Dr Caroline Leaf and osteoporosis – Brittle facts on brittle bones

In the fifteenth chapter of his gospel account, Matthew described a conversation that Jesus had with his disciples. Jesus had just reprimanded the Pharisees for their hypocrisy, and the disciples came back to Jesus to report that the Pharisees weren’t very happy about it.

“Then the disciples came to him and asked, ‘Do you know that the Pharisees were offended when they heard this?’ He replied, ‘Every plant that my heavenly Father has not planted will be pulled up by the roots. Leave them; they are blind guides. If the blind lead the blind, both will fall into a pit.’” (Matthew 15:12-14)

When it comes to many subjects, Dr Leaf is a blind guide. Dr Caroline Leaf is a communication pathologist and self-titled cognitive neuroscientist. She’s not a medical doctor – her title is academic, an award for her PhD in communication pathology over twenty years ago. She has no medical training whatsoever, which makes it a little offensive when she feels she’s qualified to lecture people about medical conditions like osteoporosis.

In an episode of her TV show broadcast this week, Dr Leaf offered a B-grade attempt at mimicking Dr Oz by trying to use her biased ideology to explain a serious medical condition, and in so doing, gave a performance laden with droll irony, a example of the Dunning-Kruger effect in its purest form.

Her co-host was Dr Avery M. Jackson III, a neurosurgeon in Michigan, who Google confuses with Dr Jackson Avery of Grey Sloan Memorial Hospital fame. Dr Jackson has an impressive bio which is replete with advanced work on osteoporotic crush fractures of the spine. One wonders why a specialist of such high regard would associate himself with a scientific philistine who doesn’t understand how genes work, and who regularly contradicts her own position.

Or why he would allow Dr Leaf to publicly associate him with claims like:
“Osteoporosis can be caused by bad thinking and bad eating”,
Not only is it considered a silent epidemic, but (osteoporosis) has its roots in mind and lifestyle choices”, and
“much can be done on a preventative level like diet and starting young with lifestyle choices and the way we use our minds. Mind is involved in everything!”

Actually, the biggest contributors to the risk of osteoporosis are genetics, ageing and the loss of gonadal function (menopause or low testicular function). Which of these are controlled by the mind, Dr Leaf? It’s not that lifestyle has no influence on osteoporosis, but Dr Leaf overstates the case.

If you want some useful advice on osteoporosis, I’d encourage you to get your information from reputable experts, not wannabe experts like Dr Leaf. To reduce your risk of developing osteoporosis, Osteoporosis Australia recommends
* 3-5 serves of calcium rich food daily
* adequate sunlight
* regular weight bearing exercise

Dr Leaf needs to move on from her unscientific premise that the mind is in control of everything. It’s patently false, and it terminally biases nearly everything she says. She needs to open her scientific eyes rather than staying blind to the truth.
