Can an allergist determine food allergies?

Is food allergy testing accurate?
“Allergists don’t have a test that’s highly accurate for diagnosing food allergy. When you look at the tests that are out there, they’re in about the 80 percent accuracy range,” says Dr. Hugh Sampson, an allergist and professor of pediatrics in the Icahn School of Medicine at Mount Sinai in New York.
Why do food allergies develop later in life?
Some adult-onset food allergies arise from preexisting allergies to pollen, one of the most common environmental allergens. With the body already on high alert for pollen and anything resembling it, an overzealous immune system can become even more hypervigilant and mistake proteins in fruits and vegetables for pollen.
How do you find out if you have a food intolerance?

What is the most accurate food allergy test?

What happens if you keep eating food you’re intolerant to?
What happens if you eat something you’re “intolerant” to? You might get some of the same symptoms as a food allergy, but it can’t trigger anaphylaxis.
