Um, ok, so wanting to make sure you and your family (skin and fur) eat a healthy diet is now a nervous disorder?
This is a proposed eating disorder which is marked by an excessive preoccupation with eating healthy food. The term was proposed in 1997 by the American physician Steven Bratman who was concerned that an obsession with healthy food could, paradoxically, lead to unhealthy consequences.
Sure it could lead to unhealthy consequences,
if it's unbalanced. Most people who go to the trouble to learn about species-appropriate nutrition (and human nutrition) in the first place,
also learn how to balance the diet. But there are also "unhealthy consequences" to eating lousy food, too. And we're seeing it. So are the doctors and veterinarians.
