Food Products and Gaining Height - as part of the expert series by GeoBeats. Unfortunately, there is no one food product that will help you grow taller. Some of the things that you can ensure though, if you have children, or if you still are in the stages of development and growth, such as teenagers, you want to make sure that you are getting enough calories. Malnutrition can actually prevent you from growing to your fullest potential, but there is no one food in particular that is going to make you grow taller, especially if you are already an adult. You want to make sure that you are getting a balanced diet, full of calcium and Vitamin D, because those help your bones get stronger. But again, to reiterate, there is not one specific food that is going to magically help you grow taller.
