Scientists have designed a way to precisely monitor the food we eat using a sensor on our tooth. No longer will we be able to get away with that bag of chips when no one's looking.
The links between diet and health are deep and complex. In their simplest terms, we know that we should eat more fresh food and much less processed salty, fatty, sugary, and delicious food.
However, in the real world, there are plenty of shades of gray in-between.
Because scientists now know that diet is a very important factor in health, getting to grips with what we eat, how much we eat, and when we eat it is of growing importance.
