How to Prevent Food Allergies in Children


I’ve some natural remedies that I keep on hand for seasonal allergies, however meals allergy symptoms are in a distinct camp altogether. While seasonal allergy symptoms are annoying, meals allergy symptoms could be downright lethal. And an increasing number of households are being affected by them.

What Is a Food Allergy?

Food allergy symptoms happen when the physique produces a selected immune response to a sure meals. This immune response could be as delicate as irritation or as critical as anaphylactic shock.

Common meals allergy symptoms embody milk, egg, peanut, tree nuts, soy, wheat, fish, and shellfish. Milk, egg, and peanut make up 80 % of meals allergy symptoms.

Types of Food Allergies

Food allergy symptoms could also be IgE, IgG, or non-IgE-mediated (checked with a blood take a look at). When an allergy is IgE-mediated, IgE antibodies are launched. These antibodies stimulate proinflammatory cytokines which trigger the allergic response many take into account to be “true” meals allergy symptoms. This response could be life-threatening. This is why many youngsters are prescribed an auto-injector (epiPen) that they carry round in case of meals allergy reactions.

A extra controversial principle is that IgG may additionally play a component in meals allergy symptoms. An IgG-mediated response causes a delayed sensitivity to meals, in accordance to some analysis together with this 2007 study.

Other analysis, nevertheless, exhibits that the presence of IgG may very well sign a better tolerance of a meals later in life. One research revealed in the journal Pediatric Allergy and Immunology discovered an affiliation between excessive ranges of IgG4 antibodies to meals throughout infancy and tolerance to the identical meals later in life.

Food Allergy vs. Food Intolerance or Sensitivity

Food intolerances and sensitivities don’t contain the immune system. They often solely trigger digestive points, like in the case of lactose (dairy) intolerance. Food intolerances are often brought on by issues like:

  • enzymatic deficiencies
  • nutrient malabsorption
  • sensitivity to sure proteins or elements of food such as gluten, FODMAPS (a form of carbohydrate), or histamine

It could be tough to inform if a meals intolerance can also be an allergy although. You might not discover delicate irritation or eczema (or acknowledge the connection). It’s tough to know if a response is an intolerance or a non-IgE mediated meals allergy. This is one purpose that many individuals use the phrases “allergy” and “intolerance” interchangeably.

You can have an allergy pores and skin take a look at carried out to verify for an immune response, however preserve in thoughts that they aren’t all the time correct. Many households don’t hassle with a pores and skin prick take a look at for that reason and deal with their signs as in the event that they may very well be both an allergy or an intolerance.

What Causes Food Allergies?

If you ask round, most individuals would agree that meals allergy symptoms are growing in prevalence. Most of us don’t have a grandparent with any meals allergy symptoms, however many people have youngsters with them.

In our podcast interview, Dr. Katie Marks-Cogan, a board-certified allergist (and mother) defined:

We’re seeing an increase and it’s really fairly drastic. Currently, it’s estimated that about 8% to 10% of youngsters in the United States have a meals allergy. So for those who break that down, that’s about 1 in 13 youngsters. And if you consider school-aged youngsters, that’s two youngsters per classroom.

She additionally mentions that the speed of peanut allergy has virtually tripled over the previous couple of many years. Cow’s milk and egg are different frequent offenders and are the toughest to keep away from since they’re in so many meals.

Food Allergy Theories

Because of this enhance in meals allergy symptoms, you is perhaps questioning what we’re doing in a different way now that we weren’t doing in the previous. Some of the next theories handle that query (and a few don’t). Here are a number of the most typical theories on meals allergy symptoms:

  • Food Allergen Avoidance – The recommendation we’ve been getting for a very long time is to keep away from giving infants probably the most extremely allergenic meals early in life, and delaying previous age one or two. Now there may be proof that avoidance was a significant a part of the issue.
  • Dual-Allergen Exposure Hypothesis – One principle that has been gaining traction currently is that publicity to meals allergens by way of the pores and skin could also be partly to blame for meals allergy symptoms. This 2012 study discovered that this can be true whereas early oral publicity can scale back the chance.
  • Nutrient Deficiency – There have been research suggesting that meals allergy symptoms could also be a response to nutrient deficiency corresponding to vitamin D and omega-3s (extra on this under).
  • The Hygiene Hypothesis – Much analysis in the previous a number of years has discovered that being too clear can have a detrimental impact on the physique. The principle states that not being uncovered to pathogens early can weaken or skew the immune system so meals allergy symptoms are extra possible. This is one purpose I don’t use antibacterial products round the home (although 6 youngsters = loads of dust and micro organism coming in the home).
  • Probiotics – Piggybacking on the hygiene principle, one other principle is that lack of wholesome intestine micro organism performs a component too. For instance, a 2009 research carried out on infants discovered that decreased ranges of sure probiotics in the primary two months of life made infants at larger threat for meals allergy symptoms later.

