Over time, people with orthorexia will continue to drop food options from their diets. They will have various explanations for doing so, such as sudden allergies to an entire food group, a refusal to consume pesticides, recent conversion to vegetarianism, or supposed negative relationships between certain foods and their mood. The number of acceptable foods will decrease drastically; some people with orthorexia consume fewer than ten foods because they don’t believe anything else is healthy enough.
