When can babies have nutritional yeast?
Can babies have nutritional yeast?
Babies can have nutritional yeast from about 6 months as a small sprinkle mixed into food. Nutritional yeast adds a savory, cheesy flavor and many brands are fortified with B vitamins, including B12. Choose a brand without added salt and stir it into moist foods rather than dusting it dry.
How to serve nutritional yeast by age
Shapes and textures change as your baby’s grasp and chewing grow.
6 months
Stir a small pinch, up to about half a teaspoon, of nutritional yeast into smooth foods like mashed potato, lentil puree, mashed avocado or a blended pasta sauce. Mixing it into moist food keeps the flakes from sticking to the mouth.
7–8 months
Keep stirring a pinch of nutritional yeast into lumpier mashes, soft scrambled eggs, lentils or soft pasta. You can also roll soft steamed vegetable pieces in a little nutritional yeast so they are easier to grip.
9–12 months
Sprinkle nutritional yeast into pasta, rice, roasted vegetables or tofu, or use it to coat soft finger foods like steamed broccoli florets so they are easier to grip.
12 months +
Toddlers can have nutritional yeast in cheesy-tasting sauces, on popcorn alternatives like puffed snacks, in soups and on toast. A teaspoon or so at a meal is plenty.
Why it’s good
Fortified nutritional yeast gives babies B vitamins, including B12, thiamine, riboflavin and folate, plus some protein, zinc and fiber. It is especially helpful for vegetarian and vegan families as a B12 source, but it should not be the only one. Check the label, since unfortified brands contain little B12.
Safety notes
- Mix nutritional yeast into moist foods. Dry flakes dusted on food can be inhaled or stick in the mouth and make babies cough.
- Some brands add salt or seasoning. Choose plain, unsalted nutritional yeast.
- Fortified brands are very high in some B vitamins, so stick to small amounts and avoid giving it alongside multiple fortified supplements without asking your pediatrician.
- Nutritional yeast can be made in facilities that process wheat or other allergens. Read the label if your baby has allergies.
- Nutritional yeast is high in fiber and can cause gas if your baby eats a lot, so start small.
A low-allergy food, still worth watching
Nutritional yeast is not a common allergen, but rare yeast allergies have been reported. Some products are processed with wheat, so check the label, and watch for hives, vomiting or swelling the first few times.
