When can babies have chestnut?

Chestnut, when finely ground or shared as a thinned-out butter or paste, may be introduced as soon as baby is ready to start solids, which is generally around 6 months of age. Take care to modify whole chestnuts, chopped chestnuts, candied chestnuts, and globs of chestnut paste, as they present an increased risk of choking.

Chestnut trees grow across the Northern Hemisphere, producing fruits with a smooth, brown shell encasing the plant’s edible part: a pale, dense seed. Traditionally a source of food, oil, and wood in the Americas, the continent’s native trees were nearly wiped out by a blight in the 1900s. Today, most edible chestnuts in the Americas are imported from East Asia and Europe. Note that chestnuts are unrelated to horse chestnuts (which can be toxic) and water chestnuts—a type of edible tuber.

How do you serve chestnuts to babies?

Every baby develops on their own timeline, and the suggestions on how to cut or prepare particular foods are generalizations for a broad audience.

6 months old +:

Grind cooked and peeled chestnuts with a mortar and pestle or food processor, or grate with a microplane until no large pieces remain. Depending on how the chestnut was cooked, this may resemble powder or paste. From there, sprinkle or mix into other food as you wish. Alternatively, use chestnut flour to make pancakes or muffins. Just start slowly: chestnuts are high in fiber and may lead to gas or even a poop blowout. If you’d like to use chestnut paste, minimize choking risk by thinning it with water, breast milk, or formula until it is saucy and smooth with no clumps. Stir the mixture into a soft, scoopable food or drizzle on other foods. Avoid candied chestnuts, as they pose a high risk of choking.

Grind cooked and peeled chestnuts with a mortar and pestle, microplane, or food processor until no large pieces remain and sprinkle on foods as you like. Alternatively, incorporate chestnut flour in pancakes or muffins. If you’d like to use chestnut paste, minimize choking risk by thinning it with water, breast milk, or formula until it is saucy and smooth with no clumps. Stir the mixture into a soft, scoopable food or drizzle on other food.

To prepare pre-packaged chestnuts for babies, slice thinly or flatten them between your fingers until they break apart into pieces, which should be soft and crumble easily with pressure. Serve directly on the tray or table to encourage baby to eat the pieces one at a time (rather than serving in a bowl, which enables baby to scoop up many pieces at once). Avoid candied chestnuts, as they pose a high risk of choking.

12 months old +:

To serve pre-packaged, cooked chestnuts (which should be soft and crumble easily with pressure), simply remove the chestnuts from the package and either slice them thinly or flatten them between your fingers until they break apart into pieces. If you’d like to serve chestnuts cooked at home, cut the cooked, peeled chestnuts into thin slices or smash until they break apart into pieces. Make sure each piece you offer is soft and crumbles easily with pressure. If the pieces don’t crumble easily, finely grind them instead. Serve directly on the tray or table to encourage the toddler to eat the pieces one at a time (rather than serving in a bowl, which enables a child to scoop up many pieces at once). Avoid candied chestnuts, as they pose a high risk of choking. At this age, toddlers may also be ready to try chestnut paste or nut butter without thinning it with water or other liquids. Make sure the nut butter is thinly spread and offer milk or water in an open cup to help wash down any sticky pieces.

24 months old +:

At this age, many toddlers are ready to learn how to eat a whole cooked, peeled chestnut without any modifications. You may want to start with pre-packaged cooked chestnuts, as they can be considerably softer than nuts cooked at home. To begin, model taking a bite and chewing. Hold the chestnut in front of the child and say, “This one needs a lot of chewing.” Take a single bite with your front teeth, and exaggerate how you move the food to your molars to chew. After thoroughly chewing it, open your mouth to show them your chewed food, then swallow it. Once you feel the child is ready, offer them a chestnut and let them pick up the food and try eating it on their own. You can also hold the chestnut as the child takes a bite to prevent them from putting the entire thing in their mouth. As always, stay within arm’s reach of the child in case help is needed.

3 years old +:

Continue sharing finger food made with chestnut flour and soft, scoopable food with sprinkles of finely grated or ground-up chestnut, and finger food with nut butter or chestnut paste. At this age, toddlers may also enjoy trying candied chestnuts, though remember: they present a high risk of choking for young children, so wait to share them until the child has developed mature eating skills. These skills include taking small bites with teeth, moving food to the side of the mouth when chewing, chewing thoroughly before swallowing, not stuffing food in the mouth, and finally, demonstrating the ability to identify and spit out food when needed. Once you are confident a child has honed these skills, teach them how to eat a candied chestnut that is soft and chewy.

After practicing nuts with a toddler, make sure their mouth is clear before taking them out of the high chair. Never allow the toddler to walk around with nuts or nut pieces in their mouth.

When coaching how to safely chew challenging foods, it is important to help the child stay engaged with the task. That is why you and the child should be seated and focused on the task and not talking, singing, laughing, dancing, or moving around. There is an increased risk of choking when sharing challenging foods with a highly animated child who is talking, yelling, or singing.

Is chestnut a choking hazard for babies?

Yes. Chestnuts are firm, round, slippery, and chewy or crumbly when cooked, which are qualities that increase the risk of choking. To reduce the risk, prepare and serve chestnuts in an age-appropriate way, as described in the How to Serve section. As always, make sure you create a safe eating environment and stay within an arm’s reach of baby during meals. For more information on choking, visit our section on gagging and choking and familiarize yourself with the list of common choking hazards.

Learn the signs of choking and gagging and more about choking first aid in our guides, Infant Rescue and Toddler Rescue.

Is chestnut a common allergen?

No, despite being categorized as a tree nut, chestnut is not classified as a Global Priority Allergen by the World Health Organization. In fact, reports of primary chestnut food allergy are quite rare.

However, chestnut is known to frequently share cross-reactive proteins with avocado, banana, kiwi, and latex. This is known as latex-fruit syndrome. In case of latex-fruit syndrome to chestnut, symptoms can range from mild oral allergy (short-lived itching, tingling, or burning in the mouth) to severe, systemic reactions.

Individuals who have chestnut allergy, but are not allergic to latex, may also experience sensitivities to mugwort pollen and peach.

As you would when introducing any new food, start by offering a small quantity for the first few servings. If there is no adverse reaction, gradually increase the quantity over future meals.

Is chestnut healthy for babies?

Yes. Chestnuts offer carbohydrates and fiber, in addition to folate, magnesium, potassium, zinc, and vitamins B6, C, and K. Together, these nutrients provide energy to fuel baby’s growth, play, and exploration. They also support gut microbiome diversity, brain development, electrolyte balance, metabolic processes, immune function, and blood clotting.

★ Tip: To save time, choose pre-cooked and vacuum-sealed chestnuts when they are available. If you want to prepare fresh chestnuts, give them a shake before purchasing. Fresh chestnuts should not rattle, a sound that indicates that the seed has dried out.

When can babies have sweetened chestnut paste?

It is safe to add chestnut paste that has been thinned with water or another liquid to food as part of a varied diet when baby is ready to start solids, which is generally around 6 months of age. That said, it can be beneficial to wait until the child is older to regularly serve sweetened chestnut pastes and spreads. While an occasional taste of sugar is fine, regularly consuming excessive amounts of foods with added sugar can impact dental health over time.
