Factorial estimation

How is Choline intake likely affected during lactation?

Increased intake

What is the bioavailability factor used in the calculation of extra folate intake by lactating women?

2.0

Based on the information provided, what is the Adequate Intake (AI) for linoleic acid (an n-6 fatty acid) during lactation?

13 g/day for all age groups

According to the information provided, which of the following statements about n-3 fatty acid status during lactation is correct?

Lactating women have lower plasma and RBC lipid DHA levels, which may reflect normal physiological responses to changes in endocrine status, lipoprotein and lipid metabolism, and nutrient transfer

Based on the information provided, which of the following statements about the demand for n-3 polyunsaturated fatty acids (PUFAs) in human milk is correct?

The demand is met through a combination of n-3 PUFAs from maternal tissues and dietary intake

According to the information provided, which of the following statements about carbohydrate requirements during lactation is correct?

Carbohydrate requirements increase during lactation due to the preferential use of glucose by the mammary gland and the need for lactose synthesis

Learn about the increase in protein and amino acid requirements during lactation, as well as the role of non-protein nitrogen (NPN) in human milk production. Understand the conversion of NPN to protein and the factorial estimate of the increase in protein requirement associated with lactation.
