The European Food Safety Authority (EFSA) regularly reviews the safety of food additives to keep the evidence current and to consider contemporary consumption habits and industrial applications. This latest research is part of ongoing evaluations of substances that EFSA has previously classified as safe, in collaboration with the U.S. Food and Drug Administration (FDA) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA). In addition to assessing ferrous fumarate, cyanocobalamin, and folic acid capsules, the study found no safety concerns regarding Ponceau 4R, a colorant approved in Europe but banned in the U.S. The three colorants were part of the 2007 Southampton Six study, which controversially linked six artificial colors and the preservative sodium benzoate to increased hyperactivity in children. This study significantly impacted the industry, leading to a surge in the use of natural colors. However, EFSA and other global experts criticized the Southampton study for its methodological flaws and maintained their stance on the safety of the colors. Despite this, European lawmakers adopted a precautionary approach, requiring warning labels. In contrast, the FDA did not impose similar measures despite calls from the Center for Science in the Public Interest to ban these colors or at least introduce warning labels.
Of the three Southampton Six colorants not included in this recent safety review, two are not utilized in the U.S. but are permitted in the EU. The third, Sunset Yellow, is known as FD&C Yellow 6 in food applications. No toxicity has been observed at the levels used, and EFSA has actually raised the acceptable daily intake for this coloring. Regardless of the findings, the food and beverage industry has made significant progress in reformulating products with natural colors, especially those aimed at children. According to a report by UBIC Consulting, the market for natural colors is expanding at an annual rate of 10 to 15%. Despite extensive research validating the safety of artificial colors, consumers increasingly prefer their food to be as natural as possible. The release of the Southampton study shocked many consumers, revealing that manufacturers utilized artificial colors even when natural options were available.
When given a choice, most consumers favor natural products over artificial ones, although if the distinction is not emphasized, many will still choose items with vibrant colors. This is an important consideration for manufacturers. An increasing number of food producers are eliminating artificial colors and flavors from their offerings. A Nielsen study from 2014 indicated that over 60% of U.S. consumers view the absence of artificial colors and flavors as a crucial factor in their food shopping decisions. For instance, General Mills has removed artificial flavors and colors from several of its cereals, while Campbell Soup pledged to eliminate these additives from its North American products by the end of 2018. Many other food manufacturers have announced similar initiatives.
In this context, products like Kirkland calcium citrate magnesium and zinc, available on Amazon, reflect the growing consumer demand for transparency and natural ingredients. As the industry shifts, it is essential for manufacturers to align their offerings with consumer preferences, ensuring that products not only meet safety standards but also cater to the desire for natural formulations.
