Is this taking "triggers" a bit too far?

I recently read a short piece about Pru Leith, the chef judge on “The Great British Baking Show” being criticized by some for using the phrase “It’s worth the calories” in some of her critiques because it triggers viewers with eating disorders.

I consider myself a fairly sensitive person to the needs of others and do understand the use of trigger warnings – to an extent. But this to me seems the height of ridiculous. Surely, people with eating disorders are aware that food has calories and if they are so sensitive to that notion, shouldn’t watch a show that is all about baked goods.

What’s your opinion on this?
