5 Key Ways To Support Your Child’s Immunity, From An Integrative MD


Protein is critical for immune function, and inadequate protein can increase the risk of worse outcomes due to infection. Most proteins are also great sources of nutrients, such as B vitamins, omega-3s, and zinc, which the immune system also needs.

Most Americans consume adequate protein, but if you have a picky eater at home, or follow a vegetarian or vegan diet, you’ll need to keep a close eye on protein intake. 

Aim for about one gram of protein per kilogram of bodyweight, sourced from high-quality, clean animal proteins (grass-fed beef, naturally-raised poultry, or wild-caught fish). Plant-based options like nuts, seeds, beans or legumes are great, and you can also incorporate non-GMO soy or tempeh into dishes.
