Have you ever wondered what carageenan, lecithin and xanthan gum are? These words are often in the ingredient list of pre-packaged foods and are called food additives. Many people try to limit eating foods with food additives. If you have questions about food additives and their role in the food supply, read on to get answers to commonly asked questions.
A food additive is any substance that is added to food in order to preserve it, maintain its quality or make it more appealing.

Health Canada checks food additives to make sure they are safe. Only additives that are approved can be used. These additives are thought to be safe in amounts that are usually eaten. Any new food additive is tested for safety before it is added to the approved list.
Some research says that certain preservatives like benzoic acid and food colourings like tartrazine may increase hyperactivity in children with Attention Deficit Hyperactivity Disorder (ADHD). If your child has ADHD, keep a food diary. You can track what your child eats as well as his or her behaviour to see if food additives are causing symptoms. Preservatives like benzoic acid and food colourings should be avoided if they cause hyperactivity in a child with ADHD. However, not all children with ADHD react to food additives.

Preservatives are a type of food additive that are often used in pre-packaged foods. They prevent or delay food from spoiling due to bacteria, mould, enzymes or other substances. Common food additives include benzoic acid, calcium sorbate, propionic acid and sodium nitrite.

When reading food packaging, look for the following claims. These claims are allowed as long as they are true and accurate. Keep in mind that other naturally occuring additives like salt or vinegar may still be present.
Food additives are widely used in our food supply especially in pre-packaged foods like ready-to-eat meals, canned foods, frozen entrees, bread, processed meat and snack foods. They are used to preserve food, retain its nutrients and make food more appealing.
If you are trying to limit food additives, buy fresh, unpackaged foods, look for foods with a few simple ingredients, try organic foods and look for claims like “no preservatives.” Most importantly, cook and bake at home as often as you can!
