Chinese firm serves up 'smart chopsticks' for food-wary diners

If I carried these chopsticks around with me everywhere, I think I’d die of hunger

I'd like a version to test for actual nutrients.

“Gutter oil” is a particular concern—cooking oil illegally made by reprocessing waste oil or by dredging up leftovers from restaurants and marketing it as new.

I think the above quote sums up for me nicely why I am always a little wary of food products "made in China".

This innovative item is sometime needed.

In Japan, June is rainy season, so　humidity has been high during the season. In the situation, food unfortunately are easy to go bad. Every year, lots of people suffer from the food poisoning due to high humidity.

In such case, the innovative item will play a good role.
