With bone structure problems such as osteoporosis affecting millions, it is increasingly important to look after our bone health.

As we age, our bone density reduces because we lose calcium and other minerals making them thinner and more brittle. Women can be even more vulnerable due to menopause, as the drop in oestrogen during the process causes the bones to weaken.

Jogging, climbing stairs, tennis and other weight-bearing exercises can offset the problem, as they help to increase our storage of calcium. This is the mineral that helps to strengthen the bone structure. Eating calcium-rich foods also has a huge impact on our bone health.

Here are some calcium rich foods to eat this winter to enhance bone strength:

1. Tofu

Not just for vegetarians and vegans, tofu is an excellent source of calcium – about 200mg in a 60g serving. Don’t like the wobbly texture? Try scrambling soft tofu with courgette, mushrooms, peppers and some ground spices for a delicious high-protein, low-fat dish. Or buy the firm variety and toss it into your stir-fry.

2. Edamame or soya beans

Edamame beans are packed with 200mg calcium per serving. Buy them at the supermarket (you can buy them frozen, too) for a great snack on the go.

3. Bony fish

Fish such as sardines, pilchards and canned salmon contain up to a third of our daily calcium needs – the tiny, edible bones are a great calcium source. They also provide a boost of omega 3s for brain and heart health and will help you with your vitamin D intake, which is necessary for us to absorb calcium. Try serving with a green salad, or stuffed into a pitta with leaves and cucumber.

4. Okra

This veg is also known as ladies’ fingers because of its long shape. Often used in African stews or Asian dishes, okra has a similar taste and texture to aubergine and a serving contains around 82mg calcium. You’ll find it in most international supermarkets. Try it in a curry or soup – the longer you cook it, the gooier the texture!

5. Green leafy vegetables

Vegetables such as broccoli, kale, bok choi and spring greens provide both high levels of calcium (around 245mg in a serving of kale), and plenty of vitamin K and folate – key for bone strength. Try steaming lightly alongside fish or chicken seasoned with spices or citrus.

6. Milk, cheese and yogurt

Unsurprisingly, dairy products are the richest and best-known source of calcium. A serving of yogurt, cheese or milk provides between 150-250mg of it. Skimmed milk contains more calcium than whole – but have it without your cuppa every now and again as caffeine can reduce calcium absorption. Hard cheeses contain more calcium than soft, with parmesan top of the leaderboard.

7. Calcium-fortified foods

There are a range of calcium-fortified products on the market including cereals, breads and drinks such as orange juice – look out for the labels! For those on dairy-free diets, oat, rice and soya milks tend to be fortified with calcium too.

And don’t forget to dose up on vitamin D…

Vitamin D is needed for our bodies to absorb calcium, and the best source is sunlight. Being outside in the warmer months three times a week for just 15 minutes should be enough for most people. It is advisible that elderly and pregnant and breastfeeding women might consider taking a 10mcg supplement of vitamin D during the autumn and winter months.
