A Tricorder To Find Out What’s In Your Food

TellSpec is a new device currently being crowd funded that tells people what’s in their food – just like a Star Trek tricorder. It uses spectrometry to analyze the food it scans to find out if there any unwanted chemicals on food. The device can also scan food to find out how many calories it has.

What is TellSpec?

TellSpec is a three-part system which includes: (1) a spectrometer scanner (2) an algorithm that exists in the cloud; and (3) an easy-to-understand interface on your smart phone. Just aim the scanner at the food and press the button until it beeps. You can scan directly or through plastic or glass. TellSpec analyzes the findings using the algorithm and sends a report to your phone telling you the allergens, chemicals, nutrients, calories, and ingredients in the food. TellSpec is a fast, simple, and easy-to-use way to learn what’s in your food. We need your help to make it smaller and manufacture it as a handheld device.

Measure Food in Exercise, Not Calories

Yesterday we looked at labelling gas nozzles and today here’s good news about a better way to label food. A series of studies add up to the conclusion that if people were aware of how much walking it would take to burn off food they eat less. Calories can be confusing so by telling people how much time walking it can help people understand how much energy they are consuming.

“People who viewed the menu without nutritional information ordered a meal totaling 1,020 calories, on average, significantly more than the average 826 calories ordered by those who viewed menus that included information about walking-distance,” writes Scientific American. People who saw the menu with walking-distance info also ordered less than people who just saw calorie info.
