According to reports, about 4-5% of adults have food allergies, most often caused by allergy to “shellfish, tree nuts, fruits, tomatoes, fish, peanuts and some food additives”. Allergies to food can cause the body to trigger its defenses, releasing antibodies into the bloodstream to combat the intruders.

Symptoms like metallic taste are quite common in cases of allergies, and can appear anywhere from immediately after eating the allergen to hours after eating it. Anaphylaxis, a more severe reaction to food, happens when the body systematically tries to ward off the allergens, and closes off the airways and throat, often causing blood pressure to dramatically decrease and the heart rate to increase. This kind of allergic reaction is usually sudden and needs to be taken care of by professionals immediately. Sometimes, these serious reactions start with a metallic taste in the mouth, which can serve as a warning sign to get help right away.

Allergies & Metallic Taste

Allergies can be a scary thing to deal with, so many people choose to stay away from anything that causes them to have these types of reactions, whether it be hives or a swollen tongue. Carrying an injectable solution(EpiPen), as prescribed by doctors, is another way to ensure your safety if you ever come across the allergen accidentally.
