One of many few Galaxy Watch 8 exclusives is its antioxidant index, which measures vitamins via your pores and skin to find out whether or not you are consuming healthily. I took it personally when Samsung estimated that I had “Low” antioxidants, so I spent the previous week consuming as healthily as attainable to see if it made a distinction.
Samsung’s multicolored well being sensors search for carotenoids, the pigment that offers fruits and veggies their shiny pink, orange, or yellow coloring; as soon as in your physique, they counterbalance the “oxidative stress” generated from poor life-style habits like smoking, ingesting, overeating, and stress. Therefore the title “antioxidants.”
Usually talking, the antioxidant index is meant to find out whether or not you are consuming your WHO-recommended 400g of fruit and veggies per day. For health-conscious people who dislike logging their meals day by day, the Galaxy Watch 8 gives worthwhile context.
However since I believed I was consuming healthily sufficient, I made a decision to cram carotenoid-rich meals into my eating regimen for per week to see whether or not Samsung would be capable of detect the adjustments correctly.
How the Antioxidant Index rating works on the Galaxy Watch 8
Your physique shops carotenoids within the pores and skin, the place the Galaxy Watch 8’s optical sensors can spot and measure them. Samsung advised TechRadar that your wrist has too many capillaries, so your blood confuses the outcomes; urgent your thumb towards the sensor will “push away all of the blood” and make it simpler to verify your carotenoid ranges.
Carotenoids are only one kind of antioxidant, however their pigmentation permits Samsung to detect them. We have emailed Samsung to ask if it would finally observe different antioxidants, however for now, carotenoids are one of the best estimate to verify non-invasively in case your physique has different wholesome nutritional vitamins and vitamins.
So, what meals have carotenoids? Samsung suggests root greens (carrots, candy potatoes), leafy greens (spinach, kale), citrus fruits (oranges, mangoes), tomatoes, and bell peppers. Different carotenoid-rich meals embrace pumpkin, squash, cantaloupe, and corn; most pink, orange, and yellow produce will possible have some.
Samsung used information from medical trials at Samsung Seoul Hospital to find out the “correlation between fruit and vegetable consumption and the buildup of carotenoids within the pores and skin.” Enough antioxidant ranges get a rating of 75–100. Folks with “Low” scores (50–75) devour 50–99% of the beneficial day by day quantity, so a couple of 2% enhance per level. Very Low (0–49) is “lower than 50%.”
Samsung additionally warns that your rating might fall throughout “durations of extreme stress or when ingesting or smoking,” so it is about life-style as a lot as diet.
The corporate says it could change the factors with “future medical outcomes,” however the gist is that you really want a rating of 75 to match beneficial ranges. Every little thing above that’s simply gravy, whereas decrease scores go away you weak to “cell injury, extreme growing older, irritation, worsening eyesight, and persistent ailments equivalent to most cancers” over time.
Elevating my Antioxidant Index rating on my Galaxy Watch 8
Samsung warns that it might probably take “as much as 2 weeks on your antioxidant index to replicate an elevated consumption of fruit and veggies,” so I knew that consuming a boatload of carotenoids would not immediately stage me up. However I needed to see if there was an apparent affect from a modified eating regimen within the brief time period.
I caught to my regular eating regimen for the primary day, and my studying stayed constant. Beginning on Monday, I raided my grocery retailer for carotenoid-rich fruits and veggies, then spent the subsequent 5 days consuming salads, bell peppers, cantaloupe, and different wholesome produce, nicely above the beneficial 5 servings per day.
My rating did begin to course-correct, however slowly. I regarded into the advantages of uncooked vs. cooked veggies and realized that uncooked greens are excessive in nutritional vitamins and fiber however low in beta-carotenes. You get probably the most carotenoids from cooked greens paired with wholesome fat, like cooking oil.
I am extra of a uncooked veggies man than a stir-fry man, which can be a part of my drawback. So I attempted to include extra cooked veggies, paired with meats or peanut butter, through the ultimate stretch.

I climbed from an antioxidant index rating of 53 (56% of beneficial antioxidants) to 65 (80%) in per week. In principle, another week of wholesome consuming will carry me to my goal rating of 75, on tempo with Samsung’s two-week estimate.
I am unable to quantify how correct Samsung’s antioxidant index is with no blood check, however this expertise did, no less than, present that this sensor is not just a few pseudoscientific guesstimate. It can inform that I am consuming more healthy.
Then again, it feels demoralizing that my antioxidant index rating has stalled out in the previous couple of days, regardless of consuming so healthily.
I might have cheated and brought dietary dietary supplements to lift my rating, however Samsung warns that these can have “dangerous unwanted side effects” and “enhance your threat for most cancers and coronary heart illness,” so that you and I ought to persist with the healthy-eating path.
The principle drawback with Samsung’s antioxidant index
Most Android watches have meals logging of their apps, however I dislike calorie-counting and having to quantify each meal. I do care about maintaining a healthy diet, nevertheless, and solely the Galaxy Watch 8 and Galaxy Watch Extremely have a instrument like this, due to the BioActive sensor. I am glad to have this instrument as a baseline for my well being.
This is the principle difficulty with the antioxidant index: there are extra antioxidants than simply carotenoids. Different varieties, equivalent to flavonoids, polyphenols, and lycopene, are present in a variety of fruits, greens, beans, and teas, they usually all assist take away the “free radical” molecules that contribute to growing older and illness.
Carotenoids are a key indicator of your well being, one which helped me acknowledge a dietary deficiency. Nevertheless, since Samsung can’t observe different non-pigmented antioxidants as simply, your precise “antioxidant rating” could be increased than Samsung can precisely assess with a smartwatch.
However this is not a criticism! It is merely a reminder that you just should not ignore the wholesome meals that do not have carotenoids simply because Samsung would not reward you for consuming them.
