“OUT OF MY WHEELCHAIR AND BACK ON MY BIKE”: HOW DR TERRY WAHLS BEAT MULTIPLE SCLEROSIS
In 2000, Dr Terry Wahls, a University of Iowa professor of internal medicine, was diagnosed with secondary progressive multiple sclerosis, a stage where symptoms steadily worsen and disability is expected to increase. By 2003, she was confined to a wheelchair, unable to sit upright for more than minutes at a time, and struggling to feed herself.
“Once lost, functions are gone forever,” she says. “By 2007, I was constantly exhausted and had increasingly severe bouts of trigeminal neuralgia - intense jolts of electrical face pain that were harder and harder to stop.
Conventional treatments failed to halt her decline but determined to change her trajectory, she immersed herself in medical research, focusing on mitochondrial dysfunction in neurodegeneration.
“I decided to self-experiment, hoping, if I was lucky, to slow the progression of my MS. As a doctor, I certainly did not expect to walk around the hospital again making my rounds. Or go hiking or biking again.
“By identifying the key nutrients important to brain health, I maximised my intake of the nutrients I’d been taking in supplement form - getting them instead directly from the food I ate.
“Each day I consumed three platefuls of green leafy vegetables, sulphur-rich and deeply pigmented vegetables, and ate meat in moderation while eliminating gluten-containing grains, eggs, dairy and legumes. I also added fermented foods, full of good bacteria for digestive health, mineral-rich seaweed and more nutrient-dense organ meats.
“Three months after starting the diet, my fatigue was gone. The electrical face pains were gone too. I began doing my hospital rounds using a cane. After six months, I began walking without a cane. At nine months I got on my bike again for the first time in six years and rode around the block. After 12 months of this new way of feeding my cells, I biked 18 miles with my family. If I went off the diet, the electrical face pains came back within 24 hours.”
Dr Wahls has now been gifted $2.5 million from the Carter Chapman Shreve Family Foundation to investigate her diet and its effects on improving quality of life and reducing fatigue, in those with relapsing-remitting MS.
The gift will allow Wahls and her team to conduct one of the largest dietary intervention studies ever completed in people with MS.
