So you’ve started the weaning process and you’re looking at what foods might be great weaning foods. You look at the baby food aisle and you see green beans as a first weaning food. But something doesn’t feel quite right…

Green Beans?!

There’s nothing like questioning to be sure that what you’re doing is right, so let’s take a look at the science behind it. Is there any chance that your little one can be allergic or even intolerant of green beans?

Most babies will eat pretty much anything you give them, but it’s important to be aware that some foods can cause allergies. And one of the more common early food allergies is that of the legume family – which includes green beans. Other common allergies include dairy allergy, fish allergy and soy allergies.

When can babies have green beans?

Green beans are one of the first vegetables that many spoon-fed infants try. You can start them whenever your child begins solids, which is usually around 6 months. They can be introduced to babies starting at 6 months old by mashing them up with breast milk, formula or water

That is also true for newborns who are introduced to solids for the first time through baby-led weaning, a method that offers meals in the form of soft, gummable finger foods rather than purées. If you’re experimenting with baby-led weaning, wait at least 6 months before introducing green beans in finger food form. At that point, your child is more likely to be able to feed himself.

Can children be allergic to green beans?

Yes, but rest assured your little one is unlikely to be allergic to green beans, allergies are very rare.

However, if they are allergic to peanuts they may also be allergic to green beans. Peanuts are technically not a nut (who knew!) but a legume, like green beans. So as part of the same family, if your child (or even close family members) have a peanut allergy then they may well have a green bean allergy. Peanuts are considered a major food allergen but this does not mean you will have a full legume allergy.

The legume family includes:

  • Lentils Chickpeas
  • Green peas
  • Black-eyed peas 
  • Kidney beans 
  • Haricot beans
  • Adzuki beans
  • Butter beans
  • Broad beans
  • Fenugreek
  • Cannellini beans
  • Flageolet beans
  • Pinto beans
  • Borlotti beans
  • Mange-tout 
  • Lima beans
  • French beans
  • String beans
  • Snap beans
  • Common bean
  • Navy beans

Just because your child may be allergic to one of these, does not mean they are allergic to the entire legume family.

What Exactly is an Allergy?

An allergy is the body’s immune response to something that it thinks has no right being in your body. The immune system tries to attack and remove this unwelcome invader (allergen). When the allergen is in your body for a long time, this immune response can lead to symptoms that are bothersome.

With green beans, some babies will have an allergic reaction where they will get an itchy mouth and/or stomach ache while others may end up with more of a skin rash – similar to how some adults react to poison ivy. In severe cases, a baby may get anaphylactic shock.

An Anaphylactic Shock is a medical emergency and can be life-threatening

The most common foods that cause allergies are eggs, peanuts, tree nuts, cow’s milk and shellfish. These will often cause rashes or stomach aches similar to how green eans can cause allergy symptoms.

Symptoms of Allergic Reactions or Food Allergy to Green Beans

Of course, you should still be aware of the symptoms of a food allergy (in this and other foods) and look for signs of an allergic reaction, especially if you’re feeding green beans for the first time.

If eating a green bean trigger allergic reactions as detailed below within a short time of eating (within a few hours), then your child has a food allergy:

  • Hives
  • Itching
  • Skin, lip or tongue swelling
  • Sneezing
  • Wheezing
  • Throat swelling or tightness or trouble swallowing
  • Nausea, vomiting, stomach pain or diarrhea
  • Trouble breathing

If your child experiences severe allergic reactions caused by any food then call your doctor straight away. If your child has a severe reactions then you might be given an epi pen going forward. You can discuss all of this with an allergy specialist.

Are green beans a common allergen?

As with any new dish, begin by offering a little portion on its own for the first couple of serves. If there is no negative reaction, gradually increase the amount over subsequent meals and don’t let them be eaten raw by any child under the ae of 12 months.

If your child does have an allergic reactions to any member of the legume family its vital you look at food labels when preparing foods. Most food allergies and common allergies will be listed on the label.

Raw green beans, which are too hard and rough for toddlers to gum or chew and can pose a choking hazard so don’t give your child these.
