How many kcal/gram do carbohydrates and proteins provide in enteral nutrition?

  1. 3.4 kcal/gram

  2. 4 kcal/gram

  3. 9 kcal/gram

  4. 2 kcal/mL

The correct answer is: 4 kcal/gram

Carbohydrates and proteins provide 4 kcal/gram in enteral nutrition. This is because carbohydrates and proteins are both macronutrients that provide energy to the body. Carbohydrates are primarily used by the body for energy, while proteins are primarily used to build and repair tissues. Option A, 3.4 kcal/gram, is incorrect as it is the amount of energy provided by pure carbohydrates. Option C, 9 kcal/gram, is also incorrect as it is the amount of energy provided by pure fats. Option D, 2 kcal/mL, is incorrect as it is referring to energy density, not energy provided per gram.
