If I were to believe the Samsung Galaxy Watch 8, I don\u2019t eat enough fruits and vegetables.<\/p>\n

Normally, smartwatches don\u2019t make judgments about your nutritional intake. But this year, Samsung introduced a new experimental feature called Antioxidant Index. Using blue, yellow, and infrared LEDs, the watch\u2019s sensor can pick up carotenoid levels in your skin. (Carotenoids are a type of antioxidant that give fruits and veg their yellow, orange, or red hues.) You stick your thumb on the sensor, press, and in 10 seconds, you get an estimate of whether you\u2019re meeting the recommended amount of 400g of fruits and veggies per day.<\/p>\n

I wasn\u2019t expecting the Galaxy Watch 8 to say I was the Queen of Plants. I\u2019ve been known to pooh-pooh a side salad in favor of fries with my burgers. But it was kind of rude when two weeks ago at Unpacked, I demoed the feature and got a dismal score of 37. This was after I\u2019d just had a vegetarian July 4th, replete with zucchini, radishes, corn, cabbage, tomatoes, salad, and more peaches than I knew how to digest.<\/p>\n

It was even ruder when this morning; it said I had a \u201cvery low\u201d antioxidant score of 48. This, after eating my customary breakfast that includes a serving of fruit, coffee, and a green juice protein smoothie \u2014 all rich in antioxidants.<\/p>\n

The old me would\u2019ve tossed the Galaxy Watch 8 with an indignant huff. The new, evolved me decided to test this sensor on as many brightly colored things as I could get my thumbs on.<\/p>\n

\"Close<\/a><\/p>\n

I colored my thumb with a yellow-orange Tombow marker. It gave me a score of 100. <\/p>\n

First was a tangerine peel. As expected, it got a score of 100. The same was true of a peach slice, a tangerine section, and a strawberry from my lunch and breakfast, respectively. I had less success with a blackberry. Despite having the highest carotenoid levels<\/a> of any berry, the berry scored a dismal 37. At this point, I thought I was on to something. All the red, yellow, and orange fruits had passed with flying colors, yet a carotenoid-rich blackberry failed? Perhaps the Galaxy Watch 8 was more colorist than accurate.<\/p>\n

I colored my thumb with a yellow-orange marker. Wouldn\u2019t you know it? My Antioxidant Index shot up to 100. Next, I colored it with a blue marker. My score dropped to zero. Unfortunately, my color-based hypothesis was foiled by a piece of roasted broccoli. It, too, scored 100 and is, in fact, rich in carotenoids.<\/p>\n

Perhaps the blackberry had failed because, when pressed against the sensor, it exploded in a mess of purple juice that was subsequently difficult to clean from the watch. Perhaps I was deficient in my antioxidant consumption. Or so I thought, until the Cheez-It.<\/p>\n

\"the<\/a><\/p>\n

But it\u2019s not all orange and yellow foods! Broccoli, which is high in carotenoids, also got a perfect score.<\/p>\n

If you\u2019ve never had a Cheez-It, it is a delightfully cheesy, crispy cracker, and most importantly, it is orange. The Cheez-It scored a near-perfect 99. Surely, a CHEESE cracker is not a paragon of antioxidant content. A quick Google search humbled me. Cheddar, the predominant cheese in Cheez-Its, actually does contain carotenoids<\/a>. That\u2019s actually why it\u2019s orange. Upon this discovery, I had to lie down and stare at my ceiling.<\/p>\n

I asked Samsung whether the sensor detects carotenoids based solely on pigments, or if there\u2019s some other factor at play. Jeffrey Kim, senior product manager at Samsung Electronics America, tells The Verge that the watch\u2019s sensor measures \u201cabsorption levels in the blue-green spectrum, which complements the yellow-orange range to estimate the amount of skin carotenoids\u201d to determine your antioxidant level. Makeup or dyes applied to the skin, Kim says, can disrupt signal measurement and recommended I wash and dry my hands before readings.<\/p>\n

After some rest and reflection, the ghost of my common sense returned to me. It ultimately doesn\u2019t matter whether I meet Samsung\u2019s measure of \u201cenough\u201d fruits and vegetables \u2014 even if it is informed by the World Health Organization\u2019s recommendations. What matters is that I make a concerted effort to include a variety of colorful fruits and veggies on my plate more often than not. If I\u2019m deficient in a vitamin, it\u2019ll likely show up at my next doctor\u2019s appointment.<\/p>\n

Features like this aren\u2019t meant to make you spiral about whether you\u2019re meeting some arbitrary standard. Even if a bunch of science went into developing detection algorithms using high-tech sensors, there\u2019s always going to be errors and room for misinterpretation. This seems obvious, but it\u2019s easy to get sucked into the quantified rat race toward perfection. If tracking a specific metric makes you feel worse about yourself, you\u2019re allowed to take a break from it \u2014 or even decide it\u2019s not worth paying attention to. None of this is meant to be taken that seriously.<\/p>\n

Rather than obsess too hard over a new metric, the best takeaway from my time with the Antioxidant Index has been discovering that I enjoy peaches with waffles and tangerines as snacks. That, and Cheez-Its have antioxidants and from this day forth shall be considered a healthful part of my diet.<\/p>\n
