What Is Food Coloring?

The FDA defines food coloring as a pigment, dye, or other substance used to give color to food, body parts, drugs, or cosmetics.

There are only two types of food coloring that the FDA approves. They are dyes that quickly dissolve when added to water and additives contained in oils and fats that are not soluble in water.

Food colorings are synthetic or come from colorants in animals, minerals, or vegetables. The FDA closely regulates the coloring to ensure that any products containing them are labeled and safe. While they are safe, you still need to be careful when giving them to your animals.

While there are many natural colors, artificial food coloring is more common. This is because they are cheaper to use, can be made in large batches, and have a longer shelf life.

However, only ten artificial food colorings are FDA-approved and said to be safe for animals and humans. These are blue number one, blue number two, red number 40, green number three, and also yellow number five, to name a few. Some of these, however, have been banned in other countries.

Is Using Food Coloring Safe?

Food dyes are used to enhance food and make it more appealing. After all, who wants to eat a hot dog that has no color? Some studies show a correlation between food coloring, certain allergies, and even hyperactivity in children, but should you give it to your cat? Most cat food allergies as we understand at present are caused by protein, not food dyes. If you’re still unsure if it’s a good idea to give your cat food with artificial coloring, make an appointment with your vet.
