We know that processed foods are bad for us, and that though they may be tasty, they do not bring us any nutritional benefits. How come we find it so hard to say no to those chips, donuts, and crackers?
We know that processed foods aren’t good for us, but how do our brains react?
Many processed foods — such as potato chips, donuts, crackers, cookies, and fries — have a high content of both (saturated) fat and carbohydrates.
Star Trek fans will be familiar with the tricorder – a device used in the fictional TV series to scan and gather detailed information about places and living things. Now, researchers have brought the technology to the real world, creating a wearable, tricorder-like device that can measure biochemical and electrical signals in the human body simultaneously.
The device – called the “Chem-Phys patch” – measures real-time levels of lactate, a biochemical that serves as an indicator of physical activity, as well as the heart’s electrical activity.
Put simply, the novel technology monitors a person’s fitness levels and heart function at the same time, and it is the first device that can do so.
“One of the overarching goals of our research is to build a wearable tricorder-like device that can measure simultaneously a whole suite of chemical, physical and electrophysiological signals continuously throughout the day,” says co-project leader Patrick Mercier, of the Jacobs School of Engineering at the University of California-San Diego.
