Why does Lark only comment on a few items I log and not all of them?

The purpose for our new food feature is to provide personalized, multidimensional feedback on meals a user logs. Our primary purpose is to provide information for a user to effectively track progress and patterns and hopefully improve their eating habits. 

Lark selects one or a few logged items, per meal or snack, to comment on, rather than commenting on every item that was logged. This approach allows Lark’s feedback to be focused and clear. It also also helps prevent the coaching from being overwhelming, and allows users to focus on a realistic behavior change to try to make next time. Note that although Lark may not mention each food item in the conversation, it is recording everything that you logged, and those count towards daily and weekly totals.
