What's in your food? Tech will tell!
People are getting more interested in what they're eating, but reading a food label will tell you only so much. Some foods -- fresh fruits and vegetables, for example -- don't have ingredient labels.
In a perfect world, food labels would tell you unambiguously and transparently what's inside the package -- what you're really eating. Unfortunately, today's food labels tell only part of the story.
The truth is that there are some ingredients that food makers are not required to list on labels. In other cases, the wording is ambiguous to the point of being meaningless. For example, labels may say "natural color" or "vegetable oil" or "natural flavor." But they don't tell you whether that color comes from a flower or a beetle, or whether the oil is sunflower oil or palm oil (the latter a culprit in deforestation). And nobody knows what "natural flavor" means.
