Guides
Plain-English explanations of the things the calculator shows you: what each number in a breakdown is telling you, and which changes to a recipe actually move those numbers rather than only the marketing. Every figure quoted comes from the same USDA data the calculator uses, and there is a note on how accurate any of this is.
Every guide
Ingredient swaps that actually work
Which recipe substitutions genuinely change the nutrition, which ones only change the marketing, and how to swap flour, sugar, fat and protein without wrecking the recipe.
Reading a nutrition breakdown
What each number in a nutrition breakdown actually means, which ones are worth acting on, and the two splits that get misunderstood most often — fats and sugars.
Fats and sugars, without the folklore
Which fat and which sugar actually matter, why swapping one sweetener for another changes almost nothing, and what the numbers on a nutrition breakdown are really telling you about both.
