The Role of Diet in Managing Bone Health and Preventing Falls
As we age, maintaining strong bones and preventing falls becomes increasingly important. Falls are a major issue in Australia and New Zealand, as over 30% of adults aged 65 and above experience at least one fall a year. This results in injuries to the hip, lower limb, head, and neck, costing millions in treatments.
Bone health is essential not only for mobility and independence but also for overall well-being. A significant factor in this equation is diet. The nutrients we consume play a pivotal role in building and maintaining bone density, as well as supporting muscle function to reduce the risk of falls.
This article explores the connection between diet, bone health, and fall prevention, offering insights into the best dietary practices for optimal outcomes.

Understanding Bone Health
Bones are dynamic tissues that constantly undergo a process of breakdown and regeneration known as bone remodelling. During this process, osteoclasts break down old bone tissue, while osteoblasts create new bone tissue.
For optimal bone health, these processes must remain balanced. However, factors such as aging, hormonal changes, and poor nutrition can disrupt this balance, leading to weakened bones or conditions like osteoporosis.
Osteoporosis, characterised by low bone density and structural deterioration, increases the risk of fractures, particularly in older adults. Hip fractures, in particular, can lead to significant disability and even mortality. Therefore, addressing bone health through dietary measures is a proactive way to prevent these outcomes.
Key Nutrients for Bone Health
Several nutrients are crucial for maintaining strong bones. These include:
Calcium
Calcium is the cornerstone of bone health. Approximately 99% of the body’s calcium is stored in bones and teeth. This mineral provides structural support and contributes to the strength of the skeletal system.
Dietary sources of calcium include dairy products like milk, cheese, and yogurt, as well as plant-based options such as fortified almond milk, tofu, kale, and broccoli. Additionally, small fish like sardines, eaten with their bones, are excellent sources of calcium.
Vitamin D
Vitamin D is essential for calcium absorption. Without adequate vitamin D, even a calcium-rich diet may not suffice for bone health. Sun exposure is a primary source of vitamin D, but dietary sources like fatty fish (e.g., salmon and mackerel), egg yolks, and fortified foods also contribute. In regions with limited sunlight, supplementation might be necessary to meet daily requirements.
Magnesium
Magnesium plays a role in converting vitamin D into its active form, which enhances calcium absorption. Foods rich in magnesium include nuts, seeds, whole grains, and leafy green vegetables. Magnesium also supports muscle function, which is vital for balance and fall prevention.
Phosphorus
Phosphorus works in tandem with calcium to build strong bones. It is found in protein-rich foods such as meat, poultry, fish, eggs, and dairy products. However, excessive phosphorus intake from processed foods or soft drinks can harm bone health by disrupting the calcium-phosphorus balance.
Vitamin K
Vitamin K supports bone mineralisation and regulates calcium in the body. Leafy greens like spinach, kale, and Swiss chard are excellent sources of this vitamin. Fermented foods like natto (fermented soybeans) are also particularly high in vitamin K2, a form beneficial for bone health.
Protein
Adequate protein intake is necessary for bone structure and repair. However, excessive protein consumption, especially without adequate calcium, may lead to calcium loss. Balance is key. Incorporating both animal and plant-based proteins can provide a wide array of nutrients that support overall health.
Omega-3 Fatty Acids
Omega-3 fatty acids, found in fatty fish, flaxseeds, chia seeds, and walnuts, have anti-inflammatory properties that may protect bone health. Chronic inflammation can negatively impact bone density, making omega-3s an important part of a bone-friendly diet.

