Diet and nutrition are important factors in maintaining bone health. Bones undergo a continuous process of remodelling, where they break down and rebuild themselves. This process is influenced by various factors, including age, sex, and diet. For example, after menopause, women tend to lose bone density faster than their bodies can replace it, increasing their risk of osteoporosis. Additionally, rapid weight loss is often associated with a decrease in bone density, whereas slower weight loss coupled with exercise training may help maintain bone health. Certain dietary patterns, such as a diet rich in fruits, vegetables, whole grains, and low-fat dairy products, have been shown to positively impact bone health, while diets high in soft drinks, fried foods, and processed products may negatively affect bone mass.

High-protein diets and bone mass
Diet and exercise play a crucial role in maintaining and improving bone health. While bone continuously breaks down and rebuilds itself, our bone mass peaks when we are around 30 years old and remains steady for the next two decades. After menopause, women tend to lose bone density faster than their bodies can replace it, and aging can cause the body to leach calcium from bones. Therefore, it is essential to maintain a diet rich in calcium and vitamin D, which helps the body absorb calcium. Dairy products, dark leafy greens, and fortified breakfast cereals and fruit juices are excellent sources of calcium.
Protein is also essential for bone health, as it is closely associated with bone mineral density (BMD), a critical factor in bone strength. A positive correlation exists between protein intake and bone mass gain, especially in children and adolescents, where protein plays a pivotal role in bone mass acquisition. Adequate protein intake is necessary for optimal bone mass gain during growth and preserving bone and muscle mass during aging. Insufficient protein intake can lower the production and action of Insulin-like Growth Factor (IGF-1), which enhances bone formation and stimulates the intestinal absorption of bone minerals like calcium and phosphate.
High-protein diets are beneficial for bone health, but they must be accompanied by adequate calcium intake. Research suggests that a diet with high levels of protein significantly benefits muscle mass and bone health. Amino acids, derived from dietary protein, preserve bone, reduce the rate of bone loss, and improve overall bone health. Additionally, adequate protein intake is particularly crucial for seniors with osteoporosis, as it helps prevent muscle weakness, sarcopenia, and frailty, reducing the risk of falling.
While moderate weight loss does not seem to negatively impact bone health, rapid or large weight loss is often associated with a decrease in bone density. Exercise, especially high-impact training, can help mitigate bone density loss during weight loss. Resistance training and high-impact exercises like jumping can effectively maintain or even increase bone density. Combining resistance and high-impact jump training has been shown to reduce bone loss in older adults.

Calcium-rich foods
Calcium is essential for maintaining healthy bones. While bone continuously breaks down and rebuilds itself in a process called remodeling, calcium is released into the bloodstream, and we replenish the supply with the calcium we consume. Our bone mass typically reaches its peak when we are around 30 years old and remains steady for the next two decades. However, after menopause, bone loss accelerates, and aging can prompt the body to leach calcium from bones.
- Dairy products: Milk, yogurt, and cheese are well-known sources of calcium.
- Dark leafy greens: Collards, kale, Swiss chard, and broccoli contain calcium and other essential nutrients.
- Fortified foods: Breakfast cereals and fruit juices are often fortified with calcium.
- Seafood: Salmon, sardines, shrimp, crab, and oysters are good sources of calcium.
- Dried fruits: Prunes and dried figs can boost bone health and reduce the risk of bone breakdown.
- Plant-based sources: Tofu, almonds, and almond butter provide calcium for those following a plant-based diet.
- Canned fish: Canned salmon is another option to increase your calcium intake.
- Legumes: White beans and other legumes can contribute to your daily calcium needs.
In addition to calcium-rich foods, vitamin D is crucial for helping your body absorb calcium effectively. Vitamin D can be obtained through exposure to sunlight, and supplements can also help make up for any shortfall in your diet.

