Identifying Ingredient Substitutions Using a Knowledge Graph of Food.

People can affect change in their eating patterns by substituting ingredients in recipes. Such substitutions may be motivated by specific goals, like modifying the intake of a specific nutrient or avoiding a particular category of ingredients. Determining how to modify a recipe can be difficult because people need to 1) identify which ingredients can act as valid replacements for the original and 2) figure out whether the substitution is "good" for their particular context, which may consider factors such as allergies, nutritional contents of individual ingredients, and other dietary restrictions.
