Food intolerance is distinguished from food allergy in what way:
  1. Food intolerance is diagnosed by challenge tests.
  2. One of the causes of food intolerance is the passage of intact proteins across the gastrointestinal tract.
  3. There is no immunologic reaction with food intolerance.
  4. The body uses cellular immunity to combat food intolerance.
Explanation
Answer: C - Food intolerance is distinguished from food allergy by the lack of immunologic reaction, which involves release of an antibody in response to an antigen (allergen). Food allergy, not food intolerance, involves the reaction of the body’s cellular immune system, and is often caused by the passage of intact proteins across the GI tract.
