Since the ingredients can vary greatly for dishes, you should ideally enter all components. Regarding this, there is no other option than to ask for the nutrition facts or estimate them.
As soon as you know the ingredients of a dish, you can create a meal or a recipe and use it in the future, without the need to always enter the ingredients over again.
We hope that you were able to find answers to all your questions and wish you a great journey with YAZIO. Should you have any more questions, please feel free to contact our support team and submit your request here.
