The synthetic dye red 40 has been the subject of controversy over concerns about its potential link to hyperactivity and allergic reactions. Despite being FDA-approved since 1971, some health experts are questioning its safety for consumption.
According to dietitian Caroline Thomason, RD, CDCES, research suggests that children may be sensitive to red 40, with some studies linking it to an increased risk of Attention Deficit/Hyperactivity Disorder (ADHD). The FDA notes that most children have no adverse effects when consuming foods containing color additives, but some evidence suggests that certain children may be sensitive.
While some states, such as California and New York, are considering bans on red 40, the European Union requires products containing the dye to include a health warning label. Canada does not permit its use.
For adults, many nutrition experts argue that current research shows red 40 to be safe in moderation. However, at high concentrations, it may cause reactions. The FDA regulates the use of food dyes and claims that color additives are safe when used in accordance with regulations.
If you’re concerned about red 40 consumption, look for brands that avoid synthetic dyes and opt for natural alternatives. Occasional consumption is unlikely to be a major concern for most people. Instead, focus on a diet rich in whole, minimally processed foods.
