简要总结
Lactose, one of the key nutrients in human milk may be critically important to infants for more reasons than being a source of energy. We are interested in understanding how lactose when compared to other sugars influences how nutrients, specifically macronutrients are handled after digestion and absorption. To date, there have been no studies looking at how fat and protein varies when lactose compared to other sugars is ingested. There may be metabolic advantages to considering lactose for nutrition support of premature infants rather than glucose or dextrose as is often used in intravenous feeds, or the corn syrup solids in lactose-free formulas. We hope the information from this study will provide new information on the unique aspects of lactose.
Hypothesis: The hypothesis is that providing carbohydrate as lactose:
- minimizes the amount of carbohydrate that is converted into fat
- enables a relatively constant metabolic state throughout feeding interval that avoids swings of high to low insulin, glucose, and fats.
