Key Points

A wide variety of foods supports the immune system

Aim for variety rather than relying heavily on any one food. Foods like salmon, eggs, yogurt, beans, berries, leafy greens, and squash are safe for babies and healthy for the whole family.

Prepare food in an age-appropriate way to lower choking risk

Many immune-supporting foods—including nuts, seeds, berries, and raw hard vegetables—need to be modified to be safe for a baby’s age. Check the First Foods® database for how to prepare and serve each food safely.

No food can replace sleep, sunshine, and lower stress

Healthy habits for the whole family support the immune system alongside a varied mix of foods.

It's a good time to focus on eating well to support your family’s immune system. These foods are safe for babies and healthy for the whole family.

As with everything, aim to focus on a wide variety of foods and don’t overdo any one thing. If you are not sure how often or how to serve a food, see our First Foods® database.

*Remember that nuts should be finely ground and nut butters must be thinned out with water, applesauce, or yogurt to reduce the choking hazard.

Lastly, there’s no super food that can replace the power of sleep, sunshine, and stress reduction.
