What is the acceptable macronutrient range for fat in an adult’s diet?

The acceptable macronutrient distribution range (AMDR) for fat in an adult’s diet is between 20% and 35% of total daily caloric intake. This guideline is established to promote health while ensuring that individuals obtain adequate amounts of essential fatty acids and fat-soluble vitamins.

The chosen answer, which specifies 20%, aligns with the lower end of this range. It's important to recognize that while 20% is acceptable, it is important to also consider the higher end (up to 35%) for those who might need a higher fat intake based on specific dietary requirements, such as higher levels of physical activity or particular health goals.

Fats are essential for numerous bodily functions, including providing energy, supporting cell growth, protecting organs, and helping the body absorb nutrients. Therefore, incorporating healthy fats into one's diet, while still adhering to the recommended range, is vital for overall health. The other choices fall outside of the appropriate range for dietary fat intake based on AMDR guidelines, with numbers not supporting a balanced nutritional approach for adults.
