From the Research

Red 40 (Allura Red) is generally recognized as safe for consumption by regulatory agencies, but individuals with pre-existing allergies or sensitivities should exercise caution. The acceptable daily intake is up to 7 mg per kilogram of body weight per day. While most people can consume Red 40 without issues, some individuals may experience allergic reactions or sensitivity, particularly those with existing allergies or sensitivities to other substances. Children with ADHD may want to limit consumption, as some observational studies suggest a possible link between artificial food dyes and hyperactivity in sensitive children, though evidence remains inconclusive 1, 2, 3. Red 40 has undergone extensive safety testing, and the amounts typically found in foods and beverages are well below established safety thresholds. If you suspect sensitivity to Red 40, consider monitoring your reaction after consuming foods containing this dye and consult a healthcare provider if you experience adverse effects. Some individuals may be at a higher risk of anaphylaxis, a life-threatening systemic reaction, which can be triggered by various allergens, including food dyes like Red 40 1. However, the current evidence does not specifically link Red 40 to an increased risk of anaphylaxis or other severe reactions in the general population. It is essential to note that the provided studies do not directly address the safety of Red 40, but rather discuss anaphylaxis, urticaria, and other allergic reactions in general 1, 2, 4, 3. Therefore, it is crucial to prioritize caution and monitor for any adverse reactions when consuming Red 40, especially in individuals with a history of allergies or sensitivities.
