Final answer:
For someone with a peanut allergy, it is critical to avoid peanut butter, peanut oil, and peanut candies, as all can potentially contain allergenic proteins which may trigger severe allergic reactions, including anaphylaxis.
Step-by-step explanation:
If you are allergic to peanuts, you should avoid all of the above: peanut butter, peanut oil, and peanut candies.
Individuals with peanut allergies should be cautious about what they consume, as peanuts are a common allergen that can cause serious reactions. Peanut butter is a concentrated source of peanuts and poses a significant risk. Peanut oil, although sometimes refined in a way that removes allergenic proteins, can still be dangerous for those with severe allergies. Peanut candies often contain peanuts or traces of peanuts, making them unsafe. The immune system's response to peanut proteins can range from mild symptoms like itching and hives, to life-threatening conditions such as anaphylaxis, where immediate emergency medical treatment is necessary. An anaphylactic reaction can include difficulty breathing, a drop in blood pressure, and loss of consciousness. Due to the severity of peanut allergic reactions, avoidance is the best preventive measure. It's also important to read food labels carefully, as peanut ingredients can appear in unexpected products. Cross-contamination is another concern, so it's essential to be vigilant regarding foods processed in facilities that handle peanuts.
