General Questions About Food Additives

What is a food additive?

In its broadest sense, a food additive is any substance added to food. Legally, the term refers to "any substance the intended use of which results or may reasonably be expected to result-directly or indirectly-in its becoming a component or otherwise affecting the characteristics of any food."

Food packaging manufacturers must prove to the U.S. Food and Drug Administration (FDA) that all materials coming in contact with food are safe before they are permitted for use in such a manner.

Why are additives used in foods?

Additives perform a variety of useful functions in foods that are often taken for granted. Since most people no longer live on farms, additives help keep food wholesome and appealing while en route to markets sometimes thousands of miles away from where it is grown or manufactured. Additives also improve the nutritional value of certain foods and can make them more appealing by improving their taste, texture, consistency or color.

Some additives could be eliminated if we were willing to grow our own food, harvest and grind it, spend many hours cooking and canning, or accept increased risks of food spoilage. But most people today have come to rely on the many technological, aesthetic and convenience benefits that additives provide in food.

Additives are used in foods for five main reasons:

• To maintain product consistency.
• To improve or maintain nutritional value.
• To maintain palatability and wholesomeness.
• To provide leavening or control acidity/alkalinity.
• To enhance flavor or impart desired color.

Many substances added to food may seem foreign when listed on the ingredient label, but are actually quite familiar. For example, ascorbic acid is another name for Vitamin C; alphatocopherol is another name for Vitamin E; and beta-carotene is a source of Vitamin A. Although there are no easy synonyms for all additives, it is helpful to remember that all food is made up of chemicals. Carbon, hydrogen and other chemical elements provide the basic building blocks for everything in life.

How are additives regulated?

Additives are not always byproducts of 20th century technology or modern know-how. Our ancestors used salt to preserve meats and fish; added herbs and spices to improve the flavor of foods; preserved fruit with sugar; and pickled cucumbers in a vinegar solution.

Over the years, however, improvements have been made in increasing the efficiency and ensuring the safety of all additives. Today food and color additives are more strictly regulated than at any other time in history. The basis of modern food law is the Federal Food, Drug, and Cosmetic (FD&C) Act of 1938, which gives the Food and Drug Administration (FDA) authority over food and food ingredients and defines requirements for truthful labeling of ingredients.

The Food Additives Amendment to the FD&C Act, passed in 1958, requires FDA approval for the use of an additive prior to its inclusion in food. It also requires the manufacturer to prove an additive's safety for the ways it will be used.

Specific Questions

What Are Some Specific Additives?

For information about the following specific types of additives, see the FDA's Food, Nutrition, and Cosmetics Questions and Answers.

• "Natural" Additives and "Artificial" or "Manmade" Additives
• Fat Substitutes
• Olestra
• Aspartame
• Monosodium Glutamate (MSG)
• Sulfites

What should I do if I suspect I have a food allergy?

The Food Allergy Network's Anne Munoz-Furlong suggests keeping a food diary as a first step, writing down everything you eat or drink for a one- or two-week period. Note any symptoms and how long it took for such symptoms to develop.

But Furlong and other experts agree that those who suspect food allergies also need to be evaluated by a physician with intensive specialty training in allergy and immunology. Be sure to discuss what diagnostic and treatment plan is anticipated, and the costs.

Why are decisions sometimes changed about the safety of food ingredients?

Since absolute safety of any substance can never be proven, decisions about the safety of food ingredients are made on the best scientific evidence available. Scientific knowledge is constantly evolving. Therefore, federal officials often review earlier decisions to ensure that the safety assessment of a food substance remains up to date. Any change made in previous clearances should be recognized as an assurance that the latest and best scientific knowledge is being applied to enhance the safety of the food supply.

Color Additives

What is a color additive?

Technically, a color additive is any dye, pigment or substance that can impart color when added or applied to a food, drug, cosmetic or to the human body. The Food and Drug Administration is responsible for regulating all color additives used in the United States.

Do color additives in food cause hyperactivity?

