Dairy-Free Bone-Strengthening Foods That Might Surprise You

Luckily, there are lots of dairy-free foods that contain the essential nutrients needed to build and maintain strong bones, including calcium, vitamin D, vitamin C, protein, magnesium, phosphorus, manganese, potassium, omega-3 fatty acids, vitamin K, and the B vitamins.
“Calcium gets all the attention, but bone health is about so much more than calcium,” says Danielle Sanders, RD, a lecturer at Yale School of Medicine Department of Internal Medicine Section of Digestive Diseases in New Haven, Connecticut. “I think oftentimes people forget that bone is a living tissue. It’s constantly being broken down and rebuilt, so it requires a constant supply of nutrients.”

Essential Nutrients for Bone Health
In addition to calcium, it’s best to consume a combination of other nutrients for optimal bone-building benefits, says Gretchen Zimmerman, RD, CDCES, a New York City–based spokesperson for the Academy of Nutrition and Dietetics. These include:
- Vitamin C, which plays a key role in the biosynthesis of collagen, an essential component of bone.
- Vitamin D to help the body absorb calcium and prevent osteoporosis.
- Protein, which helps to keep your bones dense and strong and may lower osteoporosis risk, Zimmerman says.
- Magnesium to activate the enzymes that build new bone and help convert vitamin D into its active form, Zimmerman says, which helps your body absorb calcium.
- Potassium to maintain the pH balance in the body, which may prevent calcium from leaching out of your bones and promote higher bone mineral density.
- Manganese, which plays a critical role in bone regeneration, density, and overall skeletal strength, research suggests.
- Omega-3s, which may reduce the risk of osteoporosis by promoting bone formation and preventing bone decay, Zimmerman says.
Fruits and Vegetables
- Cooked collard greens
- Cooked spinach (Zimmerman recommends cooking or steaming spinach to remove the oxalic acid, which is a naturally occurring compound in many greens that can inhibit calcium absorption.)
- Raw turnip greens
- Bok choy
Cruciferous vegetables are rich sources of vitamin C and generally low in oxalic acid, which means they can help your body absorb calcium, Zimmerman says. Good choices include:
- Broccoli
- Brussels sprouts
- Kale
Although not a cruciferous vegetable, red bell peppers are an excellent source of vitamin C.
- Guava
- Oranges
- Grapefruit
- Strawberries
- Cantaloupe
- Kiwi
- Mango
- Papaya
- Pineapple
Meat, Seafood, and Plant Proteins
Since protein and vitamin D are both important for bone development and retention, foods that contain both do double duty. Firm and extra-firm tofu are great sources of calcium, protein, and phosphorus, and contain vitamin D when fortified, Zimmerman says.
- Shellfish
- Mackerel
- Trout
- Tuna
- Quinoa
- Eggs
- Poultry, beef, lamb, and pork
Nuts, Seeds, and Legumes
Sanders recommends the following seed options for good sources of omega-3s, protein, potassium, magnesium, calcium, and B vitamins:
- Flaxseeds
- Chia seeds
- Sunflower seeds
- Sesame seeds
- Sprouted seeds, such as pea or radish shoots, or broccoli, radish, sunflower, and arugula sprouts
- Chickpeas
- Kidney beans
- White beans
- Lentils
- Soybeans