It’s irritating, however on the finish of the day, none of those theories absolutely explains meals allergy symptoms or why they’re on the rise. We simply don’t know why meals allergy symptoms develop. This is one purpose that treating and stopping them is so advanced.

However, new analysis has given us a clue on how to stop meals allergy symptoms by altering the way in which we introduce new foods to babies.

Science-Based Ways to Reduce the Risk of Food Allergies

The outdated knowledge was to keep away from giving infants probably the most extremely allergenic meals till after their first birthday. It’s what I did for a number of of my infants, based mostly on the going recommendation on the time.

But brace your self… new analysis exhibits that the alternative is true! In truth:

The earlier a baby is uncovered to allergenic meals, the decrease the chance of getting meals allergy symptoms. 

Here’s a rundown of the breakthrough analysis behind the change:

  • The LEAP research – This UK-based research was the primary randomized trial to research stopping meals allergy symptoms in a big group of high-risk infants. Results reported in 2015 discovered that peanut allergy symptoms had been 81% much less possible if the kid ate peanut protein between 4 and 11 months of age.
  • The EAT researchAnother study found that introducing allergens corresponding to peanut, egg, and milk between 3 and 6 months lowered allergy symptoms later by 67%. However, research members may solely obtain 50% compliance with protocol, indicating that early and sustained introduction was tough to obtain at such a younger age. The research additionally confused that the advice was nonetheless to completely breastfeed in the course of the first six months of life.
  • The PETIT researchIn this study, 4- to 5-month-old infants with eczema who got egg protein had been 79% much less possible to develop egg allergy symptoms later.

It’s thrilling to have some onerous information uncovering the causes of meals allergy symptoms and what to do about it, however how dad and mom can act on these (slightly advanced) findings is much less clear.

A Holistic Approach to Preventing Food Allergies

This new info doesn’t give us all of the solutions however it is a vital piece of the puzzle when it comes to decreasing the pattern of rising meals allergy symptoms in youngsters.

What the research do inform us with some confidence is that in most circumstances there isn’t a obvious profit to delaying in the introduction of allergenic meals, and in truth they need to be given to infants:

  1. Early (as early as 4-11 months)
  2. Frequently (at the least 3x every week)
  3. Consistently (for a number of months)

When Is “Early”?

As tips and follow meet up with the analysis, tips differ about the suitable age to introduce these meals.

Let me be clear: I don’t suggest feeding infants strong or pureed meals earlier than 6 months of age (and the World Health Organization agrees) for just a few causes.

  • Babies don’t lose the tongue thrust reflex till 4-6 months of age. This reflex means if meals enters their mouth they routinely push it out with their tongue. This is a protecting mechanism.
  • Babies who can’t sit up on their very own shouldn’t have strong meals in their mouths (even purees — it’s a choking hazard). Many infants can’t sit up on their very own till at the least 6 months of age.
  • Solid meals displace breastmilk. Meaning child misses out on a number of the dietary and immune-building advantages of breastmilk.

The new analysis is clearly telling us although that early introduction, not avoidance, delivers higher outcomes.

So, what’s a dad or mum to do?

Ready, Set, Food!

It’s value mentioning that there’s one firm bridging the hole between this analysis and placing it into follow. An allergist-mom involved about this difficulty teamed up with an unbelievable panel of consultants and allergists to develop a easy powdered complement that may be added to child’s bottle (both expressed breast milk or system).

It’s called Ready, Set, Food! and it’s natural, non-GMO, and comprises small quantities of egg, dairy, and peanut (the 3 high allergens).

(Personally, until I had to bottle feed I wouldn’t categorical breast milk in order to do that, as there may be some nutrient loss. I’d wait till the introduction of strong meals and add it at the moment, however do your personal analysis about what’s proper for your loved ones.)

What’s good about Ready, Set, Food! is that it makes it very simple on dad and mom (all the time a fan of that!) to start with very small quantities of allergenic meals with out the hazard of intestinal upset or choking by feeding strong meals too early. It additionally makes it simple to be constant and frequent with publicity in what is usually a busy and sleep-deprived stage of life.

