I’m am looking for software that I can enter a recipe.

I’m am looking for software that will allow me to enter in a recipe with weights, ingredients and serving size then calculate the nutritional breakdown (protein, fat, carbs, salt, and sugar along with calories. Is there such software?

There are several nutrition websites that provide nutrient analysis of recipes. I would recommend Food Processor by ESHA Research, software used by dietitians, to analyze recipes though it is rather expensive at around $600. For other websites, ask who designed the software to ensure they used research-based algorithms.
