Search And Calculate Carbohydrate Counts & Get Other Nutrient Information For Thousands Of Foods
Carbohydrates: In the search results, "Carbohydrates (by difference)" is the carb content of foods by residual weight after subtracting any and all amounts of fat, protein, water and ash found in the nutrient chemical analysis. What's left over -- such as sugars, starches, fiber and trace amounts of other organic compounds -- is considered to be carbohydrate. This analysis isn't always absolutely accurate, but is the official method used.
Calories/kcal: In the U.S., energy in foods is expressed in kilocalories (kcal). The scientific
definition of a kilocalorie is the amount of energy needed to raise the temperature of 1
kilogram of water one degree Celsius from 15? to 16? at one atmosphere. The true
calorie, sometimes referred to as a "small calorie," is the amount of energy
needed to raise the temperature of one gram of water one degree Celsius from 15? to 16?
at one atmosphere. A kilocalorie is equal to 1000 calories. While the term
"calorie" technically applies to the "small calorie," in common usage,
such as in reference to food energy, the term "calorie" is actually a
kilocalorie. Internationally, most countries express food energy in kilojoules (kJ). One
kcal equals 4.184 kJ. The USDA Nutrient Database for Standard Reference contains values
for both kilocalories and kilojoules.
