Suggestion - Unliking – Fooducate: Nutrition Coach Review

This app works quite well for tracking one's nutritional intake. I really appreciate the ability to view better alternatives to certain foods. However, one slight annoyance I have is with the liking system. If you accidentally like an item, you can't "unlike" it, you can only dislike it, which does take it off your "list" but it brings the average of the product down. This is important for situations in which one hasn't tried the product but has given accidental feedback through tapping a heart. I would appreciate if an implement could be made in which a user can simply tap the heart again, and the like would go away. Otherwise, I have no qualms with this app and use it daily.
