Always Truthful Jon: A better diet

Jon decided that he might as well test his ability elsewhere, so he walked downstairs into the kitchen. His mom was in the living room, reading a book. Feeling a little hungry, he slipped past her into the kitchen. He had a bag of chips in one hand and a Mountain Dew in the other before her heard her call out, "Jon, don't eat too much junk food. We're having dinner soon." He groaned. But then an idea occurred to him. "I'm not eating junk food Mom." He said, hoping to convince her chips were healthy. "Of course not, dear. Why would we have any in the house?" she asked. "Right," said Jon, wondering why he had said that. He took a couple bites out of his apple and rinsed them down with a drink of water. As he ate his healthy snack, he thought about the first thing he wanted to do with his new ability.
