Bone health depends on a combination of diet, movement, hormones, and daily habits working together, not on any single nutrient or workout. When Val Stones, a beloved contestant from "The Great British Baking Show," broke her wrist at age 56 after a simple misstep, she discovered she had osteoporosis, the "silent disease" that weakens bones without warning .

Osteoporosis affects about 10 million people in the United States and over 3 million people in the United Kingdom, with women making up the majority of cases . The condition often develops quietly from osteopenia, a state of lower-than-normal bone density that, if left unchecked, can progress to significant bone loss and increased fracture risk.

Why Does Bone Loss Happen, and Can You Reverse It?

Bones constantly remodel throughout life, with old bone breaking down and new bone forming in its place. With age and during transitions like menopause, the balance often tips toward bone loss. However, research shows this isn't inevitable.

"Increasing bone density means improving both strength of the bone and the amount of mineral packed within it. This happens only when the body builds new bone faster than it breaks old bone down," explained Dr. Connie Oh, a sports medicine physician at Hoag Orthopedic Institute in Irvine, California.

A landmark 2021 study following over 7,000 older adults in care homes over two years found that those who increased their intake of calcium and protein-rich foods had 33% fewer fractures overall, nearly half as many hip fractures, and an 11% lower risk of falls . In a 2023 study of postmenopausal women with osteoporosis, those who followed a structured lifestyle program alongside usual care saw greater improvements in bone density after six months than those receiving standard care alone .

What Foods Actually Build Stronger Bones?

Stones discovered that her diet was low in healthy fats and calcium, both essential for building bone. After her diagnosis, she increased her intake of calcium-rich foods and developed recipes, including a cake made with soy milk, dried fruits, and calcium-rich seeds. The key insight: a person's overall diet matters more than any single nutrient.

Calcium and vitamin D form the foundation of bone health. Calcium helps build and maintain strong bones, while vitamin D allows the body to absorb that calcium effectively. Without enough of either, bones gradually weaken over time.

"Protein is essential because it helps build muscle. If you're building muscle strength, you're also building bone strength," noted Lindsay Malone, an instructor and functional medicine dietitian in Case Western Reserve University School of Medicine's department of nutrition.

Higher protein intake is linked to greater bone density, but it only helps up to a certain point. In a 2025 study, women saw gains when eating up to about 60 grams of protein a day; beyond that, eating more didn't seem to provide extra bone strength .

How to Build Bone Density Through Nutrition

• Vitamin D Sources: Egg yolks, fortified foods, fatty fish like salmon and sardines, certain cheeses such as Parmesan-Reggiano, low-fat ricotta and part-skim mozzarella, and liver. If you're not eating these foods regularly, a vitamin D supplement is appropriate.
• Calcium Sources: For those who don't consume dairy, choose fortified plant milks, calcium-fortified tofu, canned fish with bones, beans, nuts, seeds, whole grains, and legumes for extra mineral support.
• Additional Minerals: Magnesium, vitamin K, potassium, phosphorus, and trace minerals also help maintain healthy bones and should be included in a varied, whole-food diet.
• Fat Absorption: Vitamin D is fat-soluble, meaning it's best absorbed when eaten with healthy fats, so pair these foods with olive oil or other healthy fat sources.

Many people can meet their nutrient needs through food by following a varied, whole-food diet. Experts recommend anchoring meals with protein, eating about 2 cups of vegetables each day, including leafy greens several times a week, and regularly choosing fortified or calcium-rich foods .

Does Exercise Really Strengthen Bones?

It's not just diet. Getting moving is equally important for protecting and building bone. During exercise, muscles release the hormone irisin, a molecule that directly stimulates bone-building cells and helps increase bone density and strength.

"The best ways to build bone density are resistance exercises, like lifting weights and exercises that make your bones take impact, such as jumping or running," said Ashley Katzenback, a doctor of physical therapy at Cape Concierge Physical Therapy in Massachusetts.

Studies show that when done carefully and under supervision, resistance training and high-impact exercises can help improve or maintain bone density in postmenopausal women, especially in the spine and hip, which are common sites for fractures . The key is using a weight that feels challenging enough to make your muscles work. Katzenback recommends four sets of five repetitions with heavy weights to stimulate bone growth, and notes that it's best to combine resistance and impact exercises, though resistance training is the most effective.

Stones, now almost 76 years old, does balance exercises every day to help prevent falls, along with stretching, light weights, and push-ups. She aims for about 7,000 steps per day and finds opportunities to move throughout the day, such as walking while waiting for a kettle to boil or a cake to mix .

What Changed for Val Stones After Her Diagnosis?

Twenty years after her osteoporosis diagnosis, Stones manages the condition through regular exercise and good nutrition. She reflected on what she would tell her younger self: "If I could, I would tell my younger self to eat not only the greens and oranges but the whites and creams too" . This simple wisdom captures the importance of a balanced diet that includes calcium-rich foods beyond just vegetables.

She

Stones has become an advocate for bone health, developing bone-friendly recipes inspired by her love of baking and sharing them with the Royal Osteoporosis Society in the United Kingdom. Her story demonstrates that while osteoporosis is a serious condition, it's manageable through lifestyle changes that can be sustained over decades.

The takeaway is clear: supporting bone health earlier in life through a combination of nutrient-dense foods, regular exercise, and everyday movement builds a stronger foundation for later years. Before beginning any new exercise program, consult your doctor and stop immediately if you experience pain .
