US Food and Drug Administration (FDA) is set to decide on a potential ban of certain food dyes following a petition urging a review of the safety of Red 3. After several studies linked them to cancer, food dyes have been under scrutiny for a long time. These artificial colours, like Red 40, Yellow 5 and Yellow 6, are ubiquitous in food items like sodas, candies etc. While the agency has reviewed the safety of Red 3 in food and drugs multiple times, the latest petition calls for another review, reigniting concerns about its continued use."With the holiday season in full swing and sweet treats everywhere, it is alarming that this chemical is still hidden in the foods we and our children consume," wrote US Representative Frank Pallone Jr. (D-NJ), a ranking member of the House Energy and Commerce Committee, in a letter to the FDA. He further argued that there is no justification for Red 3's use in food except to make products more visually appealing, which he believes misleads consumers.Red 3 is used in over 3,000 food products. While the FDA said that this food dye is safe to consume if done correctly, several studies found it to be carcinogenic in animals and has been banned in cosmetics since 1990.Research indicates that food dyes may pose risks to human health, including behavioural changes in children, allergic reactions, and potential carcinogenic effects. Just last year, California banned four food dyes, including Red 3. Robert F Kennedy Jr, Donald Trump’s pick to be the next health secretary during his second presidency, has linked such food dyes to cancer and has been critical of the FDA for allowing certain substances in foods.Here Are Most Common Food Dyes UsedRed No. 3 (Erythrosine): A cherry-red colouring commonly used in candy, popsicles and cake-decorating gels.Red No. 40 (Allura Red): A dark red dye that is used in sports drinks, candy, condiments and cereals.Yellow No. 5 (Tartrazine): A lemon-yellow dye that is found in candy, soft drinks, chips, popcorn and cereals.Yellow No. 6 (Sunset Yellow): An orange-yellow dye that is used in candy, sauces, baked goods and preserved fruits.Blue No. 1 (Brilliant Blue): A greenish-blue dye used in ice cream, canned peas, packaged soups, popsicles and icings.Blue No. 2 (Indigo Carmine): A royal blue dye found in candy, ice cream, cereal and snacks.ALSO READ: Having More Plant Protein Than Animal Protein May Reduce Risk Of Heart DiseaseBesides being cancerous, food dyes have been associated with serious side effects, such as hyperactivity in children, as well as cancer and allergies. The most concerning claim about artificial food dyes is that they cause cancer. Moreover, certain food dyes cause allergic reactions in some people, but if you do not have any symptoms of an allergy, there is no reason to eliminate them from your diet. The claim about food dyes that has the strongest science to back it up is the connection between food dyes and hyperactivity in children.Several studies have found that food dyes increase hyperactivity in children with and without ADHD, although some children seem to be more sensitive than others. If your child has hyperactive or aggressive behaviour, it may be beneficial to remove artificial food dyes from their diet. There is also absolutely no nutritional benefit of food dyes.
