How to protect your bones if you're a vegetarian

According to new research, women who follow a vegetarian diet have a higher risk of breaking their hips in later life. Imy Brighty-Potts investigates...

GOING vegetarian is a popular way to help your health and the planet, but it seems it may make you more likely to break a hip.

Researchers have said that vegetarian diets "often have lower intakes of nutrients that are linked with bone and muscle health" after their study found that female vegetarians had a 33 per cent increased risk of hip fracture in comparison to regular meat eaters.

The study, which involved more than 26,000 women aged 35-69 from across the UK, assessed the risk of hip fracture among vegetarians, pescatarians, and occasional meat eaters compared with regular meat eaters - and the elevated risk of hip fracture was only found among vegetarians.

However, a plant-based diet is often cited to have big health benefits too.

"A whole food plant-based diet can reduce inflammatory markers and the risk of the most common chronic diseases. This way of eating promotes health and longevity by maximising healthy nutrients and minimising harmful components," says Dr Rajiv Bajekal, a consultant orthopaedic surgeon and lifestyle medicine physician at Plant Based Health Professionals UK.

"Centring your meals around wholegrains, beans, fruit, vegetables, nuts and seeds offers mental and physical benefits both in the short-term and in the longer term."

So, what can vegetarians and vegans do to ensure they are getting all the good stuff and giving their bones the best possible support?

1. FIND PLENTY OF PROTEIN

"Bones need protein to be strong and we can get high quality protein in our food from beans, especially soya, and also foods such as quinoa, nuts and seeds," says Bajekal.

"Look for calcium-set tofu, tempeh and calcium-fortified soya milk and try and get two to three portions of these foods or other beans daily.

"Soya is particularly beneficial as it is a great source of protein, micronutrients and also phytoestrogens that are bone protective. Fruit and vegetables also promote bone formation."

2. ENOUGH CALCIUM IS VITAL - ESPECIALLY DURING THE MENOPAUSE

At different times of our life, our bodies may need different things.

"Our maximum bone strength is around 30 years of age after which there is a steady fall in bone strength. If we build up more of a reserve before this age by being very active, we can lose more bone without the problems of osteoporosis in later life," explains Bajekal.

"During the perimenopause, one can lose as much as 3-5 per cent of our bone mass and strength due to the loss of the protective effect of oestrogen and it is important that women in particular think of how to get into their golden years in the best possible way to prevent this sudden loss of bone."

To mitigate this, during the menopausal years, it's key to focus on calcium rich foods, he adds, "Which can be obtained from calcium set tofu, calcium fortified plant milks, white beans, tahini and green leafy vegetables such as kale, boy choy, rocket and broccoli.

"Calcium losses are greater in people who smoke, consume excess amounts of coffee, alcohol or sugar sweetened beverages, and also consume excess salt in the diet usually present in ultra-processed foods."

Calcium will help people of all ages support bone health though so it's always worth making sure you're getting enough.

3. FOCUS ON STRENGTH-BASED EXERCISE

The exercise we do will also have an impact on our bone health.

"Walking is helpful to prevent bone loss but doesn't increase bone strength. Walking with a weighted jacket or wrist and ankle weights helps stimulate bone formation," says Bajekal.

"Skipping, star jumps, and training with weights helps strengthen bones and using an all-body vibration platform to do weight training can also help.

"Building leg strength and doing tai chi or other balance training exercises goes a long way in preventing falls and should not be neglected. Muscle strength and bone strength go together in this regard."

4. ADD OTHER ESSENTIAL VITAMINS

If you are vegetarian, it's crucial to make sure you're getting enough vitamin D and B12 - which Bajekal says are "essential for bone health and helping prevent falls and must be supplemented in plant-based diets".

So get out in the sunshine and eat spinach, eggs and cheese to boost your levels of both - and consider taking a supplement, especially in winter.
