Nutrition Diet: What foods have FD&C Blue No. 1?

According to the Center for Science in the Public Interest, FD&C Blue No. 1 is found in thousands of food products, including beverages, candy, and baked goods. Understanding what foods have FD&C Blue No. 1 is the first step toward making more informed dietary choices and reducing your intake of artificial food colors.

Quick Summary

This guide outlines the various common and surprising foods that contain the artificial food dye FD&C Blue No. 1. It details the potential health concerns associated with artificial colorings and provides practical advice on how to identify and eliminate them from your diet for better overall nutrition.

Key Points

• Prevalence: FD&C Blue No. 1, or Brilliant Blue FCF, is a synthetic food dye found in thousands of processed foods and drinks, including candies, sports drinks, and cereals.

• Aesthetic Purpose: The dye serves no nutritional value and is used exclusively for coloring products, often to make them more visually appealing.

• Potential Health Risks: Concerns include links to hyperactivity and neurobehavioral issues, particularly in sensitive children, and potential allergic reactions.

• Read Labels: The easiest way to avoid the dye is to carefully read ingredient lists and look for "FD&C Blue No. 1," "Blue 1," or "Brilliant Blue FCF".

• Prioritize Whole Foods: Shifting a diet to focus on whole, unprocessed foods naturally free of artificial colorings is the most effective strategy.

• Natural Alternatives: Natural sources like spirulina, beets, and turmeric can be used as alternatives to create color in food when cooking from scratch.

FD&C Blue No. 1, also known as Brilliant Blue FCF or E133 in Europe, is a synthetic food colorant widely used in the food industry to give products a bright, vibrant blue hue. Derived from petroleum, this dye serves no nutritional purpose and is added purely for aesthetic appeal. While deemed safe for general consumption by the FDA, concerns about its potential health effects, particularly in children, have led many health-conscious consumers to scrutinize ingredient labels more carefully.

Common Foods Containing FD&C Blue No. 1

This artificial dye is used in a wide array of processed foods and drinks, often in combination with other colors to create green, purple, or other shades. The most common categories include:

• Confectionery: Candy, chewing gum, fruit-flavored snacks, and icings often feature FD&C Blue No. 1 to create bright, eye-catching colors. Popular examples include blue raspberry flavored candies, some marshmallows, and cake decorating gels.
• Beverages: Many drinks marketed to children, sports drinks, and certain alcoholic beverages contain the dye. This includes fruit punches, sodas, and even flavored water products. The liqueur Blue Curaçao is a classic example of a product colored with Brilliant Blue FCF.
• Dairy Products: Certain dairy items are artificially colored to appear more appealing. Flavored yogurts, ice cream, and some dairy powders may list the dye on their ingredient labels.
• Desserts and Baked Goods: Beyond just icing, the dye is found in various desserts, including gelatin mixes (like Jell-O), pudding cups, popsicles, and packaged baked goods. Cereals with colorful pieces, such as Froot Loops, are also a source.
• Other Processed Foods: The dye can be found in more surprising places, including some brands of canned processed peas, packet soups, and salad dressings. Even some varieties of smoked salmon have been found to contain it.

Potential Health Concerns and Controversies

While FDA-approved, FD&C Blue No. 1, along with other synthetic dyes, has faced scrutiny from health advocacy groups like the Center for Science in the Public Interest (CSPI) and various research bodies. The main concerns include:

• Hyperactivity in Children: Several studies, including the Southampton study in the UK, have explored the link between artificial food colors and increased hyperactivity and behavioral problems in children. While results can be mixed, some evidence suggests a link for sensitive individuals. As a result, the European Union has mandated warning labels on foods containing certain dyes, including Brilliant Blue FCF.
• Allergic and Hypersensitivity Reactions: Some individuals, particularly those with pre-existing conditions like asthma, may experience allergic or hypersensitivity reactions to artificial dyes, including FD&C Blue No. 1.
• Toxicity in Medical Use: In a specific, non-dietary context, reports of toxicity have emerged when FD&C Blue No. 1 was used to tint enteral feeding formulas for critically ill patients. These cases, involving systemic absorption of the dye, resulted in severe metabolic acidosis and other complications, highlighting potential risks outside of normal dietary consumption.

How to Avoid FD&C Blue No. 1 in Your Diet

Eliminating artificial dyes requires vigilance when shopping and cooking. Here are practical steps you can take:

• Read ingredient labels thoroughly. This is the most crucial step. Look for "FD&C Blue No. 1," "Brilliant Blue FCF," "Blue 1," or the European code "E133".
• Focus on whole, unprocessed foods. The easiest way to avoid artificial colorings and other additives is to build your diet around whole foods like fresh fruits, vegetables, whole grains, and lean proteins.
• Cook and bake from scratch. This gives you complete control over the ingredients. For color, use natural alternatives like spirulina for blue or beet extract for red.
• Seek out dye-free alternatives. Many brands now offer products specifically marketed as free from artificial colors. The label will often state "no artificial colors".

Comparison of Artificial and Natural Food Colors

Feature	Artificial Colors (e.g., FD&C Blue No. 1)	Natural Colors (e.g., from spirulina, beets)
Source	Petroleum or coal tar	Plant and mineral-based extracts
Purpose	Purely aesthetic; makes food visually appealing	Aesthetic, but can also offer some nutritional benefits
Stability	Very stable, vibrant, and long-lasting	Less stable, can fade over time, and affected by heat/pH
Health Implications	Linked to hyperactivity, allergic reactions, and under review for other risks	Generally recognized as safe (GRAS), though some may cause rare allergic reactions
Cost	Typically inexpensive to produce	Generally more expensive due to processing requirements
Nutritional Value	None	Some sources, like spirulina, have nutritional benefits
Labeling	Explicitly listed by name (e.g., "FD&C Blue No. 1") or E-number	Listed by source (e.g., "Spirulina Extract," "Beet Juice")

Conclusion

FD&C Blue No. 1, while widespread in a variety of processed foods and drinks, is a synthetic dye that serves no purpose beyond aesthetics. For consumers, especially parents, minimizing or eliminating this and other artificial colorings from the diet can help address potential behavioral issues or allergic sensitivities. Shifting focus toward whole, unprocessed foods is the most effective strategy for managing intake of this and other additives. By reading labels carefully and choosing natural alternatives, it is possible to make more informed choices that support a healthier nutritional diet for the entire family.
