Lead is an ingredient in many artificial food colorings. An artificial food coloring is added to a food or other product in order to make it more appealing, to disguise natural color variations, or to offset color loss due to sun exposure, humidity, etc. Compared to natural colorings, artificial ones are less expensive, so they are a preferred choice of many manufacturers. Artificial food colorings add neither taste nor nutritional value to food and since they are made from coal tar and petrochemicals, our bodies are unable to digest them.
Food colorings have been linked to a number of different health conditions such as anxiety, cancer, brain tumours, allergies, migraines, blurred vision and asthma. Even though the jury is still out on the question if food colorings cause behaviour problems, by now, it has been well-researched and documented that lead plays a causal role in the development of behaviour problems, ADHD, hyperactivity, as well as learning disabilities and reduced IQ. It is true that the amount of lead contained in these artificial colorings meets the guidelines of the US Food and Drug Administration, but it is also true that not all lead gets excreted once consumed. Some of the ingested lead accumulates in the human body. So what is a minute amount at a single dose, becomes a dangerous amount as an over-the-years build up in the brain, teeth, bones and soft tissue.
Artificial food colorings are abundant in most of our foods and personal care products. They are present in drinks, (including juices, sports and re-hydration beverages). They are an added ingredient in candy, cereals, oranges and syrups. They lurk in jams, cake and soup mixes, and condiments. They are found in fruit cocktail, meal replacement bars and powders, instant noodles, bakery products and icing. They are an ingredient in popular snack foods, even the ones marketed as "healthy." Colorings are used in the preparation of cheese, sausage and salmon. They are an ingredient in pet food. Artificial colorings find their way into personal care products such as face and hand cream, lotion, shampoo, conditioner, soap, toothpaste and chapstick. These colorings also hide in medication, including children’s remedies and vitamins.
Artificial colorings, and the lead contained in them, should and can be avoided. It only requires that we start paying attention to what is listed on food labels. If an item contains artificial colors DON'T buy it. Initially, it might present itself as a little challenge, but since we, humans, are creatures of habit, and we tend to buy the same products repeatedly, with time, this task will become just someting you do.
For more information on artificial food coloring visit the US Food and Drug Administration website. It offers a wealth of official government information about the various approved colorings and their content (including lead, mercury, arsenic, etc). In order to access the detailed information on each additive, scroll down the page, and click on the number in the 21 CFR Section.
