How many kcal/gram do fats provide in enteral nutrition?

  1. 3.4 kcal/gram

  2. 4 kcal/gram

  3. 9 kcal/gram

  4. 1.1 kcal/mL

The correct answer is: 9 kcal/gram

Fats provide 9 kcal/gram in enteral nutrition. This is because fats are the most concentrated source of energy, containing more than twice the calories per gram as carbohydrates and proteins. Option A (3.4 kcal/gram) is the calorie content of carbohydrates, option B (4 kcal/gram) is the calorie content of proteins, and option D (1.1 kcal/mL) is the calorie content of enteral formulas. It is important to note that the calorie content of fats can vary depending on the type of fat, but on average they provide 9 kcal/gram in enteral nutrition.
