How do Maternal Diet and Infant Complementary Feeding Influence Food Allergy?

Maternal Diet


The prevalence of allergy disorders in children appears to have risen dramatically in recent decades. Because environmental variables, including diet, are thought to have a substantial influence in the development of these diseases, there is a lot of interest in identifying early nutritional intervention preventive measures.

Breastfeeding affects the establishment of a healthy gut microbiota and is important for the immunological development of new born and babies due to immune-modulating capabilities.

However, the evidence for breastfeeding’s protective function against the development of food allergies in children is mixed, and there’s little data to back up the benefits of an antigen-free diet during lactation.

Although no definitive conclusion can be drawn concerning the protective effect of breast milk against allergic disorders, exclusive breastfeeding is still recommended for the first six months of life due to the health benefits.

How to do Maternal Diet?

Environmental exposures, such as food intake during key phases of pregnancy and the early postnatal period, play a significant influence in the development of the baby immune system, and it has been hypothesized that they may also play a role in the onset of childhood atopic illnesses.

This maternal diet will give your child a better mind because of the diet foods, where you will be able to take only fruits, fish, vegetables, whole grains and many more. That’s why it is important and you have to follow this maternal diet strictly, because only this thing will provide complete security to your child.

Many researchers have looked at the link between maternal diet and the development of childhood allergy disorders, but the results have been mixed. In the protection of allergic disorders, duration of breastfeeding rather than exclusivity may be significant.

Does the Diet of the Mother During Pregnancy Have an Impact on the Offspring’s Risk of Allergic Diseases?

The foetus’s first nutritional exposure to allergens comes from the mother’s diet when she is pregnant. The majority of research to date has found a shaky link between maternal nutrition during pregnancy and the onset of childhood allergy disorders.

A Cochrane comprehensive review found no evidence to suggest allergen avoidance or nutrient supplementation during pregnancy as a way to protect offspring from allergy disorders.

However, research from mothers who eat peanuts and tree nuts suggests that foetal allergen exposure through the mother’s diet may actually raise tolerance and lower the likelihood of developing these juvenile food allergies.

As a result, more research is needed to determine the impact of maternal nutrition in the development of food allergies in children.

Fatty Acids (FAs)

It’s debatable whether there’s a link between early maternal polyunsaturated fatty acid (PUFA) consumption and childhood allergy disorders. A higher n-6:n-3 fatty acid ratio during pregnancy may cause the T-helper shift from type 1 to type 2, increasing the incidence of allergic rhinitis in kids.


Antioxidants (vitamin E, flavonoids, selenium, and copper) may be advantageous to foetal lung development and respiratory health later in life, reducing the incidence of wheeze.

Vitamin D is an essential nutrient

There is no apparent link between vitamin D levels in pregnant women and the development of atopic illnesses in children. As a result, prenatal vitamin D supplementation is not currently suggested for the prevention of allergy illness in offspring.

We already know that 25-hydroxyvitamin D3 levels in cord blood are linked to decreased mononuclear cell cytokine responses to allergens and a lower risk of eczema in the first year of life. Furthermore, higher vitamin D intake during pregnancy has been linked to a lower incidence of wheezing and eczema in 16–24 month old kids.


A new prospective birth cohort study found a link between prenatal maternal food intake and the incidence of allergy disorders in offspring by the age of three years. Green vegetables, eggs, and cereals were found to protect against respiratory allergy disorders, but higher preconception meat diet was linked to an increased risk of wheeze, allergic rhinitis, and eczema.

A high-vegetable diet during pregnancy was linked to a lower risk of childhood asthma in offspring in a prior prospective cohort research.

Is Human Milk Protective in Breastfeeding?

Human milk (HM) is currently recommended as the “gold standard” for baby nutrition by current guidelines. Breastfeeding prolongs the contact with the immune system of the mother and may alter oral tolerance and allergy risk in children. Pivotal research clearly indicate the importance of nursing for both short-term and long-term baby health.

Nonetheless, the data for the involvement of HM in allergy prophylaxis is weak and contentious. This is owing to the absence of randomised controlled trials with precise information on the maternal diet in nursing and the lack of standardised definitions of allergy outcomes.

Complementary Feeding: Does the Order in Which Food Is Introduced Affect the Risk of Allergies?

In the past, it was common practice to postpone the introduction of potentially allergenic foods, based on the premise that gut anatomical and functional immaturity, as well as greater permeability, indicate an increased risk of allergic sensitization.

But in case breast feeding is not available, and you must have to find a complementary way, then what will you do? What will you feed? The best and popular complementary food is cereals with proper iron and other things.

You can also feed them verities of things like Purred milks, tofu, fish and many more things which will give the child a healthy body. These type of foods may not be the perfect foods for a baby, but these is the ones which will give your child a proper nutration, in replacement of breast feeding.

Final Words: –

It’s still unclear whether early dietary factors play a role in the development of allergies later in life. Many dietary components have been proposed to alter the susceptibility to allergy disorders by changing the gut microbiota composition and boosting allergen tolerance from prenatal life through infancy.
