write about artificial food colours the substances used in them and their harmful effects
Answers
Artificial food coloring makes your foods more appealing and desirable. While the safety of these dyes has been called into question, the U.S. Food and Drug Administration maintains that the artificial food coloring currently permitted for use meet strict safety requirements. Consumer advocacy groups and recent scientific research, however, have linked these food dyes to a number of potential health problems, most notably certain types of cancer in animals and attention-deficit disorder and hyperactivity in children.
According to the consumer advocacy group Center for Science in the Public Interest, artificial food coloring and food dyes present many risks to consumers. A report published by the center notes that many commonly used artificial food colors have been found to cause damage to DNA, or genotoxicity, in more studies than they were found to be safe. But the research on artificial food coloring is limited to animal studies, including mice and rats. While bladder tumors and other forms of cancer were linked to certain artificial coloring in these studies, no human trials have found links between cancer and the dyes in humans. The center still contends they are dangerous to consumers and has urged many large manufacturers to discontinue their use.
