veggie laserPopeye the Sailorman cannot stress enough just how important it is to have your fair share of vegetables in your diet, and exasperated parents over the years did try different methods in making vegetables more appealing, but seemingly to no avail. Here is a tool from the researchers at Yale University and the University of Utah who might help parents monitor the amount of vegetable intake in their scions. Coming in the form of a handheld laser device, all you need to do is point it at the palm on your child for 30 seconds, before dispensing praise or a stern word of warning.

Just how does it work? Well, this technology works on the premise that folks who indulge in diets that have high content of vegetables will develop a slightly yellow skin discoloration, as carotenoids accumulate in the blood. It is possible to measure these carotenoid levels using a well developed technique known as resonance Raman spectroscopy (RRS). This portable laser will carry a blue argon laser that is hooked up to a flexible fiber optic probe, where it has been fine tuned to a specific frequency where carotenoids resonate most strongly, taking around half a minute to measure those levels. All data will be sent to a connected notebook, where it takes another 30 seconds to process it.
