Study finds drinking more milk growing up is associated with increased height at 17
Drinking real dairy milk is especially important for growing kids, and new research suggests regularly drinking more milk throughout childhood is associated with an increase in teenage height, according to a new study in “The Journal of Nutrition.”1
Researchers followed more than 700 kids from the time they were born, analyzing their height and diet from ages 2-17, and found each additional glass of milk kids drank per day throughout childhood increased their height at age 17 by around 0.39 centimeters. That means the more milk kids drank regularly growing up, the taller they were. Water and other beverages, including 100 percent juice and sugar-sweetened beverages, didn’t have the same effect.
These findings add to a growing body of research that suggests regularly drinking milk during the growing years is associated with greater height in the teen years, while regularly skipping milk or drinking non-dairy milk alternatives, like almond or soy milk, is linked to shorter height.2, 3, 4
The 2015-2020 Dietary Guidelines for Americans recommend two cups of milk and milk products each day for kids ages 2-3, two and a half cups each day for kids 4-8 and three cups each day for kids 9-18. While it’s hard for kids to get nutrients they need to grow strong without milk in their diets, eighty-five percent of Americans fall short of these daily recommendations, which includes most children over 3 years old.5, 6
