Bone marrow may be introduced as soon as baby is ready to start solids, which is generally around 6 months old. 

Bone marrow is the jelly-like substance in the middle of animal bones, often a cow’s femur bones, but other bones are also used, from lamb to moose, and more. Humans have long enjoyed this food, rich in fat, flavor, and protein. In some dishes, the marrow is scooped or sucked straight from the bone, while in others, marrow bones are used to flavor soups and stocks from bulalo to phở.

Yes. Bone marrow is rich in fat, including omega-3 fatty acids, in addition to iron, selenium, and zinc, as well as vitamins A, B12, E, and K. Together, these nutrients support growth, development, healthy red blood cells, immune function, vision, skin health, blood clotting, and more.

No. Bone marrow, whether from cow, lamb, or other animals, is not a common food allergen, although allergic reactions to various red meats have been reported. Certain tick bites (mainly the Lone Star tick in the continental United States, but other ticks in different parts of the world), are associated with the development of an allergy to galactose-alpha-1, 3-galactose (“alpha gal”), a sugar which is present in all non-primate mammalian meat. This results in a delayed allergic reaction 3-8 hours after red meat or organ tissues (such as bone marrow) are consumed. However, some individuals with alpha gal allergy also react to small amounts of the sugar present in dairy products or gelatin from mammals. Alpha gal allergy is more prevalent in the southeastern United States, but is starting to become more common in other areas as the geographic distribution of the Lone Star tick expands.

As you would when introducing any new food, start by offering a small quantity for the first few servings and watch closely as baby eats. If there is no adverse reaction, gradually increase the serving size over time.

Yes. Bone marrow can contain globs of fat, which can be firm and slippery, qualities that increase the risk of choking. To reduce the risk, prepare and serve bone marrow 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.

Hay muchos alimentos que pueden ser excelentes opciones. Busca alimentos que permitan que el/la bebé se alimente solo/a fácilmente, que tengan bajo riesgo de ahogamiento y que ofrezcan los nutrientes que los bebés necesitan, como el hierro.
