Strong bones matter at every age, but they become especially important as we grow older. Over time, bones naturally lose some of their density, increasing the risk of osteoporosis and fractures. Calcium plays an essential role in maintaining bone strength, but the body cannot produce it on its own. It must come from food or, when medically appropriate, supplements.
Fortunately, calcium is available in more foods than many people realize. From familiar dairy products to leafy greens and fortified foods, there are plenty of ways to support aging bones while enjoying a varied and satisfying diet.
Calcium needs vary by age and sex. According to the National Institutes of Health Office of Dietary Supplements, the general daily recommendations are:
These amounts include calcium from both foods and supplements. Individual needs may vary based on health conditions, medications and osteoporosis risk, so a healthcare provider or registered dietitian can offer personalized guidance.
Milk, yogurt and cheese are among the most familiar sources of calcium. They also provide protein and other nutrients that support healthy aging.
A cup of milk typically provides about 300 milligrams of calcium, while the amount in yogurt and cheese varies by type and serving size. Greek yogurt, cottage cheese and lower-fat cheeses can make convenient additions to meals and snacks.
Easy ways to add dairy include:
For those who have difficulty digesting lactose, lactose-free milk and yogurt can provide similar nutritional benefits without the discomfort.
People who avoid dairy can still find excellent calcium sources. Many soy, almond and oat beverages are fortified with calcium and vitamin D.
The amount varies by brand, so check the Nutrition Facts label. Fortified soy beverages often offer the nutritional profile most comparable to dairy milk because they also contain protein.
Calcium may settle at the bottom of the container, so shake the beverage well before pouring it. Plant-based beverages can be used in cereal, smoothies, soups and recipes just as dairy milk would be.
Canned salmon and sardines are rich in calcium when the soft, edible bones are included. The canning process makes the bones tender enough to eat, and they can usually be mashed easily into the fish.
These foods also provide protein and omega-3 fatty acids. Try adding canned salmon to a salad, mixing it into patties or enjoying sardines on whole-grain toast.
Be sure to choose products labeled “with bones” if calcium is your primary goal. People limiting sodium should also compare labels or look for lower-sodium options.
Tofu can be a valuable source of calcium, especially for those following a vegetarian or dairy-free diet. However, calcium content varies based on how the tofu is made.
Look for calcium sulfate in the ingredient list and check the Nutrition Facts label to determine how much calcium is included in each serving. Tofu can be added to stir-fries, soups, salads and casseroles or blended into smoothies and sauces.
Some vegetables provide calcium along with fiber, vitamins and antioxidants. Good choices include:
The calcium in certain leafy greens is absorbed well by the body. Spinach contains calcium, but it also contains compounds called oxalates that make much of that calcium harder to absorb. Spinach remains nutritious, but it should not be someone’s only calcium-rich vegetable.
Try adding greens to soups, omelets and casseroles or serving them as a flavorful side dish.
Calcium is added to many cereals, breads, juices and other packaged foods. Fortified products can help fill nutritional gaps, particularly for people with smaller appetites or dietary restrictions.
Because calcium amounts vary widely, read the label carefully. The Food and Drug Administration considers a food providing 20% or more of the Daily Value per serving to be high in that nutrient. Remember that fortified foods may also contain added sugar or sodium, so consider the complete nutrition label rather than calcium alone.
Beans, almonds, sesame seeds and chia seeds can contribute smaller amounts of calcium throughout the day. They also offer protein, fiber and healthy fats.
Consider adding:
These foods may not provide an entire day’s calcium on their own, but they can make an important contribution as part of a balanced diet.
Calcium does not work alone. Vitamin D helps the body absorb calcium, while protein supports the muscles that protect bones and help maintain balance.
The National Institute on Aging recommends getting enough calcium, vitamin D and protein while remaining physically active. Vitamin D is available in certain fish, egg yolks and fortified foods, but some older adults may have difficulty getting enough through food alone.
Weight-bearing and resistance activities also support bone health. Walking, dancing and appropriately designed strength exercises can help maintain bones, muscles and balance.
Food is generally the preferred source of calcium because it provides additional nutrients and allows calcium to be consumed throughout the day. However, some people may need a supplement if they cannot meet their needs through food.
More is not always better. Excess calcium may cause side effects or interact with certain medications. Supplements can also affect how the body absorbs thyroid medication, some antibiotics and other prescriptions.
Before beginning calcium or vitamin D supplements, talk with a physician, pharmacist or registered dietitian. They can consider the calcium already present in your diet and recommend an appropriate amount and schedule.
At Arbor Oaks at Crestview, wellness includes making everyday choices that support the body, mind and spirit. Enjoyable meals, regular activity and opportunities for social connection all contribute to a healthier and more fulfilling retirement.
Strong bones are built through consistent habits rather than a single food or supplement. By choosing a variety of calcium-rich foods, getting adequate vitamin D and protein and remaining active, older adults can take meaningful steps toward protecting their mobility and independence.
Healthy aging can be both nutritious and delicious—and every meal offers another opportunity to care for the life you want to keep living.
