Topic Breakdown
Do you have food allergies and you're concerned that your baby might as well? As a new parent myself, I know how stressful weaning a baby can be. In today's discussion, we're diving into how to best approach introducing common food allergens into your baby's diet.
First off, how common are food allergies amongst children, and are certain children more prone to having allergies? Well, 8 to 10% of all children under the age of 18 suffer from food allergies. If there's a family history of food allergies, asthma, or eczema, the chances of your child also having allergies is higher. In these cases, you should always consult your doctor before introducing common food allergens to your child. These would include things like nuts, peanuts, seeds, eggs, cow's milk, soy, foods that contain gluten such as wheat, barley, and rye, shellfish, and fish.
It's crucial to avoid any food if you're unsure about the ingredients and think it might contain something that your child is allergic to. Make sure to read food labels very carefully. Now, speaking more generally, if you're not aware of your child having a food allergy or a family history of food allergies, asthma, or eczema, beginning at the age of six months, you can start introducing these foods into your baby's diet. You should introduce them one at a time in very small quantities so that you can spot any possible signs of an allergic reaction. Serve nuts, peanuts, and seeds either crushed or ground.
New evidence shows that waiting to introduce nuts and hen's eggs beyond six to twelve months may actually lead to an increased risk of developing a food allergy. So, it's best to introduce these foods before your child turns one, unless you're advised otherwise by your health provider.
So, if your child is unfortunate enough to develop an allergic reaction, what might it look like? Your child's immune system, which is the body's system to recognize and fight off infections, produces antibodies. Antibodies are a type of protein that normally fights off infections. However, when a child has a food allergy, their immune system mistakenly treats a specific food as if it were a harmful invader, like a virus or bacteria.
The first time that your child eats the food they're allergic to, their immune system responds by producing a specific type of antibody called IgE. Upon eating the food again, these antibodies quickly recognize it, kind of like saying, "Hey guys, we recognize that there's a bad guy here," and then they send a signal to the immune system to release chemicals like histamine. This causes the symptoms of an allergic reaction.
Depending on the severity, symptoms can range from mild, like itching or a rash, to severe, like difficulty breathing or loss of consciousness. In essence, a food allergy in childhood is the immune system's overreaction to a food, thinking that it's harmful when it's not. This process usually happens quickly, sometimes within a few minutes of exposure to a particular allergen. Physical reactions can include hives, eczema, or a red itchy rash, a runny nose or eyes, wheezing or coughing, diarrhea, vomiting, or abdominal pain, as well as headaches. In severe cases, it can lead to anaphylactic shock.
Anaphylactic shock is the most severe, potentially life-threatening allergic reaction triggered by allergens, leading to a rapid onset of symptoms like difficulty breathing, a swollen face, hives, and a severe drop in blood pressure. If your child develops anaphylactic shock, you must seek emergency medical care immediately.
Because allergic reactions can develop over time, it's important to closely monitor your child. If you notice any of these reactions, try to note what substances they've recently been exposed to, even if they didn't have an adverse reaction to the same substance at an earlier time. You should always consult your doctor before reintroducing your child to the substance. If an allergy is confirmed, you'll have to be extremely careful to avoid exposing your child to that food. This may include physical contact or breathing in the substance, not just eating it.
You'll need to diligently check all food labels because many foods can contain traces of other substances. You'll also want to communicate your child's allergy to any caregivers and have a plan in place in case your child has a severe allergic reaction.
While there is little you can do to prevent your child from developing food allergies, some studies show that breastfeeding your baby for at least six months may help to prevent food allergies. On a more positive note, around 80 to 90% of children grow out of egg, milk, wheat, and soy allergies by the age of five. However, nuts and peanut allergies are typically lifelong.