Although this theory was popularized in the 1970's, well-controlled studies conducted since then have produced no evidence that food color additives cause hyperactivity or learning disabilities in children. A Consensus Development Panel of the National Institutes of Health concluded in 1982 that there was no scientific evidence to support the claim that colorings or other food additives cause hyperactivity. The panel said that elimination diets should not be used universally to treat childhood hyperactivity, since there is no scientific evidence to predict which children may benefit.

Why are color additives used in foods?

Color is an important property of foods that adds to our enjoyment of eating. Nature teaches us early to expect certain colors in certain foods, and our future acceptance of foods is highly dependent on meeting these expectations.

Color variation in foods throughout the seasons and the effects of food processing and storage often require that manufacturers add color to certain foods to meet consumer expectations.

General Questions About Foodborne Illness and Food Preparation

What can I do to protect myself from food poisoning?

Follow the food safety rules listed below:

• Buy only pasteurized dairy products, as indicated on the label, and hard cheeses marked "aged 60 days" (or longer) if unpasteurized milk is used to make them.
• After you've handled or cut raw meat, poultry or seafood, wash your hands, the cutting board, counter, knives, and any other utensils you've used with hot soapy water before you use them again to prepare any other food.
• Thoroughly cook all meat, poultry and seafood, especially shellfish.
• Cover and store leftover cooked food in the refrigerator as soon as possible.
• Reheat all leftovers until they are steaming hot.
• Thoroughly wash raw fruits and vegetables with tap water.
• Follow label instructions on products that must be refrigerated or that have a "use by" date.
• Keep the inside of the refrigerator and the counter tops clean.

Who can I call to obtain more information about seafood products?

The U.S. Food and Drug Administration's Center for Food Safety and Applied Nutrition has a toll-free Seafood Hotline for consumers. The hotline offers information to consumers in English and Spanish, 24 hours a day, 7 days a week. Over 20 recorded informational messages are offered, as well as almost 75 publications, which may be mailed or automatically faxed to callers. Information is available on safe seafood purchasing, handling, cooking, and storage, as well as on nutrition, labeling, economic fraud, additives, pesticides, contaminants, and general food safety. Public affairs specialists are available from noon to 4 p.m. EST Monday through Friday to answer specific questions. If you call the Seafood Hotline, because you saw it here on the Internet, please mention that when calling.

The FDA Seafood Hotline: 1-800-332-4010 (or 202-205-4314 in the DC Area)

What should I do if I have a problem with a food product?

Problems:

1. My hot dog has a strip of plastic inside.
2. The canned chili contains a metal washer.
3. I think a restaurant dinner made me ill.
4. A sugar-coated roach was in my box of cereal.

For help with meat, poultry, and egg products (examples A and B): Call the toll-free USDA Meat and Poultry Hotline at 1 (800) 535-4555.

For help with restaurant food problems (example C): Call the Health Department in your city, county or state.

For help with non-meat food products (example D): For complaints about food products which do not contain meat or poultry--such as cereal--call or write to the Food and Drug Administration (FDA). Check your local phone book under U.S. Government, Health and Human Services, to find an FDA office in your area.

If you think you are ill, see a physician.

1. If an injury or illness allegedly resulted from use of a meat or poultry product, you will also need to tell the hotline staff about the type, symptoms, time of occurrence and name of attending health professional (if applicable).
2. If you can't reach the hotline staff, or if an injury or illness allegedly resulted from restaurant food, call your local Health Department.
3. If an injury or illness allegedly resulted from non-meat food products, call or write to the FDA.

The bottom line: If you sense there's a problem with any food product, don't consume it. "When in doubt, throw it out."

Do new consumer products enhance or endanger food?

New consumer products make it possible to thaw food without electricity, cook it with sunlight, determine its doneness and warm it at a picnic. But are these products "too good to be true"? Will they contribute to foodborne illness?

Some may; some may not. The USDA Meat and Poultry Hotline checked with microbiologists and other government agencies and reports findings and thawing trays, solar box cooking, disposable temperature indicators, and thermoelectric cooler/warmers.
