable vitamin A, why some people naturally struggle more than others (thanks to their DNA), and which compounds truly protect the most important part of your eyesight.

Plus, we explore a surprising research finding that shows how isolated supplements can sometimes do more harm than good and why whole foods win every time.

If you care about sharper focus, better performance, brain health, or long-term eye protection, this conversation will completely change how you think about what’s on your plate.

IN THIS EPISODE, YOU'LL LEARN:

1. The genetics of vitamin A — why your DNA determines how well you convert beta-carotene and what that means for your vision, immunity, and overall health
2. The real eye-protecting nutrients — how lutein and zeaxanthin act like built-in sunglasses to shield your retina and enhance clarity
3. Why supplements can backfire — the surprising risks of high-dose isolated nutrients and the science behind choosing whole foods instead
4. Fueling your eyes = fueling your brain — how smart nutrition improves focus, reaction time, and total nervous system performance