The Role of Diet in Fall Prevention
Beyond bone health, diet plays a critical role in preventing falls. Falls often result from a combination of factors, including muscle weakness, poor balance, and impaired vision. Proper nutrition can address these issues in several ways:
Muscle Strength and Function
Protein-rich foods are vital for maintaining muscle mass and strength, particularly in older adults. A diet that includes lean meats, legumes, nuts, and seeds supports muscle repair and function. Additionally, incorporating foods rich in branched-chain amino acids (BCAAs), such as eggs and dairy, can enhance muscle protein synthesis.
Energy Levels
A well-balanced diet ensures sufficient energy levels to stay active and maintain balance. Whole grains, fruits, and vegetables provide sustained energy through complex carbohydrates and fibre. Avoiding excessive sugar and refined carbs helps prevent energy crashes that could lead to fatigue.
Hydration
Dehydration can lead to dizziness and fatigue, increasing the risk of falls. Drinking adequate water and consuming water-rich foods like cucumbers, watermelon, and oranges helps maintain hydration. Herbal teas and clear broths can also contribute to fluid intake.
Vision Support
Nutrients like vitamin A, lutein, and zeaxanthin support eye health, reducing vision-related fall risks. Foods such as carrots, sweet potatoes, and dark leafy greens are excellent sources. Omega-3 fatty acids also contribute to retinal health, further protecting vision.
Dietary Strategies for Optimal Bone Health and Fall Prevention
To harness the power of diet in managing bone health and preventing falls, consider these strategies:
Adopt a Balanced Diet
A balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats ensures a comprehensive intake of essential nutrients. The Mediterranean diet, with its emphasis on plant-based foods, healthy fats, and moderate protein, is particularly beneficial for bone health.
Incorporate Bone-Friendly Foods
Regularly include calcium-rich and vitamin D-rich foods in your meals. For instance, start your day with fortified cereal and milk, add leafy greens to your lunch, and include a serving of grilled salmon or tofu in your dinner. Snacks like yogurt with almonds or a smoothie with fortified plant milk can also boost calcium intake.
Monitor Sodium Intake
Excess sodium can lead to calcium loss through urine. Limit processed and salty foods to protect bone health. Season foods with herbs and spices instead of salt to enhance flavour without compromising nutrition.
Stay Active with Proper Nutrition
Combine a nutritious diet with weight-bearing exercises like walking, jogging, or resistance training to enhance bone density and muscle strength. Pairing physical activity with post-workout snacks that include protein and carbohydrates can support recovery and muscle growth.
Supplement Wisely
If dietary intake is insufficient, supplements may be necessary. Consult a healthcare professional before starting calcium, vitamin D, or other supplements. Look for supplements that combine calcium with vitamin D and magnesium for better absorption and efficacy.
Limit Bone-Depleting Substances
Reduce consumption of alcohol, caffeine, and tobacco, as these can negatively impact bone health. Instead, focus on hydrating beverages like herbal teas or infused water. Also, some drugs like heparin, warfarin, cyclosporine, glucocorticoids, medroxyprogesterone acetate, and cancer drugs can lead to bone loss.

Special Considerations for Different Life Stages
Bone health and fall prevention are concerns that span all ages. Here are some specific considerations:
Children and Adolescents
During growth spurts, adequate calcium and vitamin D intake is critical for achieving peak bone mass. Encourage dairy consumption, outdoor play for sunlight exposure, and the inclusion of fortified foods to support bone development.
Adults
Bone density begins to decline in adulthood. Maintain a nutrient-rich diet and stay active to slow this process. Including anti-inflammatory foods like berries, turmeric, and green tea can help counteract age-related bone loss.
Postmenopausal Women
Hormonal changes after menopause accelerate bone loss. Foods rich in calcium, vitamin D, and phytoestrogens (e.g., soy products, flaxseeds, and chickpeas) can help mitigate this. Weight-bearing exercises are particularly important for this group.
Older Adults
Older adults face an increased risk of falls and fractures. Focus on nutrient-dense foods that are easy to chew and digest, and consider fortified products if necessary. Protein shakes and fortified plant-based milks can be convenient options for those with reduced appetites.
The Bigger Picture: Lifestyle and Bone Health
While diet is a cornerstone of bone health, it’s important to consider other lifestyle factors:
Physical Activity
Regular exercise, particularly weight-bearing and strength-training activities, stimulates bone formation and improves balance and coordination. Yoga and tai chi can also enhance flexibility and reduce fall risks.
Sunlight Exposure
Safe sunlight exposure supports natural vitamin D production, which is vital for calcium absorption. Aim for 10-30 minutes of sunlight on the skin several times a week, depending on skin type and location.
Fall-Proofing Your Environment
Minimise fall risks by keeping living spaces clutter-free, using non-slip mats, and ensuring proper lighting. Installing handrails and grab bars in key areas can provide additional support.
Regular Check-Ups
Bone density tests and regular health screenings can identify risks early and guide dietary and lifestyle adjustments. Addressing vision or hearing impairments promptly can also reduce fall risks.
