The correct responses regarding how food allergies impact an individual's life are:
- They may carry epinephrine to prevent anaphylactic shock if they eat an allergen.
- They may get shots to help them become less sensitive to the allergen.
- They must read the ingredient lists on food products carefully.
The statement "They cannot eat foods prepared in restaurants or grocery stores" is not entirely accurate. While individuals with food allergies may need to be cautious and can face significant risks with cross-contamination, many do eat out or purchase prepared foods by thoroughly communicating their allergies and ensuring safe practices are in place.