Resistance training
The magnitude of mechanical load is important for bone formation, and RE elicits a magnitude of strain that exceeds the threshold required for increased bone modeling. RE has been frequently prescribed because it has been consistently shown to be safe and effective for improving muscle mass, size, and strength in middle-aged and older adults, including the frail elderly and even those with a history of fracture.
Research indicates that resistance training may have a more profound site-specific effect on bone density than aerobic exercise. Over the past 10 years, nearly two dozen cross-sectional and longitudinal studies have shown a direct and positive relationship between the effects of resistance training and bone density. However, a handful of other studies have reported little or no effect on bone density. These conflicting results may be due to variations in study design, exercise protocol intensity and duration, and bone density measurement techniques.
High-intensity resistance training has the added benefit of influencing multiple risk factors for osteoporosis, including improved strength and balance and increased muscle mass. For example, resistance training over 2 years increases bone mass in calcium-replete postmenopausal women. Furthermore, resistance training is the best strategy for maintaining lean tissue during weight loss, and it can be combined with high-impact jump training to further reduce the loss of bone mineral density.

High-impact exercises
Exercise is one of the pillars of bone care and fall prevention. It is important to note that muscle-strengthening exercises help maintain bone strength, but to improve bone strength, it is necessary to increase the intensity of the workout over time. This is why progressive muscle resistance training is the best type of muscle-strengthening exercise for your bones.

Obesity and bone strength
Obesity is a concern for bone health, especially as people age. While it is traditionally believed that obesity is beneficial to bone health due to the positive effect of body weight on bone formation, recent studies have challenged this notion. Obese individuals have a higher risk of fragility fractures, where bones break from a low-impact fall, a sudden twist, or even a cough or sneeze. This is because obesity may affect bone quality and remodeling, and it is associated with other conditions such as type 2 diabetes and chronic kidney disease, which can further compromise bone health.
The relationship between obesity and bone health is complex and influenced by various factors. One factor is the increased secretion of certain pancreatic hormones, such as insulin, amylin, and preptin, which can affect bone health. Additionally, obesity is associated with chronic inflammation, which may promote osteoclast activity and bone resorption through the modification of specific pathways. The excessive secretion of leptin and/or decreased production of adiponectin by adipocytes in obesity can also impact bone formation or resorption. Furthermore, a high-fat diet may interfere with intestinal calcium absorption, reducing the availability of calcium for bone formation.
Visceral adipose tissue (VAT) has been associated with reduced bone mass in middle-aged and older adults, while subcutaneous adipose tissue (SAT) has been found to protect bone health. However, after correcting for body weight, these effects become less apparent. Obese individuals might have differences in their bone quality, such as alterations in bone-regulating hormones, inflammation, oxidative stress, and the endocannabinoid system, which can affect bone cell metabolism.
To maintain bone health, it is important to focus on diet and exercise. A varied diet that includes calcium-rich foods such as dairy products, dark leafy greens, and fortified breakfast cereals can help maintain bone strength. Vitamin D is also crucial as it helps the body absorb calcium. Additionally, resistance training and high-impact exercises can help maintain or increase bone density, even during weight loss. However, further research is needed to determine the optimal exercise routines for maintaining bone mineral density (BMD) during weight loss.

Frequently asked questions
Diet can influence bone mass. A diet that emphasizes the intake of fruits, vegetables, whole grains, poultry, fish, nuts, legumes, and low-fat dairy products has a beneficial impact on bone health. In contrast, a “Western” dietary pattern featuring unhealthy foods like soft drinks, fried foods, sweets, and refined grains is associated with poorer bone health.
Foods that are high in calcium, such as dairy products, dark leafy greens (e.g., collards, kale, Swiss chard, and broccoli), and fortified breakfast cereals and fruit juices, are known to improve bone health. Prunes, dried figs, canned salmon, plant milks, tofu, almonds, and white beans are also considered bone-friendly foods.
Exercise training, particularly high-impact loading and resistance training, can help maintain or even increase bone mass. For example, gymnasts tend to have higher bone mineral density (BMD) than runners or swimmers due to the high impact nature of their sport.
Rapid or large weight loss is often associated with a decrease in bone density. However, moderate weight loss, especially when accompanied by exercise, does not seem to negatively impact bone health. In fact, a higher-protein diet that emphasizes lean meats and low-fat dairy foods can lead to weight loss without bone loss.
