Item ratings gradually reflect your own entries alongside general food information. Log what matters to you Record a meal, an activity, or a stressful situation, then add how you felt. Include portion size and freshness when logging food. Fill in only what you want to track. Save recurring meals and other entries as templates to use again. Ratings based on your entries Over time, Histeva displays an item value based on how you rated your previous entries. You can review your personal history alongside general information.

The colors are not a list of allowed and forbidden foods. Histeva also takes your own entries into account when displaying items.
