Green Beans

Green beans, sometimes known as string beans, may be introduced as soon as baby is ready to start solids, which is generally around 6 months of age.

Green beans are snap beans—a sprawling family of legumes whose tender pods are eaten before their tiny seeds mature and swell from soaking up sun and water. Aside from green beans, there are bush beans, pole beans, string beans, and wax beans, to name a few. All trace back to the common bean that was cultivated by Indigenous people of Central and South America for thousands of years before colonizers took the seeds to Europe.

Yes. Green beans are rich in fiber, folate, and water, in addition to vitamins B6, C, and K. Plus, they offer a dash of iron, some magnesium, lutein and zeaxanthin, as well as a variety of antioxidants. These nutrients work together to support baby’s gut microbiome, hydration, brain development, metabolic processes, iron absorption, immunity, blood clotting, red blood cells, vision, and more.

No. Green bean allergies are rare, though not unheard of and, in theory, an individual can be allergic to any food. As you would when introducing any new food, start by offering a small quantity on its own for the first few servings. If there is no adverse reaction, gradually increase the quantity over future meals.

Yes. Green beans can be firm and, when cut into small sizes, are similar in size and shape to the trachea at this early stage in life, qualities that increase the risk of choking. To reduce the risk, prepare and serve green beans in an age-appropriate way as described in the How to Serve section. Worried about the small beans inside each pod? The act of munching on a green bean pod tends to smash and flatten the little beans inside, which decreases choking risk. You can also use the back of a fork to flatten the whole cooked green bean pod before offering to baby to further decrease the risk. As always, make sure you create a safe eating environment and stay within an arm’s reach of baby during meals.

No. Feel free to offer vegetables that contain nitrates (arugula, beets, cabbage, green beans, spinach, and squash to name a few) as part of a variety of foods in the diet. Nitrates are naturally-occurring compounds which, if consumed in excess, may negatively affect oxygen levels in the blood. That said, babies who are allowed to self-feed typically do not consume excessive amounts of solid food because they need lots of practice to learn how to eat it. Nitrates in vegetables are generally not a cause for concern, and the benefits of introducing these vegetables as part of a balanced diet typically outweigh the unlikely risk of excessive consumption.

To reduce nitrate exposure, avoid consumption of untested well water and take care with purees. When possible, avoid homemade purees made with higher nitrate vegetables that are stored for more than 24 hours and commercial purees not consumed within 24 hours of opening.
