Galaxy Watch Rolls Out a Nutrition Tracker to Monitor Your Fruit and Vegetable Intake

Samsung Galaxy Watch Integrates Nutrition Technology: Carotenoid Index on Your Wrist

Samsung’s Galaxy Watch8 has introduced a new feature called “Antioxidant Index,” which measures the carotenoid levels in the human body. The South Korean electronics giant has become the first company to feature a measurable nutrition index in wearable devices.
The company has reportedly used an advanced technology to miniaturize the sensor technology. The tracking of carotenoid levels in the human body was previously dependent on bulky machines. However, Samsung has managed to transform it into a wearable sensor.

The Science Behind the Antioxidant Index

Carotenoids are the key indicators of fruits and vegetables in the human body; their concentration in the body is basically referred to as carotenoid levels. They are measured in blood, plasma, and tissues. 

After years of research and development, the company finally successfully managed to fit the lab-grade sensor into a smartwatch. This new “Antioxidant Index” feature basically combines multi-wavelength LEDs with a photodetector array to measure precise carotenoid levels. 

Jinyoung Park, a developer at Samsung Electronics, explained that “Our breakthrough was integrating reflectance spectroscopy with LEDs, which allowed us to miniaturize the technology while maintaining a high level of accuracy.”

Additionally, Samsung has also tested the performance of this new wearable technology on different skin types, and the results were accurate in all cases. 

How Does the New Sensor Work?

Carotenoids are colored pigments found in fruits and vegetables; they are present in red, yellow, and green colors. As the human body is unable to create these compounds on its own, these are perfect indicators of the fruit and vegetable intake of an individual.

Most importantly, the carotenoid levels also get affected by the quality of sleep, physical activity, and stress levels, which makes the Antioxidant Index an overall health indicator. The readings measured by the Galaxy Watch8 are categorized into three categories: very low (less than 50%), low (between 50% and 100%),  and optimal (100% or more). 

Samsung Galaxy Watch8’s  "Antioxidant Index" is capable of measuring a user's carotenoid levels in just five seconds. This proposed feature is described as the first measurable nutrition tracking technology on a smartwatch, designed to help users monitor their nutritional health.
