Soy Milk 101
Getting to know soy milk
Of all the plant milks on the shelf, soy is the one nutrition experts point to as the closest match to cow's milk. It is creamy, mild, and works anywhere dairy milk does — on cereal, in smoothies, in baking, or in a cup.
A few good things to know
It is the highest-protein plant milk
Around 7 to 9 grams of protein per cup — similar to cow's milk, and far more than almond, oat, or rice milk.
Fortified kinds match cow's milk
Look for added calcium, vitamin D, and B12. Fortified soy is the one plant milk the U.S. dietary guidelines count in the dairy group.
It is a complete protein
Soy protein has an amino-acid profile close to animal protein, supplying all nine essentials your child needs to grow.
It is mild and swappable
A neutral, creamy taste that pours over cereal, blends into smoothies, and bakes just like dairy milk.
Easy ways to use it
Over cereal or oatmeal. A creamy, protein-rich pour that kids won't be able to tell from dairy.
Blended into smoothies. Adds body and a quiet protein boost to any fruit smoothie.
In baking and cooking. Swaps one-for-one for dairy milk in pancakes, muffins, and sauces.
Warm, as a bedtime cup. Gently warmed with a little vanilla or cinnamon for a cozy, comforting drink.
READING THE LABEL LIKE A PRO
Two words to look for: unsweetened and fortified. Unsweetened keeps added sugar down, and fortified means calcium, vitamin D, and B12 have been added so your child gets the nutrients that make milk worthwhile. A quick shake before pouring helps, since calcium can settle at the bottom.
Which milk for which age: for children 12 months and up, fortified unsweetened soy milk is a well-regarded stand-in for cow's milk. It is not suitable as a main drink for babies under one, who need breast milk or formula. If your child has a soy allergy, ask your pediatrician about pea milk as another higher-protein option.
