Why this page doesn't claim "Carrot works"
Whole foods almost never have RCTs — the evidence sits on the ingredients. So this page does one honest thing: it lists which graded ingredients Carrot contains, how much, and how far that is from the studied dose. It makes no efficacy claim about Carrot itself.
Bottom line: The carrot's beta-carotene converts to vitamin A, with one serving close to the daily requirement and no risk of excess. "Carrots are good for your eyes" only holds for night blindness caused by vitamin A deficiency - for those who aren't deficient, eating more won't improve vision.
