This review examined calcium intake among adults around the world and found that many populations do not consume enough calcium to support good bone health. The authors highlight that low calcium intake is particularly common in many Asian countries, where average intakes are often well below recommended levels. Because calcium is essential for building and maintaining strong bones, inadequate intake may increase the risk of osteoporosis and fractures. The study emphasises the importance of promoting calcium rich foods and other practical ways to help people meet their daily calcium needs.

This review explores the important role of calcium in maintaining healthy bones throughout life. The authors explain that adequate calcium intake helps build and maintain bone strength, while long term low intake may contribute to bone loss and increase the risk of fractures. The paper also discusses the importance of obtaining calcium from a balanced diet, with supplements considered when dietary intake is insufficient. Overall, the review reinforces that meeting daily calcium needs is an important part of supporting lifelong bone health.

This review explores how common calcium deficiency is around the world and the impact it can have on health. The authors explain that many people do not consume enough calcium, particularly in low and middle income countries, increasing the risk of poor bone health and fractures. The paper highlights the importance of consuming enough calcium throughout life to help build and maintain strong bones. It also emphasises the need for practical strategies, such as improving access to calcium rich foods, fortified foods, and nutrition education, to help people meet their daily calcium needs.

This review explored whether eating too much salt affects bone health in postmenopausal women. The authors found that while high salt intake may increase calcium loss from the body, there is currently not enough high quality evidence to clearly determine its long term effects on bone mineral density or fracture risk. The paper highlights the need for more research to better understand this relationship. In the meantime, following general recommendations to limit excessive salt intake remains an important part of maintaining overall health.

This study explored whether salt intake was linked to bone health in postmenopausal women in southern India. The authors found that women who consumed more salt were more likely to have weaker bones, poorer bone structure, osteoporosis, and vertebral fractures. These findings suggest that excessive salt intake may be associated with poorer bone health in this population. The study adds to growing evidence that a balanced diet, including limiting excess salt, may help support healthy bones.

This review explored how protein intake and regular exercise can help slow the progression of age-related muscle loss in older adults living in the community. The authors found that combining adequate protein with strength or resistance exercise was more effective than either approach alone in helping to maintain muscle strength and physical function. The paper highlights that preserving muscle health is important for reducing the risk of falls, fractures, and loss of independence. It also reinforces the value of healthy lifestyle habits in supporting active and healthy ageing.

This consensus paper encourages a broader focus on maintaining muscle health throughout life rather than only identifying or treating sarcopenia after it develops. The authors explain that healthy muscles are essential for mobility, balance, independence, and overall wellbeing, especially as people age. The paper highlights the importance of regular physical activity, good nutrition, and early action to help preserve muscle strength and function. It also encourages healthcare professionals and the public to view muscle health as an important part of healthy ageing alongside bone health.

This review explores how lactose intolerance may affect bone health. The authors explain that people who avoid dairy because of lactose intolerance may miss out on important nutrients, particularly calcium, if these nutrients are not replaced from other foods. The paper highlights that getting enough calcium is important for maintaining strong bones and reducing the risk of fractures. It also emphasises that there are many ways to meet calcium needs, including lactose free dairy products and other calcium rich foods.

This review explores whether drinking milk can help support bone health in Asian populations, particularly those at higher risk of osteoporosis. The authors highlight that many people in Asia consume less milk than recommended, which may contribute to lower calcium intake and poorer bone health. The paper explains that milk provides important nutrients for strong bones and discusses practical options for people who cannot tolerate regular milk, such as lactose free milk and yoghurt. Overall, the review suggests that finding suitable ways to include dairy or alternative calcium rich foods in the diet may help support lifelong bone health.

This review explores ways to protect bone health in populations where calcium and vitamin D intake is often too low. The authors explain that getting enough of these nutrients is essential for building and maintaining strong bones, yet deficiencies remain common in many parts of the world. The paper highlights that healthy eating, safe sun exposure, regular physical activity, and, where needed, fortified foods or supplements can all help support bone health. It also emphasises the importance of public health efforts to improve awareness and make nutritious foods more accessible, particularly for people at greater risk of osteoporosis.

This review examined how common vitamin D deficiency is around the world and found that it remains a widespread public health concern. The authors explain that many people do not get enough vitamin D because of factors such as limited sun exposure, diet, and lifestyle. As vitamin D plays an important role in maintaining strong bones and muscles, low levels may increase the risk of poor bone health. The study highlights the importance of improving awareness and ensuring people have adequate vitamin D through safe sun exposure, diet, fortified foods, or supplements when needed.

This review examined vitamin D levels among adults living in South Asia and found that vitamin D deficiency is very common across the region. The authors explain that factors such as limited sun exposure, lifestyle, skin pigmentation, and diet may all contribute to low vitamin D levels. Because vitamin D is essential for maintaining healthy bones and muscles, addressing this deficiency is an important part of supporting lifelong bone health. The study highlights the need for greater awareness and practical strategies to help people achieve adequate vitamin D levels.

This review explores how vegetarian diets may affect bone health. The authors explain that while well planned vegetarian diets can provide many health benefits, they may also be lower in important nutrients such as calcium, vitamin D, protein, and vitamin B12 if not carefully balanced. The paper highlights that these nutrients play an important role in maintaining strong bones and reducing the risk of fractures. It also emphasises that people following vegetarian diets can support their bone health by choosing a varied, nutrient-rich diet and including fortified foods or supplements when needed.

This review examines how vegetarian diets may influence bone mineral density, a measure of bone strength. The authors explain that people following vegetarian diets may have lower bone mineral density if they do not consume enough nutrients that are important for healthy bones, such as calcium, vitamin D, and protein. However, the paper also highlights that a well planned vegetarian diet can support good bone health when these nutritional needs are met. The review emphasises the importance of choosing a balanced diet to help maintain strong bones throughout life.

This review examined how vegan and vegetarian diets may affect bone mineral density and fracture risk. The authors found that people following plant based diets, particularly vegan diets, may have lower bone mineral density and a higher risk of fractures if they do not get enough nutrients that support bone health. The paper highlights the importance of consuming adequate calcium, vitamin D, protein, and other key nutrients when following a plant based diet. It also emphasises that well planned vegetarian and vegan diets can support healthy bones when nutritional needs are carefully met.
