Final answer:
Additional allergy information on food packaging may not be the best idea due to the allergenic nature of processed foods, the challenge of labeling all allergens, and the need for individuals with severe allergies to be vigilant regardless of packaging labels.
Step-by-step explanation:
Additional allergy information on food packaging may not be the best idea for a few reasons. First, processed foods tend to be more allergenic than whole foods due to the preservatives and additives used. These additives can cause problems for individuals with allergies, such as sulfites, artificial sweeteners, artificial colors and flavors, and sodium nitrate. Second, labeling every possible allergen on food packaging may be overwhelming and impractical, as there are many different allergens and cross-contamination risks. Lastly, individuals with severe allergies should already be cautious and avoid foods that are likely to contain allergens, rather than relying solely on packaging labels.
