At the moment, you can only add one portion/piece/etc. per food. I would like to add the foods per 100g. Then I want to make a choice that would indicate a portion of a food. For example, with banana: large (165g), medium (130g), small (100g). At the moment, you can only add one portion and if your portion is 150g, for example, you must first multiply the nutritional values of 100g by 1.5 to get to your correct values. Please make it more user-friendly.
