The Data in DataYourEat

• We cannot guarantee the accuracy of the data presented. Indeed, there are multiple recognized systems for determining a food's calorie count and the system used differs around the world.
• USDA FoodData Central provides calorie counts that are based on the Atwater specific factor system.
• The pie charts shown on DataYourEat are meant to give an overview of how many calories each macro (alcohol, fat, carbohydrates, protein) contributes. They may prove especially helpful to those following a diet that factors in macro ratios, such as the ketogenic diet.
• The pie charts differentiate three types of carbohydrates: sugar alcohols (polyols), dietary fiber, and all remaining carbohydrates (net carbs). We provide more details here, as sugar alcohols and dietary fiber are only partially digested and have a different effect on the body. For example, sugar alcohol generally do not increase blood sugar as much as other carbohydrates, and dietary fiber can even help reduce blood sugar levels and variance.
• Furthermore, dietary fiber is classified differently in some countries. For example, on nutrition fact labels in the US, dietary fiber is listed as a constituent of carbohydrates. In contrast, in Europe, it is listed by itself. This means calculating a food's net carbs has to be adjusted: in the US system you have to subtract the dietary fiber from the total carbs, whereas in the European system you must not.
• As of December 2018, DataYourEat determines the calorie counts used for the pie charts by applying the conversion factors for the calculation of energy proposed in Regulation (EU) No 1169/2011 of 25 October 2011. The only exceptions are sugar alcohols, for which we apply more precise factors for specific polyols.

  Fats

  • 9 kcal/g for fats excluding salatrims
  • 6 kcal/g for salatrims

  Carbohydrates

  • 4 kcal/g for carbohydrates excluding dietary fiber and sugar alcohols (polyols)
  • 2 kcal/g for dietary fiber
  • 2.4 kcal/g for sugar alcohols generally, but if the specific polyols are known, we use more precise factors, as suggested in Position of the Academy of Nutrition and Dietetics: Use of Nutritive and Nonnutritive Sweeteners, page 746 (published in the Journal of the Academy of Nutrition and Dietetics, May 2012 Volume 112 Number 5):
    • 0.2 kcal/g for erythritol
    • 2.0 kcal/g for isomalt and lactitol
    • 2.1 kcal/g for maltitol
    • 1.6 kcal/g for mannitol
    • 2.6 kcal/g for sorbitol
  • 3 kcal/g for organic acids

  Protein

  • 4 kcal/g for protein

  Alcohol (Ethanol)

  • 7 kcal/g for alcohol
  We may adjust these numbers slightly to better match a food item's provided calorie count. Additionally, we may modify the system without updating this page.

• We acknowledge that some people want to or have to avoid specific foods. DataYourEat therefore allows basic food items to be tagged with a number of allergens. You can restrict searches for recipes to exclude foods with specific allergens.
• We cannot guarantee the accuracy of the data presented. It may be incomplete or incorrect.
• Internationally different regulations apply for which allergens have to be declared on labels. This complicates adding allergen data.
• You can help improve our data by inputting all allergens you are aware of when creating new basic food items. Allergens in a recipe are determined automatically based on the allergens present in its ingredients.
• You can send us feedback if you find a basic food with incorrect or incomplete allergens. We want to streamline this process in the future, so that you can adjust the data yourself and send it for review.
