Vegans 40pc more likely to suffer from fractures from lack of calcium,
Oxford study finds

Vegans are 40 per cent more likely to suffer from a bone fracture due to a
lack of calcium and protein than meat eaters, a Oxford University study has
found.

The study of more than 50,000 British people tracked over two decades found
that giving up meat can weaken bones and even trigger osteoporosis.

Researchers found that people with lower calcium and protein intakes who
had vegan diets were more prone to hip, leg and spinal fractures.

They also found that vegans were 43 per cent more likely to suffer a
fracture anywhere - particularly in the leg, vertebrae and collarbone.

Study lead author Dr Tammy Tong, an Oxford University nutritional
epidemiologist, said: "The biggest differences were for hip fractures,
where the risk in vegans was 2.3 times higher than in people who ate meat -
equivalent to 15 more cases per 1,000 people over 10 years."

It is the most common serious injury in older people. There are more than
76,000 cases a year, costing the NHS £1 billion annually.

Women are most vulnerable because their bones naturally lose strength after
the menopause as levels of oestrogen drop.



Dr Tong said: "We found vegans had a higher risk of total fractures which
resulted in close to 20 more cases per 1000 people over a 10-year period
compared to people who ate meat."

Participants' diets were assessed initially, and then again in 2010. They
were followed up until 2016, for 18 years on average, for the occurrence of
fractures.

Fracture risk was partly reduced once BMI (body mass index) and dietary
calcium and protein consumption had been taken into account.

Dr Tong explained: "Vegetarians and vegans generally have lower BMI than
meat eaters.

"This is associated with a higher risk of hip fractures, and low intakes of
calcium and protein have both been linked to poorer bone health."

Possible explanations include the cushioning against impact force during a
fall, enhanced oestrogen production with increased adiposity or stronger
bones from greater weight-bearing.

Dr Tong said: "This study showed vegans, who on average had lower BMI as
well as lower intakes of calcium and protein than meat eaters, had higher
risks of fractures at several sites.



"Well-balanced and predominantly plant-based diets can result in improved
nutrient levels and have been linked to lower risks of diseases including
heart disease and diabetes.

"Individuals should take into account the benefits and risks of their diet,
and ensure they have adequate levels of calcium and protein and also
maintain a healthy BMI, that is, neither under nor overweight."

The study looked at participants recruited between 1993 and 2001, with
29,400 meat eaters, 17,500 vegetarians and vegans, and 8,000 pescatarians.

During the study a total of 3,941 fractures occurred, including almost
1,000 hip fractures as well as those to the wrist, arm, leg and ankle.

The authors found no significant difference in risk between groups for arm,
wrist and ankle fractures once BMI was taken into account.

Dr Tong added: "Fractures in adulthood and older ages are a common
occurrence which pose a significant burden to health systems worldwide.

"Previous epidemiological studies have shown that vegetarians had lower
bone mineral density than non-vegetarians, but the associations of
vegetarian diets with fracture risks are unclear.


"Potential risk differences are plausible however,owing to differences in
several dietary factors, such as the substantially lower intakes of calcium
in vegans, lower intakes of dietary protein in both vegetarians and vegans,
and the lower BMI of non-meat eaters."

Vegans tend to have lower cholesterol. Cholesterol is required to make
vitamin D in our skin.

(My own cholesterol is very low - despite not being a vegetarian, let
alone a vegan. And consuming significant quantities of butter, cheese and
other fats. I take a vitamin D3 supplement.)

There has been a lot of discussion recently about the role of vitamin D
in Covid-19 with low vitamin D being associated with BAME medical staff
and deaths. Unofficial advice to supplement with vitamin D among BAME
doctors appears to have had a profound impact on death rates.

Remember: Cows have massive bones and are vegetarian.

Still there are difficulties for those who are unable to tolerate vitamin D
supplementation.


There was a comment made during one the coverage of the higher incidence of
the virus in parts of Europe and the BAME community that both had lower
vitamin D and some of the BAME community had a naturally high cholesterol
level.

Not all vegetarian animals have big bones it is more related to animal
size. A rabbit has small bones.

It's the famed area/volume ratio: responsible for elephants having
massive limbs, flying animals being relatively small and the critical
mass needed for an atom bomb to explode.


Of course it is vegans just cant accept their diet is fundamentally
unhealthy.
