Get Excited About Calcium-Rich Foods
What is calcium?
Calcium is a mineral found in many different foods and food groups and can also be available as a dietary supplement. You’ll even find calcium present in some medicines. Did you know that calcium is the most abundant mineral in the body? Interestingly enough, calcium plays a crucial part in all stages of our life. Our body needs calcium in order to maintain strong bones and to carry out many bodily functions.
What does calcium do?
Calcium is mostly stored (~99%) in bones and teeth, where it supports their structure and hardness. Bones undergo continuous remodeling, with constant absorption and deposit of calcium into new bone. The balance between bone absorption and deposit changes with age, which is why calcium requirements vary depending on age. The other 1% of calcium is needed for muscle contraction and for nerves to communicate messages between the brain and other body parts. Calcium also assists blood vessels to move blood throughout the body and to release hormones and enzymes that affect almost every function in the human body.
Research suggests that calcium, along with vitamin D, may have benefits beyond bone health, making them a perfect pair. Some studies suggest that this combination may protect against cancer, diabetes and high blood pressure. However, evidence of such health benefits is not definitive.
How much calcium do I need?
According to the National Institute of Health, the amount of calcium needed daily depends on your age and sex. Average daily recommended amounts are listed in milligrams (mg):
| Life Stage | Recommended Amount |
|---|---|
| Birth to 6 months | 200 mg |
| 7‑12 months | 260mg |
| 1‑3 years | 700 mg |
| 4‑8 years | 1,000 mg |
| 9‑18 years | 1,300 mg |
| 19‑50 years | 1,000 mg |
| Adult men | 1,000 mg |
| Adult women | 1,200 mg |
| Adults 71 years + | 1,200 mg |
The recommended upper limit for calcium is 2,500mg a day for adults 19-50. Anyone 51 and older, the limit is 2,000mg a day.
What types of foods contain calcium?
Your body does not produce calcium therefore it must be obtained through your diet. Consuming a diverse diet inclusive of all food groups ensures that you’re meeting your calcium requirements. Here are some calcium-rich suggestions:
- Dairy products, such as milk, yogurt and cheese
- Dark leafy green vegetables, such as kale, broccoli and Chinese cabbage
- Fish with edible soft bones, such as canned sardines and salmon
- Calcium is added to some breakfast cereals, fruit juices, soy and rice beverages, milk substitutes and tofu.
The body also needs vitamin D to absorb calcium. You can get vitamin D from canned salmon with bones, egg yolks, fortified foods and sun exposure. The Recommended Daily Allowance for vitamin D is 600 international units (15 micrograms) a day for most adults, according to the National Institute of Health.
Sources of calcium
Many people are not able to consume dairy products for one reason or another, or have opted to follow a plant-based lifestyle. Guess what? Good sources of calcium can be found in almost all food groups! This abbreviated list can help you mix and match specific calcium-containing foods throughout the day to reach your daily value (DV).
| Food | Milligrams (mg) per serving | % DV |
|---|---|---|
| Parmesan cheese, 1 oz | 331 | 33% |
| Yogurt, plain, low fat, 8 oz | 415 | 32% |
| Orange juice, calcium fortified, 1 cup | 349 | 27% |
| Tofu, firm, made with calcium sulfate, 1⁄2 cup | 253 | 19% |
| Mozzarella, part skim, 1.5 oz | 333 | 26% |
| Breakfast cereals, fortified with 10%DV, 1 serving | 130 | 10% |
According to the U. S. Food and Drug Administration, the DV for calcium is 1,300 mg for adults and children 4 years and older. Foods providing 20% or more of the DV are considered to be high sources of calcium. Foods providing lower percentages contribute to a healthy meal plan as well.
