Blue 1 (Brilliant Blue FCF, E133)

Blue 1, also known as Brilliant Blue FCF, is an artificial food dye commonly used to give a bright blue color to drinks, candies, and processed foods.

How It May Affect You:

• Allergic Reactions: Some people may experience allergic reactions to Blue 1, such as hives, rashes, or asthma-like symptoms, especially if sensitive to food dyes.
• Hyperactivity in Children: Like other artificial dyes, Blue 1 has been linked to hyperactivity and behavioral issues in children, particularly those with ADHD.
• Potential Health Concerns: Though approved by the FDA, there are concerns that Blue 1 may contribute to other health issues, such as digestive problems or even long-term effects from repeated exposure.

How to Avoid It:

To avoid Blue 1, look for it on labels as "Blue 1," "FD&C Blue No. 1," or "E133." It's commonly found in brightly colored candies, ice creams, sodas, and frostings. Opt for products with natural colorings like spirulina or blueberry juice, and choose items that are labeled as free from artificial dyes.
