Most concerns about food additives have to do with man-made ingredients that are added to foods. Some of these are:
The United States Food and Drug Administration (FDA) has a list of food additives that are thought to be safe. Many have not been tested, but most scientists consider them safe. These substances are put on the "generally recognized as safe (GRAS)" list. This list contains about 700 items.
Congress defines safe as "reasonable certainty that no harm will result from use" of an additive. Examples of items on this list are: guar gum, sugar, salt, and vinegar. The list is reviewed regularly.
Some substances that are found to be harmful to people or animals may still be allowed, but only at the level of 1/100th of the amount that is considered harmful. For their own protection, people with any allergies or food intolerances should always check the ingredient list on the label. Reactions to any additive can be mild or severe. For example, some people with asthma have worsening of their asthma after eating foods or drinks that contain sulfites.
It is important to keep gathering information about the safety of food additives. Report any reactions you have to food or food additives to the FDA Center for Food Safety and Applied Nutrition (CFSAN). Information about reporting a reaction is available at www.fda.gov/about-fda/center-food-safety-and-applied-nutrition-cfsan/contact-cfsan.
Sulfites used in many foods as preservatives cause asthma in some people.
