In a balanced diet, what percentage of daily caloric intake should ideally come from fat?

1. 10-15%

2. 20-35%

3. 40-50%

4. 55-60%

The correct answer is: 20-35%

The ideal percentage of daily caloric intake that should come from fat is 20-35%. This range is widely supported by various dietary guidelines and nutrition organizations, recognizing that fats play essential roles in the body, including providing energy, supporting cell growth, aiding in the absorption of certain vitamins (A, D, E, and K), and contributing to hormone production. Fats are a necessary macronutrient, but balancing their intake is vital for overall health. Consuming within the 20-35% range allows for adequate energy levels and promotes cardiovascular health while helping to manage body weight effectively. This percentage encourages the incorporation of healthier fat sources, such as unsaturated fats found in fish, nuts, avocados, and olive oil, while limiting saturated and trans fat intake. Opting for a higher percentage of fat, such as 40-50% or more, can lead to an imbalance in nutrient intake and may increase the risk of health issues if it includes excessive saturated fat or trans fats. Similarly, a lower percentage like 10-15% may not supply enough essential fatty acids needed for optimal health. Therefore, the 20-35% range effectively balances nutrient intake while supporting overall health goals.
