In the quiet negotiation between technology and the body, Samsung's Galaxy Watch 8 introduces a sensor that reads carotenoids stored beneath the skin — pigments accumulated through the eating of fruits and vegetables — offering a non-invasive window into nutritional habits. A reviewer, initially skeptical of a 'Low' reading, spent a week eating deliberately and watched their score climb twelve points, confirming that the watch responds to real change. The feature does not capture the full spectrum of antioxidants, only those visible to light, which is both its honest limitation and a reminder
