1. Look: when choosing a disposable cup, don't just look at the color of the paper cup. Don't think the whiter the color, the healthier. Some cup makers have added a lot of fluorescent brighteners to make the cups look whiter. Once these harmful substances enter the human body, they will become potential carcinogens. Experts suggest that when choosing paper cups, the public should first take photos under the light. If the cup is blue under the fluorescent lamp, the fluorescent agent exceeds the standard. Consumers should use it with care.
