Genetics dictate how strong someone's skeleton is, but there is much that can be done to keep bones healthy, which is particularly important as people get older.

Diet-wise, calcium and vitamin D are essential. Calcium can be obtained in the diet, for example from dairy products, dried fruit and leafy green vegetables, but the majority of vitamin D is made in the skin as a response to sunlight, so people who don't get outdoors very much are at risk of having low levels. If you think someone might fall into this category, you could speak to them about vitamin D supplements.

Exercise is also crucial for healthy bones, particularly exercises that involve resistance or weight bearing. Older people are likely to shy away from very high impact exercise, but walking, dancing, swimming, gardening, yoga and keep fit classes can all help. Anyone who is concerned about becoming more active should speak to the pharmacist or a GP. Other factors that influence how strong someone's bones are include whether they smoke or drink alcohol, as both can have a negative effect.

Dancing can be a great way for older people to stay active
