Limitations

USDA FoodData Central provides free government nutrition data

USDA's FoodData Central offers free nutrition data for generic foods — developers with simple needs may find government data sufficient without a Nutritionix subscription.

Restaurant menu data accuracy depends on operator submissions

Nutritionix restaurant data is submitted by operators — accuracy for regional and independent restaurants varies more than for national chains.
