It is just heart-breaking to see your little one suffer from allergies – whether it’s food allergies, asthma, allergic rhinitis (hay fever), or atopic dermatitis (eczema).

Food allergy

A food allergy reaction occurs when a person’s immune system overreacts to a food (or a substance in food) and triggers a protective response. Allergies tend to run in families; errors in a gene that helps regulate the immune system are associated with higher rates of allergies, but it’s difficult to predict whether a child will inherit a parent’s food allergy.

While any food can cause the allergic reaction, there are some common food allergens amongst children: eggs, milk, peanuts, tree nuts, fish, shellfish, wheat and soy.
If your baby is already diagnosed to be allergic to one of the above, here are some tips:

MilkUse breast milk, soy milk or H.A formula
EggAvoid egg and egg products and food items that may contain eggs.
Read the food labels and avoid contamination.
Use alternatives to eggs in recipes.
Anyone diagnosed with an allergy to either egg whites or egg yolks should avoid eggs altogether; it is not possible to completely separate the white from the yolk
FishAvoid fish products and food items that may contain fish (ie. Worcestershire sauce and Caesar dressing).
Read the food labels and avoid contamination.
shellfishAvoid shellfish (ie. shrimp, lobster and crab).
Read the food labels and avoid contamination.
PeanutsAvoid peanuts and peanut products.
Avoid foods that may contain peanuts.
Be extra careful when eating Asian and Mexican food and other cuisines in which peanuts are commonly used.
Read the food labels and avoid contamination.
Avoid “arachis oil” (which is another term for peanut oil)
Some food (ie Chia seeds) may cause the same allergic reaction.
Tree nutsAvoid tree nuts and tree nut products.
Avoid foods that may contain nuts.
Read the food labels and avoid contamination.
Tree nut oils, which may contain nut protein, can be found in lotions, hair care products and soaps; those allergic to tree nuts should avoid using these products.
SoyAvoid soy, soy products and food items that may contain soy.
Avoid foods that may contain nuts.
Read the food labels and avoid contamination.
WheatAvoid grains that contain wheat such as cereals, pasta, crackers, and food items that may contain wheat like some hot dogs, sauces and ice cream.
Read the food labels carefully to avoid cross-contamination during the manufacturing process.
Choose wheat free products such as corn, rice, quinoa, oats, rye and barley.

Breastfeeding, complementary food and allergy

Breastfeeding can certainly help to decrease the risk of infection and allergy, but it is also important to know when to introduce complementary food. WHO recommends exclusive breastfeeding up to 6 months, which is crucial in developing countries to eliminate the risk of infection. But with access to clean food and careful feeding practices, studies (1, 2) have shown that starting on solids during 4-6 months did not increase their risk of hospitalization for diarrhoea or risk of infection.
If the baby’s digestive system is ready for solid food, parents can start complementary food from 4-6 months if they desire. It’s recommended to introduce a variety of pureed natural foods in a small quantity, with no additional flavouring and seasoning. Studies have found that introducing wheat and eggs between 4 and 6 months had a decreased risk of allergy, compared to introducing them after 6 or 10 months. A study also showed a lower risk of type 1 diabetes when cereals were introduced between 4 and 6 months.

Probiotics and allergy

The occurrence of allergy is also associated with the presence of probiotics in the intestine. Lactobacillus can reduce the body’s allergic reaction by activating T cells and regulating the balance of Th1 / Th2. If pregnant women or both husband and wife have a family history of allergies, the chance of giving birth to children with allergies is higher. Many studies have found that, instead of supplementing the infants with probiotics, mothers who took probiotics during the trimester and continued to breastfeeding had a lower chance of giving birth to children with an allergy.

There are thousands of different types of probiotics and some of them have been proven to lower the risk of certain allergies. But there are so many probiotics products on the market, which one should you choose?
By taking Lactobacillus rhamnosus (LGG, LC705, F19, LPR and HN001), Lactobacillus acidophilus La-5, B. bifidum BGN4, B. lactis AD011, Bifidobacterium animalis subsp. lactis Bb-12 and/or B. longum BL999 from the trimester, it can help reduce the incidence of eczema in children by 20-50%.

It’s also shown that supplementation of synbiotics (a mixture of prebiotics and probiotics) with young children (over 1-year-old) can reduce the incidence of atopic dermatitis. The probiotics in the studies included Lactobacillus fermentum LF-PCC, Lactobacillus acidophilus DDS-1, Bifidobacterium lactis UABLA-12, Lactobacillus salivarius, Lactobacillus rhamnosus LCS-742, and Bifidobacterium infantis M63.

L. paracasei LP33 was confirmed to be effective in improving allergic rhinitis, but in 2011, Dr. Xu Qingxiang discovered the probiotic Lactobacillus paracasei LP BRAP-01, which is not only more effective but also able to improve the symptoms of asthma, atopic dermatitis, IBS, drug allergy, food intolerance. Moreover, a study done in 2012 showed that Lactobacillus lactis LJ EM1 can effectively improve the symptoms of seasonal rhinitis.
Although probiotics have a lot of advantages to us, it must be taken cautiously by people who have low immunity, and also need to follow the recommended amount on the food label.
