The European Food Safety Authority (EFSA) periodically reviews the safety of food additives to ensure that the evidence is current and that existing consumption trends and industrial applications are considered. This latest research is part of the ongoing evaluations of additives that the organization 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 Tartrazine and Allura Red 4C, researchers also found no safety concerns regarding Ponceau 4R, which is allowed in Europe but banned in the United States. These three food colorings are part of the Southampton Six study, which in 2007 linked six artificial food colors and sodium benzoate, a preservative, to hyperactivity in children. This revelation caused a significant stir in the industry and propelled the natural colors sector forward. Nonetheless, EFSA and other international experts deemed the study fundamentally flawed and saw no reason to change their stance on the safety of these colors. Despite this, European lawmakers adopted a precautionary stance and required warning labels. The FDA, however, did not impose similar measures, even under pressure from the Center for Science in the Public Interest to prohibit these colors or at least mandate warning labels.
Among the three other colorings from the Southampton Six not included in this recent safety assessment, two are not utilized in the United States, although they are permitted in the EU. The third, Sunset Yellow, is labeled as FD&C Yellow 6 when used in foods, and no toxicity has been identified for the levels at which it is used. In fact, EFSA has even raised the acceptable daily intake for this coloring.
Regardless of the research 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 is expanding at a rate of about 10 to 15% annually. Despite extensive studies affirming the safety of artificial colors, consumer preference leans towards natural ingredients. When the Southampton study was published, many consumers were shocked to learn that manufacturers were using artificial colors when natural alternatives were readily available.
Given the option, most consumers prefer natural products over artificial ones. However, if the difference is not emphasized, many still tend to choose items with more vibrant colors, a consideration that manufacturers should remember. An increasing number of food producers are eliminating artificial colors and flavors from their offerings. A 2014 Nielsen study indicated that over 60% of U.S. consumers consider the absence of artificial colors and flavors an important factor in their food purchasing decisions. General Mills has removed artificial flavors and colors from select 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 the context of health and wellness, products like Citracal with Magnesium are also gaining popularity among consumers looking for natural supplements, which reinforces the trend towards natural ingredients across various food categories. As manufacturers increasingly focus on transparency and natural formulations, the demand for products like Citracal with Magnesium reflects a broader consumer shift towards health-conscious choices.
