NORFOLK, Va. (WVEC) -- From celebrity websites and diet books to popular Instagram feeds and clean eating blogs, it appears to be trendy to ditch dairy.

However, experts say going dairy-free has multiple downfalls -- and it may be downright dangerous -- especially for kids and young adults.

According to dietitian Jim White, soy milk and almond milk lack nutrients of real milk such as protein, calcium, and potassium, which is very important for your body to have.

Non-dairy substitutes can include oranges, spinach, and almonds. But in order to get the amount of calcium in one glass of milk, White says you need to eat nine cups of spinach, or four large oranges, or 92 almonds!

White suggests that some ways you can get milk in a child's diet is to serve it with a snack, include it in their smoothies, and in their cereal.
