Draft Conclusion Statement

The draft conclusion statements listed below describe the state of the science related to the specific question examined. Draft conclusions are not considered final until they have been deliberated with and decided upon by the full Committee and published in the Committee’s final advisory report. Individual conclusion statements should not be interpreted as dietary guidance or the Committee’s overarching advice to the Departments. 

Human Milk - Quantity

No evidence is available to determine the relationship between maternal dietary patterns during lactation and human milk quantity. Grade: Grade Not Assignable

Insufficient evidence is available to determine the relationship between maternal diets differing in macronutrient distributions during lactation and human milk quantity. Grade: Grade Not Assignable

Human Milk - Fat Composition

Insufficient evidence is available to determine the relationship between dietary patterns consumed during lactation and total fat in human milk. Grade: Grade Not Assignable

Limited evidence suggests that maternal consumption of diets higher in fat (>35% fat) and lower in carbohydrate during lactation is related to higher total fat in human milk collected in maternal postprandial period. Grade: Limited

Limited evidence suggests that certain maternal dietary patterns during lactation, including diets based on macronutrient distributions, are related to the relative proportions of saturated fat and MUFAs in human milk, and PUFAs in human milk collected in maternal postprandial period. Grade: Limited

Human Milk - Protein Composition

No evidence is available to determine the relationship between maternal dietary patterns during lactation and total protein concentration in human milk. Grade: Grade Not Assignable

Insufficient evidence is available to determine the relationship between maternal diets differing in macronutrient distribution during lactation and total protein concentration in human milk. Grade: Grade Not Assignable

No evidence is available to determine the relationship between maternal dietary patterns during lactation and bioactive proteins including alpha-lactalbumin, lactoferrin, casein, alpha (1) antitrypsin, osteopontin, sIgA, lysozyme in human milk. Grade: Grade Not Assignable

Human Milk – Oligosaccharides

No evidence is available to determine the relationship between maternal dietary patterns during lactation and human milk oligosaccharides. Grade: Grade Not Assignable

Human Milk – Vitamins, Choline, Iodine and Selenium

Insufficient evidence is available to determine the relationship between maternal dietary patterns during lactation and vitamin B12 concentration in human milk. Grade: Grade Not Assignable

No evidence is available to determine the relationship between maternal dietary patterns during lactation and vitamin C, choline and B vitamins (other than vitamin B12) in human milk. Grade: Grade Not Assignable

No evidence is available to determine the relationship between maternal dietary patterns during lactation and vitamins A, D, E and K in human milk. Grade: Grade Not Assignable

No evidence is available to determine the relationship between maternal dietary patterns during lactation and iodine and selenium in human milk. Grade: Grade Not Assignable
