Food allergies: Rare but risky

 

Food intolerance may produce symptoms similar to food allergies, such as abdominal cramping. But while people with true food allergies must avoid offending foods altogether, people with food intolerance can often eat some of the offending food without suffering symptoms. The amount that may be eaten before symptoms appear is usually very small and varies with each individual.

WHEN FOOD ADDITIVES ARE A PROBLEM

Over the years, people have reported to FDA adverse reactions to certain food additives, including aspartame (a sweetener), monosodium glutamate (a flavor enhancer), sulfur-based preservatives, and tartrazine, also known as FD&C Yellow No. 5 (a food color). The federal Food, Drug, and Cosmetic Act requires that FDA ensure the safety of all substances added to foods, but individual health conditions sometimes cause problems with certain additives.

  • Aspartame

    After reviewing scientific studies, FDA determined in 1981 that aspartame was safe for use in foods. In 1987, the General Accounting Office investigated the process surrounding FDA's approval of aspartame and confirmed the agency had acted properly. However, FDA has continued to review complaints alleging adverse reactions to products containing aspartame. To date, FDA has not determined any consistent pattern of symptoms that can be attributed to the use of aspartame, nor is the agency aware of any recent studies that clearly show safety problems.

    Carefully controlled clinical studies show that aspartame is not an allergen. However, certain people with the genetic disease phenylketonuria (PKU), those with advanced liver disease, and pregnant women with hyperphenylalanine (high levels of phenylalanine in blood) have a problem with aspartame because they do not effectively metabolize the amino acid phenylalanine, one of aspartame's components. High levels of this amino acid in body fluids can cause brain damage. Therefore, FDA has ruled that all products containing aspartame must include a warning to phenylketonurics that the sweetener contains phenylalanine.
