Foodmate is an ergonomic stuff that can read the Sugar and Gluten % in your food.
It shows you the exact % of this substances over the table and with it’s red/green lights warns you about eating or not this food. Previously you have to “teach” it what is the max. percentage that you can/want to eat, easily via USB.
There are a lot of fakes and illogical products in some crowdfunding platforms, but they are not real (read HERE for more info).
Foodmate is still a concept but it is viable with nowadays technology.
