Approach to Answering the Question
NESR Systematic Review

Subcommittee

Systematic Review Protocol
Developed for each scientific question being examined, the protocol describes the plan for how the systematic review was conducted. The protocol provides the:

  • Analytic framework,
  • Literature search and screening plan, and
  • Literature search and screening results.

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.

Pregnancy

Food allergies

Limited evidence suggests no relationship between soybean consumed during pregnancy only and risk of food allergy in the child. Grade: Limited

Insufficient evidence is available to determine the relationship between lower or restricted consumption of cow milk products during pregnancy only, or during both pregnancy and lactation, and risk of food allergy in the child. Grade: Grade Not Assignable

Insufficient evidence is available to determine the relationship between peanuts, eggs, or wheat consumed during pregnancy only and risk of food allergy in the child. Grade: Grade Not Assignable

No evidence is available to determine the relationship between dietary patterns or fish, tree nuts and seeds, and foods not commonly considered to be allergens such as meat, vegetables, and fruits consumed during pregnancy only and risk of food allergy in the child. Grade: Grade Not Assignable

Atopic dermatitis

Moderate evidence suggests that a lower or restricted consumption of cow milk products during pregnancy only does not reduce the risk of atopic dermatitis/eczema in the child. Grade: Moderate

Moderate evidence suggests that lower or restricted consumption of egg during pregnancy only does not reduce the risk of atopic dermatitis/eczema in the child. Grade: Moderate

Insufficient evidence is available to determine the relationship between cow milk products and eggs restricted during both pregnancy and lactation and risk of atopic dermatitis/eczema in the child. Grade: Grade Not Assignable

Limited evidence suggests that fish consumed during pregnancy only does not increase the risk of atopic dermatitis/eczema in the child. Grade: Limited

Limited evidence suggests that dietary patterns during pregnancy only are not associated with risk of atopic dermatitis/eczema in the child. Grade: Limited

Insufficient evidence is available to determine the relationship between peanuts, soybean, wheat/cereal, yogurt and probiotic milk products, and foods not commonly considered to be allergens, such as meat, vegetables, and fruits, consumed during pregnancy only and risk of atopic dermatitis/eczema in the child. Grade: Grade Not Assignable

No evidence is available to determine the relationship between tree nuts and seeds consumed during pregnancy only and risk of atopic dermatitis/eczema in the child. Grade: Grade Not Assignable

Allergic rhinitis 

Moderate evidence suggests that lower or restricted consumption of eggs during pregnancy only does not reduce the risk of allergic rhinitis in the child. Grade: Moderate

Limited evidence suggests that dietary patterns during pregnancy only are not associated with risk of allergic rhinitis in the child. Grade: Limited

Insufficient evidence is available to determine the relationship between cow milk products (fermented or non-fermented) consumed during pregnancy only, or during both pregnancy and lactation, and risk of allergic rhinitis in the child. Grade: Grade Not Assignable

Insufficient evidence is available to determine the relationship between fish, peanuts, tree nuts, soybean, wheat, and foods not commonly considered to be allergens, such as meat, vegetables, and fruits consumed during pregnancy only and risk of allergic rhinitis in the child. Grade: Grade Not Assignable

No evidence is available to determine the relationship between seeds consumed during pregnancy only and the risk of allergic rhinitis in the child. Grade: Grade Not Assignable

Asthma

Limited evidence suggests no relationship between eggs consumed during pregnancy only and risk of asthma in the child. Grade: Limited

Limited evidence suggests no relationship between fish consumed during pregnancy only and risk of asthma in the child. Grade: Limited

Limited evidence suggests that a lower or restricted consumption of cow milk products during pregnancy only does not reduce risk of asthma in the child. Grade: Limited

Insufficient evidence is available to determine the relationship between cow milk products consumed during both pregnancy and lactation, and risk of asthma in the child. Grade: Grade Not Assignable

Insufficient evidence is available to determine the relationship between maternal dietary patterns or peanuts, tree nuts, soybean, and other foods such as wheat/whole grains, vegetables, fruits, beverages, and margarine consumed during pregnancy only and risk of asthma in the child. Grade: Grade Not Assignable

No evidence is available to determine the relationship between seeds consumed during pregnancy only and risk of asthma in the child. Grade: Grade Not Assignable

Lactation

Food allergy

Insufficient evidence is available to determine the relationship between lower or restricted consumption of cow milk products during both pregnancy and lactation, and risk of food allergy in the child. Grade: Grade Not Assignable

No evidence is available to determine the relationship between maternal dietary patterns or cow milk products, eggs, peanuts, soybean, wheat, fish, tree nuts and seeds, and  foods not commonly considered to be allergens, such as meat, vegetables, and fruits consumed during lactation only and risk of food allergy in the child. Grade: Grade Not Assignable

Atopic dermatitis

Insufficient evidence is available to determine the relationship between cow milk products restricted during both pregnancy and lactation, or during lactation only, and risk of atopic dermatitis/eczema in the child. Grade: Grade Not Assignable

Insufficient evidence is available to determine the relationship between egg consumption restricted during both pregnancy and lactation and risk of atopic dermatitis/eczema in the child. Grade: Grade Not Assignable

No evidence is available to determine the relationship between maternal dietary patterns or yogurt and probiotic milk products, eggs, fish, peanuts, tree nuts and seeds, soybean, wheat/cereal, and foods not commonly considered to be allergens, such as meat, vegetables, and fruits, consumed during lactation only and risk of atopic dermatitis/eczema in the child. Grade: Grade Not Assignable

Allergic rhinitis 

Insufficient evidence is available to determine the relationship between cow milk products consumed during both pregnancy and lactation, and risk of allergic rhinitis in the child. Grade: Grade Not Assignable

No evidence is available to determine the relationship between maternal dietary patterns or cow milk products, eggs, fish, peanuts, tree nuts and seeds, soybean, wheat, and foods not commonly considered to be allergens, such as meat, vegetables, and fruits consumed during lactation only and risk of allergic rhinitis in the child. Grade: Grade Not Assignable

Asthma

Insufficient evidence is available to determine the relationship between cow milk products consumed during both pregnancy and lactation, or during lactation only and risk of asthma in the child. Grade: Grade Not Assignable

Insufficient evidence is available to determine the relationship between fish, and other foods, such as margarine, oil, butter and butter-spreads, industrial fat, meat, and meat products consumed during lactation only and risk of asthma in the child. Grade: Grade Not Assignable

No evidence is available to determine the relationship between maternal dietary patterns or eggs, peanuts, wheat, tree nuts and seeds, and soybean, consumed during lactation and risk of asthma in the child. Grade: Grade Not Assignable
