Which component is commonly used as a modular fat source in enteral nutrition formulas?

• A. MCT oil
• B. Safflower oil
• C. Glucose
• D. Protein

Answer: (A)

In enteral nutrition, fats are often added as a modular source to tailor energy and fat tolerance. The most common modular fat source is medium-chain triglyceride (MCT) oil. MCTs are absorbed directly into the portal circulation and don’t require bile salts for emulsification or extensive pancreatic lipase activity, making them easier to absorb and rapidly available for energy. This property is especially useful when fat digestion is impaired or when rapid fat delivery is needed, such as in fat malabsorption or certain liver conditions. Glucose and protein provide non-fat nutrients, so they aren’t used as fat sources, and safflower oil is a fat source but consists of long-chain triglycerides and isn’t manipulated as a modular fat to the same extent as MCT oil.
