What percentage of daily intake should fats constitute?

• A. 10%
• B. 20%
• C. 30%
• D. 50%

Answer: (C)

How much of daily energy should come from fats? Fats are energy-dense, providing about 9 kcal per gram, so it's important to set a moderate proportion of total energy from them. Most guidelines place fats around a quarter to a third of daily energy, with 30% commonly used as a target. This level helps ensure enough essential fatty acids and fat-soluble vitamins while avoiding excess energy intake and too much saturated fat. Too little fat can miss essential fats and vitamin absorption; too much—about half the daily energy—can raise health risks. So 30% fits well with the recommended range and is a typical exam target.
