1 . That artificial food dyes (染料) are unhealthy is not news. Some are known to cause hyperactivity (多动症) in some children, affecting their ability to learn. But regulatory agencies (监管机构) around the world don’t necessarily agree on which food dyes are a problem, or why. That may soon change. A 2021 peer-reviewed report by California’s Office of Environmental Health Hazard Assessment concluded that artificial food dyes “cause or worsen neurobehavioral (神经行为的) problems in some children” and that the current levels that are regarded safe for consumption by the federal government are too high.
California is now considering requiring warning labels on food products and dietary supplements containing the seven most commonly used artificial dyes. The warning label requirement would put California on par with the European Union, which since 2010 has required food products containing certain artificial food dyes to carry warning labels about their negative effect on activity and attention in children.
Artificial dyes are used in foods for one reason: to make products look prettier. Bright colors make candies appealing, especially to kids. But dyes are also in chocolate cake mixes, salad dressings and other products that don’t seem to cry out for a color boost.
In Europe, it was the 2010 label lawmaking that triggered (引发) companies’ decisions to reformulate. “If you’re a company, you do not want to put a warning label on your product.” says Lefferts, an environmental health consultant. Warning labels are why European Starburst Fruit Chews are now colored with natural products, not the artificial dyes that brighten their North American counterparts (同类商品).
Given that artificial food dyes are used far more than needed, we need to be more cautious. After all, we don’t dye fresh fruits and vegetables, but we do dye candy and sprinkles, points out Joe Schwarcz, a chemistry professor at McGill University in Montreal. “The foods in which you find food dyes are foods that are poor in nutrition,” he says. “If you limit foods that contain food dyes, you automatically make your diet better.”

Katie was exceptionally small. We were in the fifth grade, but she was as short as a third grader. Although her body was small, Katie was big at heart. She had a sharp mind, too. Sometimes she got her share of teasing, but Katie knew how to handle it. All the kids who knew Katie liked her a lot.
Katie loved helping others in the class, so whenever someone was stuck on the computer he always called her for help and advice. Katie loved jokes and she always had a joke that would cheer someone up whenever he was down. She was truly the most kind and generous friend anyone could ask for.
But the other day she was in big trouble. She was such a sweet girl; a third-grade teacher always dreamed of having a classroom filled with students like Katie. She was never ever a discipline(纪律)problem. I just couldn’t imagine why she had made her parents so angry.
It seemed that Katie had been running up(积欠)sizable charges in the lunchroom. Her parents explained that Katie brought a great homemade lunch each day, and there was no reason for her to buy school lunch. They assumed a sit-down with Katie would solve the problem, but failed. So they asked me to help them get to the bottom of this situation.
So the next day, I asked Katie to my office. “Why are you charging(记账)lunches, Katie? What happens to your homemade lunch?” I asked. “I lose it,” She responded. I leaned back in my chair and said, “I don’t believe you, Katie.” She didn’t care. “Is someone stealing your lunch, Katie?” I took a new track. “No. I just lose it,” she said. Well, there was nothing else I could do.

The problem was still unsolved the next week until I noticed a boy in the school canteen.