Other Things to Try

Early publicity to allergens in fastidiously calculated doses are a technique to assist scale back the prospect of allergy symptoms. There are another way of life elements that may assist to optimize as effectively. While not all of those are positively going to assist, they’re typically good to your health anyway, to allow them to’t harm.

  • Gut therapeutic – Because a lot of the immune system resides in the intestine, it is smart to make it as wholesome as potential. Babies inherit mother’s intestine health, so starting with your own gut health is an efficient first step. Breastfeeding, if potential, is an efficient manner to get child off to a superb gut-health start.
  • Eat allergenic meals whereas pregnant and breastfeeding –  It would make sense that this may very well be useful since we all know that infants get their first style of meals from amniotic fluid and breastmilk. At this level, researchers aren’t satisfied mother’s diet during pregnancy and breastfeeding impacts the infant’s allergy growth. However, one research in mice exhibits that this prenatal and breastmilk publicity can scale back meals allergy symptoms.
  • Immune assist – Allergies are typically considered a misfiring or overreaction of the immune system. Making certain the immune system is correctly developed might assist. Since we all know child inherits a few of his immune system from mother, it’s not a foul concept to make sure that your immune system is at its greatest. The suggestions in this publish might help support your immune system. However, there isn’t a analysis to assist this concept.
  • Vitamin D – Studies counsel that infants with low vitamin D ranges are at larger threat for meals allergy symptoms. Boosting your own vitamin D throughout being pregnant and breastfeeding might help. Vitamin D drops after delivery are additionally a sensible choice however all the time speak to a health care provider earlier than giving a child any complement.
  • Omega-3 fatty acids – In one research, ladies who took fish oil dietary supplements throughout being pregnant had a 30 % decrease threat of their youngster creating egg allergy symptoms. Again, verify with a health care provider and ensure to choose a high quality omega-3.

As talked about, there isn’t a lot proof that the above recommendation will assist keep away from meals allergy symptoms. But on the identical time, most of this recommendation has no drawbacks and is nice common health recommendation, so it could possibly’t harm to attempt.

How to Introduce Allergens Early

Always seek the advice of your youngster’s healthcare supplier earlier than making any selections to introduce meals. If you’re planning on introducing allergenic meals at 6 months of age listed here are some suggestions for doing it:

  • Start with milk, egg, and peanut as these are the more than likely allergens.
  • Offer very small quantities of 1 meals at a time. Then and work your manner up to bigger quantities.
  • Offer them usually. Once isn’t sufficient. Baby wants time to “learn” about these meals.
  • Consider utilizing Ready, Set, Food!’s system which provides child a really small quantity of the very best allergenic meals (separately). It makes giving child these meals (in small quantities and regularly) simple for you.

While you start feeding child these meals, all the time concentrate on any allergic reactions that pop up.

Allergy Signs to Look For

Even although you’ll be feeding very small quantities of those meals, child should have a response. Here are some allergy signs to search for:

  • Digestive points like vomiting or diarrhea
  • Hives, welts, or different pores and skin rashes
  • Face, tongue, or lip swelling
  • Coughing or wheezing
  • Trouble respiratory
  • Loss of consciousness

Severe reactions require medical care. If you’re feeling your youngster is having a extreme allergic response, name your youngster’s physician or 911.

Preventing Food Allergies in Children

Food allergy symptoms, particularly in youngsters, are on the rise. We don’t know but what’s inflicting it. But the latest analysis exhibits us that early introduction to allergenic meals is one of the simplest ways to stop meals allergy symptoms.

What I Would Do

For the primary 6 months of life, all child wants nutritionally is breastmilk or system. If I had been already bottle-feeding, I’d use Ready, Set, Food! as early as 4 months of age to match the time window really helpful by the analysis.

Personally, I wouldn’t categorical milk or bottle feed only for this objective since breastfeeding has many advantages of its personal, however I encourage everybody (particularly these with a household historical past of allergy symptoms) to do their very own analysis and make the most effective determination their household.

At 6 months of age when strong meals could be launched, I would come with small quantities of allergenic meals immediately (together with nutrient-dense foods like bone broth, liver, etc.) and add Ready, Set, Food! as effectively to preserve the introduction of allergenic meals constant.

Have you tried feeding allergenic meals early? What was your expertise?
