Food dyes are substances added to foods to change or intensify their color. Simply put, they are used to make foods more visually appealing. They can be of natural origin, extracted from plants or animals, or artificial, produced in laboratories through chemical processes.

While natural dyes are extracted from plant or animal sources and are closer to nature, artificial dyes, created in the laboratory, allow for more intense and long-lasting colors, ensuring that the finished product always looks uniform. But what are the risks of consuming many artificial dyes?


Where can food coloring be found?

Artificial food dyes are widely used in many industrial products. Some of the most common foods and beverages that contain dyes include:

  • Sweets: candies, chocolates, ice cream and sweet snacks.
  • Soft drinks: many soft drinks and energy drinks contain dyes.
  • Baked goods: cookies, packaged cakes and snacks often use dyes to enhance the appearance of the product.
  • Processed foods: breakfast cereals, ready-to-eat soups, and bagged potato chips.
  • Children's foods: flavored yogurts, fruit juices and candies.
  • Condiments and sauces: ketchup, mustard, colored mayonnaise and other pre-packaged sauces.

How to find out if a product contains artificial coloring?

To understand whether a food contains artificial coloring, the first step is to read the label carefully. Artificial dyes are indicated by the letter "E" followed by a number. Below is a list of the most common artificial colors:

  • Amaranth (E123): Deep red, used in beverages, ice cream and baked goods
  • Indigotine (E132): Intense blue, used in beverages, ice cream and desserts
  • Caramel (E150): Brown, used in beverages, candies and baked goods
  • Brilliant black (E151): Black, used in cake frostings and candies
  • Cochineal red (E124): Deep red, used in sevande, ice cream and baked goods
  • Sunset yellow (E110): Orange yellow, used in sauces, cheeses, desserts
  • Allura red (E129): Bright red used in candies, ice cream and beverages
  • Bright blue (E133): Brilliant blue, used in beverages, ice cream and desserts

What are the risks associated with food dyes?

Although they are considered safe by the relevant authorities, several scientific studies have highlighted possible risks associated with prolonged use and excessive intake of artificial colorings. Potential health consequences associated with these additives include:

  • Allergic reactions: Not everyone tolerates artificial dyes well. They can cause allergic reactions such as skin rashes, hives or respiratory problems. An example is the red dye E120 (cochineal), derived from insects, which can cause allergies in some people.
  • Behavioral problems in children: There is increasing scientific interest in the impact of artificial dyes on children's behavior. Some studies have shown a possible link between the consumption of certain dyes, such as tartrazine (E102), and increased symptoms related to hyperactivity and attention disorders in particularly sensitive children.
  • Long-term toxic effects: Some past studies have suggested a possible link between certain artificial dyes and the development of tumors in animals. However, research on the effects of these dyes on humans has not yet provided conclusive results. The bright blue dye (E133) has received special attention from scientists because of potential health risks and, as a result, has undergone numerous evaluations.

How to avoid food coloring?

Avoiding artificial food coloring may seem complicated, but the health benefits, especially for young children, make this effort definitely rewarding. Here are some habits to adopt:

  • Read labels well: Check for acronyms such as "E" followed by a number (e.g., E102, E110, E133), which identify food dyes approved by the European Union. Prefer foods that do not contain these acronyms or that use natural dyes.
  • Prefer fresh, unprocessed foods: To reduce artificial dyes, choose natural foods such as fruits, vegetables, whole grains and fresh meat. These foods contain no additives and are healthier for the body.
  • Choose natural alternatives: There is a growing trend in the food industry to replace artificial colorings with natural alternatives. Turmeric, chlorophyll and beet extract are just a few examples of natural ingredients used to color foods in healthier and more sustainable ways.
  • Prepare food at home: Cooking at home with fresh ingredients allows us to have full control over what we eat. In this way, we can avoid adding dyes and other additives that could be harmful to our health.

Conclusions:

Food dyes, used to make foods more attractive, are subject to strict health controls. However, scientific studies have shown possible correlations between excessive consumption and some health issues, such as hyperactivity in children. To reduce exposure to these additives, it is advisable to prefer fresh, seasonal and organic foods, and to read labels carefully, trying to identify artificial colorings by the initials 'E' followed by a number.
