There have been so many comments on 'Recent' or 'Frequent' foods, since it often does not reflect what we would expect or wish. When your food requirements change (due to medical issues, new information or adapting to a new diet) you don't want "old" food items to clutter up your list.
I think it would help to have an option to create 'Favorite Foods', i.e. items you (want to) frequently use. This way you can customize your list for quick and easy picking
Furthermore: I love MyFitnessPal, it has become a crucial tool in monitoring and managing my health! Thank you!
