Samsung's new Antioxidant Index feature on the Galaxy Watch 8, designed to estimate fruit and vegetable intake by measuring carotenoid levels in the skin, has been humorously challenged. A reporter at The Verge discovered that a Cheez-It registered as having antioxidants, suggesting the feature's accuracy may need refinement. The watch uses LEDs to detect carotenoids, aiming to help users meet the recommended daily intake of 400g of fruits and vegetables. This incident raises questions about the reliability of using wearable technology for dietary assessments.
