These 8 things could be making your bones brittle – how to avoid them


We don’t tend to think about our bone health until there’s a problem. For most of us, the first sign anything is wrong is after a fall that results in a broken bone. Some 50,000 falls leading to fractures occur in the UK each year – and too often what follows is the surprise discovery a person has the bone-thinning disease osteoporosis.

Around 3.5 million people are living with the condition, and a further one million have low bone density (osteopenia), putting them at increased risk of painful and ­potentially life-altering fractures.

The issue is widespread, with one in two women over the age of 50 suffering a fracture from osteoporosis and one in four men. And we’re not just talking about the elderly. Hormone expert Dr Nicky Keay, Honorary Clinical Lecturer at University College London and author of Myths of Menopause, says: “Your skeleton is made up of bones that provide your body with support, ­structure, stability and protection for vital organs.

“Bones also interact with muscles to enable movement, store minerals such as calcium, phosphorus and magnesium, and some long bones contain marrow in which new red and white blood cells are made.”

Here are key bone-strength stealers that could be raiding your reserves – and how to manage them.

Years of yo-yo dieting:

“Repeatedly losing and regaining weight over many years can reduce your bone density,” says Lorna Cooke, dietitian at the Sports Institute of Northern Ireland. “When you restrict food, key hormones needed to maintain bone can be affected. A lack of nutrients such as calcium when following restrictive diets can also lead to long-term deficiencies – because when the body doesn’t get enough calcium from food, it takes it from bones, which weakens them over time.”

What to do: “Gradual weight loss is safer when it comes to protecting bone health,” adds Lorna. “By eating regular, well-­balanced meals, healthy habits can be sustained, meaning the weight is more likely to stay off in the long run.”

Too little time outside:

“One of the major causes of ­osteoporosis is lack of vitamin D – the sunshine vitamin, made by the action of sunlight on skin,” says Dr Eamon Laird, vitamin D researcher at Trinity College Dublin. “Deficiency is common during winter as we can’t make enough in the Northern Hemisphere, so we rely on supplementation because diet alone can’t provide what we need.”

What to do: Rob Hobson, nutritionist at Healthspan, says: “For adults, taking a vitamin D supplement of 10 µg or more is recommended in winter – and all year round for those over 65, who don’t get outside much or have other risk factors.”

Menopause matters:

After menopause, bone loss accelerates due to falling oestrogen – particularly oestradiol – which normally helps slow bone breakdown. Women can lose up to 0.5% of bone density each year. By their mid-40s, many have lost a significant amount.

What to do: Tania Adib, Consultant Gynaecologist at The Medical Chambers Kensington, says: “Building strong bones early and protecting them through menopause is key. I believe women around 45 should be offered a DXA scan to check bone density. Prioritise weight-bearing exercise, good sleep and a healthy weight. HRT can be effective to prevent bone loss in the right women – especially those with early menopause or severe symptoms.”

Ultra-processed foods:

“Calcium and vitamin D-rich diets are essential for maintaining bone density,” says Healthspan nutritionist Rob. “The nutrient-deficient nature of a diet high in ultra-processed foods may negatively impact bone health. UPFs often lack the vitamins and minerals essential for strong bones.”

What to do: “To protect your bones, try to limit the amount of UPFs you eat each day and make more meals from scratch,” adds Rob. “A balanced diet that prioritises unprocessed whole foods – including wholegrains, protein, fruit, vegetables and healthy fats – provides the nutrients bones need to remain strong and healthy at all stages of life.”

Long-term meds or illness:

Some conditions, such as a hyperactive thyroid, can increase the body’s natural rate of bone loss. A booklet by Viridian Nutrition with GP Dr Siobhan Brennan, Medication + Nutrition For Optimal Support, explores the medications that can impact bone health, including some weight-loss drugs, steroids, cancer drugs, antidepressants and proton-pump inhibitors.

What to do: Ask your GP or pharmacist for a medicine review and check visit viridian-nutrition.com for more details.

Ditching dairy:

“Milk and dairy products such as cheese and yogurt are great sources of calcium,” says Lorna. “Excluding them from your diet due to veganism or health concerns can lead to deficiencies in calcium and vitamin D – and a greater risk of osteoporosis.”

What to do: Adults need around 1,000 mg of calcium daily. “If you’re cutting out dairy, replace it with calcium-rich alternatives such as fortified foods (bread, non-dairy milks), plant-based proteins (tofu, nuts and seeds), leafy greens, dried fruit and pulses,” says Lorna. “A supplement can help.” Try Healthspan Osteo Complete Bone Support, 240 tablets, £22.99, healthspan.co.uk

Gut diseases:

“The intestinal damage caused by Crohn’s disease or colitis, if left untreated, can lead to poor absorption of key nutrients like calcium and vitamin D – which long-term can lead to osteoporosis,” explains Lorna.

What to do: “Early diagnosis, and in some cases a strict diet advised by a dietitian, is key in allowing the intestinal lining to repair and start absorbing nutrients again,” says Lorna. “People may be prescribed calcium and vitamin D supplements.” A bone scan on diagnosis is also a good idea.

Too much or too little exercise:

Physical activity is vital for bone health, but the right type and amount is key. Those who aren’t active are at higher risk for bone loss, but those who over-exercise are too. “Most of us do too little, and our risk of brittle bones much earlier in life as young as our 30s and 40s – increases if we do next to no physical activity,” explains Dr Laird at Trinity College Dublin.

What to do: “Adults should aim for at least 30 minutes of activity per day, including weight-bearing exercises – where your feet and legs support your weight – such as walking or jogging, to strengthen and maintain bone health,” says Dr Laird.
