They can: Food allergies can start at any age (but usually children) and may occur suddenly even after tolerating that particular food many times. They can also seem to occur on the first known exposure, suggesting allergic sensitization through the skin, breast milk or accidental unrecognized source.

Do food allergies start suddenly like when you are eating?

Maybe: The more significant the allergy, the quicker the response. Food allergies often manifest with itching or swelling in the mouth while eating; once swallowed, there may be abdominal cramping. Bloating, nausea, vomiting, or diarrhea. Acute, severe reactions can cause hives, wheezing and loss of blood pressure, but milder, chronic allergy & ingestion can cause rashes such as eczema.

How do I get tested for food allergies? I mean, where do you start?

See an allergist: After the allergist takes a detailed history(ie. What foods you are concerned about and what reactions you experienced) they will decide if skin testing or blood testing is the best way way to start.
