Which fat type is more prevalent in preterm formulas compared with standard infant formulas, and why?

• A. MCT fat calories are a minority in preterm formulas
• B. 40-50% of fat calories in preterm formulas are MCTs because they are easier to absorb
• C. Standard formulas contain MCTs only
• D. No fat is included in preterm formulas

Answer: (B)

In preterm infants, fat digestion and absorption are immature, with limited pancreatic lipase activity and bile salt availability. To support energy needs and minimize malabsorption, formulas for preterm babies include more medium-chain triglycerides. MCTs are absorbed directly into the portal circulation and do not require bile salts or much pancreatic lipase, making them easier to absorb despite prematurity. This is why about 40-50% of the fat calories in preterm formulas come from MCTs, providing readily available energy while allowing fats that require more digestion to contribute as well. Standard infant formulas do not rely as heavily on MCTs; they use more long-chain fats. The idea that there is no fat or that standard formulas contain MCTs only isn’t accurate.
