Have You Ever Wondered 109

. . . if avoiding certain foods during pregnancy can prevent food allergies in the baby? There's no conclusive evidence that restricting foods during pregnancy makes any difference. In fact, it's not recommended. Babies born to mothers who have restricted their diets during pregnancy often have lower birthweights.

most are caused by allergens in tree nuts, eggs, peanuts, or shellfish (crustacea).

Is the reaction the same every time? Perhaps not. Its severity depends on two things: how allergic a person is and how much allergen is consumed.

Warning! If you—or a family member—experience severe food reactions, plan in advance how to handle accidental ingestion of the "trigger" allergen. The person should wear an identification bracelet or necklace to alert others, and should carry epinephrine (adrenaline) that can be injected quickly to counter the allergen. Your health care professional will give you a prescription. Because the body's responses can be life-threatening, call 911 or an ambulance immediately if someone has severe allergic reactions.
