People are scared of what they don't understand, and they no longer trust "experts" and "scientists". I spent my working life in the food industry, supplying additives to food and drink manufacturers. The level of mistrust in the general population is astounding. "E" numbers are thought to be harmful when all they are is a unifying code system, which embraces many different categories, including some essentials like vitamin C. Poor parenting is blamed upon hyperactivity which is then blamed on food colours! All are urban myths dreamed up by people wanting to sell books or with political motives. Even some doctors believe this nonesense which is backed up by some long discredited "research".
