11 Foods for Healthy Bones

Build a strong structure
When it comes to building strong bones, there are two key nutrients: calcium and vitamin D. Calcium supports your bones and teeth structure, while vitamin D improves calcium absorption and bone growth.

These nutrients are important early in life, but they may also help as you age. If you develop osteoporosis, a disease characterized by brittle and breaking bones, getting plenty of calcium and vitamin D may slow the disease and prevent fractures.

Adults up to age 50 should get 1,000 milligrams of calcium and 200 international units (IUs) of vitamin D a day. Adults over 50 should get 1,200 milligrams of calcium and 400 to 600 IU of vitamin D. Get these nutrients by trying these 11 foods for healthy bones.

Yogurt
Most people get their vitamin D through exposure to sunlight, but certain foods, like yogurt, are fortified with vitamin D.

One cup of yogurt can be a creamy way to get your daily calcium. Stonyfield Farms makes a fat-free plain yogurt that contains 30% of your calcium and 20% of your vitamin D for the day. And though we love the protein-packed Greek yogurts, these varieties tend to contain less calcium and little, if any, vitamin D

Milk
There’s a reason milk is the poster child for calcium. Eight ounces of fat-free milk will cost you 90 calories, but provide you with 30% of your daily dose of calcium. Choose a brand fortified with vitamin D to get double the benefits.

Can’t get three glasses a day? Try blending milk into a smoothie or sauce.

Cheese
Just because cheese is full of calcium doesn’t mean you need to eat it in excess (packing on the pounds won’t help your joints!). Just 1.5 ounces (think a set of dice) of cheddar cheese contains more than 30% of your daily value of calcium, so enjoy in moderation.

Most cheeses contain a small amount of vitamin D, but not enough to put a large dent in your daily needs.

Sardines
These tiny fish, often found in cans, have surprisingly high levels of both vitamin D and calcium. Though they may look a bit odd, they have a savory taste that can be delicious in pastas and salads.

Eggs
Though eggs only contain 6% of your daily vitamin D, they’re a quick and easy way to get it. Just don’t opt for egg whites—they may cut calories, but the vitamin D is in the yolk.

Salmon
Salmon is known for having plenty of heart-healthy omega-3 fatty acids, but a 3-ounce piece of sockeye salmon contains more than 100% of your vitamin D. So eat up for your heart and your bones.

Spinach
Don’t eat dairy products? Spinach will be your new favorite way to get calcium. One cup of cooked spinach contains almost 25% of your daily calcium, plus fiber, iron, and vitamin A.

Fortified cereal
Certain cereals—like Kashi U Black Currants and Walnuts, Total Whole Grain, and Wheaties—contain up to 25% of your daily vitamin D. When you don’t have time to cook salmon or get out in the sun, cereals can be a tasty way to get your vitamin D.

Tuna
Tuna, another fatty fish, is a good source of vitamin D. Three ounces of canned tuna contains 154 IU, or about 39% of your daily dose of the sunshine vitamin. Try these low-cal Tuna-Melt Tacos as a way to sneak in vitamin D and calcium.

Collard greens
Like spinach, this leafy green often enjoyed south of the Mason-Dixon line is full of calcium. One cup of cooked collards contains more than 25% of your daily calcium. Plus you can easily sneak it into your favorite foods, like this über-healthy frittata.

Orange juice
A glass of fresh-squeezed OJ doesn’t have calcium or vitamin D, but it’s often fortified to contain these nutrients. Try Tropicana’s Calcium + Vitamin D to get a boost of these essentials.

Also, studies have shown that the ascorbic acid in OJ may help with calcium absorption, so you may be more likely to get the benefits of this fortified drink.

Meat and cheese may be as bad as smoking

Researchers have found that eating a diet rich in animal proteins during middle age makes you four times more likely to die of cancer than someone with a low-protein diet — a mortality risk factor comparable to smoking.

“There’s a misconception that because we all eat, understanding nutrition is simple. But the question is not whether a certain diet allows you to do well for three days, but can it help you survive to be 100?” said corresponding author Valter Longo, Edna M. Jones Professor of Biogerontology at the USC Davis School of Gerontology and director of the USC Longevity Institute.

Not only is excessive protein consumption linked to a dramatic rise in cancer mortality, but middle-aged people who eat lots of proteins from animal sources — including meat, milk and cheese — are also more susceptible to early death in general, revealed the study published today in Cell Metabolism. Protein-lovers were 74 percent more likely to die of any cause within the study period than their more low-protein counterparts. They were also several times more likely to die of diabetes.

But how much protein one should eat has long been a controversial topic — muddled by the popularity of protein-heavy diets such as Paleo and Atkins. Before this study, researchers had never shown a definitive correlation between high-protein consumption and mortality risk.

Rather than look at adulthood as one monolithic phase of life, as other researchers have done, the latest study considers how biology changes as we age and how decisions in middle life may play out across the human life span.

In other words, what’s good for you at one age may be damaging at another. Protein controls the growth hormone IGF-I, which helps our bodies grow but has been linked to cancer susceptibility. Levels of IGF-I drop off dramatically after age 65, leading to potential frailty and muscle loss. The study shows that while high-protein intake during middle age is very harmful, it is protective for older adults: those over 65 who ate a moderate- or high-protein diet were less susceptible to disease.

The latest paper draws from Longo’s past research on IGF-I, including on an Ecuadorian cohort that seemed to have little cancer or diabetes susceptibility because of a genetic mutation that lowered levels of IGF-I; the members of the cohort were all less than 5-feet tall.

“The research shows that a low-protein diet in middle age is useful for preventing cancer and overall mortality, through a process that involves regulating IGF-I and possibly insulin levels,” said co-author Eileen Crimmins, holder of the AARP Chair in Gerontology at USC. “However, we also propose that at older ages, it may be important to avoid a low-protein diet to allow the maintenance of healthy weight and protection from frailty.”

Crucially, the researchers found that plant-based proteins, such as those from beans, did not seem to have the same mortality effects as animal proteins. Rates of cancer and death also did not seem to be affected by controlling for carbohydrate or fat consumption, suggesting that animal protein is the main culprit.

“The majority of Americans are eating about twice as much proteins as they should, and it seems that the best change would be to lower the daily intake of all proteins but especially animal-derived proteins,” Longo said. “But don’t get extreme in cutting out protein; you can go from protected to malnourished very quickly.”
