1. How can you look after your bones?
If you're worried about your risk of osteoporosis, certain lifestyle changes can help to look after your bones. For example:
- Diet, calcium and vitamin D
- Physical activity
If you have already lost some bone density, or have osteoporosis, lifestyle changes cannot cure or reverse the problem but may stop it getting worse. Find out more about osteoporosis and breast cancer treatment.
2. Diet, calcium and vitamin D
Diet and breast cancer: Why is a balanced diet important?
A varied and balanced diet will give you the nutrients that are important for strong, healthy bones.
Calcium is a vital mineral for teeth and bones because it gives them strength and hardness. Our bodies contain about 1kg of calcium and 99% of it is found in our bones.
Our main dietary source of calcium is dairy produce. Most people get enough calcium through a healthy diet that includes dairy products. Three portions of dairy a day will give you the recommended amount of calcium if you do not already have osteoporosis.
If you do not eat or drink any dairy products, it’s important to ensure you still get enough calcium in your diet from other non-dairy sources. Milk alternatives such as soya, rice and almond milk do not naturally contain as much calcium as cow’s milk. Choosing dairy alternatives with added calcium can be helpful.
Good sources of calcium include:
- Milk and dairy products (including low-fat varieties) such as yoghurt, fromage frais and cheese
- Calcium-fortified breakfast cereals
- Dried fruit such as apricots and figs
- Fish with edible bones such as anchovies, sardines, pilchards and whitebait
- Green leafy vegetables like broccoli, watercress and kale
- Pulses, beans and seeds such as kidney beans, green beans, baked beans and tofu
- Nuts and seeds such as almonds, brazil nuts, hazelnuts and sesame seeds
The calcium content of drinking water varies greatly across the UK. Some bottled mineral waters are calcium enriched. You may need to take a calcium supplement if you do not get enough calcium from your diet alone.
How much calcium do I need?
Adults need around 700mg of calcium a day. Someone with or at risk of osteoporosis may be advised to have around 1,000–1,200mg a day. See below for a guide to the calcium values of some common foods (all figures are approximate).
Calcium rich food per average portion:
- 40g of Edam/Gouda cheese has a calcium value of 300mg
- 200ml of milk (skimmed, semi-skimmed or whole) has a calcium value of 200mg
- 200ml of soya milk (calcium boosted) has a calcium value of 200mg
- 125g (1 pot) of yogurt (low-fat fruit, plain) has a calcium value of 200mg
- 50g of sardines (canned) has a calcium value of 200mg
- 30g of cheddar cheese has a calcium value of 200mg
- 2 dried figs (40g) have a calcium value of 100mg
- 1 small tin of baked beans (equivalent to 200g) has a calcium value of 100mg
- Half a plain naan bread (43g) has a calcium value of 100mg
- 110g of steamed broccoli has a calcium value of 50mg
- 10 whole almond nuts (22g) have a calcium value of 50mg
- 9 whole Brazil nuts (30g) have a calcium value of 50mg
There are calculator tools online that can tell you how much calcium is in the foods you eat.
Vitamin D is needed to help your body absorb calcium. You can get vitamin D from:
The main source is sunlight, which your body uses to make this vitamin in your skin.
From April to September, the light from the sun is strong enough that we can make vitamin D on exposed skin such as the face, legs, and arms. However, make sure you stay safe in the sun.
The body stores vitamin D for use during the winter months, but it’s recommended that all adults take a vitamin D supplement especially in the winter months. Some people may not get enough vitamin D from sunlight because of little or no exposure to the sun. If this is the case, your doctor may recommend you take a vitamin D supplement throughout the year. The recommended dose of vitamin D is 10 micrograms (400 International Units (IU)) per day.
You can get some vitamin D from food. However, even if you have a healthy and well-balanced diet that provides all the other vitamins and goodness you need, it’s unlikely to provide enough vitamin D. Good sources of vitamin D in food include:
- Egg yolks
- Red meat
- Oily fish such as herrings and sardines
- Cod liver oil
- Margarine, yoghurts and breakfast cereals that have added vitamin D (vitamin D-fortified)
Drinking too much alcohol can affect your bone strength and thickness (density). Also regularly drinking alcohol increases the risk of developing breast cancer, although it’s less clear if this affects the outlook (prognosis) for people who have had breast cancer. NICE (National Institute for Health and Care Excellence) recommend people who have had breast cancer limit their alcohol intake to below five units per week.
You can find out how many units are in your drinks by using an online unit calculator. As a general guide:
- A can of beer or cider (440ml, 5.5%) = 2 units
- A 175ml glass of wine (12.5%) = 2.1 units
- A single 25ml measure of spirits (40%) = 1 unit
4. Physical activity
Exercise and breast cancer
Regular physical activity and exercise are important for managing osteoporosis. Regular weight-bearing exercise or activities help stimulate growth and maintain the strength of the bones and muscles. Weight-bearing exercise is any exercise where you support the weight of your own body. Weight-bearing exercises can be moderate-impact or low-impact.
- Stair climbing
- Cross training machines
The type of activity you do will depend on your individual needs and current abilities. For example, your fitness levels, any effects of treatment or other health problems you might have.
If you have osteoporosis and have a high fracture risk, you may need to change your exercises and avoid any awkward or sudden bending and twisting because of a higher chance of injury.
The Royal Osteoporosis Society has information on exercise for bone health.
You should speak to your GP or treatment team before starting any new exercise routine. They may refer you to a physiotherapist if you need extra guidance or support.
