While food coloring is generally considered safe in small quantities, excessive consumption can lead to negative health effects. Some food dyes have been linked to behavioral problems in children, allergic reactions, and even cancer in animal studies. Red and yellow dyes, in particular, have been associated with hyperactivity and ADHD symptoms in some children. Additionally, artificial food coloring is often found in highly processed, junk foods with low nutritional value, which can contribute to obesity, diabetes, and other health problems. It’s important to consume food coloring in moderation and focus on consuming whole, natural foods as much as possible.
