What does calcium do?

Calcium is the most abundant mineral in the body.2 While this mineral is mostly known for its role in keeping our bones and teeth strong, it also helps with several other bodily functions, including:

  • Blood clotting

  • Sending and receiving nervous system signals

  • Muscle contraction and relaxation

  • Hormone release

  • Maintaining a normal heartbeat1,2

Getting enough calcium is critical from infancy through adulthood. When you’re not getting enough of this mineral in your diet, the body pulls calcium from your bones when it needs more.1 This means that low calcium intake over time will cause bones to weaken, putting a child at risk for rickets and an adult at risk for osteoporosis.1

How much calcium is needed?

Below are the Recommended Dietary Allowances (RDAs) for calcium:

  • Babies 0 – 6 months: 200 mg

  • Infants 7 – 12 months: 260 mg

  • Children 1 – 3 years: 700 mg

  • Children 4 – 8 years: 1,000 mg

  • Teens 9 – 18 years: 1,300 mg

  • Adults 19 – 50: 1,000mg

  • Pregnant and breastfeeding women: 1,000mg1

Food sources of calcium

While most people link calcium with dairy, in addition to dairy there are many other food sources of calcium to include in the diet.

Getting a variety of calcium-rich foods can also increase the amount of nutrients consumed. For example, plant foods high in calcium, such as greens, beans, and nuts, are also high in vitamins, minerals, and powerful antioxidants.

Below are some foods that can help meet calcium needs. Be sure to only provide foods and food textures that are appropriate for your child’s age and stage:

  • Dairy (milk*, yogurt, cheese)

  • Fortified foods and beverages such as: whole grain cereal, whole wheat bread, orange juice, tofu, nondairy beverages such as soy and almond milk, tofu

  • Canned salmon and sardines, both with bones

  • Spinach, turnip greens, kale, Chinese cabbage, broccoli

  • Soybeans, chia seeds, pinto beans

*Children under 1 year should not drink cow’s milk. Read more here: How Do I Introduce Milk to my Toddler

Certain substances like oxalic acid (found in spinach, collard greens, sweet potato, and beans) as well as wheat bran prevent calcium absorption to some degree.5,6 But know that these foods provide many other nutrients that are important for health, so it’s important to keep them in our diet and simply aim for many sources of calcium throughout the day.

Calcium in your baby and toddler’s diet

While breastmilk and infant formula usually provide all the calcium needed for babies, it is important to begin offering calcium-rich foods once your little one is ready for solids and throughout their childhood.4,7

In fact, childhood through the teenage years is the most important time for building good bone mass for life.7 So getting in the habit of eating foods rich in calcium from an early age is important for long term bone health.

Dairy foods high in calcium are also typically high in protein and fat, both of which are also important for your baby and toddler. Feeding your little one a healthy and varied diet full of whole foods will help provide them with not only the calcium they need a but also many other nutrients.

One fact to keep in mind as you plan your and your children’s diet is that the body absorbs calcium best when it’s spread out through the day, and not eaten all at once.3 3

Tips to getting enough calcium

Provide a variety of calcium-rich foods to your baby or toddler.

The goal is to introduce several different food sources of calcium throughout the day to not only help build your baby and toddler’s taste preferences, but also to aim for a good calcium intake average over the week.

Make sure you provide foods and textures that are appropriate for your baby’s age and oral motor skills.
